Chemical changes to histones, the proteins that help to pack and organize DNA inside cells, play a key role in determining what genes will be consistently activated over the course of an animal or ...

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 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 ...

Fruit ripening is a tightly coordinated process driven by both hormonal and environmental factors, yet the epigenetic mechanisms controlling this process remain unclear. Histone modifications, known ...

Histone modifications constitute a dynamic layer of epigenetic regulation that shapes gene expression programmes central to fungal virulence, morphogenesis and drug resistance. In pathogenic fungi ...

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,” ...

Dramatic epigenetic remodeling occurs during early embryonic development, leading to the formation of a totipotent embryo from terminally differentiated gametes 1,2. Epigenetic information plays a ...

Molecular biologists decode the epigenetic silencing of problematic retroviral gene sequences. LMU molecular biologist Gunnar Schotta decodes the epigenetic silencing of problematic retroviral gene ...

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 ...

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 ...
