LDHA and breast cancer: To determine the roles of lncRNAs in regulating chemoresistant breast cancer stem cell properties, we generated paclitaxel (PTX)-resistant MDA-MB-231 BCSC (ALDH+) and non-BCSC (ALDH−) using fluorescence-activated Cell Sorting (FACS) (Supplementary Fig. 1a, b) as previously described [29] and then lncRNA RNA-sequencing was performed.
