For instance, lncRNA KCNQ1 opposite strand/antisense transcript 1 was found to be overexpressed in BC tissues compared with normal bladder tissues and can promote cell proliferation, migration, invasion, and apoptosis via modulating the miR-218–5p/HS3ST3B1 axis (Li et al., 2020a). This evidence concerns the gene KCNQ1 and breast cancer.
