全反式维甲酸(atRA)是维生素A的活性成分之一,通过核RA受体(RARs)介导的基因表达调控发挥典型的活性。AtRA还能引起某些非经典的活性,主要包括细胞外信号调节激酶1/2(ERK 1/2)的快速激活,但其机制尚不清楚。在这项研究中,我们已经发现,细胞视黄酸结合蛋白I(CRABPI)介导的非典型的,RAR和膜信号的非依赖性激活ERK 1/2的atRA在各种细胞背景。在胚胎干细胞(ESC)的背景下,atRA/CRABPI依赖性ERK 1/2激活迅速影响ESC细胞周期,特别是扩大G1期。这是由ERK刺激介导的,导致核p27的去磷酸化,从而提高核p27蛋白水平以阻断G1期进展到S期。这是第一个研究,以确定CRABPI作为介质的非经典激活ERK 1/2的atRA,并证明了一个新的功能作用,CRABPI在调节ESC细胞周期进程。
All-trans retinoic acid (atRA), one of the active ingredients of vitamin A, exerts canonical activities to regulate gene expression mediated by nuclear RA receptors (RARs). AtRA could also elicit certain non-canonical activities including, mostly, rapid activation of extracellular signal regulated kinase 1/2 (ERK1/2); but the mechanism was unclear. In this study, we have found that cellular retinoic acid binding protein I (CRABPI) mediates the non-canonical, RAR- and membrane signal-independent activation of ERK1/2 by atRA in various cellular backgrounds. In the context of embryonic stem cells (ESCs), atRA/CRABPI-dependent ERK1/2 activation rapidly affects ESC cell cycle, specifically to expand the G1 phase. This is mediated by ERK stimulation resulting in dephosphorylation of nuclear p27, which elevates nuclear p27 protein levels to block G1 progression to S phase. This is the first study to identify CRABPI as the mediator for non-canonical activation of ERK1/2 by atRA, and demonstrate a new functional role for CRABPI in modulating ESC cell cycle progression.
