Lnc KCNQ1OT1 and MDR1 level were highly expressed in DOX-resistant BC cells, while miR-103a-3p level was lowly expressed. Note: a, IC50 values of BC cells and DOX-resistant BC cells were determined by MTT. b, cell proliferation was detected using clone formation. c, the apoptosis rate was measured with flow cytometry. d, lnc KCNQ1OT1, miR-103a-3p, and MDR1 expression was tested using qRT-PCR. e, western blot was performed to measure MDR1 expression.
