研究方向
本实验室主要研究哺乳动物卵巢功能的分子调节机理以及卵巢相关疾病的发生机理。
卵巢作为雌性生殖器官,其功能主要是产生成熟的雌性生殖细胞(卵母细胞)并分泌性激素。哺乳动物卵巢主要由处于不同发育阶段的卵泡和黄体组成。卵泡的发育、排卵和黄体化受到两种促性腺激素FSH和LH的紧密调控。我们利用多种卵泡颗粒细胞或卵母细胞特异性的基因敲除小鼠和转基因小鼠,研究促性腺激素激活的信号通路及其靶基因对卵巢功能的调节作用。我们最近的研究揭示,PI3K/AKT信号通路参与调节颗粒细胞增殖或凋亡,而RAS/ERK1/2信号途径是LH诱导卵母细胞成熟、排卵和黄体化过程所必需的。通过基因芯片分析,我们鉴定出了小鼠基因组中所有在排卵过程中受到LH调节的基因,并进一步确定了哪些LH靶基因的表达依赖于RAS/ERK1/2信号通路的激活。在进一步的研究中,我们将继续分析这些新发现的LH靶基因在卵巢中的功能,以及其他重要信号通路对卵泡发育和排卵的调节作用。
当这些调节卵巢正常功能的信号分子发生遗传缺失或过度激活,就会导致各种卵巢疾病,比如卵巢早衰、多囊卵巢综合症和卵巢肿瘤。本实验室也将综合利用转基因小鼠模型和人类临床样本,研究重要基因和信号通路在这些卵巢疾病发生中的作用。
上述工作,不仅可以推动哺乳动物生殖与发育生物学的基础研究,也在医学临床实践(如辅助生殖、计划生育、内分泌疾病和卵巢癌的治疗)、经济动物养殖和珍稀野生动物保护等领域具有重要的理论指导作用。
Research interests:
My major research interest is to dissect the signaling pathways and their target genes that regulate the ovarian functions in mammalian species.
Ovary is the female reproductive organ that produces fertilizable female germ cells (oocytes) and sexual hormones. Follicle development, ovulation and luteinization are tightly regulated by follicle-stimulating hormone (FSH) and luteinizing hormone (LH). I have generated multiple granulosa cell or oocyte-specific gene knockout and transgenic mouse models, to dissect the gonadotropin-activated signaling pathways and their target genes that regulate the ovarian functions. My recent studies have shown that the PI3K/AKT pathway is involved in the regulation of granulosa cell proliferation and apoptosis, whereas EGF receptor/RAS/ERK1/2 cascade is essential for LH-induced oocyte maturation, ovulation and luteinization. By microarray analysis, I have identified numerous LH regulated genes during ovulation, and determined which of them are under the control of RAS/ERK1/2 cascade. We will continue to investigate the functions of these novel LH target genes in the mammalian ovaries, as well as other signaling molecules involved in follicle development and ovulation.
While the precisely regulated signaling events maintain the normal ovarian functions, the aberrant expressions or activations of essential signaling molecules lead to ovarian disorders such as premature ovarian failure (POF), polycystic ovarian syndrome (PCOS) and ovarian cancers. I will also study several conditional mutant mouse strains that develop ovarian cancers (both granulosa cell tumors and ovarian surface epithelial tumors) in addition to reproductive defects.
These studies will not only contribute to the basic research of mammalian reproductive biology, but also have potentials of wide application in human clinics (i.e. contraception, assistant reproduction, therapies of endocrine disease and ovarian cancers), farm animal reproduction, and genetic conservation of endangered mammalian species.
