PTGDR and breast cancer: Trastuzumab resistance is associated with the action of LncRNA OIP5-AS1 through miR-381-3p/HMGB3 axis [479], lncRNA ATB by competitively binding miR-200c, upregulating ZEB1 and ZNF-217, then inducing EMT [480], lncRNA AGAP2-AS1 by inducing BC cells autophagy [481], and lncRNA SNHG14 [482].
