The miR‐205‐3p expression in tumor tissues of breast cancer patients was significantly higher than that in para‐carcinoma tissue, but Ezrin, LaminA/C, and cleaved caspase‐3 expressions in tumor tissues were remarkably declined (P < 0.01), while the Bcl‐2/Bax ratio was remarkably increased (P < 0.01). Here, BAX is linked to breast carcinoma.
