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 ...

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.

Strands of DNA wrapped around a histone. Credit: Molekuul/Science Source Histones are among the most abundant proteins in the body. They act as spools that help compact DNA so our enormous genomes ...

Histone modification is an epigenetic mechanism that enables fine-tuning of gene expression. Mutation or dysregulation of proteins associated with histone modification (called “writers,” “erasers,” ...

Modification of histone tails, by acetylation, methylation or phosphorylation, affects the local chromatin structure and the transcriptional regulation of adjacent genes. Pericentric heterochromatin ...

Researchers have determined whether a specific chemical modification of a protein that packages the genome called a histone affects gene activity and cell proliferation. Researchers have determined ...

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 ...

Epigenetics is rewriting what we know about how our genes work, adapt, and sometimes fail. From chemical tags that switch genes on or off to RNA molecules that fine-tune expression, scientists are ...

Plants don’t just react to stress — some can ‘remember’ it through epigenetic changes that influence how future generations respond. This stress memory, often mediated by changes in DNA methylation, ...
