研究领域（Research Area)
我们围绕核受体特别是核孤儿受体TR3（也被称为Nur77或NGFI-B）的生物学功能开展研究。TR3在细胞生长、分化、凋亡等过程中发挥着至关重要的作用。由于其特异性配体至今尚未被发现，TR3的翻译后修饰以及其相互作用蛋白被认为是调控TR3生物学功能的重要方式。我们的研究发现TR3可通过对Wnt信号通路的负调控作用，抑制结肠癌的发生。在结肠癌临床标本中，高活性的GSK3β介导TR3发生高度磷酸化，从而阻断了TR3对Wnt信号的抑制作用，导致结肠癌的发生。此外，Akt, ERK, Pin1等介导的TR3翻译后修饰也直接影响TR3对细胞生长和凋亡的调控作用。
我们将继续以胃癌、肠癌、肝癌等消化系统肿瘤以及肥胖、糖尿病、高血脂等代谢综合症为研究重点，深入阐明TR3通过对细胞代谢、细胞自噬、细胞凋亡等的调控影响疾病发生的机制，并以TR3为靶点筛选干预这些疾病发生的小分子药物。
We mainly focus on the biological functions of nuclear receptor, especially orphan nuclear receptor TR3 (also known as Nur77 or NGFI-B). TR3 plays an important roles in the processes of cell proliferation, differentiation and apoptosis. Since the specific ligand for TR3 has not been identified till now, the post-translational modifications of TR3 and its binding partners were considered as the main regulatory manner for TR3. We found that TR3 can inhibit growth of colorectal cancer via negatively regulating Wnt singaling activity. In colorectal cancer tissues, highly activated GSK3β induces hyper-phosphorylation of TR3, thereby disrupting the inhibitory effect of TR3 on Wnt signaling and stimulating the tumorigenesis of colorectal cancer. Moreover, Akt, ERK and Pin1 mediated post-translational modifications also influence the regulatory functions of TR3 on cell proliferation and cell death.
We will go on studying the functions of TR3 on digestive system cancer and metabolic syndrome through the regulation on cell metabolism, autophagy and apoptosis, and screening TR3 targeting compounds to interfere the development of this disease.
