The epigenetic layer of regulation has become increasingly relevant in the research focused on tumor suppressors. is a well-described zinc-finger transcription factor, mainly known for its role in the acquisition of cell pluripotency. Here we report and describe the most relevant epigenetic regulation mechanisms that affect expression in tumors. CpG island methylation emerges as the most common mechanism in several tumors including lung adenocarcinoma, hepatocellular carcinoma, non-Hodgkin lymphomas, among others. Further layers of regulation represented by histone methylation and acetylation and by non-coding RNAs are described. Overall, emerges as a crucial target in the fight against cancer.

Cellular reprogramming of somatic cells towards induced pluripotency is a multistep stochastic process mediated by the transcription factors Oct4, Sox2, Klf4 and c-Myc (OSKM), which orchestrate global epigenetic and transcriptional changes. We performed a large-scale analysis of integrated ChIP-seq, ATAC-seq and RNA-seq data and revealed the spatiotemporal highly dynamic pattern of OSKM DNA binding during reprogramming. We found that OSKM show distinct temporal patterns of binding to different classes of pluripotency-related enhancers.

A critical area of recent cancer research is the emergence of transition states between normal and cancer that exhibit increased cell plasticity which underlies tumor cell heterogeneity. Pancreatic ductal adenocarcinoma (PDAC) can arise from the combination of a transition state termed acinar-to-ductal metaplasia (ADM) and a gain-of-function mutation in the proto-oncogene . During ADM, digestive enzyme-producing acinar cells acquire a transient ductal epithelium-like phenotype while maintaining their geographical acinar organization.

Butyric acid as a short-chain fatty acid (SCFA) is one of the key microbial metabolites of ruminants. Numerous studies indicate that butyrate is crucial in muscle growth and development, and plays an important molecular regulatory role mainly by inhibiting histone deacetylation. DNA methylation, a major epigenetic modification, is involved in cell differentiation.

Background: Allergic rhinitis (AR) represents a hallmark of obvious hypersensitivity with an imbalance of immune responses, including abnormal macrophage activity in local tissues. It has been reported that alternatively activated macrophages (M2) may contribute to allergic pathogenesis. Ten-eleven translocation (Tet) enzymes can oxidize 5-methylcytosine (m5C) in mRNA, implying the epigenetic regulation of post-transcriptional RNA modification.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most prevalent genetic disorder affecting the kidneys. Understanding epigenetic regulatory mechanisms and the role of microRNAs (miRNAs) is crucial for developing therapeutic interventions. Two mRNA datasets (GSE7869 and GSE35831) and miRNA expression data (GSE133530) from ADPKD patients were used to find differentially expressed genes (DEGs) and differentially expressed miRNAs (DEMs), with a focus on genes regulated by hub transcription factors (TFs) and their target genes.
