Abstract
KMT5C-mediated histone H4 lysine 20 trimethylation (H4K20me3) has traditionally been linked to heterochromatin formation and maintenance, playing a crucial role in maintaining genome integrity. Emerging evidence, however, indicates that perturbations of KMT5C-H4K20me3 are also implicated in various cancers, positioning KMT5C-H4K20me3 as a promising target for anti-cancer therapies. Despite this, the precise mechanisms underlying KMT5C recruitment to its genomic targets and the specific genes it regulates remain poorly understood. In this review, we explore the dysregulation of KMT5C-mediated H4K20me3 in cancer, providing a comprehensive overview of its known functions. We also highlight recent findings that suggest a novel, non-canonical pathway for H4K20me3 deposition by KMT5C, and, while early on, insight into future opportunities for therapeutic intervention.
期刊介绍：
Epigenetics publishes peer-reviewed original research and review articles that provide an unprecedented forum where epigenetic mechanisms and their role in diverse biological processes can be revealed, shared, and discussed.
Epigenetics research studies heritable changes in gene expression caused by mechanisms others than the modification of the DNA sequence. Epigenetics therefore plays critical roles in a variety of biological systems, diseases, and disciplines. Topics of interest include (but are not limited to):
DNA methylation
Nucleosome positioning and modification
Gene silencing
Imprinting
Nuclear reprogramming
Chromatin remodeling
Non-coding RNA
Non-histone chromosomal elements
Dosage compensation
Nuclear organization
Epigenetic therapy and diagnostics
Nutrition and environmental epigenetics
Cancer epigenetics
Neuroepigenetics
