袁国华教授团队在《Development》发表论文揭示SETD2调控牙本质生成的机制
近日,武汉大学口腔医学院袁国华教授课题组在发育学权威期刊《Development》发表题为“H3K36me3 modification by SETD2 is essential for Col11a2 and Sema3e transcription to maintain dentinogenesis in mice”的研究成果。《Development》创刊于1953年,是国际上发育生物学领域最具影响力的的经典老牌期刊之一,致力于发表动植物发育生物学领域的前沿研究。本论文第一作者为博士研究生牛佳欣,通讯作者为袁国华教授,在国家自然科学基金项目资助下完成。
牙本质是牙齿中含量最多的硬组织,对牙齿行使功能至关重要。在牙齿发育过程中,成牙本质细胞(odontoblasts)负责生成牙本质。本研究揭示了组蛋白甲基转移酶SETD2通过H3K36me3修饰,调控Col11a2和Sema3e基因转录,激活AKT1信号通路,从而维持成牙本质细胞分化及其功能。
近5年来,立足本土,袁国华教授课题组围绕牙齿发育调控机制发表多篇高质量论文,包括《Development》(3篇)、口腔医学领域权威期刊《Journal of Dental Research》(3篇)、自然指数期刊《Journal of Biological Chemistry》(3篇)、以及骨矿化领域权威期刊《Journal of Bone and Mineral Research》(1篇)等。
