Summary of Epigenetic Databases

Science’s understanding of genetics primarily focuses on the alterations in gene expression caused by genetic sequence modifications, encompassing gene mutations, heterogeneous loss, and microsatellite instability. Contrastingly, epigenetics considers the changes in gene expression attributable to non-genomic sequence variations, such as DNA methylation and modifications in chromatin conformation. The broader field of epigenomics is dedicated to the genomic […]

Utilizing ATAC-Sequencing Approach to Predict Transcription Factors Binding in Individual Cells

Introduction to Transcription Factors Molecules important in controlling gene expression are transcription factors. Normally they are proteins, although they are composed of short, non-coding RNA as well. Transcription variables are also typically seen working in groups or complexes, creating multiple connections that allow varying degrees of control over transcription rates. Transcription factors (TFs) attach to […]

Epigenetics Sequencing Methods for Bacterial Methylation Sequencing

DNA methylation, histone variant, histone modifications, and nucleosome positioning are pathways for epigenetic regulation in eukaryotes. Bacteria, on the other hand, lack histones and nucleosomes; hence, they primarily use DNA methylation as their epigenetic gene regulation. There are three different types of DNA methylation in bacterial genomes: N4-methylcytosine (4mC), N6-methyladenine (6mA), and 5-methylcytosine (5mC). The […]

RIP-Seq vs. CLIP-Seq: Introduction, Advantages, and Applications

The protein translation is a complicated process. In the past decades, scientists have focused mainly on the interpretation of the coding region of a gene, which can directly determine the amino acid composition of a protein. Recently, research on the non-coding RNA (ncRNA) regions have greatly interested the scientists and large amount of evidence indicates […]

What Is DNA Methylation

Not all genes are active at all times. DNA methylation is a common epigenetic modification used by cells to regulate gene expression. In recent decades, researchers have discovered that methylation is involved in many cellular processes, including genomic imprinting, embryonic development, gene suppression, carcinogenesis, X-chromosome inactivation, and preservation of chromosome stability. And abnormal DNA methylation […]

A Brief Introduction on DNA Methylation and Methods of Detection

Except DNA and RNA, there are many messages which will affect the gene expression in genome. They do not change the sequence, but have the power of regulation on function and characteristics of gene by chemical modification, RNA interference and the interaction between protein and DNA. This change will be passed to the next generation. […]
