Cytosine modification on DNA is variable among individuals, which could correlate with gene expression variation. The effect of cytosine modification on interindividual transcript isoform variation (TIV), however, remains unclear. In this study, we assessed the extent of cytosine modification-specific TIV in lymphoblastoid cell lines (LCLs) derived from unrelated individuals of European and Afr...

An organism's behavioural and physiological and social milieu influence and are influenced by the epigenome, which is comprised predominantly of chromatin and the covalent modification of DNA by methylation. Epigenetic patterns are sculpted during development to shape the diversity of gene expression programmes in the organism. In contrast with the genetic sequence, which is determined by inher...

Similar to protein-coding genes, miRNAs are also susceptible to epigenetic modulation. Although numerous miRNAs have been shown to be affected by DNA methylation, the regulatory mechanism of histone modification on miRNA is not adequately understood. EZH2 and HDACs were recently identified as critical histone modifiers of deregulated miRNAs in cancer and can be recruited to a miRNA promoter by ...

Epigenetic modification can mediate environmental influences on gene expression and can modulate the disease risk associated with genetic variation. Epigenetic analysis therefore holds substantial promise for identifying mechanisms through which genetic and environmental factors jointly contribute to disease risk. The spatial and temporal variance in epigenetic profile is of particular relevanc...

The genetic and epigenetic alteration was commonly related to the progression of breast cancer. Epigenetic which comprises DNA methylation microRNA is involved in controlling gene expression cancer cells. change cellular transformation, tumorigenesis, stemness marker were accomplished by this modification. short, non-coding RNAs, are called microRNAs (miRNAs) considered as a master regulator ge...

This study explores how allopolyploidization reshapes the biased expression and asymmetric epigenetic modification of homoeologous gene pairs, examines regulation types basis bias. We analyzed four modifications (DNA methylation, H3K4me3, H3K27me3 H3K27ac) 29 976 pairs in resynthesized, natural allopolyploid Brassica napus an silico ‘hybrid’. comprehensively elucidated expression, generational ...

Combinatorial modifications of the core histones have the potential to fine-tune the epigenetic regulation of chromatin states. The Aurora B kinase is responsible for generating the double histone H3 modification tri-methylated K9/phosphorylated S10 (H3K9me3/S10ph), which has been implicated in chromosome condensation during mitosis. In this study, we have identified a novel role for Aurora B i...
