遺伝子研究の概要
SUV39H2, also known as KMT1B, is a member of the SUV39 subfamily of lysine methyltransferases. It plays a significant role in histone H3-K9 di-/tri-methylation, transcriptional regulation, and cell cycle. Its activities are crucial for maintaining heterochromatin and gene repression, and it is involved in various biological processes [2,6].
In degenerated nucleus pulposus cells, SUV39H2-mediated K141 mono-methylation of PPP1CA disrupts TFEB-dependent autophagy, promoting intervertebral disc degeneration [1]. In trophoblast stem cells, SUV39H2 contributes to cell maintenance and restrains differentiation, and its disruption leads to cell proliferation arrest and differentiation activation [3]. In cardiomyocytes, knockdown of SUV39H2 accelerates senescence, while overexpression inhibits this phenotype, protecting cardiomyocytes from oxidative stress-induced damage through the p53-BTG2 pathway [4]. In gastric cancer, SUV39H2 promotes proliferation, inhibits apoptosis, and reduces chemosensitivity by promoting homologous recombination through epigenetic repression of DUSP6 [5]. In epidermal stem and progenitor cells, loss of SUV39H2 function relieves gene repression, enhancing Wnt activity and causing premature cell cycle exit [7]. Ablation of SUV39H2 in hepatocytes attenuates non-alcoholic steatohepatitis (NASH) in mice by regulating Vanin-1 transcription [8]. In osteosarcoma cells, knockdown of SUV39H2 suppresses cancer cell growth, viability, and induces apoptosis [9].
In summary, SUV39H2 is essential for multiple biological processes and is involved in various disease conditions. Through gene-knockout or conditional-knockout mouse models and other loss-of-function experiments, we have learned that SUV39H2 is implicated in diseases such as intervertebral disc degeneration, NASH, and several types of cancer, highlighting its potential as a therapeutic target in these disease areas.
