Abstract
BACKGROUND This study aims to explore how miR-98-5p affects osteoarthritis, focusing on its role in chondrocyte inflammation, apoptosis, and extracellular matrix (ECM) degradation. METHODS Quantitative real-time PCR was used to measure miR-98-5p and CASP3 mRNA levels in OA cartilage tissues and IL-1β-treated CHON-001 cells. We predicted miR-98-5p and CASP3 binding sites using TargetScan and confirmed them via luciferase reporter assays. Chondrocyte viability was analyzed using CCK-8 assays, while pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) were quantified via ELISA. Caspase-3 activity was examined to assess apoptosis, and Western blotting was conducted for protein marker quantification. RESULTS Our results showed lower miR-98-5p levels in both OA cartilage and IL-1β-stimulated cells. Increasing miR-98-5p resulted in reduced pro-inflammatory cytokines, decreased caspase-3 activity, and improved cell viability. Furthermore, miR-98-5p overexpression hindered IL-1β-induced ECM degradation, evident from the decline in MMP-13 and β-catenin levels, and an increase in COL2A1 expression. MiR-98-5p's impact on CASP3 mRNA directly influenced its expression. Mimicking miR-98-5p's effects, CASP3 knockdown also inhibited IL-1β-induced inflammation, apoptosis, and ECM degradation. In contrast, CASP3 overexpression negated the suppressive effects of miR-98-5p. CONCLUSIONS In conclusion, our data collectively suggest that miR-98-5p plays a protective role against IL-1β-induced damage in chondrocytes by targeting CASP3, highlighting its potential as a therapeutic target for OA.

Abstract
The use of herbal medicine as an adjuvant therapy in the management of gastric cancer has yielded encouraging outcomes, notably in enhancing overall survival rates and extending periods of disease remission. Additionally, herbal medicines have demonstrated potential anti-metastatic effects in gastric cancer. Despite these promising findings, there remains a significant gap in our understanding regarding the precise pharmacological mechanisms, the identification of specific herbal compounds, and their safety and efficacy profiles in the context of gastric cancer therapy. In addressing this knowledge deficit, the present study proposes a comprehensive exploratory analysis of the Tiao-Yuan-Tong-Wei decoction (TYTW), utilizing an integrative approach combining system pharmacology and molecular docking techniques. This investigation aims to elucidate the pharmacological actions of TYTW in gastric pathologies. It is hypothesized that the therapeutic efficacy of TYTW in counteracting gastric diseases stems from its ability to modulate key signaling pathways, thereby influencing PIK3CA activity and exerting anti-inflammatory effects. This modulation is observed predominantly in pathways such as PI3K/AKT, MAPK, and those directly associated with gastric cancer. Furthermore, the study explores how TYTW's metabolites (agrimoniin, baicalin, corosolic acid, and luteolin) interact with molecular targets like AKT1, CASP3, ESR1, IL6, PIK3CA, and PTGS2, and their subsequent impact on these critical pathways and biological processes. Therefore, this study represents preliminary research on the anticancer molecular mechanism of TYTW by performing network pharmacology and providing theoretical evidence for further experimental investigations.

Abstract
Prior evidence has suggested the alleviatory effect of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on neuroinflammation in neurodegenerative diseases. This study primarily investigates the underlying mechanism of how the long non-coding RNA MALAT1 affects neuronal apoptosis in the hippocampus of mice with autism spectrum disorder (ASD). The findings demonstrate that CASP3 is highly expressed while MALAT1 is downregulated in the hippocampal neurons of autistic mice. MALAT1 mainly localizes within the cell nucleus and recruits DNA methyltransferases (including DNMT1, DNMT3a, and DNMT3b) to the promoter region of CASP3, promoting its methylation and further inhibiting its expression. In vitro experiments reveal that reducing MALAT1 expression promotes the expression of CASP3 and Bax while suppressing Bcl-2 expression, thereby enhancing cellular apoptosis. Conversely, increasing MALAT1 expression yields the opposite effect. Consequently, these results further confirm the role of MALAT1 in suppressing neuronal apoptosis in the hippocampus of mice with ASD through the regulation of CASP3 promoter methylation. Thus, this research unveils the significant roles of MALAT1 and CASP3 in the pathogenesis of ASD, offering new possibilities for future therapeutic interventions.

Abstract
Coronavirus disease (COVID-19) and its outcomes remain one of the most challenging problems today. COVID-19 in children could be asymptomatic, but can result in a fatal outcome; therefore, predictions of the disease severity are important. The goal was to investigate the human genetic factors that could be associated with COVID-19 severity in children. Single-nucleotide polymorphisms of the following genes were studied: ACE2 (rs2074192), IFNAR2 (rs2236757), TYK2 (rs2304256), OAS1 (rs10774671), OAS3 (rs10735079), CD40 (rs4813003), FCGR2A (rs1801274) and CASP3 (rs113420705). In the case-control study were 30 children with mild or moderate course of the disease; 30 with severe COVID-19 symptoms and multisystem inflammatory syndrome in children (MIS-C) and 15 who were healthy, and who did not have SARS-CoV-2 (PCR negative, Ig G negative). The study revealed that ACE2 rs2074192 (allele T), IFNAR2 rs2236757 (allele A), OAS1 rs10774671 (allele A), CD40 rs4813003 (allele C), CASP3 rs113420705 (allele C) and male sex contribute to severe COVID-19 course and MIS-C in 85.6% of cases. The World Health Organization reported that new SARS-CoV-2 variants may cause previously unseen symptoms in children. Although the study has limitations due to cohort size, the findings can help provide a better understanding of SARS-CoV-2 infection and proactive pediatric patient management.

Abstract
BACKGROUND Non-alcohol fatty liver disease (NAFLD) is the most prevalent hepatopathy in China, with few effective cures currently. This work aimed to confirm the effect of DHM in vivo/vitro and explore the potential mechanism based on a network pharmacology-based approach. METHODS The rats were fed using a high-fat diet (HFD) to accumulate lipid. DHM at different concentrations was used to treat the HFD rats. The serum total cholesterol (TC), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected using ELISA kits. The target genes of DHM against NAFLD were screened by online databases. Then, the cytotoxicity of DHM in primary hepatocytes and HepG2 cells was determined by MTT reagent. qRT-PCR was used to quantify the expression level of PPAGR and CASP3 mRNA. Cell apoptosis and intracellular triglyceride (TG) were detected. RESULTS HFD diet increased rat liver weight/body weight ratio, serum TC, ALT, and AST. But DHM treatment can reduce these elevated indicators. DHM targeted 14 potential genes in NAFLD. PPARG and CASP3 were two hub genes for DHM against NAFLD, with score factor coefficients of -7.1 and -6.8 kcal/mol. DHM reduced the increased PPARG mRNA level and intracellular TG induced by palmitic acid. DHM can reduce the increased CASP3 mRNA level and cell apoptosis induced by palmitic acid. CONCLUSION This work demonstrates a mechanism of DHM that alleviates lipid metabolism disorder and cell apoptosis for the treatment of NAFLD, evidencing the potential application of DHM in NAFLD.

Abstract
Breast cancer (BC) is the type of neoplasm that most affects women worldwide. It is known that one of the hallmarks of cancer is the resistance to cell death with the evasion of apoptosis. Considering the relevance of TP53, BCL2, CASP3, and CASP9 genes for the occurrence of the intrinsic apoptosis, this study investigated the distribution of the genetic variants rs17880560 (TP53), rs11269260 (BCL2), rs4647655 (CASP3), rs4645982, and rs61079693 (CASP9), as well as genetic ancestry and clinical data, in a BC cohort from the Brazilian Amazon that other variants in these genes might play a role in this process. In the present study, 22 breast cancer tissues and 10 non-cancerous tissues were used, therefore, 32 samples from different patients were subjected to genotyping. We observed that breastfeeding and cancer history were factors that need to be considered for BC (p = 0.022). Therefore, this study contributed to a greater understanding of intrinsic apoptosis in BC, reinforcing previous data that suggest that the history of cancer might be a condition that affects the development of BC and that breastfeeding may act as a protective factor for this type of cancer. We recommend more studies on the genetic factors investigated here, aiming at a future with tools that can help in the early diagnosis.

Abstract
Background: Ganoderma lucidum (G. lucidum) is a popular traditional remedy medicine used in Asia to promote health and longevity, which has also been highlighted for anti-cancer effects. This study investigated the molecular pharmacological mechanism of G. lucidum triterpenes in influencing intestinal flora imbalance in non-hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) based on 16S rRNA sequencing technology and network pharmacology analysis. Methods: 16S rRNA sequencing data of fecal samples from normal controls and HCC patients were obtained from the SRA database. G. lucidum triterpenes and HCC-related targets were screened by BATMAN-TCM, ETCM, and GeneCards databases. The TCGA-LIHC dataset was downloaded through the TCGA database to analyze the differential expression of key genes. NHBV-related HCC-related transcriptome RNA sequencing dataset was downloaded via the GEO database. Results: Abundance of intestinal flora in the HBV-related HCC and NHBV-related samples was higher than that of control samples. The intestinal flora of NHBV samples was mainly enriched in apoptosis and p53 pathways. Totally, 465 G. lucidum triterpenes-related targets were intersected with 4186 HCC-related targets, yielding 176 intersected targets. Among them, apoptosis and p53 pathway factors were located at the core of the protein-protein interactions network. Ganosporelactone B, the active component of G. lucidum triterpenes, had the lowest binding free energy to CASP3. CASP3 expression were upregulated in HCC tissue samples, and had higher predictive value in NHBV-related HCC patients. Conclusion: Therefore, Ganosporelactone B, the active ingredient of G. lucidum triterpenes, improves the imbalance of intestinal flora and ultimately curtails development of NHBV-related HCC.

Abstract
BACKGROUND Diabetic nephropathy (DN) is one of the common complications of diabetes. Plantaginis Semen (PS) has a variety of therapeutic effects, however its mechanism on DN is unclear. OBJECTIVE This paper aims to find the ingredients, the key targets, and the action pathways of PS on DN from the perspective of network pharmacology. METHOD The databases of network pharmacology, such as Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Pharmmapper, OMIM, DrugBank, GeneCards, TTD, Disgenet, STRING, and Cytoscape software, were used to find the main ingredients and targets. Gene Ontology (GO) function and Kyoto Encyclopedia of Genome and Genomes (KEGG) pathway enrichment analysis were used to reveal the potential pathways of the PS on DN. The GEO database was used to find the targets of DN based on valid experimental research. The molecular docking technology was used to evaluate the combination between ingredients of PS and the targets. RESULTS A total of 9 active ingredients and 216 potential therapeutic targets were obtained for PS on DN. Hub targets were discovered by the Cytoscape software analysis. CASP3 was screened by Venn diagram by making intersection between GSE30529 and hub genes. Moreover, CASP3 was combined with one of the nine active ingredients, quercetin, by molecular docking analysis. The KEGG pathways were mainly involved in diabetic nephropathy, and were simultaneously associated with CASP3 as followed: AGE-RAGE signaling pathway in diabetic complications, apoptosis, lipid and atherosclerosis, MAPK signaling pathway, TNF signaling pathway, IL-17 signaling pathway, and p53 signaling pathway. CONCLUSION PS can have the treatment on DN through CASP3. Quercetin, as one of the nine active ingredients, can be bounded to CASP3 to inhibit apoptosis in DN. PS can also take action on DN probably through many pathways. The role of PS on DN through other pathways still needs to be further elaborated.

Acute myeloid leukemia (AML) is an invasive form of hematologic malignancies which results in the overproduction of myeloid cells in the bone marrow. Aberrant expression of piwi-interacting RNAs (piRNAs) which belong to small non-coding RNAs, play important roles in different cancer cells' progress. hsa- piR- 32877 is up-regulated in AML. Down regulation of hsa-piR-32877 by antisense LNA GapmeRs could be potential for suppression of myeloid cell proliferation and induce myeloid cell apoptosis. We have blocked the expression of hsa-piR-32877 by antisense LNA GapmeRs in human bone marrow blast cells, and the M-07e cell line. Samples were transfected with antisense LNA GapmeRs at 24, 48, and 72 hours. The Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) was performed to investigate the expression of hsa-piR-32877, CASP3, and CASP9. Both CASP3 and CASP9 play important roles in apoptosis. Cell proliferation was studied via CFSE (carboxyfluorescein diacetate succinimidyl ester) assay. Results showed that hsa-piR-32877 was down-regulated by antisense LNA GapmeRs in the patient and cell line samples. Also, after transfection, cell proliferation and apoptosis decreased and increased, respectively. Our data suggested that hsa-piR-32877 suppression may act as a novel therapeutic method for the inhibition of human leukemic cells proliferation in AML.

Abstract
Background N6-methyladenosine (m6A) is found in almost all nuclear RNAs of eukaryotes, playing an important and diverse role in many biological processes. Nonetheless, the roles of m6A regulators in abdominal aortic aneurysm (AAA) unknown. Therefore, there is a pressing need to identify m6A RNA methylation regulators in the diagnosis of AAA, determination of individualized risk, discovery of therapeutic targets, and improve understanding of pathogenesis. Methods The GSE98278 dataset were obtained from the Gene Expression Omnibus (GEO) database to perform differential analysis of m6A-related regulators between elective stable abdominal aortic aneurysms (eAAA) and abdominal aortic aneurysm ruptured (rAAA). The random forest model was used to screen candidate m6A regulators to predict the risk of rAAA. The single sample gene set enrichment analysis (ssGSEA) method was then used to evaluate the abundance of 23 immune cells in AAA. The m6A RNA Methylation Quantification Kit was used to measure the total m6A levels of AAA and normal abdominal aorta. The terminal deoxynucleotidyl transferase mediated dUTP Nick-End Labeling (TUNEL) apoptosis assay kit was used to detect the human aortic smooth muscle cells (HASMCs) apoptotic after RBM15 knockdown. Mechanically, RBM15 knockdown was found to reduce the expression of CASP3 in an m6A-dependent manner by Western blotting, RNA immunoprecipitation (RIP), and methylated RNA immunoprecipitation-quantitative polymerase chain reaction (MeRIP-RT-PCR). Results RBM15, WTAP, ALKBH5, and IGFBP3 were highly expressed in rAAA. In contrast, RBM15B showed opposite results (P<0.05). The high m6A level in the rAAA compared with eAAA and normal abdominal aorta (P<0.05). The random forest model was used to screen 5 candidate m6A regulators to predict the risk of rAAA. Expression of the 5 m6A methylation regulators was validated in AAA samples (P<0.05). RBM15 knockdown inhibited the apoptosis of HASMCs. RBM15 knockdown reduced the expression of CASP3 in an m6A-dependent manner. A strong correlation between the five m6A methylation regulators and immune cell infiltration was identified. Conclusions In summary, m6A regulators play nonnegligible roles in the occurrence of rAAA. Our investigation of m6A patterns may be able to guide future immunotherapy strategies for AAA.

Abstract
Juglone is an allelopathin secreted by black walnut tree of the Juglandaceae family and is used as an active ingredient in many herbal preparations and as a commercial dye. It is considered as an important phytochemical with wide therapeutic potential. Black walnut extract has long been used in folk medicine to treat various types of cancers. It demonstrates antiviral, antibacterial, antifungal, and antitumor activities. The present study aimed to analyze the effect of juglone on the viability and proliferation of melanoma cells of C-32 (amelanotic melanoma) and COLO 829 (melanotic melanoma) cell lines in vitro and on the mRNA expression of genes encoding the proapoptotic BAX protein and caspase 3 and the gene encoding antiapoptotic BCL2 protein. The results showed a dose-dependent effect of juglone on the viability, proliferation, and death induction in C-32 and COLO 829 melanoma cells and in HFF-1 normal dermal fibroblasts in in vitro cultures, but melanoma cells were more sensitive to juglone. Our findings revealed different mRNA expression patterns for all the studied genes in melanoma and normal cells treated with juglone in in vitro cultures.

Abstract
Aims: To evaluate the anti breast-cancer activity, biocompatibility and toxicity of poly(d,l)-lactic-co-glycolic acid (PLGA)-encapsulated quercetin nanoparticles (Q-PLGA-NPs). Materials & methods: Quercetin was nano-encapsulated by an emulsion-diffusion process, and the nanoparticles were fully characterized through Fourier transform infrared spectroscopy, x-ray diffractions, FESEM and zeta-sizer analysis. Activity against CAL51 and MCF7 cell lines were assessed by DNA fragmentation assays, fluorescence microscopy, and acridine-orange, and propidium-iodide double-stainings. Biocompatibility towards red blood cells and toxicity towards mice were also explored. Results: The Q-PLGA-NPs exhibited apoptotic activity against the cell lines. The murine in vivo studies showed no significant alterations in the liver and kidney's functional biomarkers, and no apparent abnormalities, or tissue damages were observed in the histological images of the liver, spleen, lungs, heart and kidneys. Conclusion: The study established the preliminary in vitro efficacy and in vivo safety of Q-PLGA-NPs as a potential anti-breast cancer formulation.

Abstract
Alcoholic liver disease (ALD) is one of the pathogenic factors of chronic liver disease with the highest clinical morbidity worldwide. Ursolic acid (UA), a pentacyclic terpenoid carboxylic acid, has shown many health benefits including antioxidative, anti-inflammatory, anticancer, and hepatoprotective activities. We previously found that UA was metabolized in vivo into epoxy-modified UA containing an epoxy electrophilic group and had the potential to react with nucleophilic groups. In this study we prepared an alkynyl-modified UA (AM-UA) probe for tracing and capturing the target protein of UA from liver in mice, then investigated the mode by which UA bound to its target in vivo. By conducting proteome identification and bioinformatics analysis, we identified caspase-3 (CASP3) as the primary target protein of UA associated with liver protection. Molecule docking analysis showed that the epoxy group of the UA metabolite reacted with Cys-163 of CASP3, forming a covalent bond with CASP3. The binding mode of the UA metabolites (UA, CM-UA, and EM-UA) was verified by biochemical evaluation, demonstrating that the epoxy group produced by metabolism played an important role in the inhibition of CASP3. In alcohol-treated HepG2 cells, pretreatment with the UA metabolite (10 μM) irreversibly inhibited CASP3 activities, and subsequently decreased the cleavage of PARP and cell apoptosis. Finally, pre-administration of UA (20-80 mg· kg-1 per day, ig, for 1 week) dose-dependently alleviated alcohol-induced liver injury in mice mainly via the inhibition of CASP3. In conclusion, this study demonstrates that UA is a valuable lead compound for the treatment of ALD.

Abstract
Breast cancer arises as a result of multiple interactions between environmental and genetic factors. Conventionally, breast cancer is treated based on histopathological and clinical features. DNA technologies like the human genome microarray are now partially integrated into clinical practice and are used for developing new "personalized medicines" and "pharmacogenetics" for improving the efficiency and safety of cancer medications. We investigated the effects of four established therapies-for ER+ ductal breast cancer-on the differential gene expression. The therapies included single agent tamoxifen, two-agent docetaxel and capecitabine, or combined three-agents CAF (cyclophosphamide, doxorubicin, and fluorouracil) and CMF (cyclophosphamide, methotrexate, and fluorouracil). Genevestigator 8.1.0 was used to compare five datasets from patients with infiltrating ductal carcinoma, untreated or treated with selected drugs, to those from the healthy control. We identified 74 differentially expressed genes involved in three pathways, i.e., apoptosis (extrinsic and intrinsic), oxidative signaling, and PI3K/Akt signaling. The treatments affected the expression of apoptotic genes (TNFRSF10B [TRAIL], FAS, CASP3/6/7/8, PMAIP1 [NOXA], BNIP3L, BNIP3, BCL2A1, and BCL2), the oxidative stress-related genes (NOX4, XDH, MAOA, GSR, GPX3, and SOD3), and the PI3K/Akt pathway gene (ERBB2 [HER2]). Breast cancer treatments are complex with varying drug responses and efficacy among patients. This necessitates identifying novel biomarkers for predicting the drug response, using available data and new technologies. GSR, NOX4, CASP3, and ERBB2 are potential biomarkers for predicting the treatment response in primary ER+ ductal breast carcinoma.

Abstract
BACKGROUND Abnormalities in the intrinsic apoptosis pathway, associated with single nucleotide variants (SNVs) in caspase (CASP) genes, alter head and neck squamous cell carcinoma (HNSCC) proliferation and progression. This prospective study aimed to evaluate whether CASP9 c.-1339A>G and CASP3 c.-1191A>G SNVs influence the outcome of patients with HNSCC. Two hundred sixty-two HNSCC patients were enrolled in the study. METHODS DNA and RNA of peripheral blood samples were analyzed using real-time polymerase chain reaction (PCR) for genotyping and quantitative PCR method for gene expression, respectively. Differences in CASP3 expressions were analyzed using the Mann-Whitney test. Event-free survival (EFS) and overall survival (OS) were calculated using the Kaplan-Meier curves, log-rank test, and Cox analyses. RESULTS CASP3 c.-1191AG or GG genotype was associated with higher CASP3 expression when compared with AA genotype (0.50 arbitrary units (AUs) ± 0.29 standard deviation (SD) vs 0.28 AUs ± 0.12 SD; P = .02). Patients with CASP9 c.-1339GG genotype had 1.54 more chance of presenting disease progression or relapse than patients with CASP9 c.-1339AA or AG genotype. Patients with CASP9 c.-1339GG and CASP3 c.-1191GG combined genotype had 2.64 more chance of presenting progression or relapse of the disease and 2.84 more chance of evolving to death than those with the remaining combined genotypes. CONCLUSIONS Our findings provide, for the first time, preliminary evidence that inherited abnormalities in the intrinsic apoptosis pathway, related to CASP9 c.-1339A>G and CASP3 c.-1191A>G SNVs, act as predictors of HNSCC patients' survival.

Abstract
Prostate cancer (PCa) is one of the leading causes of mortality worldwide and often presents with aberrant microRNA (miRNA) expression. Identifying and understanding the unique expression profiles could aid in the detection and treatment of this disease. This review aims to identify miRNAs as potential therapeutic targets for PCa. Three bio-informatic searches were conducted to identify miRNAs that are reportedly implicated in the pathogenesis of PCa. Only hsa-Lethal-7 (let-7c), recognized for its role in PCa pathogenesis, was common to all three databases. Three further database searches were conducted to identify known targets of hsa-let-7c. Four targets were identified, HMGA2, c-Myc (MYC), TRAIL, and CASP3. An extensive review of the literature was undertaken to assess the role of hsa-let-7c in the progression of other malignancies and to evaluate its potential as a therapeutic target for PCa. The heterogeneous nature of cancer makes it logical to develop mechanisms by which the treatment of malignancies is tailored to an individual, harnessing specific knowledge of the underlying biology of the disease. Resetting cellular miRNA levels is an exciting prospect that will allow this ambition to be realized.

Abstract
In a recent study in Oncoimmunology, Rodriguez-Ruiz et al. demonstrate that the apoptotic executioner caspase 3 (CASP3) attenuates antitumor immune responses induced by radiation therapy (RT) by inhibiting the release of cytosolic DNA. CASP3 stands out as a promising target for the development of novel strategies to improve anticancer responses driven by RT.

Abstract
The objective of this research was to assess the association of genetic polymorphisms related to intrinsic apoptosis pathway CASP8 rs3834129 and CASP3 rs4647601 with the risk, clinical and pathological aspects, and survival of oropharynx squamous cell carcinoma (OPSCC) patients that received cisplatin and radiotherapy. The genotypes were identified in 198 patients with OPSCC and 200 controls using polymerase chain reaction methods. Chi square or Fisher's exact test and logistic regression were applied for the detection of differences between groups. Patients' genotypes were statistically evaluated considering the event-free survival and overall analysis using Kaplan-Meier estimate and Cox regression. CASP3 rs4647601 GG genotype (44.4% vs. 30.0%, p = 0.03) and G allele (63.9% vs. 55.5%, p = 0.04) were more common in patients with OPSCC than in controls. Carriers of GG genotype and G allele were under 1.78-fold and 1.40-fold increased risk of OPSCC than others, respectively. The frequency of CASP8 rs3834129 DD genotype was higher in patients with OPSCC with poorly differentiated or undifferentiated tumors when compared to others (34.5% vs. 16.1%, p = 0.02). No influence of CASP8 and CASP3 polymorphisms on OPSCC patients' survival was seen in this study. Our results indicate that inherited genetic variants in the intrinsic apoptosis pathway related to CASP3 rs4647601 and CASP8 rs3834129 polymorphisms may be an important determinant of OPSCC risk and tumor cell differentiation.

Abstract
Caspases are known for their ability to precipitate apoptosis. Our findings indicate that accelerating the terminal inactivation of cells dying in response to radiation therapy limit their immunogenicity as a consequence of reduced type I interferon secretion. Thus, caspase inhibitors stand out as promising combinatorial partners to improve the immunogenicity of radiation therapy in the clinic.

Abstract
This study aimed to investigate the antimitotic and antiproliferation activities of crude acetone-methanol and aqueous extracts of two marine molluscs commonly found in the Niger Delta region of Nigeria; T.fuscatus and P.aurita, against human cancerous cell lines (DU145, Hep-2, and HCC1395) cell lines in vitro. The antimitotic activity of the extracts was evaluated using Allium cepa root meristematic cells. Antiproliferative activity of the plant extracts against the cancerous cell lines was compared with normal cell line (VeroE6). Doxorubicin was used as a positive control. Gene expression studies using qPCR for the proapoptotic genes, CASP3, CASP8 and P53 were also carried out. The alcohol extract of T.fuscatus (TFAC) exhibited the most promising activity against all the cancer cell lines tested (DU145 IC50 = 96.48 ± 1.36 μg/ml, HCC 1395 IC50 = 61.44 ± 2.45 μg/ml, Hep2 IC50 = 0.52 ± 0.36 μg/ml) and also had the highest selectivity index of 4.94, 7.78 and 921.97 for DU145, HCC 1395 and Hep-2 cells respectively. Furthermore, TFAC was the only extract that significantly upregulated the expression of caspase 3, caspase 8 and P53. Thus, these findings suggest potential exploitation of TFAC as an anticancer agent.

Abstract
BACKGROUND Single nucleotide polymorphisms (SNPs) in genes that act in intrinsic apoptosis pathway may modulate cancer susceptibility. This study investigated the roles of CASP9 c.-1339A>G (rs4645978) and CASP3 c.-1191A>G (rs12108497) SNPs on risk and behavior of head and neck (HN) squamous cell carcinoma (SCC). METHODS DNA of 350 patients with HNSCC and 350 controls was analyzed by polymerase chain reaction method for genotyping. RESULTS CASP3 c.-1191AG or GG genotype was more common in patients with HNSCC and oral cavity or oropharynx SCC than in controls; carriers of this genotype were under 2.15 and 2.81-fold increased risks of the respective tumors. CASP9 c.-1339AG or GG plus CASP3 c.-1191AG or GG genotypes were associated with oral cavity or oropharynx SCC early onset. CONCLUSION These findings present, for the first time, preliminary evidence that inherited abnormalities related to CASP9 c.-1339A>G and CASP3 c.-1191A>G SNPs are determinants of HNSCC risk and clinical aspects.

Abstract
BACKGROUND & AIMS Caspase-mediated apoptosis and inflammation contribute to progression of liver disease. Emricasan is a pan-caspase inhibitor that reduced serum markers of apoptosis and liver inflammation in patients with hepatitis C and non-alcoholic steatohepatitis (NASH). METHODS We performed a multicenter study of 86 patients with cirrhosis (Child-Pugh class A or B; mean score, 6.9; 38% with alcohol-associated cirrhosis, 29% with HCV-associated cirrhosis, and 23% with NASH) and model for end-stage liver disease (MELD) scores of 11-18 (mean, 12.8). Patients were randomly assigned to groups given placebo (N = 42) or Emricasan (25 mg, N = 44), twice daily for 3 months; subjects then received open-label Emricasan (25 mg) twice-daily for 3 months. The primary endpoint was the change from baseline in serum levels of cleaved keratin 18 (CK-18) at month 3. RESULTS Seventy-four patients completed the 3-month study period (40 given Emricasan and 34 given placebo); 69 patients received open-label Emricasan for 3 months afterward. At the 3-month timepoint, Emricasan significantly reduced mean MELD (P = .003) and Child-Pugh (P = .003) scores in subjects with high MELD scores (15 or more), compared with placebo, with significant reductions in INR (95% CI, -0.2882 to -0.0866) and total bilirubin (95% CI, -1.5069 to -0.0823) vs placebo. There were no significant differences between Emricasan and placebo groups in mean MELD (P = .466) or Child-Pugh (P = .124) scores overall at 3 months compared to placebo. Of patients with high MELD scores, 6/9 given Emricasan (67%) had a reduction of 2 points or more at month 3, compared with 2/10 given placebo (20%). Serum levels of full-length CK-18 (P = .02) and caspase 3/7 (P < .001), but not cleaved CK-18 (P = .092), decreased significantly at 3 months in the Emricasan vs placebo group. Emricasan was well tolerated, and adverse events were balanced between groups. Emricasan's effects were generally maintained or increased after 6 months of treatment. CONCLUSIONS In a randomized trial of patients with cirrhosis, we found 3 months treatment with Emricasan to improve liver function, compared with placebo, reducing MELD and Child-Pugh scores, INR, and total bilirubin in patients with MELD scores ≥15.

Abstract
Despite advances in our understanding of the biology of chromophobe renal cell carcinoma (ChRCC) and renal oncocytoma (RO), the differential diagnosis among these tumors remains one of the most problematic in renal pathology. Today, CK7 is the most recommended marker to distinguish these entities, however it appears insufficiently accurate by itself. This study aimed to find an easily accessible IHC stain that might out-compete CK7 in this field. Expressions of CK7, cyclin D1, p16, survivin, CD138, Ki-67 and caspase 3 (CASP3) were analyzed in a total of 27 cases (20 ROs and 7 ChRCCs). Immunoreactivity was assessed based on a combined score of the extent and intensity of staining. Compared to RO, a higher percentage of the total ChRCCs stained positive for CK7 (67% vs. 22%, respectively) and CASP3 (86% vs. 25%) (P < 0.005). The differences in staining with cyclin D1, p16, survivin, CD138 and Ki-67 turned out to be statistically insignificant in differentiating ChRCC from RO. CASP3 is a promising marker in distinguishing ChRCC from RO and may represent an alternative for CK7. Cyclin D1, p16, survivin, CD138 and Ki-67 cannot be used to distinguish these neoplasms.

Abstract
Esophageal squamous cell carcinoma (ESCC), the dominant subtype of esophageal cancer, is one of the most common digestive tumors worldwide. In this study, we confirmed that HOXC13, a member of the homeobox HOXC gene family, was significantly upregulated in ESCC and its overexpression was associated with poorer clinical characteristics and worse prognosis. Moreover, knockdown of HOXC13 inhibited proliferation and induced apoptosis of ESCC through upregulating CASP3. ChIP analysis revealed that HOXC13 repressed transcription of CASP3 through directly targeting the promotor region of CASP3. We also found that miR‐503 downregulated HOXC13, by directly targeting its 3′UTR, and inhibited proliferation of ESCC. In conclusion, our study demonstrates that HOXC13, which is directly targeted by miR‐503, promotes proliferation and inhibits apoptosis of ESCC through repressing transcription of CASP3.

Abstract
SCOPE Ursolic acid (UA) is a pentacyclicterpenoid carboxylic acid that is present in a wide variety of plant foods. There are many beneficial health effects that are attributed to the properties of UA. However, the specific cellular targets of UA and the mechanism underlying downstream signal transduction processes linked to the anti-inflammation pathway have not been thoroughly elucidated to date. METHODS AND RESULTS Chemical biology strategies such as target fishing, click reaction synthesis of a UA probe and molecular imaging were used to identify potential target proteins of UA. Cysteinyl aspartate specific proteinase 3 (CASP3) and its downstream signaling pathway were verified as potential targets by molecular docking, intracellular enzyme activity evaluation and accurate pathway analysis. The results indicated that UA acted on CASP3, ERK1 and JNK2 targets, alleviated inflammation-associated downstream multiple signal transduction factors, including ERK1, NF-κB and STAT3, and exhibited anti-inflammation activities. CONCLUSION As a natural dietary supplement, UA demonstrated anti-inflammation activity via inhibition of CASP3 and shows the potential to improve the therapy effect of several inflammation-associated diseases.

Abstract
PURPOSE The aim of this study was to investigate in which part of the lens in vivo exposure to subthreshold dose of UVR-B radiation induces apoptosis. METHODS Twenty 6-week-old female albino Sprague-Dawley rats were exposed to subthreshold dose (1 kJ/m2 ) of UVR-B unilaterally and killed at 120 hr after exposure. Lenses were enucleated and dissected on three regions: the lens epithelium, the cortex and the nucleus. The lens nucleus then was removed. Apoptosis markers p53 and caspase 3 were used to study apoptosis in the lens regions. qRT-PCR and Western blot were utilized to analyse the lenses. RESULTS TP53 and CASP3 mRNA expressions are increased in exposed lenses, both in the lens epithelium and in the cortex regions, in relation to non-exposed lenses. Expression of p53 protein is increased in exposed lens epithelium in relation to non-exposed lens epithelium. Caspase 3 protein is expressed in exposed lens epithelial cells, while it is not expressed in non-exposed lens epithelial cells. p53 and caspase 3 proteins are not expressed in either exposed nor non-exposed lens fibre cells. CONCLUSION Exposure to UVR-B increases mRNA transcription of apoptosis marker p53 in vivo in both regions of the lens and of apoptosis marker caspase 3 in the lens cortex. Exposure to UVR-B increases p53 and caspase 3 proteins expression just in the lens epithelium. In vivo exposure to subthreshold dose of UVR-B induces apoptosis in the lens epithelial cells and does not in the lens fibre cells.

Abstract
BACKGROUND Noise-induced hearing loss (NIHL) is a complex disease caused by environmental and genetic risk factors. This study explored the relationship between the genetic variations in the CASP gene and the risk of developing NIHL among Chinese workers exposed to occupational noise. METHODS A case-control study of 272 NIHL workers and 272 normal-hearing workers matched for age, sex and years of noise exposure was conducted. Fifteen single-nucleotide polymorphisms (SNP) in the CASP1, CASP3, CASP4, CASP5, CASP6, CASP8, CASP9, CASP10 and CASP14 genes were genotyped using the polymerase chain reaction-ligase detection reaction method. Using conditional logistic regression models, the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of genetic variations associated with NIHL risk were calculated. RESULTS Two SNPs in the CASP3 gene were associated with NIHL risk. For rs1049216, TT genotype was associated with a decreased risk of NIHL (OR = 0.246, 95% CI = 0.069-0.886) when compared with the CC genotype. For rs6948, the AC and CC genotype were associated with a decreased NIHL risk (OR = 0.568, 95% CI = 0.352-0.916) compared with AA genotype. There were joint effects of working time and CASP3 polymorphisms on NIHL risk (P < 0.05). CONCLUSIONS Genetic variations in the CASP3 gene and the joint effects of working time and CASP3 polymorphisms may modify the risk of developing NIHL.

Abstract
MicroRNAs (miRNAs) are short and single strand non-coding RNAs that involved in post-transcriptional regulation of gene expression. Dysregulation of miRNA expression is important event in the many of malignant diseases. Up-regulation of Let-7a-5p expression in acute myeloid leukemia in human in previous studies was reported. In this study blockage of Let-7a-5p in human acute promyelocytic leukemia cell line (HL60) was done by using locked nucleic acid (LNA) method and subsequently expression of Let-7a-5p, cell proliferation, apoptosis, necrosis, and CASP3 expression was measured. At three time points 24, 48 and 72 h after LNA anti- Let-7a-5p transfection, assessment of Let-7a-5p expression by qRT real-time PCR was completed. The MTT assay and annexin/PI staining have been performed. Also, CASP3 expression at different time points after LNA anti-Let-7a-5p transfection in HL60 cell line was measured. The results at three-time points after LNA transfection were represented that Let-7a-5p expression was lower in the LNA-anti-Let-7a group compared to the control groups. The cell viability significantly was different between LNA-anti-Let-7a group and control groups. Increasing apoptotic ratio was associated with Let-7a-5p blockage in the LNA-anti-Let-7a group compared with control groups. Also, the necrotic ratio was higher in the LNA-anti-Let-7a group rather than the other groups. Western blotting revealed that CASP3 expression associated with Let-7a-5p inhibition. Our results displayed that blockage of Let-7a-5p can reduced cell viability mainly due to the induction of apoptosis and CASP3 up-regulation in HL60 cells. These results can be useful in translational medicine for research of antisense therapy in leukemia.

Abstract
It is unclear how standing genetic variation affects the prognosis of prostate cancer patients. To provide one controlled answer to this problem, we crossed a dominant, penetrant mouse model of prostate cancer to Diversity Outbred mice, a collection of animals that carries over 40 million SNPs. Integration of disease phenotype and SNP variation data in 493 F1 males identified a metastasis modifier locus on Chromosome 8 (LOD = 8.42); further analysis identified the genes Rwdd4, Cenpu, and Casp3 as functional effectors of this locus. Accordingly, analysis of over 5,300 prostate cancer patient samples revealed correlations between the presence of genetic variants at these loci, their expression levels, cancer aggressiveness, and patient survival. We also observed that ectopic overexpression of RWDD4 and CENPU increased the aggressiveness of two human prostate cancer cell lines. In aggregate, our approach demonstrates how well-characterized genetic variation in mice can be harnessed in conjunction with systems genetics approaches to identify and characterize germline modifiers of human disease processes.

Abstract
The tumor necrosis factor receptor superfamily, member 1A (TNFRSF1A) gene encodes the TNF-R1, one of the main TNF receptors that mediates its inflammatory actions. In a recent study, serum levels of the soluble TNF-R1 and mRNA levels of the full-length receptor were found to be significantly increased in multiple sclerosis (MS) patients carrying the R92Q mutation. Interestingly, R92Q-mutated patients were younger at disease onset and progressed slower as compared to non-carriers. Building on these previous findings, here we aimed to investigate by means of both in silico and in vitro approaches the mechanisms relating the R92Q substitution with functional changes of the receptor and their potential effects modulating MS disease course. Models of the extracellular domains of the human TNF-R1 and human TNF-R1 carrying the R92Q mutation, alone or bound to TNF, were constructed and submitted to molecular dynamics. TRAF2 and CASP3 mRNA expression levels were determined by real-time PCR in peripheral blood mononuclear cells (PBMC) from 61 MS patients, 9 R92Q carriers and 52 non-carriers (CT and CC genotypes for SNP rs4149584, respectively). Molecular dynamic studies revealed that the R92Q mutation increased the contact area between receptor and TNF (1070 and 1388Å(2) for native and mutated receptor) and decreased the distance between them (28.7 to 27.9Å), while Van der Waals and electrostatic interaction energies were increased. In PBMC from MS patients carrying the R92Q mutation, CASP3 mRNA expression levels were significantly increased compared to non-carriers, whereas a trend was observed for TRAF2. These data suggest that the R92Q mutation gives rise to a stronger interaction between the receptor and its ligand, which results in the potentiation of TNF-mediated pathways. Although further studies are needed, these functional changes may be related with the modulation in disease course reported in MS patients carrying the R92Q mutation.

Abstract
GAP43 is a protein involved in neurite outgrowth during development and axon regeneration reflecting its presynaptic localization in developing neurons. Recently, it has been demonstrated that GAP43 is a ligand of CASP3 involved in receptor endocytosis and is also localized post-synaptically. In this study, by using a transgenic mouse strain carrying a bioluminescent reporter for GAP43 combined with an in vivo bioluminescence assay for CASP3, we demonstrated that one day after brain ischemic lesion and, even more pronounced, four days after stroke, expression of both CASP3 and Gap43 in neurons increased more than 40 times. The in vivo approach of CASP3 and GAP43 colocalization imaging was further validated and quantified by immunofluorescence. Importantly, in 82% of GAP43 positive cells, colocalization with CASP3 was present. These findings suggested that one and four days after stroke CASP3 expression, not necessarily associated with neuronal death, increased and suggested that CASP3 and GAP43 might be part of a common molecular pathway involved in early response to ischemic events occurring after onset of stroke.

Abstract
Hyperglycemia is one of the possible causes for osteoporosis and bone fracture in diabetes mellitus. Here we modeled diabetes-induced osteoporosis in vitro using preosteoblastic cell line MC3T3-E1 and a diabetic mice model for in vivo studies. We found that in addition to reducing osteoblast viability and differentiation (mineralization), culture in elevated glucose down regulated microRNA-378 (miR-378) expression but ectopic miR-378 expression reversed the effects of high glucose. We identified caspase-3 (CASP3) as a target of miR-378 and showed that miR-378 repressed CASP3 mRNA and protein expression under high glucose condition. We further showed that both miR-378 expression and CASP3 silencing independently restored alkaline phosphatase (ALP) activity and the expression of osteoblastic differentiation markers Runt-related transcription factor 2 (Runx2), osteorix (Osx), collagen I (Col I), osteocalcin (OCN), and osteonectin (ON). We also found that under high glucose conditions miR-378 activated the PI3K/Akt signaling pathway and down regulated pro-apoptotic CytC, Apaf-1 and Bax proteins via the PI3K/Akt pathway. Collectively, these results suggest that miR-378 overexpression attenuates high glucose-suppressed osteogenic differentiation through targeting CASP3 and activating the PI3K/Akt pathway.

Abstract
The use of array comparative genomic hybridization (array CGH) as a diagnostic tool in molecular genetics has facilitated the identification of many new microdeletion/microduplication syndromes (MMSs). Furthermore, this method has allowed for the identification of copy number variations (CNVs) whose pathogenic role has yet to be uncovered. Here, we report on our application of array CGH for the identification of pathogenic CNVs in 79 Russian children with intellectual disability (ID). Twenty-six pathogenic or likely pathogenic changes in copy number were detected in 22 patients (28%): 8 CNVs corresponded to known MMSs, and 17 were not associated with previously described syndromes. In this report, we describe our findings and comment on genes potentially associated with ID that are located within the CNV regions.

Abstract
Metals are a threat to human health by increasing disease risk. Experimental data have linked altered miRNA expression with exposure to some metals. MiRNAs comprise a large family of non-coding single-stranded molecules that primarily function to negatively regulate gene expression post-transcriptionally. Although several human populations are exposed to low concentrations of As, Cd and Pb as a mixture, most toxicology research focuses on the individual effects that these metals exert. Thus, this study aims to evaluate global miRNA and mRNA expression changes induced by a metal mixture containing NaAsO2, CdCl2, Pb(C2H3O2)2·3H2O and to predict possible metal-associated disease development under these conditions. Our results show that this metal mixture results in a miRNA expression profile that may be responsible for the mRNA expression changes observed under experimental conditions in which coding proteins are involved in cellular processes, including cell death, growth and proliferation related to the metal-associated inflammatory response and cancer.
