Since linc‐ROR could downregulate the expression of miR‐194‐3p which functions as a tumor suppressor miRNA, and the rescue of miR‐194‐3p expression in LV‐linc‐ROR reduced the promoting effect of linc‐ROR, we concluded that linc‐ROR promoted the proliferation, migration, and invasion of breast cancer cells by functioning as a ceRNA sponge for miR‐194‐3p. This evidence concerns the gene LINC-ROR and breast cancer.
