It was observed that overexpression of miR‐409‐3p sensitizes CRC cells to OXA and restrains chemotherapy‐induced autophagy in a manner that depends on Beclin 1, suggesting that miR‐409‐3p is able to enhance the chemosensitivity of CRC cells by inhibiting Beclin 1‐mediated autophagy.55 The gene discussed is BECN1; the disease is colorectal carcinoma.
