I. Background | |
EGFR(Epidermal Growth Factor Receptor)是上皮生長(cháng)因子(EGF)細胞增殖和信號 傳導的受體,EGFR 屬于 HER 受體家族,該家族由四種相關(guān)蛋白 EGFR(HER1/ErbB1)、 ERBB2(HER2)、ERBB3(HER3)和 ERBB4(HER4)組成,屬于酪氨酸激酶型受體, 位于細胞膜表面,靠與配體結合來(lái)激活。EGFR 與腫瘤細胞的增殖、血管生成、腫瘤侵襲、 轉移及細胞凋亡的抑制有關(guān)。
HER 受體通過(guò)與不同的配體結合而被激活,包括 EGF、TGFA、肝素結合 EGF 樣生長(cháng) 因子、雙調蛋白、β細胞蛋白和上皮調節蛋白。配體與受體的細胞外結構域結合后,受體形 成功能活性二聚體[EGFR-EGFR(同型二聚體)或 EGFR-HER2、EGFR-HER3、EGFR- HER4(異二聚體)]。二聚化誘導酪氨酸激酶結構域的激活,從而導致多個(gè)酪氨酸殘基上 的受體自磷酸化。從而導致一系列接頭蛋白(如 SHC、GRB2)的募集,并激活一系列細 胞內信號級聯(lián)反應以影響基因轉錄,進(jìn)而導致癌細胞增殖、減少細胞凋亡、侵襲和轉移, 并刺激腫瘤誘導的血管生成。 |
