TGFbetasignalingpathway
TGF-beta regulates growth and proliferation of cells, blocking growth of many cell types. The TGF-beta receptor includes type 1 and type 2 subunits that are serine-threonine kinases and that signal through the SMAD family of transcriptional regulators. Defects in TGF-beta signaling, includes mutation in SMADs, have been associated with cancer in humans. Prior to activation, receptor regulated SMADs are anchored to th......阅读全文

TGFbeta信号通路研究背景
TGF-β信号传导参与许多细胞（包括胶质瘤细胞）的增殖、分化和存活/或凋亡的调节。TGF-β通过特异性受体激活多种细胞内途径发挥作用，导致受体调节的Smad2/3蛋白磷酸化，这些蛋白与共同的介体Smad4相关。这种复合物易位到细胞核，与DNA结合并调节许多基因的转录。此外，TGFβ活化激酶-1（TA
PNAS：TGFbeta信号能够抑制子宫癌的发生
最近，贝勒医学院的研究人员发现，子宫细胞中的转化生长因子β（TGF-β）信号通路通过抑制子宫内膜的过度生长和转化抑制子宫癌的发生。该研究结果发表在今天的《PNAS》的两篇论文中，提出了可能对患者有益的新治疗策略。 “TGF-β信号通路调节了许多类型癌症的发展，但尚不清楚它是否也在子宫癌的发展中
