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: DNA methylation is a crucial epigenetic modification that regulates gene expression and genome stability. The methylation inhibitor, AzaD, can effectively reduce genome-wide hypomethylation and cause a series of epigenetic variations.

Summary: By utilizing epigenetic molecules and small molecules, the expression of pluripotency genes can be induced and methylation in the OCT4 promoter can be reduced in human somatic cells, enhancing reprogramming efficiency. Further studies are needed to elucidate the mechanisms by which these compounds exert their effects on reprogramming.

Summary: The study demonstrated that 5-AZA-DC can alleviate the symptoms of preeclampsia by modulating the expression and interaction of STAT3, PTEN, and TSC2. It also promotes cell proliferation, inhibits apoptosis, and relieves the physiological abnormalities induced by PE.

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: 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: The study revealed that AZA modulated the LTA-induced inflammatory response through the NF-κB signaling pathway in hOBs, enhancing the production of specific inflammatory cytokines. Additionally, AZA had a significant impact on the NF-κB and MAPK signaling pathways in LTA-stimulated hOBs, further confirming the roles of these pathways in hOBs treated with LTA.

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: 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: 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 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.
