转化生长因子(TGF)β是一族在细胞增殖、分化过程中起基本调节作用的激素样活性多肽，它包括五种异构体(TGFβ1－5)，TGFβ1是人体内的主要形式。TGFβ通过与细胞膜上的TGFβⅠⅣ型受体结合，发挥其各种细胞信号传递作用。TGFβ1和TGFβRⅡ的变化与多种肿瘤相关。本文检测了70 Transforming growth factor (TGF) β is a family of hormone-like active peptides that play a fundamental role in cell proliferation and differentiation. It includes five isomers (TGFβ1-5), and TGFβ1 is the main form in the human body. TGFβ exerts its various cell signaling functions by binding to TGFβIIV receptors on cell membranes. Changes in TGFβ1 and TGFβRII are associated with a variety of tumors. This article has detected 70
