Abstract
This study investigates the application of visible-short wavelength near-infrared hyperspectral imaging (Vis-SWNIR HSI) in the wavelength range of 400-950 nm and advanced chemometric techniques for diagnosing breast cancer (BC). The research involved 56 ex-vivo samples encompassing both cancerous and non-cancerous breast tissue from females. First, HSI images were analyzed using multivariate curve resolution-alternating least squares (MCR-ALS) to exploit pure spatial and spectral profiles of active components. Then, the MCR-ALS resolved spatial profiles were arranged in a new data matrix for exploration and discrimination between benign and cancerous tissue samples using principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA). The PLS-DA classification accuracy of 82.1 % showed the potential of HSI and chemometrics for non-invasive detection of BC. Additionally, the resolved spectral profiles by MCR-ALS can be used to track the changes in the breast tissue during cancer and treatment. It is concluded that the proposed strategy in this work can effectively differentiate between cancerous and non-cancerous breast tissue and pave the way for further studies and potential clinical implementation of this innovative approach, offering a promising avenue for improving early detection and treatment outcomes in BC patients.

Abstract
In this work, molecular descriptors of N-(1-(2-bromobenzoyl)-4-cyano-1H-pyrazol-5-yl) halogenated benzamides (1a-h) have been computed using a quantum chemical technique through DFT. Prior work involved the synthesis of compounds (1a-h) and the assessment of their anticancer activity on breast, colon, and liver tumors: MCF-7, HCT-116, and HepG-2 cell lines respectively. Since 1a, 1b, and 1d showed the most potential anticancer impact, their ability to inhibit EGFRWT was investigated. Based on the biological data, 1b inhibited EGFRWT the most. According to the docking evaluation, an H-bond with the threonine residue was one of the main non-covalent contacts between 1b and the EGFRWT active site residues. PES, MESP, HOMOs, LUMOs, energy band gap, global reactivity indices [electron affinity (A), ionization energies (I), electrophilicity index (ω), nucleophilicity index (ε), chemical potential (μ), electronegativity (χ), hardness (η), and softness (S)], condensed Fukui functions, NBO, and NCIs are the molecular descriptors of 1a-h that were computed using DFT technique. According to the theoretical investigation results, compounds (1a-h) might have anticancer effects; these findings are consistent with the biological findings from our previous research. Compound 1b had the lowest binding energy, according to an assessment of the binding energies between the threonine and the three most active compounds (1a, 1b, and 1d). This is consistent with the outcomes of the docking study and the biological examination of the influence of 1a, 1b, and 1d on EGFRWT.

Abstract
CONTEXT Podophyllotoxin (PPT) derivatives, used in cancer therapy, require development toward enhanced efficacy and reduced toxicity. OBJECTIVE This study synthesizes PPT derivatives to assess their anticancer activities. MATERIALS AND METHODS Compounds E1-E16 antiproliferative activity was tested against four human cancer cell lines (H446, MCF-7, HeLa, A549) and two normal cell lines (L02, BEAS-2B) using the CCK-8 assay. The effects of compound E5 on A549 cell growth were evaluated through molecular docking, in vitro assays (flow cytometry, wound healing, Transwell, colony formation, Western blot), and in vivo tests in female BALB/c nude mice treated with E5 (2 and 4 mg/kg). E5 (4 mg/kg) significantly reduced xenograft tumor growth compared to the DMSO control group. RESULTS Among the 16 PPT derivatives tested for cytotoxicity, E5 exhibited potent effects against A549 cells (IC50: 0.35 ± 0.13 µM) and exceeded the reference drugs PPT and etoposide to inhibit the growth of xenograft tumours. E5-induced cell cycle arrest in the S and G2/M phases accelerated tubulin depolymerization and triggered apoptosis and mitochondrial depolarization while regulating the expression of apoptosis-related proteins and effectively inhibited cell migration and invasion, suggesting a potential to limit metastasis. Molecular docking showed binding of E5 to tubulin at the colchicine site and to Akt, with a consequent down-regulation of PI3K/Akt pathway proteins. DISCUSSION AND CONCLUSIONS This research lays the groundwork for advancing cancer treatment through developing and using PPT derivatives. The encouraging results associated with E5 call for extended research and clinical validation, leading to novel and more effective cancer therapies.

Abstract
Novel magnetic and metallic nanoparticles garner much attention of researchers due to their biological, chemical and catalytic properties in many chemical reactions. In this study, we have successfully prepared a core-shell Fe3O4@SiO2@PDA nanocomposite wrapped with Ag using a simple synthesis method, characterised and tested on small cell lung cancer and antibacterial strains. Incorporating Ag in Fe3O4@SiO2@PDA provides promising advantages in biomedical applications. The magnetic Fe3O4 nanoparticles were coated with SiO2 to obtain negatively charged surface which is then coated with polydopamine (PDA). Then silver nanoparticles were assembled on Fe3O4@SiO2@PDA surface, which results in the formation core-shell nanocomposite. The synthesised nanocomposite were characterized using SEM-EDAX, dynamic light scattering, XRD, FT-IR and TEM. In this work, we report the anticancer activity of silver nanoparticles against H1299 lung cancer cell line using MTT assay. The cytotoxicity data revealed that the IC50 of Fe3O4@SiO2@PDA@Ag against H1299 lung cancer nanocomposites cells was 21.52 µg/mL. Furthermore, the biological data of nanocomposites against Gram-negative 'Pseudomonas aeruginosa' and Gram-positive 'Staphylococcus aureus' were carried out. The range of minimum inhibitory concentration was found to be 115 µg/mL where gentamicin was used as a standard drug. The synthesized AgNPs proves its supremacy as an efficient biomedical agent and AgNPs may act as potential beneficial molecule in lung cancer chemoprevention and antibacterial strains.

Abstract
The prognosis for esophageal squamous cell carcinoma (ESCC), a prevalent and aggressive form of cancer, remains poor despite advancements in treatment options. Addressing the gap in comprehensive prognostic information derived from circRNA expression profiles for ESCC, our study aimed to establish a linkage between circRNA expressions and ESCC prognosis. To achieve this, we first developed an optimized prognostic model named T cell-related risk score (TRRS), which integrates T cell-associated features with machine learning algorithms. In parallel, we re-analyzed existing RNA-seq datasets to redefine the expression profiles of circRNAs and mRNAs. Utilizing the TRRS as a foundational "bridge," we identified circRNAs correlated with TRRS, leading to the development of a novel circRNA pair-based prognostic model, the TCRS, which is independent of specific expression levels. Further investigations uncovered two circRNAs, circNLK(5,6,7).1 and circRC3H1(2).1, with potential functional significance. These findings underscore the utility of these risk scores as tools for predicting overall survival and identifying potential therapeutic targets for ESCC patients.

Abstract
OBJECTIVE This study aims to evaluate the effectiveness of a self-management program using gain/loss-framed messages in patients with gastric cancer. METHODS In this randomized controlled trial, 69 patients with gastric cancer who underwent gastrectomy at a university hospital were assigned to the gain- or loss-framed message group. The self-management program consisted of: 1) face-to-face education, 2) gain/loss-framed text messages, and 3) self-monitoring of health behaviors. Health outcomes (i.e., nutritional status, physical activity, exercise intensity, and distress), and health behaviors (i.e., dietary habits, physical activity performance, and distress management) were measured, and a generalized estimating equation was used for the analysis. RESULTS Nutritional status and dietary habits in the loss framed message group were statistically higher after the intervention compared to the counterpart (β = -1.72, p = .049; β = 0.36, p = .033, respectively). There was no time-group interaction effect on physical activity, exercise intensity, physical activity performance, distress or distress management. CONCLUSIONS A self-management program employing loss-framed messages was effective in promoting nutrition-related self-management among patients with gastric cancer. PRACTICE IMPLICATIONS Message-framing is an effective communication technique that can be easily used in clinical settings, and a loss-message-framing strategy may enhance nutrition-related self-management in patients with gastric cancer.

Abstract
Despite recent advances in the treatment of cancer, the issue of therapy resistance remains one of the most significant challenges in the field. In this context, signaling molecules, such as cytokines have emerged as promising targets for drug discovery. Examples of cytokines include macrophage migration inhibitory factor (MIF) and its closely related analogue D-dopachrome tautomerase (D-DT). In this study we aim to develop a new chemical class of D-DT binders and subsequently create a dual-targeted inhibitor that can potentially trigger D-DT degradation via the Proteolysis Targeting Chimera (PROTAC) technology. Here we describe the synthesis of a novel library of 1,2,3-triazoles targeting D-DT. The most potent derivative 19c (IC50 of 0.5 ± 0.04 μM with high selectivity toward D-DT) was attached to a cereblon (CRBN) ligand through aliphatic amides, which were synthesized by a remarkably convenient and effective solvent-free reaction. Enzyme inhibition experiments led to the discovery of the compound 10d, which exhibited moderate inhibitory potency (IC50 of 5.9 ± 0.7 μM), but unfortunately demonstrated no activity in D-DT degradation experiments. In conclusion, this study offers valuable insight into the SAR of D-DT inhibition, paving the way for the development of novel molecules as tools to study D-DT functions in tumor proliferation and, ultimately, new therapeutics for cancer treatment.

Design and synthesis of novel Thiazolo[5,4-b]pyridine derivatives as potent and selective EGFR-TK inhibitors targeting resistance Mutations in non-small cell lung cancer. Eur J Med Chem 2024; 276:116727.

Abstract
A novel series of substituted thiazolo[5,4-b]pyridine analogues were rationally designed and synthesized via a multi-step synthetic pathway, including Suzuki cross-coupling reaction. The anticancer activity of all forty-five synthesized derivatives was evaluated against HCC827, H1975, and A549 cancer cell lines utilizing the standard MTT assay. A significant number of the thiazolo[5,4-b]pyridine derivatives exhibited potent anticancer activity. Notably, compounds 10b, 10c, 10h, 10i, and 10k emerged as the most promising anticancer agents. The lead compound, N-(3-(6-(2-aminopyrimidin-5-yl)thiazolo[5,4-b]pyridin-2-yl)-2-methylphenyl)-2,5-difluorobenzenesulfonamide (10k), displayed remarkable potency with IC50 values of 0.010 μM, 0.08 μM, and 0.82 μM against the HCC827, NCI-H1975 and A-549 cancer cell lines, respectively, which were comparable to the clinically approved drug Osimertinib. Importantly, the potent derivatives 10b, 10c, 10h, 10i, and 10k exhibited selective cytotoxicity towards cancer cells and showing no toxicity against the normal BEAS-2B cell line at concentrations exceeding 35 μM. Mechanistic studies revealed that the active compound 10k acts as an EGFR-TK autophosphorylation inhibitor in HCC827 cells. Furthermore, apoptosis assays demonstrated that compound 10k induced substantial early apoptosis (31.9 %) and late apoptosis (8.8 %) in cancer cells, in contrast to the control condition exhibiting only 2.0 % early and 1.6 % late apoptosis. Molecular docking simulations of the synthesized compounds revealed that they formed essential hinge interactions and established hydrogen bonding with Cys797, indicating potential target engagement. These findings highlight the potential of the synthesized thiazolo [(Woodburn, 1999; Zigrossi et al., 2022) 5,45,4-b]pyridine derivatives as promising anticancer agents, warranting further investigation for the development of novel targeted therapies against non-small cell lung cancer.

Gastric cancer (GC) is the fourth leading cause of cancer death in the world, and there is a demand for new therapeutic agents to treat GC. Metformin has been demonstrated to be an antineoplastic agent in some types of cancer; however, it has not been sufficiently valued in treating GC because the effect of metformin in combination with chemotherapy regimens has not yet been evaluated. The present study aimed to evaluate the mechanisms underlying cell death induced by metformin alone or when combined with chemotherapy. The cytogenetic characteristics of the NCI-N87 cell line were determined by fluorescence in situ hybridization (FISH). To determine viability, the cells were treated with metformin, epirubicin, cisplatin, docetaxel and 5-fluorouracil (individually and at different concentrations). Subsequently, the cells were treated with metformin alone, and in combination with the chemotherapeutic drugs and the epirubicin + cisplatin + 5-fluorouracil, docetaxel + cisplatin + 5-fluorouracil, and cisplatin + 5-fluorouracil regimens. Cell viability, proliferation and mitochondrial membrane potential (ΔΨm) were analyzed by spectrophotometry. Apoptosis, caspase activity and cell cycle progression were assessed by flow cytometry. Finally, light microscopy was used to evaluate senescence and clonogenicity. The results revealed that metformin, alone and when combined with chemotherapy, increased the proportion of apoptotic cells, promoted the loss of ΔΨm, and induced apoptosis through caspase activity in GC cells. Moreover, metformin decreased cell proliferation. In addition, metformin alone did not induce senescence and it counteracted the effects of chemotherapy-induced senescence in GC cells. Additionally, metformin, alone and when combined with chemotherapy, decreased the clonogenic capacity of NCI-N87 GC cells. In conclusion, metformin may increase the effects of chemotherapy on NCI-N87 cell death and could represent an option to improve the treatment of GC.

Zhou B, Gek Mui L, Li J, Hu J. The impact of mindfulness-based interventions on the experiences of cancer patients: A qualitative meta-synthesis. PATIENT EDUCATION AND COUNSELING 2024; 127:108353. [PMID: 38964172 DOI: 10.1016/j.pec.2024.108353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 06/03/2024] [Accepted: 06/14/2024] [Indexed: 07/06/2024]
Abstract
OBJECTIVE This study analyzed qualitative research to explore cancer patients' perspectives on MBIs, including benefits, challenges, and recommendations. METHODS This systematic review focused on synthesizing qualitative data and was registered with PROSPERO under the protocol registration number xxx. Searched 7 databases for qualitative studies on MBIs & cancer patients (17 studies, 365 patients). Analyzed data using themes & assessed confidence in findings. RESULTS Thematic analysis using NVivo software revealed four significant themes: (1) benefits and positive outcomes (e.g., symptom improvement, team support, positive experiences), (2) challenges and difficulties (e.g., practice challenges, negative experiences), (3) the journey of change and acceptance (e.g., shifts in perception, personal growth, and acceptance), and (4) adaptations and recommendations (e.g., program modification and flexibility). CONCLUSION Mindfulness-based interventions have the potential to offer cancer patients positive emotional experiences, increased team support, and opportunities for personal growth, self-discovery, and acceptance. This, in turn, can help them manage the psychological distress associated with cancer. Customizing programs to align with individual patients' needs and preferences can enhance engagement and effectiveness. PRACTICE IMPLICATIONS Integrating MBIs into Patient Education and Counseling, tailored to individual needs and with ongoing support, can enhance cancer care. Group interventions foster peer support and effectiveness. Training providers and ensuring accessibility are crucial. Research and customization to patients' journeys optimize outcomes and satisfaction. A patient-centered approach is essential for positive experiences and improved clinical outcomes.

A surveillance study of cancer incidence and mortality among young adults in Costa Rica. LANCET REGIONAL HEALTH. AMERICAS 2024; 38:100872. [PMID: 39280883 PMCID: PMC11399702 DOI: 10.1016/j.lana.2024.100872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 07/11/2024] [Accepted: 08/09/2024] [Indexed: 09/18/2024]
Abstract
Background There has been an increase in certain cancers among young adults (YA) aged 20-39, particularly in Latin America. This is the first study to examine cancer incidence and mortality in YA in Costa Rica, focusing on sex-specific patterns. Methods Invasive cancer cases (excluding non-melanoma skin cancer) in YA from 2006 to 2015 were obtained from the Costa Rican National Registry of Tumors. Utilising SEER∗Stat software, age-standardized incidence rates (IRs) and incidence rate ratios (IRRs) were calculated. Trends and annual percent changes (APCs) in IRs were estimated using the Joinpoint regression analysis program. Cancer deaths from 2000 to 2021 were obtained from the Costa Rican National Institute of Statistics and Census. Age-standardised mortality rates were calculated using STATA®17. Findings YA comprised 10.7% of all invasive cancer cases diagnosed from 2006 to 2015. The age-standardized incidence rate (ASIR) of invasive cancer in YA was 50.9/100,000 person-years. The ASIR was twofold higher for females compared to males (IRR = 2.03, 95% CI:1.94, 2.13). This difference increased with age, peaking in the 35-39-year age group (IRR = 2.84, 95% CI:2.62, 3.10). Thyroid, breast, and cervical cancer were the most common in females. Testicular cancer was the most common in males. Leading causes of cancer-related deaths included cervical and breast cancer in females and stomach and brain/nervous system cancer in males. Interpretation The study highlights sex-specific patterns in cancer incidence and mortality among YA in Costa Rica to increase understanding and improve cancer outcomes in this age group. Funding This study was funded by the Intramural Research Program of the National Cancer Institute.

Abstract
BACKGROUND Active surveillance for prostate cancer was initiated in the early 2000s. We assessed the long-term outcomes of active surveillance in Japan. METHODS This multicenter prospective observational cohort study enrolled men aged 50-80 years with stage cT1cN0M0 prostate cancer in 2002 and 2003. The eligibility criteria included serum prostate-specific antigen level ≤ 20 ng/mL, ≤ 2 positive cores per 6-12 biopsy samples, Gleason score ≤ 6, and cancer involvement < 50% in the positive core. Patients were encouraged to undergo active surveillance. Prostate-specific antigen levels were measured bimonthly for 6 months and every 3 months thereafter. Triggers for recommending treatment were prostate-specific antigen doubling time of < 2 years and pathological progression on repeat biopsy. RESULTS Among 134 patients, 118 underwent active surveillance. The median age, prostate-specific antigen level at diagnosis, and maximum cancer occupancy were 70 years, 6.5 ng/mL, and 11.2%, respectively. Ninety-one patients had only one positive cancer core. The median observation period was 10.7 years. At 1 year, 65.7% underwent a repeat biopsy, and 37% of patients experienced pathological progression. The active surveillance continuation rates at 5, 10, and 15 years were 28%, 9%, and 4%, respectively. One prostate cancer-related death occurred in a patient who refused treatment despite pathological progression at the one-year repeat biopsy. CONCLUSION Active surveillance according to this study protocol was associated with conversion to the next treatment without delay, when indicated, despite the selection criteria and follow-up protocols being less rigorous than those recommended in current international guidelines.

Abstract
PURPOSE Breast cancer treatments are based on prognostic clinicopathologic features that form the basis for therapeutic guidelines. Although the utilization of these guidelines has decreased breast cancer-associated mortality rates over the past three decades, they are not adequate for individualized therapy. Radiation therapy (RT) is the backbone of breast cancer treatment. Although a highly successful therapeutic modality clinically, from a biological perspective, preclinical studies have shown RT to have the potential to alter tumor cell phenotype, immunogenicity, and the surrounding microenvironment, potentially changing the behavior of cancer cells and resulting in a significant variation in RT response. This review presents the recent advances in revealing the complex molecular changes induced by RT in the treatment of breast cancer and highlights the complexities of translating this information into clinically relevant tools for improved prognostic insights and the revelation of novel approaches for optimizing RT. METHODS AND MATERIALS Current literature was reviewed with a focus on recent advances made in the elucidation of tumor-associated radiation-induced molecular changes across molecular, genetic, and proteomic bases. This review was structured with the aim of providing an up-to-date overview over the very broad and complex subject matter of radiation-induced molecular changes and radioresistance, familiarizing the reader with the broader issue at hand. RESULTS The subject of radiation-induced molecular changes in breast cancer has been broached from various physiological focal points including that of the immune system, immunogenicity and the abscopal effect, tumor hypoxia, breast cancer classification and subtyping, molecular heterogeneity, and molecular plasticity. It is becoming increasingly apparent that breast cancer clinical subtyping alone does not adequately account for variation in RT response or radioresistance. Multiple components of the tumor microenvironment and immune system, delivered RT dose and fractionation schedules, radiation-induced bystander effects, and intrinsic tumor physiology and heterogeneity all contribute to the resultant RT outcome. CONCLUSIONS Despite recent advances and improvements in anticancer therapies, tumor resistance remains a significant challenge. As new analytical techniques and technologies continue to provide crucial insight into the complex molecular mechanisms of breast cancer and its treatment responses, it is becoming more evident that personalized anticancer treatment regimens may be vital in overcoming radioresistance.

Abstract
PURPOSE This study aims to investigate the psychological distress experienced by patients with an initial diagnosis of abnormal Pap smears or dysplastic changes of the cervix uteri. It investigated whether patients' age, education, information level and approach to information acquisition have an impact on their psychological distress. METHODS A total of 364 female patients, aged 20-80 years, referred to the special dysplasia consultation hour at the Department of Obstetrics and Gynecology, Wuerzburg, completed a questionnaire containing validated items to assess information level, information acquisition, information needs and psychological distress, including a distress thermometer. Data from questionnaires and medical reports were used for analysis. RESULTS The study found that 56.9% of patients experienced psychological distress before their first visit. Patients under 44 years of age, especially those with concerns about fertility and sexuality, and those with lower levels of education showed higher levels of distress (p-value = 0.018 and p-value = 0.037). 40.9% of patients felt poorly informed and 53.7% of patients wanted more information before their visit. Correlational analysis showed that the method of obtaining information correlated with the desire for more information (p-value < 0.001). Those who received information via the Internet felt less informed, wanted more information and experienced more anxiety. CONCLUSION These findings highlight the need for improved patient education strategies and effective doctor-patient communication to address the knowledge gap and reduce patient distress. In addition, healthcare providers should ensure that patients have access to reliable online resources for accurate information.

Abstract
Direct-acting antivirals ledipasvir (LDV) and daclatasvir (DCV) are widely used as part of combination therapies to treat Hepatitis C infections. Here we show that these compounds inhibit the proliferation, invasion, and colony formation of triple-negative MDA-MB-231 breast cancer cells, SRC-transduced SW620 colon cancer cells and SRC- transduced NIH3T3 fibroblasts. DCV also inhibits the expression of PDL-1, which is responsible for resistance to immunotherapy in breast cancer cells. The demonstrated low toxicity in many Hepatitis C patients suggests LDV and DCV could be used in combination therapies for cancer patients. At the molecular level, these direct-acting antivirals inhibit the phosphorylation of Akt and the ephrin type A receptor 2 (EPHA2) by destabilizing a Src-EPHA2 complex, although they do not affect the general kinase activity of Src. Thus, LDV and DCV could be effective drugs for Src-associated cancers without the inherent toxicity of classical Src inhibitors.

Abstract
Benzene is associated with diverse occupational and public health hazards. It exhibits an ability to rapidly permeate the skin and contaminate water and food sources, leading to dermal and ingestion exposures. Despite numerous studies examining the associations between benzene and various indicators of harm, the findings have yielded inconsistent results. Furthermore, relying solely on air concentration as a measure of benzene exposure is limited, as it fails to account for internal exposure dose and individual susceptibility. This study aimed to conduct a comprehensive review in order to present current knowledge on benzene biomarkers and their significance in evaluating exposure levels and associated health hazards. The search methodology adhered to the PRISMA guidelines and involved the application of specific inclusion and exclusion criteria across multiple databases including PubMed, Embase, and Web of Science. Two researchers independently extracted and evaluated the relevant data based on predetermined criteria. Following the screening process, a total of 80 articles were considered eligible out of the initially retrieved 1053 articles after undergoing screening and assessment for inclusion. As the level of exposure decreased, specific biomarkers demonstrated a gradual increase in limitations, including heightened background concentrations and vulnerability to confounding factors. The advancement of sampling and analysis techniques will yield new biomarkers. Additionally, when conducting practical work, it is crucial to employ a comprehensive utilization of diverse biomarkers while excluding individual metabolic variations and combined exposure factors.

Abstract
The in vitro cultures of Vachellia farnesiana (L) Wight & Arn. have demonstrated cytotoxic activity through callus extract on the HeLa cell line. Explants excised from in vitro-grown seedlings from seeds of two different locations were inoculated on Murashige and Skoog (MS) culture media containing various concentrations of N-6 benzyladenine (BA) or kinetin with 2,4-dichlorophenoxyacetic acid (2,4-D). Optimal efficiency in friable callus induction (100%) was achieved in leaf explants cultured on MS media containing 2.32 µM BA + 13.57 µM 2,4-D. Plant tissues (callus and leaf) were extracted and subjected to quantitative phytochemical analysis, revealing the highest total alkaloid and phenolic content in leaf extracts from Queretaro adult specimens (339.5 ± 20.9 mg atropine equivalents (AE) per g dry extract (DE) and 158.4 ± 12.5 mg gallic acid equivalents (GAE) per g DE, respectively). In contrast, callus cultures exhibited significantly higher total triterpene content (356-381 mg ursolic acid equivalents (UAE) per g DE) compared to leaf extracts (208-243 mg UAE/g DE). Both leaf and callus extracts displayed cytotoxic activity against the HeLa cell line, with a significantly lower half-maximal inhibitory concentration (IC50) for leaf extracts (28-32 µg/mL) compared to callus cultures (43-66 µg/mL), suggesting that alkaloids were primarily responsible for the cytotoxic activity. Furthermore, this study provides valuable insights into the controlled production of bioactive compounds with cytotoxic activity, with callus serving as a rich source.

Liu Y, Teng X, Yan Y, Zhao S, Wang G. Dexmedetomidine promotes necroptosis by upregulating PARP1 in non-small cell lung cancer. Biotechnol Genet Eng Rev 2024; 40:1281-1301. [PMID: 37066722 DOI: 10.1080/02648725.2023.2193469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 03/16/2023] [Indexed: 04/18/2023]
Abstract
The score and prognostic value of necroptosis were analyzed in the TCGA and GSE120622 datasets. Necroptosis has the highest correlation with the immune microenvironment, and the high score in NSCLC correlates with poor prognosis. Differentially expressed genes between non-small cell lung cancer (NSCLC) and controls in both datasets were identified and subjected to construct co-expression networks, respectively. Black and blue modules were selected because of high correction with necroptosis. The intersected two module genes were mainly involved in immune and inflammatory response, cell cycle process and DNA replication. Nine marker genes of necroptosis were identified in these modules and considered as candidate genes. Based on candidate genes, we identified two clusters utilizing concordance clustering, additionally dividing NSCLC samples into high- and low-risk groups. There were significant differences in overall survival between two clusters and between high- and low-risk groups. Furthermore, PARP1 was found among the candidate genes to be the target gene of dexmedetomidine acting on necroptosis. Molecular experimental results found that PARP1 was highly expressed in the dexmedetomidine treated NSCLC compared with the NSCLC. Candidate genes associated with necroptosis may provide a powerful prognostic tool for precision oncology. Dexmedetomidine may target PARP1 to promote necroptosis and then affect NSCLC.

Abstract
The liver is one of the most frequent sites of primary malignancies in humans. Hepatocellular carcinoma (HCC) is one of the most prevalent solid tumors with poor prognosis. Current treatments showed limited efficacy in some patients, and, therefore, alternative strategies, such as immunotherapy, cancer vaccines, adoptive cell therapy (ACT), and recently chimeric antigen receptors (CAR)-T cells, are developed to offer better efficacy and safety profile in patients with HCC. Unlike other ACTs like tumor-infiltrating lymphocytes (TILs), CAR-T cells are equipped with engineered CAR receptors that effectively identify tumor antigens and eliminate cancer cells without major histocompatibility complex (MHC) restriction. This process induces intracellular signaling, leading to T lymphocyte recruitment and subsequent activation of other effector cells in the tumor microenvironment (TME). Until today, novel approaches have been used to develop more potent CAR-T cells with robust persistence, specificity, trafficking, and safety. However, the clinical application of CAR-T cells in solid tumors is still challenging. Therefore, this study aims to review the advancement, prospects, and possible avenues of CAR-T cell application in HCC following an outline of the CAR structure and function.

Abstract
Introduction E-cigarettes and heated tobacco products (HTPs) are gaining worldwide significance. The tobacco industry is promoting these products as healthier alternatives to conventional cigarettes. Methods In this four-arm crossover study, we examined the acute effects of cigarette smoking, vaping IQOS, or vaping e-cigarettes (with or without nicotine) on hemodynamics, arterial stiffness, and small airways. Twenty subjects (10 male, 10 female), all occasional smokers, completed each study arm. There was at least a 48 h washout period before each test day. Arterial stiffness and peripheral and central hemodynamics were assessed using Mobil-O-Graph™ (I.E.M., Germany), whereas tremoFlo® c-100 (Thoracic Medical Systems Inc) was used to evaluate the effects on the small airways and resistance. Results Cigarettes, IQOS, e-cigarettes containing nicotine, and nicotine-free e-cigarettes had similar effects on peripheral and central hemodynamics as well as on arterial stiffness. We observed a significant increase in all parameters. However, only nicotine-containing products lead to increased bronchial obstruction, higher reactance, and a higher tidal volume. Conclusion Therefore, we concluded that cigarettes, IQOS, and e-cigarettes have similar effects on hemodynamics. No differences were observed between the nicotine-containing and nicotine-free e-cigarettes. All nicotine-containing products also influence small airways. These findings suggest that e-cigarettes and HTPs are not healthier alternatives than conventional cigarettes.

Abstract
Cancer is a subject of extensive investigation, and the utilization of omics technology has resulted in the generation of substantial volumes of big data in cancer research. Numerous databases are being developed to manage and organize this data effectively. These databases encompass various domains such as genomics, transcriptomics, proteomics, metabolomics, immunology, and drug discovery. The application of computational tools into various core components of pharmaceutical sciences constitutes "Pharmacoinformatics", an emerging paradigm in rational drug discovery. The three major features of pharmacoinformatics include (i) Structure modelling of putative drugs and targets, (ii) Compilation of databases and analysis using statistical approaches, and (iii) Employing artificial intelligence/machine learning algorithms for the discovery of novel therapeutic molecules. The development, updating, and analysis of databases using statistical approaches play a pivotal role in pharmacoinformatics. Multiple software tools are associated with oncoinformatics research. This review catalogs the databases and computational tools related to cancer drug discovery and highlights their potential implications in the pharmacoinformatics of cancer.

Abstract
Purpose Mammography is the gold standard screening technique for early detection of breast cancer. This study aimed to assess the knowledge of community pharmacists of different aspects emphasized by the JBCP programs. This study also identifies the attitudes and barriers towards promoting early detection services. Patients and Methods This study was a cross-sectional survey of community pharmacists in Jordan. Pharmacists were randomly selected and asked to complete an electronic questionnaire. Inclusion criteria: a pharmacist with a bachelor's degree or higher and registered at the JPA working in a community pharmacy. The questionnaire included demographic and socioeconomic information, knowledge, attitudes towards breast cancer screening mammography services, and barriers towards participation in the promotion of these services. Results A total of 1,088 community pharmacists were approached, 1,000 (91.8%) completed the questionnaire. Participants had an average age of 34 years ± 10.8 and average experience of 9.1 ± 9.5 years. Only 48 (37.8%) of the female pharmacists aged 40 years or older underwent a mammogram. Knowledge of symptoms of breast cancer was the highest with a score of 755, followed by knowledge of risk factors (670) and finally early detection of breast cancer (540). Many barriers were reported by the community pharmacists including lack of educational materials and time constraints. Pharmacists with higher educational levels (p<0.001), of female gender (p<0.001), attended continuous cancer-related education (p<0.001), encountered a higher percentage of female customers (p<0.001), in a certain geographic location (p=0.003), underwent mammography (p=0.014), and encountered high frequency of inquiries on mammogram by the customers (p<0.001) were all associated with higher knowledge scores. Conclusion Despite the reported barriers and insufficient knowledge in certain aspects of early detection of breast cancer, community pharmacists have positive attitudes and can be a valuable asset for awareness-raising efforts.

Abstract
Prostate cancer continues to be a prominent health concern for men globally. Current screening techniques, primarily the prostate-specific antigen (PSA) test and digital rectal examination (DRE), possess inherent limitations, with prostate biopsy being the definitive diagnostic procedure. The invasive nature of the biopsy and other drawbacks of current screening tests create the need for non-invasive and more accurate diagnostic methods. This study utilized 1H-NMR (Proton Nuclear Magnetic Resonance) based serum metabolomics to differentiate between prostate cancer (PCa) and benign prostatic hyperplasia (BPH). Serum samples from 40 PCa and 41 BPH patients were analysed using 1H-NMR spectroscopy. PepsNMR was utilized for preprocessing the raw NMR data, and the binned spectra were examined for patterns distinguishing PCa and BPH. Principal component analysis (PCA) showed a moderate separation between PCa and BPH, highlighting the distinct metabolic profiles of both conditions. A logistic regression model was then developed, which demonstrated good performance in distinguishing between the two conditions. The results showed significant variance in multiple metabolites between PCa and BPH, such as isovaleric acid, ethylmalonic acid, formate, and glutamic acid. This research underlines the potential of 1H-NMR-based serum metabolomics as a promising tool for improved prostate cancer screening, offering an alternative to the limitations of current screening methods.

Abstract
The increasing complexity and difficulty of surgical procedures have led to a rise in medical errors within clinical settings in recent years. Gastrointestinal diseases, in particular, present significant medical challenges and impose substantial economic burdens, underscoring the urgent need for experiential, high-fidelity gastrointestinal surgical training tools. This study leverages patient-specific computed tomography (CT) and magnetic resonance imaging (MRI) data, combined with 3D printed manufacturing, to develop hydrogel organ models with tunable performance and tissue-mimicking softness. These properties are achieved by regulating the freeze-thaw cycles, cross-linking agents, and the concentration of incorporated antibacterial nanoparticles in DN hydrogels. Through the application of indirect 3D printing and the "sacrificial material method", we successfully fabricate organ tissues such as the stomach, intestines, and blood vessels with high precision. In ex vivo surgical training demonstrations, these tissue-like soft hydrogels provide an effective platform for preoperative simulation and surgical training in digestive surgery, accommodating various surgical procedures and accurately simulating intraoperative bleeding. The development of advanced bionic organ models with specific and tunable characteristics based on DN hydrogels is poised to significantly advance surgical training, medical device testing, and the reform of medical education.

Abstract
A series of new gold(I) and silver(I) N-heterocyclic carbenes bearing a 1-thio-β-d-glucose tetraacetate moiety was synthesized and chemically characterized. The compounds' stability and solubility in physiological conditions were investigated employing a multitechnique approach. Interaction studies with biologically relevant proteins, such as superoxide dismutase (SOD) and human serum albumin (HSA), were conducted via UV-vis absorption spectroscopy and high-resolution ESI mass spectrometry. The biological activity of the compounds was evaluated in the A2780 and A2780R (cisplatin-resistant) ovarian cancer cell lines and the HSkMC (human skeletal muscle) healthy cell line. Inhibition studies of the selenoenzyme thioredoxin reductase (TrxR) were also carried out. The results highlighted that the gold complexes are more stable in aqueous environment and capable of interaction with SOD and HSA. Moreover, these carbenes strongly inhibited the TrxR activity. In contrast, the silver ones underwent structural alterations in the aqueous medium and showed greater antiproliferative activity.

Abstract
The incidence of invasive fungal infection (IFI) is increasing, especially among patients diagnosed with hematological malignancies due to their immunocompromised nature. Other risk factors include advanced age, exposure to immunosuppressants, neutropenia, and catheter use. Some of the most common IFI organisms reported are Candida and Aspergillus species, and other fungal species, including Scedosporium, Trichosporon, Cryptococcus, and Fusarium have also increasingly been reported in the past years. However, the epidemiologic data on IFI among patients with hematological malignancies in Asian countries are lacking. Therefore, we investigated published epidemiologic data on such cases from the past 10 years (2011-2021) and discuss the challenges faced in the diagnosis and management of IFIs in Asia.

Abstract
Particulate matter pollution (PMP) has been identified as a substantial contributor to cancer. However, accurately delineating the evolving trends in cancer burden attributable to PMP remains an ongoing challenge. The 1990-2019 disability-adjusted life years (DALYs) were used for cancers attributable to PMP from the Global Burden and Disease Study (GBD) 2019, including ambient particulate matter pollution (APMP) and household air pollution from solid fuels (HAP). The joinpoint regression and the Bayesian age-period-cohort (BAPC) model were employed to assess the corresponding trends over the periods 1990-2019 and 2020-2050, respectively. Additionally, statistical models such as frontier analysis and health inequality analysis were also utilized. During the 30-year period, cancer DALYs attributable to APMP increased globally, while those attributable to HAP and PMP decreased. Cancer DALYs attributable to APMP were positively correlated with socio-demographic index (SDI), while those attributable to PMP and HAP were negatively correlated with SDI. Frontier analysis identified the countries and regions requiring urgent action to mitigate PMP-attributable cancer. Finally, it was anticipated that the cancer burden attributable to APMP would increase during 2020 to 2050, while the burden attributable to HAP and PMP would decrease. This study conducted an epidemiological investigation of the burden of cancer attributable to APMP, HAP and PMP in various regions and populations worldwide, providing epidemiological insights into the global burden of cancer attributable to PMP and guiding policy and research directions.

Abstract
Graphene is the newest form of elemental carbon and it is becoming rapidly a potential candidate in the framework of nano-bio research. Many reports confirm the successful use of graphene-based materials as carriers of anticancer drugs having relatively high loading capacities compared with other nanocarriers. Here, the outcomes of a systematic study of the adsorption behavior of FDA approved PtII drugs cisplatin, oxaliplatin, and carboplatin on surface models of pristine, holey, and nitrogen-doped holey graphene are reported. DFT investigations in water solvent have been carried out considering several initial orientations of the drugs with respect to the surfaces. Adsorption free energies, calculated including basis set superposition error (BSSE) corrections, result to be significantly negative for many of the drug@carrier adducts indicating that tested layers could be used as potential carriers for the delivery of anticancer PtII drugs. The reduced density gradient (RDG) analysis allows to show that many kinds of non-covalent interactions, including canonical H-bond, are responsible for the stabilization of the formed adducts.

Abstract
BACKGROUND Thyroid cancer (TC) is the most common malignancy of the endocrine system. This study aimed to assess the global distribution of TC incidence and mortality in 2022, as well as to predict the burden for the year 2050. METHODS Data from the GLOBOCAN 2022 database were used to analyze the age-standardized incidence and mortality rates of TC by sex, age group (<55 years and ≥55 years), country, world region, and level of Human Development Index (HDI) for 185 countries. The predicted incidence and mortality burden for 2050 was calculated based on demographic projections. RESULTS In 2022, an estimated 821,214 new TC cases and 47,507 TC-related deaths occurred worldwide. The age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs) were higher in women (ASIR: 13.60 per 100,000; ASMR: 0.53 per 100,000) than in men (ASIR: 4.60 per 100,000; ASMR: 0.35 per 100,000). The ASIR in high HDI countries was approximately ten times higher than that in low HDI countries for both sexes, with relatively similar ASMR across regions. Among 185 countries, China had the largest number of TC cases (accounting for 56.77% of total cases) and TC-related deaths (accounting for 24.35% of global TC-related deaths), with the highest ASIR in men (13.30 per 100,000). Worldwide, approximately 64.63% of TC cases occurred in populations under 55 years old, while nearly 82.99% of TC-related deaths occurred in populations aged 55 years and above. If the rates stay the same as in 2022, it is projected that approximately 1,100,000 new TC cases and 91,000 TC-related deaths will occur in 2050, indicating a 34.15% and 89.58% increase, respectively. CONCLUSIONS TC is a highly frequent cancer worldwide with disparities across regions, genders, and age groups. Our results provide light on the worldwide TC disease burden and facilitate regionally customized prevention measures.

Abstract
Breast cancer (BC) has different molecular subgroups related to different risks and treatments. Tumor biopsies for BC detection are invasive and may not reflect tumor heterogeneity. Liquid biopsies have become relevant because they might overcome these limitations. We rationalize that liquid cfDNA biopsies through shallow whole genome sequencing (sWGS) could improve the detection of tumor alterations, complementing the genomic profiling. We evaluated the feasibility to detect somatic copy number alterations (SCNAs) in BC using shallow whole genome sequencing (sWGS) in cfDNA from archived samples from National Cancer Institute of Colombia patients. We sequenced tumor tissues from 38 BC patients with different molecular subtypes using a gene panel of 176 genes significantly mutated in cancer, and by liquid biopsies using sWGS on 20 paired samples to detect SCNAs and compare with the tumor samples. We identified an extensive intertumoral heterogeneity between the molecular subtypes of BC, with a mean tumor load of 602 mutations in the gene panel of tumor tissues. There was a 12.3% of concordance in deletions in the cfDNA-tumor pairs considering only the genes covered by the panel encompassing seven genes: BRCA1, CDK12, NF1, MAP2K4, NCOR1, TP53, and KEAP1 in three patients. This study shows the feasibility to complement the genomic analysis of tumor tissue biopsies to detect SCNA in BC using sWGS in cfDNA, providing a wider identification of potential therapeutic targets.

Abstract
Although recent advancements in cancer immunology have resulted in the approval of numerous immunotherapies, minimal progress has been observed in addressing hard-to-treat cancers. In this context, therapeutic oligonucleotides, including interfering RNAs, antisense oligonucleotides, aptamers, and DNAzymes, have gained a central role in cancer therapeutic approaches due to their capacity to regulate gene expression and protein function with reduced toxicity compared with conventional chemotherapeutics. Nevertheless, systemic administration of naked oligonucleotides faces many extra- and intracellular challenges that can be overcome by using effective delivery systems. Thus, viral and non-viral carriers can improve oligonucleotide stability and intracellular uptake, enhance tumor accumulation, and increase the probability of endosomal escape while minimizing other adverse effects. Therefore, gaining more insight into fundamental mechanisms of actions of various oligonucleotides and the challenges posed by naked oligonucleotide administration, this article provides a comprehensive review of the recent progress on oligonucleotide delivery systems and an overview of completed and ongoing cancer clinical trials that can shape future oncological treatments.

Abstract
A facile, green, one-pot multicomponent synthesis strategy was employed to fabricate novel thiazole scaffolds incorporating phthalazine, pyridazine, and pyrido-pyridazine derivatives (4a-4o). This synthetic route entailed the reaction of an α-halo carbonyl compound (1) with thiosemicarbazide (2) and various anhydrides (3a-3o), utilizing NiFe2O4 nanoparticles as a reusable catalyst in an ethanol:water (1:1) solvent system. The cytotoxicity of the synthesized compounds was meticulously assessed against three cancer cell lines, A375, HeLa, and MCF-7, employing IC50 values (μM) as the benchmark, and compared to the reference drug erlotinib. Compound 4n displayed remarkable efficacy against A375 (0.87 ± 0.31 μM), HeLa (1.38 ± 1.24 μM), and MCF-7 (1.13 ± 0.96 μM) cell lines, significantly surpassing erlotinib's IC50 values. Additionally, compounds 4k, 4l, 4m, and 4o demonstrated notable cytotoxicity across all tested cell lines, indicating their potential as effective anticancer agents. In silico docking studies against Hsp82 and Hsp90 proteins indicated that ligands 4k, 4m, 4c, 4j, 4o, and 4l had superior binding affinities compared to erlotinib. ADME analysis showed that compounds 4n, 4j, 4l, 4m, and 4o had favorable pharmacokinetic profiles, including nontoxicity, high human intestinal absorption, and low CYP inhibitory promiscuity. Structure-activity relationship analysis revealed that cyano and benzylidene substitutions significantly enhanced anticancer activity. Overall, the synthesized compounds, particularly 4n, demonstrated high efficacy, favorable binding interactions, and promising pharmacokinetic profiles, making them strong candidates for further development as anticancer agents.

Abstract
Breast cancer, the most common cancer diagnosed among women, disproportionately affects low- and middle-income countries (LMICs). Based on an ethnographic study conducted in Central Vietnam in 2019, including observation and interviews with 33 women patients, we investigate how women and their families managed the financial burden of breast cancer care. Our findings suggest that in a context where health-related risk protection is poorly organised and out-of-pocket expenses are burdensome, despite the presence of universal health coverage, patients must rely heavily on informal arrangements to finance their treatment. They proactively researched available information and undertook extensive and ramified work to prove their deservingness for some types of assistance, including strategically disclosing their cancer status or using tactics to accelerate the process of applying for state welfare. Affected families must make hard calculations to prioritise the pressing health need of a member diagnosed with cancer and in many circumstances, forfeited the education of their young children. We offer theoretical understanding of 'patient work' beyond the routine management of the biological aspects of an illness. In addition, we demonstrate how engaging in those various coping practices can reinforce one's vulnerability to a vicious cycle of illness and poverty and amplify socio-economic inequalities among the affected community and the larger society. We argue this situation, if not tackled urgently and appropriately, can impede the progress towards achieving Sustainable Development Goal 3 (Good Health and Wellbeing) and Goal 10 (Reduced Inequalities) in LMICs amidst the non-communicable disease epidemic.

Abstract
Lung cancer remains a global health concern, demanding the development of noninvasive, prompt, selective, and point-of-care diagnostic tools. Correspondingly, breath analysis using nanobiosensors has emerged as a promising noninvasive nose-on-chip technique for the early detection of lung cancer through monitoring diversified biomarkers such as volatile organic compounds/gases in exhaled breath. This comprehensive review summarizes the state-of-the-art breath-based lung cancer diagnosis employing chemiresistive-module nanobiosensors supported by theoretical findings. It unveils the fundamental mechanisms and biological basis of breath biomarker generation associated with lung cancer, technological advancements, and clinical implementation of nanobiosensor-based breath analysis. It explores the merits, challenges, and potential alternate solutions in implementing these nanobiosensors in clinical settings, including standardization, biocompatibility/toxicity analysis, green and sustainable technologies, life-cycle assessment, and scheming regulatory modalities. It highlights nanobiosensors' role in facilitating precise, real-time, and on-site detection of lung cancer through breath analysis, leading to improved patient outcomes, enhanced clinical management, and remote personalized monitoring. Additionally, integrating these biosensors with artificial intelligence, machine learning, Internet-of-things, bioinformatics, and omics technologies is discussed, providing insights into the prospects of intelligent nose-on-chip lung cancer sniffing nanobiosensors. Overall, this review consolidates knowledge on breathomic biosensor-based lung cancer screening, shedding light on its significance and potential applications in advancing state-of-the-art medical diagnostics to reduce the burden on hospitals and save human lives.

Abstract
In most developed countries, both organized screening (OrgS) and opportunistic screening (OppS) coexist. The literature has extensively covered the impact of organized screening on women's survival after breast cancer. However, the impact of opportunistic screening has been less frequently described due to the challenge of identifying the target population. The aim of this study was to describe the net survival and excess mortality hazard (EMH) in each screening group (OrgS, OppS, or No screening) and to determine whether there is an identical social gradient in each groups. Three data sources (cancer registry, screening coordination centers, and National Health Data System [NHDS]) were used to identify the three screening groups. The European Deprivation Index (EDI) defined the level of deprivation. We modeled excess breast cancer mortality hazard and net survival using penalized flexible models. We observed a higher EMH for "No screening" women compared with the other two groups, regardless of level of deprivation and age at diagnosis. A social gradient appeared for each group at different follow-up times and particularly between 2 and 3 years of follow-up for "OrgS" and "OppS" women. Net survival was higher for "OrgS" women than "OppS" women, especially for the oldest women, and regardless of the deprivation level. This study provides new evidence of the impact of OrgS on net survival and excess mortality hazard after breast cancer, compared with opportunistic screening or no screening, and tends to show that OrgS attenuates the social gradient effect.

Abstract
The importance of the complex interplay between the microbiome and mucosal immunity, particularly within the respiratory tract, has gained significant attention due to its potential implications for the severity and progression of lung diseases. Therefore, this review summarizes the specific interactions through which the respiratory tract-specific microbiome influences mucosal immunity and ultimately impacts respiratory health. Furthermore, we discuss how the microbiome affects mucosal immunity, considering tissue-specific variations, and its capacity in respiratory diseases containing asthma, chronic obstructive pulmonary disease, and lung cancer. Additionally, we investigate the external factors which affect the relationship between respiratory microbiome and mucosal immune responses. By exploring these intricate interactions, this review provides valuable insights into the potential for microbiome-based interventions to modulate mucosal immunity and alleviate the severity of respiratory diseases.

Abstract
Multi-aptamer recognition of breast cancer cells (MCF-7) is utilized to achieve high specificity. The method comprises two parts, aptamer-functionalized mesoporous silica nanoparticles (MSNs) loaded with dissimilar dyes (thymolphthalein or curcumin) as signal transducers and aptamer-modified magnetic beads (MBs) as capture agents, which worked together to detect MCF-7 cells sensitively and accurately. The results indicated that the aptasensor has a linear detection range of 100 to 4000 cells and a detection threshold of 10 cells/mL. The method had been successfully employed to detect breast cancer cells in real blood samples to distinguish between breast cancer patients and healthy individuals. In conclusion, the development of the multi-aptamer-based colorimetric sensor offered a novel method for the highly selective detection of MCF-7 cells, contributing to the accurate identification of breast cancer.

[PMID: 39237932 PMCID: PMC11378503 DOI: 10.1186/s12885-024-12862-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Accepted: 08/27/2024] [Indexed: 09/07/2024] Open
Abstract
BACKGROUND Patients with head and neck cancers (HNC) experience many transitions in care (TiC), occurring when patients are transferred between healthcare providers and/or settings. TiC can compromise patient safety, decrease patient satisfaction, and increase healthcare costs. The evidence around TiC among patients with HNC is sparse. The objective of this study was to improve our understanding of TiC among patients with HNC to identify ways to improve care. METHODS This multimethod study consisted of two phases: Phase I (retrospective population-based cohort study) characterized the number and type of TiC that patients with HNC experienced using deterministically linked, population-based administrative health data in Alberta, Canada (January 1, 2012, to September 1, 2020), and Phase II (qualitative descriptive study) used semi-structured interviews to explore the lived experiences of patients with HNC and their healthcare providers during TiC. RESULTS There were 3,752 patients with HNC; most were male (70.8%) with a mean age at diagnosis of 63.3 years (SD 13.1). Patients underwent an average of 1.6 (SD 0.7) treatments, commonly transitioning from surgery to radiotherapy (21.2%). Many patients with HNC were admitted to the hospital during the study period, averaging 3.3 (SD 3.0) hospital admissions and 7.8 (SD 12.6) emergency department visits per patient over the study period. Visits to healthcare providers were also frequent, with the highest number of physician visits being to general practitioners (average = 70.51 per patient). Analysis of sixteen semi-structured interviews (ten patients with HNC and six healthcare providers) revealed three themes: (1) Navigating the healthcare system including challenges with the complexity of HNC care amongst healthcare system pressures, (2) Relational head and neck cancer care which encompasses patient expectations and relationships, and (3) System and individual impact of transitions in care. CONCLUSIONS This study identified challenges faced by both patients with HNC and their healthcare providers amidst the frequent TiC within cancer care, which was perceived to have an impact on quality of care. These findings provide crucial insights that can inform and guide future research or the development of health interventions aiming to improve the quality of TiC within this patient population.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) remains one of the most prevalent malignant tumors, exhibiting a high morbidity and mortality rate. The mechanism of its occurrence and development requires further study. The objective of this study was to investigate the role of SERPINA12 in the diagnosis, prognosis prediction and biological function within HCC. METHODS The Cancer Genome Atlas (TCGA) data were employed to analyze the relationship between clinical features and SERPINA12 expression in HCC. Kaplan-Meier curves were utilized to analyze the correlation between SERPINA12 expression and prognosis in HCC. The function of SERPINA12 was determined by enrichment analysis, and the relationship between SERPINA12 expression and immune cell infiltration was investigated. The expression of SERPINA12 was examined in 75 patients with HCC using RT-qPCR and immunohistochemistry, and survival analysis was performed. RESULTS The expression of SERPINA12 from TCGA database was found to be significantly higher in HCC tissues than in normal tissues and carried a poor prognosis. ROC curve demonstrated the diagnostic potential of SERPINA12 for HCC. The multivariate Cox regression analysis showed that pathologic T stage, tumor status, and SERPINA12 expression were independently associated with patient survival. The SERPINA12 expression was found to correlate with immune cell infiltration. Our RT-qPCR and immunohistochemical analysis revealed high expression of SERPINA12 in tumor tissues. Survival analysis indicated its association with poor prognosis. CONCLUSION SERPINA12 is a promising biomarker for diagnosis and prognosis, and it is associated with immune cell infiltration.

Exploring Radioiodinated Anastrozole and Epirubicin as AKT1-Targeted Radiopharmaceuticals in Breast Cancer: In Silico Analysis and Potential Therapeutic Effect with Functional Nuclear Imagining Implications. Molecules 2024; 29:4203. [PMID: 39275052 PMCID: PMC11397058 DOI: 10.3390/molecules29174203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2024] [Revised: 08/29/2024] [Accepted: 09/03/2024] [Indexed: 09/16/2024] Open
Abstract
This study evaluates radio-iodinated anastrozole ([125I]anastrozole) and epirubicin ([125I]epirubicin) for AKT1-targeted breast cancer therapy, utilizing radiopharmaceutical therapy (RPT) for personalized treatment. Through molecular docking and dynamics simulations (200 ns), it investigates these compounds' binding affinities and mechanisms to the AKT1 enzyme, compared to the co-crystallized ligand, a known AKT1 inhibitor. Molecular docking results show that [125I]epirubicin has the highest ΔGbind (-11.84 kcal/mol), indicating a superior binding affinity compared to [125I] anastrozole (-10.68 kcal/mol) and the co-crystallized ligand (-9.53 kcal/mol). Molecular dynamics (MD) simulations confirmed a stable interaction with the AKT1 enzyme, with [125I]anastrozole and [125I]epirubicin reaching stability after approximately 68 ns with an average RMSD of around 2.2 Å, while the co-crystallized ligand stabilized at approximately 2.69 Å after 87 ns. RMSF analysis showed no significant shifts in residues or segments, with consistent patterns and differences of less than 2 Å, maintaining enzyme stability. The [125I]epirubicin complex maintained an average of four H-bonds, indicating strong and stable interactions, while [125I]anastrozole consistently formed three H-bonds. The average Rg values for both complexes were ~16.8 ± 0.1 Å, indicating no significant changes in the enzyme's compactness, thus preserving structural integrity. These analyses reveal stable binding and minimal structural perturbations, suggesting the high potential for AKT1 inhibition. MM-PBSA calculations confirm the potential of these radio-iodinated compounds as AKT1 inhibitors, with [125I]epirubicin exhibiting the most favorable binding energy (-23.57 ± 0.14 kcal/mol) compared to [125I]anastrozole (-20.03 ± 0.15 kcal/mol) and the co-crystallized ligand (-16.38 ± 0.14 kcal/mol), highlighting the significant role of electrostatic interactions in stabilizing the complex. The computational analysis shows [125I]anastrozole and [125I]epirubicin may play promising roles as AKT1 inhibitors, especially [125I]epirubicin for its high binding affinity and dynamic receptor interactions. These findings, supported by molecular docking scores and MM-PBSA binding energies, advocate for their potential superior inhibitory capability against the AKT1 enzyme. Nevertheless, it is crucial to validate these computational predictions through in vitro and in vivo studies to thoroughly evaluate the therapeutic potential and viability of these compounds for AKT1-targeted breast cancer treatment.

Abstract
Background Gastrointestinal tumors represent a significant component of the cancer burden in Asia. This study aims to evaluate the burden of gastrointestinal tumors in Asia from 1990 to 2021 using data from the Global Burden of Disease Study 2021 (GBD 2021). Methods The absolute incidence, mortality, and disability adjusted life years (DALYs) number and rate of six gastrointestinal tumors(colon and rectum cancer (CRC), stomach cancer (SC), pancreatic cancer (PC), esophageal cancer (EC), liver cancer (LC) and gallbladder and biliary tract cancer (GBTC)) in 48 Asian countries were extracted from GBD 2021. Differences were analyzed based on gender, age, year, location and socio-demographic index (SDI). Results In 2021, SC accounted for the highest disease burden in Asia (DALYs=16.41million [95% UI: 13.70, 19.62]). From 1990 to 2021, the age-standardized incidence rates of EC, LC, and SC in Asia declined, while the incidence rates of CRC and PC increased significantly, with CRC showing the largest rise (AAPC=1.08 [95% CI: 1.02 to 1.12]). Gastrointestinal tumors DALY rates peaked at age 70 and above, with males generally exhibiting higher rates than females. Furthermore, East Asia bears a higher burden compared to other Asian subregions. A higher SDI correlates with increased DALY rates for PC, but no linear relationship was observed for other gastrointestinal tumors. Conclusion The burden of gastrointestinal tumors in Asia remains high and may continue to increase. Therefore, effective prevention and treatment measures are essential to address the challenge posed by gastrointestinal tumors.

Abstract
NF-κB is a promising target for cancer treatment because of its overactivation in almost all cancers but countless NF-κB inhibitors rarely became clinical drugs due to side effects. In contrast to traditional cancer treatments aimed at inhibiting NF-κB activity, this study develop a novel approach termed HOPE, which focuses on activating the exogenous effector gene CRISPR-Cas13a within cancer cells, achieved by utilizing the NF-κB-specific promoter DMP previously constructed, then targets and suppresses the expression of oncogenes TERT, PLK1, KRAS and MYC at mRNA level. We evaluated the antitumour effects of HOPE in various cultured cells and confirmed it could induce obvious the death of cancer cells without affecting normal cells. By packaging HOPE into adeno-associated virus (AAV) and intravenously injected it to treat mice that were subcutaneously transplanted with colorectal cancer. This validated that rAAV-HOPE could significantly inhibit tumour growth without side effects. Based on the scRNA-seq data, we observed that HOPE could activate the immune system and decrease the proportion of cancer cells, particularly reducing the stemness of cancer cells. This study elucidates an important role of HOPE in inhibiting cancer cell growth both in vitro and in vivo, additionally provides a novel therapeutic technology for cancer gene therapy.

Abstract
PURPOSE High throughput technologies have identified molecular patterns in colorectal cancer (CRC) cells, aiding in modeling responses to anti-cancer treatments. The different responses observed depend on the type of cancer, the tumour grade and the functional programme of the cancer cells. Recent studies suggest that the unfolded protein response (UPR), autophagy and apoptosis could be involved in treatment resistance mechanisms by interacting with the tumour microenvironment (TME). EXPERIMENTAL DESIGN We analysed by LC-MS/MS the proteome of two representative colon adenocarcinoma epithelial cell lines from different tumour grades (CCL-233 and CCL-221) at the basal state or after the UPR induction. RESULTS Cell lines expressed a different proteome on about 10% of their total proteins identified, especially on UPR, autophagy and apoptosis pathways proteins at basal state. After UPR induction, the proteome of the cells was modified with a greater adaptive response to cellular stress in CCL-221 cells where the UPR was strongly activated at the basal state. CONCLUSIONS AND CLINICAL RELEVANCE CRC cell lines at different tumour grades expressed different functional programmes at the proteomic level and were characterised by different responses to the UPR induction. This study suggests that baseline cancer cell stress status could have an impact on the efficiency of cancer therapies.

Abstract
BACKGROUND Breast cancer, with its high morbidity and mortality rates, is a significant global health burden. Traditional treatments-surgery, chemotherapy, and radiotherapy-are widely used but come with drawbacks such as recurrence, metastasis, and significant side effects, including damage to healthy tissues. To address these limitations, new therapeutic strategies are being developed. Peroxidases (POD) can catalyze excess H2O2 in the tumor microenvironment to generate reactive oxygen species (ROS), which induce cancer cell apoptosis by disrupting redox homeostasis and modulating apoptosis-related proteins. However, natural enzymes face challenges like poor stability, high cost, and sensitivity to environmental conditions, limiting their application in breast cancer treatment. Nanozymes, nanomaterials with enzyme-like activity, offer a promising alternative by overcoming these limitations. METHODS In this study, we successfully prepared Au@Pd nanozymes with peroxidase activity by depositing metallic Pd on Au nanoparticles (Au NPs) synthesized using a trisodium citrate reduction method and ascorbic acid reduction. The in vitro validation was conducted through a series of experiments, including ROS detection, flow cytometry, CCK-8 assay, DNA damage assessment, live/dead cell staining, Western blot (WB), and qPCR. Tumor treatment was performed via tail vein injection of the drug, followed by HE staining of the treated tissues and biochemical analysis of the blood. RESULTS Au@Pd nanozymes can effectively accumulate at the tumor site through the EPR effect and exert peroxidase-like activity, catalyzing the excess H2O2 in the tumor microenvironment to produce ROS. This triggers apoptosis pathways and DNA damage, leading to the downregulation of the anti-apoptotic protein Bcl-2, upregulation of the pro-apoptotic protein Bax, and induction of apoptosis-related genes, demonstrating strong anti-tumor effects. CONCLUSIONS This study developed an efficient nanozyme-mediated catalytic therapy strategy targeting the tumor microenvironment for the treatment of breast cancer cells.

Abstract
Cancer research has advanced tremendously with the identification of causative genes, proteins, and signaling pathways. Numerous antitumor drugs have been designed and screened for cancer therapeutics; however, designing target-specific drugs for malignant cells with minimal side effects is challenging. Recently, energy-sensing- and homeostasis-associated molecules and signaling pathways playing a role in proliferation, apoptosis, autophagy, and angiogenesis have received increasing attention. Energy-metabolism-based studies have shown the contribution of energetics to cancer development, where tumor cells show increased glycolytic activity and decreased oxidative phosphorylation (the Warburg effect) in order to obtain the required additional energy for rapid division. The role of energy homeostasis in the survival of normal as well as malignant cells is critical; therefore, fuel intake and expenditure must be balanced within acceptable limits. Thus, energy-sensing enzymes detecting the disruption of glycolysis, AMP, ATP, or GTP levels are promising anticancer therapeutic targets. Here, we review the common energy mediators and energy sensors and their metabolic properties, mechanisms, and associated signaling pathways involved in carcinogenesis, and explore the possibility of identifying drugs for inhibiting the energy metabolism of tumor cells. Furthermore, to corroborate our hypothesis, we performed meta-analysis based on transcriptomic profiling to search for energy-associated biomarkers and canonical pathways.

Derivation of human primary prostate epithelial cell lines by differentially targeting the CDKN2A locus along with expression of hTERT. Sci Rep 2024; 14:20409. [PMID: 39223207 PMCID: PMC11369182 DOI: 10.1038/s41598-024-71306-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Accepted: 08/27/2024] [Indexed: 09/04/2024] Open
Abstract
Prostate cancer (PCa) is the most common cancer diagnosed in men worldwide and was the second leading cause of cancer-related deaths in US males in 2022. Prostate cancer also represents the second highest cancer mortality disparity between non-Hispanic blacks and whites. However, there is a relatively small number of prostate normal and cancer cell lines compared to other cancers. To identify the molecular basis of PCa progression, it is important to have prostate epithelial cell (PrEC) lines as karyotypically normal as possible. Our lab recently developed a novel methodology for the rapid and efficient immortalization of normal human PrEC that combines simultaneous CRISPR-directed inactivation of CDKN2A exon 2 (which directs expression of p16INK4A and p14ARF) and ectopic expression of an hTERT transgene. To optimize this methodology to generate immortalized lines with minimal genetic alterations, we sought to target exon 1α of the CDKN2A locus so that p16INK4A expression is ablated while the exons encoding p14ARF remains unaltered. Here we describe the establishment of two cell lines: one with the above-mentioned p16INK4A only loss, and a second line targeting both products in the CDKN2A locus. We characterize the potential lineage origin of these new cell lines along with our previously obtained clones, revealing distinct gene expression signatures. Based on the analyses of protein markers and RNA expression signatures, these cell lines are most closely related to a subpopulation of basal prostatic cells. Given the simplicity of this one-step methodology and the fact that it uses only the minimal genetic alterations necessary for immortalization, it should also be suitable for the establishment of cell lines from primary prostate tumor samples, an urgent need given the limited number of available prostate cancer cell lines.
