CDK6 is an oncogenic kinase regulating the cell cycle. In this issue of Cancer Cell, Kollmann and colleagues demonstrate that CDK6 performs a kinase-independent transcriptional function in regulating expression of VEGF-A and p16INK4a. These observations link the cell cycle machinery and angiogenesis and reveal the presence of a fail-safe antiproliferative mechanism.
CDK6 是一种致癌激酶,调节细胞周期。在本期《癌细胞》中,Kollmann 及其同事证明 CDK6 通过激酶非依赖性的转录功能调控 VEGF-A 和 p16INK4a 的表达。这些观察结果将细胞周期机制与血管生成联系起来,并揭示了存在一种故障安全的抗增殖机制。
