摘要: Resistance to docetaxel (DTX) usually occurs in patients with lung adenocarcinoma. To better elucidate the underlying molecular mechanisms involved resistance DTX-based chemotherapy, we established a DTX-resistant adenocarcinoma cell line (SPC-A1/DTX). By gene array analysis, expression of ING4 was found be significantly downregulated SPC-A1/DTX cells. Additionally, decreased induced upon DTX treatment SPC-A1 Overexpression reverses or paclitaxel cells (SPC-A1/DTX A549/Taxol) by inducing apoptosis enhancement and G2/M arrest, small interfering RNA-mediated knockdown renders DTX-sensitive more resistant paclitaxel. Also, overexpression could enhance vivo sensitivity DTX. The phenotypical changes might associated ratio Bcl-2/Bax, which resulted activation caspase-3. level tumors nonresponding lower than that those responders, suggesting positively correlated tumor response Our results provide first evidence essential for Thus, will potential target overcoming chemotherapies
