Epidermal Growth Factor Receptor (EGFR) mutants are associated with resistance to chemotherapy, radiation, and targeted therapies. Here we found that the phytochemical 3,3'-Diindolylmethane (DIM) can inhibit the growth and also the invasion of breast cancer, glioma, and non-small cell lung cancer cells regardless of which EGFR mutant is expressed and the drug-resistant phenotype. DIM reduced an array of growth factor signaling pathways and altered cell cycle regulators and apoptotic proteins favoring cell cycle arrest and apoptosis. Therefore, DIM may be used in treatment regimens to inhibit cancer cell growth and invasion, and potentially overcome EGFR mutant-associated drug resistance.
表皮生长因子受体(EGFR)突变与化疗、放疗和靶向治疗的耐药性有关。在这里,我们发现植物化学物质 3,3'-二吲哚甲烷(DIM)可以抑制乳腺癌、神经胶质瘤和非小细胞肺癌细胞的生长和侵袭,而不管表达哪种 EGFR 突变和耐药表型。DIM 减少了一系列生长因子信号通路,并改变了细胞周期调节剂和凋亡蛋白,有利于细胞周期停滞和凋亡。因此,DIM 可用于治疗方案,以抑制癌细胞生长和侵袭,并可能克服 EGFR 突变相关的耐药性。
