Mycoplasma DnaK expression increases cancer development in vivo upon DNA damage. Proc Natl Acad Sci U S A 2024; 121:e2320859121. [PMID: 38412130 DOI: 10.1073/pnas.2320859121] [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: 11/27/2023] [Accepted: 01/24/2024] [Indexed: 02/29/2024] Open
Abstract
Well-controlled repair mechanisms are involved in the maintenance of genomic stability, and their failure can precipitate DNA abnormalities and elevate tumor risk. In addition, the tumor microenvironment, enriched with factors inducing oxidative stress and affecting cell cycle checkpoints, intensifies DNA damage when repair pathways falter. Recent research has unveiled associations between certain bacteria, including Mycoplasmas, and various cancers, and the causative mechanism(s) are under active investigation. We previously showed that Mycoplasma fermentans DnaK, an HSP70 family chaperone protein, hampers the activity of proteins like PARP1 and p53, crucial for genomic integrity. Moreover, our analysis of its interactome in human cancer cell lines revealed DnaK's engagement with several components of DNA-repair machinery. Finally, in vivo experiments performed in our laboratory using a DnaK knock-in mouse model generated by our group demonstrated that DnaK exposure led to increased DNA copy number variants, indicative of genomic instability. We present here evidence that expression of DnaK is linked to increased i) incidence of tumors in vivo upon exposure to urethane, a DNA damaging agent; ii) spontaneous DNA damage ex vivo; and iii) expression of proinflammatory cytokines ex vivo, variations in reactive oxygen species levels, and increased β-galactosidase activity across tissues. Moreover, DnaK was associated with increased centromeric instability. Overall, these findings highlight the significance of Mycoplasma DnaK in the etiology of cancer and other genetic disorders providing a promising target for prevention, diagnostics, and therapeutics.

Pharmaceuticals (Basel) 2023; 16:986. [PMID: 37513898 PMCID: PMC10384399 DOI: 10.3390/ph16070986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 06/15/2023] [Accepted: 06/25/2023] [Indexed: 07/30/2023] Open
Abstract
Cancer therapies based on nanoparticles with a loaded drug can overcome the problem of the drug's toxic effects in the traditional chemotherapeutic approach. In this study, we loaded LLY-507, a potent inhibitor of SMYD2, a methyltransferase enzyme, on iron oxide nanoparticles (IONPs). The prepared nanoparticles were characterized by microscopic analysis, loading efficiency, and drug release studies. Microscopic examination revealed an average grain size of 44 nm. The in vitro effect of LLY-507-IONPs, LLY-507, and IONPs was determined by MTT analysis (A549 cells) and hemolysis studies. IONPs have almost negative hemolytic activity in blood. The cell viability assay revealed IC50 values of both LLY-507 alone and LLY-507-loaded IONPs against A549; the lower value of the drug loaded on NPs (0.71 µg/mL alone and 0.53 µg/mL loaded on NPs) shows strong synergistic anticancer potential. We further tested the role of loaded NPs in a urethane-induced lung cancer mouse model (n = 40 mice in three independent trials, 20 mice in control group) to check the role of SMYD2 at various time points of lung cancer development. The loss of SMYD2 due to LLY-507 suppressed tumor growth, emphysema, hemorrhage, and congestion considerably. Hence, it can be concluded that the SMYD2 inhibitor has an anti-inflammatory effect on the mouse lung and suppresses tumor growth by inhibiting the SMYD2 protein.

Abstract
Lung cancer progresses without obvious symptoms and is detected in most patients at late stages, causing a high rate of mortality. Avocado peels (AVP) were thought to be biowaste, but they have antioxidant and anticancer properties in vitro. Chitosan nanoparticles (Cs-NPs) were loaded with various plant extracts, increasing their in vitro and in vivo anticancer activities. Our goal was to load AVP onto Cs-NPs and determine the role of AVP-extract or AVP-loaded Cs-NPs in controlling the progression of lung cancer caused by urethane toxicity. The AVP-loaded chitosan nano-combination (Cs@AVP NC) was synthesized and characterized. Our in vitro results show that Cs@AVP NC has higher anticancer activity than AVP against three human cancer cell lines. The in vivo study proved the activation of apoptosis in lung cancer cells with the Cs@AVP NC oral treatment more than the AVP treatment. Additionally, Cs@AVP NC-treated animals showed significantly higher p53 and Bax-expression levels and lower NF-κB p65 levels in their lung tissues than in positive control animals. In conclusion, our study demonstrated the superior anticancer potency of Cs@AVP NC over AVP extract and its ability to inhibit lung cancer proliferation. Therefore, oral consumption of Cs@AVP NC might be a promising treatment for lung cancer.

Abstract
Non-small cell lung cancer (NSCLC), the most common type of lung cancer, etiologically associates with tobacco smoking which mechanistically contributes to oxidative stress to facilitate the occurrence of mutations, oncogenic transformation and aberrantly activated signaling pathways. Our previous reports suggested an essential role of Sulfiredoxin (Srx) in promoting the development of lung cancer in humans, and was causally related to Peroxiredoxin IV (Prx4), the major downstream substrate and mediator of Srx-enhanced signaling. To further explore the role of the Srx-Prx4 axis in de novo lung tumorigenesis, we established Prx4-/- and Srx-/-/Prx4-/- mice in pure FVB/N background. Together with wild-type litter mates, these mice were exposed to carcinogenic urethane and the development of lung tumorigenesis was evaluated. We found that disruption of the Srx-Prx4 axis, either through knockout of Srx/Prx4 alone or together, led to a reduced number and size of lung tumors in mice. Immunohistological studies found that loss of Srx/Prx4 led to reduced rate of cell proliferation and less intratumoral macrophage infiltration. Mechanistically, we found that exposure to urethane increased the levels of reactive oxygen species, activated the expression of and Prx4 in normal lung epithelial cells, while knockout of Prx4 inhibited urethane-induced cell transformation. Moreover, bioinformatics analysis found that the Srx-Prx4 axis is activated in many human cancers, and their increased expression is tightly correlated with poor prognosis in NSCLC patients.

Abstract
Lung cancer is the most common cause of cancer death worldwide. Thereby, new treatment strategies as targeting nano-therapy present promising possibilities to control the aggressiveness of lung cancer. Dual CD44 and folate receptors targetable nanocapsule based on folic-polyethylene glycol-hyaluronic (FA-PEG-HA) were fabricated to improve the therapeutic activity of 4-Methylumbelliferone (4-MU) toward lung cancer. In this study, we fabricate 4-MU Nps as a hybrid polymeric (protamine) protein (albumin) nanocapsule, then functionalized by targeting layer to form 4-MU@FA-PEG-HA Nps with encapsulation efficacy 96.15%. The in vitro study of free 4-MU, 4-MU Nps and 4-MU@FA-PEG-HA Nps on A549 lung cancer cells reveal that the 4-MU Nps and 4-MU@FA-PEG-HA Nps were more cytotoxic than free 4-MU on A549 cells. The observed therapeutic activity of 4-MU@FA-PEG-HA Nps on urethane-induced lung cancer model, potentiality revealed a tumor growth inhibition via apoptotic mechanisms and angiogenesis inhibition. The results were supported by Enzyme-linked immunosorbent assay (ELIZA) of transforming growth factors (TGFβ1) and serum HA, histopathological analysis as well as immunohistochemical Ki67, CD44, Bcl-2 and caspace-3 staining. Moreover, 4-MU@FA-PEG-HA Nps exhibited a promising safety profile. Hence, it is expected that our developed novel nano-system can be used for potential application on tumor therapy for lung cancer.

Abstract
Lung cancer is one of the most common types of malignant tumors of the respiratory system and has the highest rates of incidence and mortality of malignant tumors. This study aimed to synthesize and characterize berberine-loaded chitosan nanoparticles (BBR-COSNPs) and to evaluate their protective effects against urethane-induced lung cancer. Forty male albino mice were divided into four groups, with the first serving as a negative control and the other three groups were injected intraperitoneally with urethane (1 mg/kg b.w) each other day for 1 week then group 2 was served as a positive control, however, groups 3 and 4 were treated orally with a daily dose of BBR or BBR-COSNPs (75 mg/kg b.w) for 10 consecutive weeks. Blood and lung tissue samples are collected for laboratory assay. The BBR-COSNPs were spherical, with an average particle size of 45.56 nm and zeta potential of 39.82 1.82 mV. The in vivo data demonstrated that mice given urethane alone had a significant increase in MDA, NO, NF-κB level, HIF1-α, and COX-2-positive expression in the lung tissue and serum VEGFR2, ALT, AST, urea, and creatinine accompanied with a significant decrease in GSH, SOD, caspase 9 in the lung tissue and serum BAX. Co-treatment with BBR-COSNPs suppressed lung cancer growth and promoted apoptosis by modulating serum BAX and lung caspase 9 gene expressions. In addition, BBR-COSNPs inhibited tumor angiogenesis by reduction in levels of serum VEGFR2 and lung HIF 1 gene expression. It is possible to conclude that BBR-COSNPs can be used in oral administration formulations for lunganticancer therapy.

Inflammation during Lung Cancer Progression and Ethyl Pyruvate Treatment Observed by Pulmonary Functional Hyperpolarized 129Xe MRI in Mice. CONTRAST MEDIA & MOLECULAR IMAGING 2021; 2021:9918702.

Abstract
This study aimed to assess the suitability of hyperpolarized 129Xe (HPXe) MRI for noninvasive longitudinal evaluation of pulmonary function in preclinical lung cancer models. A mouse model of lung cancer (LC) was induced in 5 mice by intraperitoneal injection of urethane, while a negative-control (NC) mice (N = 5) was prepared by injection of saline solution. Longitudinal HPXe MRI was performed over a 5-month period to monitor lung ventilation and gas exchange. The treatment efficacy of ethyl pyruvate (EP), an anti-inflammatory drug, to the mouse LC model was monitored using HPXe MRI by commencing administration of EP pre (early-phase) and 1-month post (late-phase) injection of urethane (N = 5 mice for each group). Gas-exchange function in LC mice was significantly reduced at 1-month after urethane injection compared with NC mice administered with saline (P < 0.01). Thereafter, it remained consistently lower than that of the NC group for the full 5-month measurement period. In contrast, the ventilation function of the LC model mice was not significantly different to that of the NC mice. Histological analysis revealed alveolar epithelial hyperplasia in LC mice alveoli at 1 month after urethane injection, and adenoma was confirmed 3 months after the injection. The early- and late-phase EP interventions were found to improve HPXe MRI metrics (reduced at 1 month postinjection of urethane) and significantly inhibit tumor growth. These results suggest that HPXe MRI gas-exchange metrics can be used to quantitatively assess changes in the precancerous lesion microenvironment and to evaluate therapeutic efficacy in cancer. Thus, HPXe MRI can be utilized to noninvasively monitor pulmonary pathology during LC progression and can visualize functional changes during therapy.

Abstract
The Wilms' tumor 1 (WT1) gene is well known as a chameleon gene. It plays a role as a tumor suppressor in Wilms' tumor but also acts as an oncogene in other cancers. Previously, our group reported that a canonical AUG starting site for the WT1 protein (augWT1) acts as a tumor suppressor, whereas a CUG starting site for the WT1 protein (cugWT1) functions as an oncogene. In this study, we report an oncogenic role of cugWT1 in the AOM/DSS-induced colon cancer mouse model and in a urethane-induced lung cancer model in mice lacking cugWT1. Development of chemically-induced tumors was significantly depressed in cugWT1-deficient mice. Moreover, glycogen synthase kinase 3β promoted phosphorylation of cugWT1 at S64, resulting in ubiquitination and degradation of the cugWT1 associated with the F-box-/- WD repeat-containing protein 8. Overall, our findings suggest that inhibition of cugWT1 expression provides a potential candidate target for therapy. SIGNIFICANCE: These findings demonstrate that CUG-translated WT1 plays an oncogenic role in vivo, and GSK3β-mediated phosphorylation of cugWT1 induces its ubiquitination and degradation in concert with FBXW8.

Abstract
The identification of oncogenic biomolecules as drug targets is an unmet need for the development of clinically effective novel anticancer therapies. In this study, we report for the first time that opsin 4/melanopsin (OPN4) plays a critical role in the pathogenesis of non-small cell lung cancer (NSCLC) and is a potential drug target. Our study has revealed that OPN4 is overexpressed in human lung cancer tissues and cells, and is inversely correlated with patient survival probability. Knocking down expression of OPN4 suppressed cells growth and induced apoptosis in lung cancer cells. We have also found that OPN4, a G protein-coupled receptor, interacted with Gα11 and triggered the PKC/BRAF/MEK/ERKs signaling pathway in lung adenocarcinoma cells. Genetic ablation of OPN4 attenuated the multiplicity and the volume of urethane-induced lung tumors in mice. Importantly, our study provides the first report of AE 51310 (1-[(2,5-dichloro-4-methoxyphenyl)sulfonyl]-3-methylpiperidine) as a small-molecule inhibitor of OPN4, suppressed the anchorage-independent growth of lung cancer cells and the growth of patient-derived xenograft tumors in mice. IMPLICATIONS: Overall, this study unveils the role of OPN4 in NSCLC and suggests that targeting OPN4 with small molecules, such as AE 51310 would be interesting to develop novel anticancer therapies for lung adenocarcinoma.

Abstract
Background The expression of desmosomal genes in lung adenocarcinoma and lung squamous carcinoma is different. However, the regulatory mechanism of desmosomal gene expression in lung adenocarcinoma and lung squamous carcinoma remains unknown. Methods The correlation between expression of desmosomal gene expression and SOX30 expression were analyzed by bioinformatics. The expression of SOX30, DSP, JUP and DSC3 were detected in lung cancer cell lines, lung tissues of mice and patients’ tissues by qPCR, WB, Immunofluorescence and Immunohistochemistry. A chromatin Immunoprecipitation assay was used to investigate the mechanisms of the SOX30 regulation on desmosomal gene expression. In vitro proliferation, migration and invasion assays, and an in vivo nude mice model were utilized to assess the important role of desmosomal genes on SOX30-induced tumor suppression. A WB assay and TOP/FOP flash reporter assay was used to investigate the downstream pathway regulated by the SOX30-desmosomal gene axis. A chemical carcinogenic model of SOX30-knockout mice was generated to confirm the role of the SOX30-desmosomal gene axis in tumorigenesis. Results The expression of desmosomal genes were upregulated by SOX30 in lung adenocarcinoma but not in lung squamous carcinoma. Further mechanism studies showed that SOX30 acts as a key transcriptional regulator of desmosomal genes by directly binding to the ACAAT motif of desmosomal genes promoter region and activating their transcription in lung adenocarcinoma. Knockdown of the expression of related desmosomal genes by miRNA significantly attenuated the inhibitory effect of SOX30 on cell proliferation, migration and invasion in vitro and on tumor growth and metastasis in vivo. In addition, knockout of SOX30 promotes lung tumor development and loss the inhibition of desmosomal genes on downstream Wnt and ERK signal in urethane-induced lung carcinogenesis in SOX30-knockout mice. Conclusions Overall, these findings demonstrate for the first time that SOX30 acts as a master switch of desmosomal genes, inhibits lung adenocarcinoma cell proliferation, migration and invasion by activating the transcription of desmosomal genes. This study provides novel insights on the regulatory mechanism of desmosomal genes in lung adenocarcinoma.

Abstract
Tumor necrosis factor receptor (TNFR)-associated factor 1 (TRAF1) is a unique TRAF protein that can interact directly or indirectly with multiple TNFR family members, regulatory proteins, kinases, and adaptors that contribute to its diverse functions in specific tissues. However, the role of TRAF1 in non-small cell lung cancer (NSCLC) remains unknown. In this study, we report that TRAF1 is overexpressed in human lung cancer cells and tissues. TRAF1 expression level inversely correlated with patient survival probability. Loss of TRAF1 decelerated tumor invasion in a urethane-induced lung carcinogenesis mouse model. Furthermore, TRAF1 expression affected TRAF2-mediated BRAF Lys48-linked ubiquitination, which was followed by the inhibition of growth and differentiation, and the induction of death in lung cancer cells. Overall, our work suggests that TRAF1 plays a novel role in the regulation of the BRAF/MEK/ERK signaling pathway in NSCLC and offers a candidate molecular target for lung cancer prevention and therapy.Significance: These findings identify TRAF1 as a new therapeutic target for NSCLC.

[PMID: 28669687 DOI: 10.1016/j.jacl.2017.05.004] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2017] [Revised: 05/16/2017] [Accepted: 05/23/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Emerging evidence has connected lipid metabolism disturbance with lung diseases, but the relationship between blood lipid profile and lung cancer risk is controversial and inconclusive. OBJECTIVE We conducted a meta-analysis of prospective cohort studies to evaluate the relationship between blood lipids profile and lung cancer incidence. METHODS Relevant studies were identified by searching PubMed, Cochrane Library, Web of Science, EBSCO, Ovid, CNKI, VIP, and WANGFANG MED through August 2016. Nine prospective cohort studies were included in the meta-analysis, and fixed or random effects model was used to calculate pooled relative risk (RRs). The RR was calculated using either highest vs lowest categories, or upper quantile vs lowest quantile. The thresholds were determined by the authors of each original publication, based on either predefined cut-offs or the distributions within their study population. RESULTS Analysis of 18,111 lung cancer cases among 1,832,880 participants showed that serum total cholesterol levels were inverse associated with lung cancer risk (RR = 0.93, 95% confidence interval [CI]: 0.85-1.03). Further analysis considered the lag time and excluded the effects of preclinical cancer, with totally 1,239,948 participants and 14,052 lung cancer cases, found a significantly inverse association between total cholesterol and lung cancer risk (RR = 0.89, 95% CI: 0.83-0.94). Analysis of 3067 lung cancer cases among 59,242 participants found that the high-density lipoprotein cholesterol levels (RR = 0.76, 95% CI: 0.59-0.97) was negatively associated with lung cancer risk and 4673 lung cancer cases among 685,852 participants showed that the total triglyceride (RR = 1.68, 95% CI: 1.44-1.96) was positively associated with lung cancer risk. CONCLUSION Cholesterol and fatty acid metabolism might present different and specific mechanism on lung cancer etiology and needs further elucidation.
