袁國華教授團隊在《Development》發表論文揭示SETD2調控牙本質生成的機制
近日,8858ccl8利网址口腔醫學院袁國華教授課題組在發育學權威期刊《Development》發表題為“H3K36me3 modification by SETD2 is essential for Col11a2 and Sema3e transcription to maintain dentinogenesis in mice”的研究成果。《Development》創刊于1953年,是國際上發育生物學領域最具影響力的的經典老牌期刊之一,緻力于發表動植物發育生物學領域的前沿研究。本論文第一作者為博士研究生牛佳欣,通訊作者為袁國華教授,在國家自然科學基金項目資助下完成。
牙本質是牙齒中含量最多的硬組織,對牙齒行使功能至關重要。在牙齒發育過程中,成牙本質細胞(odontoblasts)負責生成牙本質。本研究揭示了組蛋白甲基轉移酶SETD2通過H3K36me3修飾,調控Col11a2和Sema3e基因轉錄,激活AKT1信号通路,從而維持成牙本質細胞分化及其功能。
近5年來,立足本土,袁國華教授課題組圍繞牙齒發育調控機制發表多篇高質量論文,包括《Development》(3篇)、口腔醫學領域權威期刊《Journal of Dental Research》(3篇)、自然指數期刊《Journal of Biological Chemistry》(3篇)、以及骨礦化領域權威期刊《Journal of Bone and Mineral Research》(1篇)等。
