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,” ...

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 ...

EpiciphAI公司正研发一款液体活检产品，通过检测无细胞染色质上的组蛋白标记，确定染色质片段的组织来源，并区分该组织中与疾病相关的状态。目前该公司仍处于种子前阶段，其技术的首个应用场景为难以进行活检的组织的癌症诊断与病情监测。

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

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, ...

Diagram depicting all histone modifications, mutants, and variants present in the 115-member nucleosome library used in this study. Residues modified or mutated were mapped on to the nucleosome in ...

Researchers discovered that a small region of the PRC2 protein complex acts as a functional switch controlling gene silencing ...

Cancers emerge from many different paths. One path begins early, in embryonic development, when a protein complex called PRC2 ...
