| I. Background | |
|
EGFR（Epidermal Growth Factor Receptor）是上皮生長因子（EGF）細(xì)胞增殖和信號 傳導(dǎo)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(xì)胞膜表面，靠與配體結(jié)合來激活。EGFR 與腫瘤細(xì)胞的增殖、血管生成、腫瘤侵襲、 轉(zhuǎn)移及細(xì)胞凋亡的抑制有關(guān)。
HER 受體通過與不同的配體結(jié)合而被激活，包括 EGF、TGFA、肝素結(jié)合 EGF 樣生長 因子、雙調(diào)蛋白、β細(xì)胞蛋白和上皮調(diào)節(jié)蛋白。配體與受體的細(xì)胞外結(jié)構(gòu)域結(jié)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(dǎo)酪氨酸激酶結(jié)構(gòu)域的激活，從而導(dǎo)致多個酪氨酸殘基上 的受體自磷酸化。從而導(dǎo)致一系列接頭蛋白（如 SHC、GRB2）的募集，并激活一系列細(xì) 胞內(nèi)信號級聯(lián)反應(yīng)以影響基因轉(zhuǎn)錄，進(jìn)而導(dǎo)致癌細(xì)胞增殖、減少細(xì)胞凋亡、侵襲和轉(zhuǎn)移， 并刺激腫瘤誘導(dǎo)的血管生成。 |
