TLDR
Results reveal a novel function of baicalin in inducing growth arrest of PDGF-stimulated VSMCs and suppressing neointimal hyperplasia after balloon injury, and suggest that the underlying mechanism involves the inhibition of cyclin E-CDK2 activation and the increase in p27 accumulation via blockade of the PDGFRβ-ERK1/2 signaling cascade.
Abstract
脉管的光滑的肌肉房间(VSMC ) 的增加的增长和移植是在动脉粥样硬化患者损害的开发的关键事件。Baicalin,导出植物的 flavonoid 混合物,以前被显示了通过多重小径在癌症房间导致 apoptosis 和生长抑制。然而,在 VSMC 增长和心血管的疾病的预防的规定的 baicalin 的潜在的角色仍然保持未经勘探。在这研究,我们证明有 baicalin 的那个预告的处理有一个剂量依赖者 PDGF-BB-stimulated VSMC 增长上的禁止的效果,与增殖的减小伴随了房间原子抗原(PCNA ) 表示。我们也证明导致 baicalin 的生长抑制在在 p27 的激活和增加在刺激 PDGF 的 VSMC 铺平的 cyclin E-CDK2 与减少被联系,它看起来是部分至少由 PDGF 受体尾的封锁调停了(PDGFR 尾) 发信号的细胞外的调整信号的 kinase 1/2 (ERK1/2 ) 。另外, baicalin 也被发现禁止 PDGF-BB 在 VSMC 导致的粘附分子表达式和房间移植。而且,使用一根动物颈动脉动脉的汽球损害模型,我们发现 baicalin 显著地禁止了 neointimal 增生。一起拿,我们的结果在导致生长揭示 baicalin 的新奇功能在汽球损害以后刺激 PDGF 的 VSMC 和压制的 neointimal 增生逮捕,并且建议内在的机制经由 PDGFR 尾 - 的封锁包含在 p27 累积的 cyclin E-CDK2 激活和增加的抑制 ERK1/2 发信号串联。

Baicalin attenuates chronic hypoxia-induced pulmonary hypertension via adenosine A 2A receptor-induced SDF-1/CXCR4/PI3K/AKT signaling.

TL;DR: Baicalin exerts protective effects against clinical HPH, which are partly mediated through enhanced A2AR activity and down-regulated SDF-1/CXCR4-induced PI3K/AKT signaling.

Cancer Cell Cycles

TL;DR: Genetic alterations affecting p16INK4a and cyclin D1, proteins that govern phosphorylation of the retinoblastoma protein and control exit from the G1 phase of the cell cycle, are so frequent in human cancers that inactivation of this pathway may well be necessary for tumor development.

Translational control of p27Kip1 accumulation during the cell cycle.

TL;DR: In every instance investigated, the posttranscriptional alteration of p27 protein levels was achieved in part by a mechanism of translational control, although in density-arrested fibroblasts and thymidine-ar Arrested HeLa cells the half-life of the protein was also changed.
