Every cell type in the human body carries the same approximately 3.2 billion base pairs of DNA, yet a liver cell behaves nothing like a neuron. The epigenome explains this difference: in each cell, ...

Histone modification is an epigenetic mechanism that regulates gene expression by altering chromatin structure and DNA accessibility for transcription. Histone modification is regulated by various ...

The accurate distribution of chromosomes in an oocyte is essential for the correct transmission of genetic information to the next generation. Now, researchers from Kyushu University have demonstrated ...

The immune system exhibits remarkable plasticity, enabling dynamic responses to environmental cues while maintaining tissue homeostasis. Emerging evidence ...

If all the DNA in a human cell was stretched out end to end, it would be roughly six feet long. That’s a lot of genetic information to pack into a cell that is, on average, one-fifth the size of a ...

New targeting discovery: Researchers found that DNA sequences can guide methylation machinery, a shift from the belief that ...

A picture of a mouse MII stage eggs with the location of chromosomes (green) and the distribution of the histone modification H3K4me3 (purple). The team confirmed that H3K4me3 was significantly ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...

LMU molecular biologist Gunnar Schotta decodes the epigenetic silencing of problematic retroviral gene sequences. While each cell contains the complete genetic blueprint of an organism, chemical marks ...

Epigenetics, the study of changes in gene function that do not involve alterations to the DNA sequence, plays a pivotal role in understanding the complex interplay between genetics and the environment ...
