DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.
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,” ...
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 ...
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 ...
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 ...
Modification of histone tails, by acetylation, methylation or phosphorylation, affects the local chromatin structure and the transcriptional regulation of adjacent genes. Pericentric heterochromatin ...
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 ...
A new study has decoded how pea plants respond to salt stress through precise epigenetic reprogramming. Researchers created the first genome-wide map of four major histone modifications—H3K4me3, ...
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 ...
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, ...
