Fig. 3From: Blockage of AMPK-ULK1 pathway mediated autophagy promotes cell apoptosis to increase doxorubicin sensitivity in breast cancer (BC) cells: an in vitro studyInhibition of autophagy by 3-MA aggravated the promoting effects of high-dose doxorubicin-induced cell death in DR-BC cells. a, b Cell proliferation was evaluated by CCK-8 assay. c, d Colonies formation abilities were examined by colony formation assay. e Trypan blue staining assay was performed to determine cell viability. f, g Cell apoptosis was determined by using the Annexin V-FITC/PI double staining method. Each experiment repeated at least 3 times, and *P < 0.05 was regarded as statistical significanceBack to article page
