马仙珏博士长期从事遗传学基础研究。课题组以黑腹果蝇作为主要模式生物,结合发育学,细胞生物学,生物化学与分子生物学等多学科,致力于揭示肿瘤发生过程中的信号传导及细胞内/间通讯的分子机制。在前期工作中,通过大规模遗传筛选,我们成功鉴定出了许多个JNK信号通路和Hippo信号通路的新成员,并初步揭示了其调控细胞凋亡,生长及肿瘤发生的分子机制。此外,我们还发现并命名包括FieryMountain(火焰山),Emei(峨眉) 在内的若干个新抑癌基因,并多次受美国果蝇遗传学会、亚太果蝇学会、日本发育生物学会等邀请做学术报告。现课题组主要研究方向主要包括(但不局限于)以下几个方面:
1.肿瘤发生的细胞间/内分子通讯机制。
2.新抑/致癌基因的遗传筛选与功能研究。
3.细胞竞争的机制研究。
