Gene Regulation

Eukaryotic gene regulatory mechanisms that induce or repress the expression of a gene include structural and chemical changes to the chromatin and the DNA, binding of proteins to specific DNA elements, or mechanisms that modulate translation of mRNA.

Epigenetic mechanisms regulate many important biological processes during normal growth and development, and these mechanisms are deregulated in diseases such as cancer and diabetes.

Several techniques for characterizing the numerous regulatory and epigenomic modifications have been coupled with massively parallel sequencing strategies (NGS methods) to understand gene regulation. These include methods for characterizing interactions between protein, DNA, and RNA to survey transcription factor binding sites and histone modifications (ChIP-Seq), understand DNA methylation (Whole-Genome Bisulfite Sequencing (WGBS), Reduced Representation Bisulfite Sequencing (RRBS), Methylated DNA Immunoprecipitation Sequencing (MeDIP-Seq), understand DNA accessibility changes within the chromatin (ATAC-seq, FAIRE-seq, DNase-seq), chromatin conformation capture methods (3C, 4C, 5C, Hi-C), nucleosome occupancy and positioning (MNase-Seq, CC-Seq and ChIP-Seq), etc.
