杨巍维:丙酮酸激酶M2亚型在EGFR促进的癌症发生中的作用及机制

肿瘤细胞,即使在氧气充足的情况下,仍倾向于利用糖酵解的方式代谢葡萄糖,在摄取大量葡萄糖的同时排出大量的乳酸,这个现象被称为“Warburg效应”。可以肯定的是,糖酵解赋予了肿瘤细胞独特的生长优势,但这种优势形成的内在机制仍不清楚。

有研究认为,肿瘤细胞利用大部分葡萄糖代谢中间产物合成生物大分子(氨基酸,核酸以及磷脂),从而支持肿瘤细胞的快速生长。我们的研究则发现糖酵解以另外一种全新机制赋予肿瘤细胞生长优势。

本报告将以丙酮酸激酶M2(PKM2)为切入点,围绕细胞核内PKM2的功能,着重探讨了PKM2的“非代谢”功能在癌症发生、发展中的作用及机制。

蛋白激酶的结构 - Susan Taylor

In this lecture, I have given an overview of protein kinase structure and function using cyclic AMP dependent kinase (PKA) as a prototype for this enzyme superfamily. I have demonstrated what we have learned from the overall structural kinome which allows us to compare many protein kinases and also to appreciate how the highly regulated eukaryotic protein kinase has evolved. By comparing many protein kinase structures, we are beginning to elucidate general rules of architecture. In addition, I have attempted to illustrate how PKA is regulated by cAMP and how it is localized to specific macromolecular complexes through scaffold proteins.
