I. Background | |
EGFR(Epidermal Growth Factor Receptor)是上皮生长因子(EGF)细胞增殖和信号 传导的受体,EGFR 属于 HER 受体家族,该家族由四种相关蛋白 EGFR(HER1/ErbB1)、 ERBB2(HER2)、ERBB3(HER3)和 ERBB4(HER4)组成,属于酪氨酸激酶型受体, 位于细胞膜表面,靠与配体结合来激活。EGFR 与肿瘤细胞的增殖、血管生成、肿瘤侵袭、 转移及细胞凋亡的抑制有关。
HER 受体通过与不同的配体结合而被激活,包括 EGF、TGFA、肝素结合 EGF 样生长 因子、双调蛋白、β细胞蛋白和上皮调节蛋白。配体与受体的细胞外结构域结合后,受体形 成功能活性二聚体[EGFR-EGFR(同型二聚体)或 EGFR-HER2、EGFR-HER3、EGFR- HER4(异二聚体)]。二聚化诱导酪氨酸激酶结构域的激活,从而导致多个酪氨酸残基上 的受体自磷酸化。从而导致一系列接头蛋白(如 SHC、GRB2)的募集,并激活一系列细 胞内信号级联反应以影响基因转录,进而导致癌细胞增殖、减少细胞凋亡、侵袭和转移, 并刺激肿瘤诱导的血管生成。 |
