1.神经退行性疾病与表观遗传调控
老年性痴呆(Alzheimer’s disease, AD)是一种神经退行性疾病,目前没有有效的治疗手段。全世界患有老年性痴呆的病人大约超过五千万人,中国目前正在进入老年型社会,患者急剧增加,给社会和家庭带来极大的负担。研究和理解老年性痴呆的发病机理,寻求一种有效的治疗手段成为现今最为迫切的社会需求。表观遗传学是在DNA序列不发生改变的情况下,基因的表达与功能发生改变,并产生可遗传的表型。表观遗传学机制对疾病发生发展起到了关键作用,尤其是散发性AD。表观遗传学调节障碍导致相关基因转录异常,引起关键蛋白功能或表达异常,继而发生一系列病理改变,可能是AD发病的主要原因之一。我们实验室主要研究AD病理以及大脑衰老过程中的组蛋白修饰改变,DNA甲基化,非编码RNA调控,染色体重塑等。
