I. Background | |
EGFR(Epidermal Growth Factor Receptor)是上皮生長(zhǎng)因子(EGF)細(xì)胞增殖和信號(hào) 傳導(dǎo)的受體,EGFR 是一種糖蛋白,,屬于激酶型受體,,位于細(xì)胞膜表面,,靠與配體 結(jié)合來(lái)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),。EGFR 基因突變是預(yù)測(cè) NSCLC 患者使用 EGFR-TKIs 療效的重要靶標(biāo),。 | |
II. Background | |
BaF3(小鼠原 B 細(xì)胞)的生長(zhǎng)和增殖需要 IL-3 的維持,。通過(guò)引入各種表達(dá)激酶的基因,, 能作為 BaF3 的驅(qū)動(dòng)基因,,讓 BaF3 不再依賴(lài) IL-3 而增殖,進(jìn)而激酶基因成為 BaF3 增殖依 賴(lài)的驅(qū)動(dòng)基因,,用于評(píng)估小分子藥物對(duì)激酶的靶向抑制作用,,原理及流程見(jiàn)下圖所示。
