Down-regulation of miR-27a could confer sensitivity of both P-glycoprotein-related and P-glycoprotein-non-related drugs on esophageal cancer cells, and might promote ADR-induced apoptosis, accompanied by increased accumulation and decreased releasing amount of ADR.
The purpose of the study was to investigate the change of drug-sensitivity and P-glycoprotein (P-gp) expression in ionization radiation-induced human esophageal cancer radioresistant cells.
We examined the ABCB1 gene polymorphism C3435T to predict response and prognosis to neoadjuvant radiochemotherapy (cisplatin, 5-fluorouracil and 36 Gy) in locally advanced esophageal cancer patients.
In conclusion, we propose that ABCB1 might play a pivotal role in acquisition of taxane resistance and could be a promising target for treatment of patients with esophageal cancer after acquisition of taxane resistance.
