Chronic hepatitis B (CHB) remains a global health dilemma with high morbidity and mortality. Human males absent on the first (hMOF) (a histone acetyltransferase) is responsible for DNA damage repair, tumorigenesis and cell cycle regulation. Persistence of HBV DNA contributes to cirrhosis and hepatocellular carcinoma (HCC) in CHB patients. Histone acetyltransferase enhances HBV replication, however the precise underlying mechanism of hMOF in HBV replication in CHB patients remains to be explored. This study aims to investigate the correlation between hepatic hMOF and HBV DNA replication in CHB patients, and may provide new insights towards the treatment of CHB patients.
hMOF in liver biopsy (CHB, n = 33 HBeAg; n = 20 HBeAg, and three healthy controls) was determined, using immunohistochemistry, qPCR and Western blot. The correlation between hMOF and HBsAg, as well as, HBeAg were determined.
A positive correlation between hMOF and HBV DNA in overall CHB patients was observed. A distinct positive correlation between hMOF and HBsAg and/or HBeAg in HBeAg CHB patients was also detected, however not observed between hMOF and HBsAg in HBeAg CHB patients. No correlation was observed between hMOF and hepatic inflammation severity and fibrotic stage in CHB patients.
Hepatic hMOF might contribute to host HBV clearance in CHB patients and possible pathogenesis.
慢性乙型肝炎(CHB)仍然是一个全球性的健康难题,发病率和死亡率都很高。人类一号染色体上缺失的雄性蛋白(hMOF)(一种组蛋白乙酰转移酶)负责DNA损伤修复、肿瘤发生和细胞周期调控。HBV DNA的持续存在会导致CHB患者发生肝硬化和肝细胞癌(HCC)。组蛋白乙酰转移酶可增强HBV复制,然而,hMOF在CHB患者HBV复制中的确切潜在机制仍有待探索。本研究旨在探讨CHB患者肝脏hMOF与HBV DNA复制之间的相关性,并可能为CHB患者的治疗提供新的见解。
采用免疫组织化学、qPCR和蛋白质免疫印迹法测定肝活检组织中的hMOF(CHB患者,HBeAg阳性33例;HBeAg阴性20例,以及3例健康对照)。确定hMOF与HBsAg以及HBeAg之间的相关性。
观察到总体CHB患者中hMOF与HBV DNA呈正相关。在HBeAg阳性CHB患者中也检测到hMOF与HBsAg和/或HBeAg之间存在明显的正相关,然而在HBeAg阴性CHB患者中未观察到hMOF与HBsAg之间的相关性。CHB患者中hMOF与肝脏炎症严重程度和纤维化分期之间未观察到相关性。
肝脏hMOF可能有助于CHB患者体内HBV的清除以及可能的发病机制。
