卵泡抑素相关蛋白的病理生理功能

Pathophysiological Functions of Follistatin Related Protein

卵泡抑素相关蛋白(follistatin related protein,FRP)是一种细胞外基质糖蛋白,该蛋白参与细胞增殖、迁移、组织重塑、胚胎发育、细胞间相互作用及多种病理生理过程。近年研究显示,该蛋白同时具有抑制细胞凋亡和抑制细胞增殖的双重功能:在心肌缺血的动物模型中,FRP被证实有保护心肌细胞、抗凋亡、促进内皮细胞增殖等功能;FRP也可由血管平滑肌细胞合成分泌,并具有反馈调节平滑肌细胞功能的作用,该蛋白还可抑制多种肿瘤细胞增殖。

Follistatin related protein （FRP） is an extra-cellular glyeoprotein, involved in several pathological and physiological processes such as cell proliferation, migration, tissue remodeling, embryonic development, and cell-cell interaction. Nowadays researches showed that FRP possesses dual functions, including inhibiting cell apoptosis and inhibiting cell proliferation. In myocardial ischemia model, FRP is certified to have the effect of protecting myocardial cell and inhibiting apoptosis. At the same time FRP promotes endothelial cell proliferation. FRP is also synthesized by vascular smooth muscle cell （VSMC） to regulate the functions of VSMC via feedback mechanism. FRP can induce apoptosis in various cancer cell lines. In this review, we summarized the up-to-date data to show the structure, functions, mechanisms and regulation pathways of the protein.
