Summary: This study found that the demethylating agent Aza inhibits gene activity while Cd induces MT2 gene expression, but neither has an effect on global DNA methylation levels. Thus, Cd detoxification based on MT2 induction is not related to changes in DNA methylation.

Summary: The aim of this study was to investigate the effect of the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (Aza) on early renal injury. The results showed that low-dose Aza attenuated apoptosis and inflammation, and improved renal function. Furthermore, low-dose Aza upregulated the expression of Klotho protein, and the inhibition of Klotho protein reversed the protective effects of low-dose Aza on apoptosis and inflammation.

Summary: DNA methylation, mediated by DNA methyltransferase, affects gene expression and plays a role in malignant diseases. The classic inhibitor 5-Aza inhibits tumor cell proliferation and induces cell cycle arrest. It increases tumor suppressive proteins and transcription factors, while decreasing oncogene expression. These results suggest potential clinical applications in prostate cancer treatment.

Summary: Functional experiments showed that combining 5-ADC and PDT had a synergistic effect in vitro and increased cytotoxicity in TNBC 4T1 tumor cells. Treatment with 5-ADC/PDT showed histopathologically defined margins of necrosis and increased T cell expression, indicating an anti-tumor immune response. Bioinformatics analysis identified altered immune response biomarkers in TNBC compared to other breast cancer subtypes.

Summary: This study investigated the molecular effects of DNA methyltransferase inhibitor in response to treatment in normoxia and hypoxia in breast cancer model. It was found that the inhibitor upregulated proinflammatory pathways, with a greater effect observed in normoxia than hypoxia. Specifically, NF-kappa B expression increased only in normoxia after treatment with the inhibitor, suggesting a potential context-dependent impact on inflammatory response in the tumor microenvironment.

Summary: The study demonstrates the methylation modification of GAS5 in melanoma and the reversible effect of 5-Aza-dC on this modification. Treatment with 5-Aza-dC inhibits cell proliferation, increases apoptosis, and reduces migration and invasion in melanoma cells. The antitumor effect of 5-Aza-dC in melanoma is related to the methylation modification of GAS5.

Summary: DNMT1 depletion is a rational goal in DNA methylation-dependent disorders, and current agents like decitabine and azacitidine have off-target activities limiting their use. Aza-T-dCyd is a promising candidate with less toxicity and higher therapeutic index for selectively depleting DNMT1. Further research is needed to understand its mechanism of action and potential clinical applications.

Summary: Our study demonstrated that 5-aza inhibits adipogenic differentiation of MG-63 cells, while SAHA enhances it. Genome-wide expression analysis revealed high variability within samples and distinct expression profiles for cells derived with 5-aza. Differential analysis identified numerous DE genes and transcription factors across different pairwise comparisons. Additionally, GO terms related to enhanced adipogenesis and up-regulation of certain signaling pathways were enriched in 5-aza treated cells. Further research is required to understand the roles of these genes in adipogenesis.

Summary: This study demonstrates that the DNA methyltransferase inhibitor 5-AZA-dC can increase branching and sialylation of N-glycans in cancer cells, and regulates glycosyltransferases through GATA transcription factors. Treated cells, especially in chemo-sensitive cell lines, showed increased migration and apoptotic markers. The findings provide insight into the impact of epigenetic alterations on cancer cell glycosylation.

Summary: Inflammasomes play a critical role in tumor development, and their components have significant effects on tumorigenesis in a tissue-specific and stage-dependent manner. The proinflammatory cytokines produced by inflammasome activation can regulate tissue homeostasis and induce antitumor immune responses, but they can also promote cancer growth and proliferation by directing oncogenic signaling pathways in cancer cells. Epigenetic mechanisms and autophagy control inflammasome activation and contribute to cancer development.

Summary: Clusterin induces autophagy in oral cancer through the AMPK/Akt/mTOR signaling pathway, protecting cells from apoptosis, interacts with ULK1 to induce autophagy, and promotes mitophagy in nutrient deprivation conditions. High CLU expression is associated with therapy resistance and clusterin-mediated mitophagy inhibits cell death by cisplatin in cancer cells.

Summary: Gene expression is crucial for cellular functions and homeostasis, with histone modifications playing a role in regulating gene expression. Recent studies have shown how tissue transglutaminase 2 mediated histone glutamine modifications can regulate gene expression, opening new avenues in the field of epigenetics and neuroepigenetics. The research aims to identify enzymes responsible for reversible reactions of histone de-dopaminylation and de-serotonylation.

Summary: In this study, fruit peels waste was collected from a residential and fruit-juice center in Purba Medinipur district of West Bengal, India. The powder generated from these wastes was analyzed, and it was found to have heterogeneous particles with a diameter ranging from 10 to 55 μm and a moisture content of approximately 4%. Various minerals and 33 bioactive molecules were detected in the powder. Different extracts were prepared from the powder using solvents and showed high antioxidant properties. Methanol, ethanol, petroleum ether, and butanol extracts exhibited cytotoxic potential against Pseudomonas aeruginosa MZ269380, and all extracts were biocompatible with goat's erythrocytes at MIC concentration. The biovalorization of fruit peels can produce useful phytochemicals for biomedical, food processing, and cosmetics industries.

Summary: Understanding the molecular mechanism(s) of small compounds in cellular growth control is crucial for combating diseases. Oral cancers have a high mortality rate due to their metastatic potential. Aberrant EGFR, RAR, HH signaling, elevated [Ca2+] and oxidative stress are important characteristics of oral cancer. Therefore, we targeted these features for our study. We tested the effects of fendiline hydrochloride (FH), erismodegib (a SMO inhibitor), and all-trans retinoic acid (RA) on cellular differentiation.

Summary: Chromatin modifications, such as DNA methylation, histone modification, and recruitment of noncoding RNAs, play essential roles in epigenetic events. These modifications converge into a complex epigenetic landscape, involving the recognition of promoter DNA methylation by MeCP2/methyl CpG binding domain proteins and the recruitment of SETDB1/SUV39 to establish higher order chromatin structure. While many studies have provided new information on different epigenetic modifications and associated factors, clear maps of interconnected pathways are also emerging. This review focuses on the significant crosstalk mechanisms utilized by cells for various cellular processes and how deregulation or aberrant gene expression contributes to disease progression.

Summary: SOX2 plays a critical role in tumor development, cancer stem cell maintenance, and cancer progression. The mechanisms of SOX2 gene regulation in human breast and prostate cancers are still unknown. This study found that both prostate and breast cancer tissues showed high expression of SOX2, and inhibiting SOX2 significantly decreased cell proliferation and migration. Epigenetic modulators enhanced SOX2 expression, and histone modifications were crucial for the overexpression of SOX2 during tumorigenesis. Co-targeting SOX2 and its active epigenetic modifier enzymes could be a potential strategy for effectively treating aggressive prostate and breast cancers.

Summary: Over the past fifty years, there have been changing views on the organization and dynamics of the plasma membrane at the molecular level. Lipid rafts, nanoscale subdomains enriched with cholesterol and sphingolipids, play a unique role among other subdomains by dynamically harboring signaling proteins and orchestrating multiple signaling pathways. They are involved in cellular physiology, homeostasis, embryonic development, stem cell maintenance, and cancer biology.
