For examples, LOC101930370/miR-1471 axis regulated breast cancer progression via the hedgehog signaling pathway [20]; LncRNA GAS5-MiR-23a-ATG3 axis regulated autophagy in breast cancer patients [21]; Linc00518 contributed to multidrug resistance through regulating the MiR-199a/MRP1 axis in breast cancer [22]; Downregulation of lncRNA GAS5 conferred tamoxifen resistance by activating miR-222 in breast cancer [23]; LncRNA ARNILA induced negatively by an androgen receptor bond to miR-204 and promoted the invasion and metastasis of triple-negative breast cancer [24]. This evidence concerns the gene GAS5 and breast cancer.
