The overexpression or knockdown of maspin can affect the sensitivity of lung cancer cells to docetaxel. Fluorescence qPCR (A) and western blot (B) were used to detect the overexpression of maspin in the lung adenocarcinoma-resistant cell line, SPC-A1/docetaxel (DTX). Fluorescence qPCR (C) and western blot (D) were used to detect the interference efficiency of the lung adenocarcinoma sensitive cell line, SPC-A1, after maspin interference. (E) The MTT assay was used to detect the influence of lung adenocarcinoma drug-resistant cell lines and parent cell lines with maspin overexpression or knockdown on IC50 values of DTX, DDP, and Gem. **, P<0.01.
