表皮生长因子受体酪氨酸激酶抑制剂( EGFR-TKI)在非小细胞肺癌的治疗中具有重要地位,但有研究发现患者会对EGFR-TKI产生原发性耐药或获得性耐药。目前发现获得性耐药的多种机制最终都导致表皮生长因子受体的下游信号通路被重新激活。肝X受体激动剂对表皮生长因子受体最重要的下游通路PI3K-Akt-NF-κB的多个主要环节均有不同程度的抑制作用,有望逆转EGFR-TKI的继发耐药。
錶皮生長因子受體酪氨痠激酶抑製劑( EGFR-TKI)在非小細胞肺癌的治療中具有重要地位,但有研究髮現患者會對EGFR-TKI產生原髮性耐藥或穫得性耐藥。目前髮現穫得性耐藥的多種機製最終都導緻錶皮生長因子受體的下遊信號通路被重新激活。肝X受體激動劑對錶皮生長因子受體最重要的下遊通路PI3K-Akt-NF-κB的多箇主要環節均有不同程度的抑製作用,有望逆轉EGFR-TKI的繼髮耐藥。

EGFR-TKI plays an important role in the treatment of non-small-cell lung cancer. However, some researchers find that there are still some patients with primary or acquired resistance to EGFR-TKI. The present known mechanisms of acquired drug resistance finally lead to the re-activation EGFR downstream signa-ling pathways. Liver X receptor agonist has inhibition function to several critical steps of EGFR downstream sig-naling pathways PI3K-Akt-NF-κB,which makes it possible to overcome the drug resistance.
