The negative correlation of mTOR and miR-99b-5p expression levels in colon, breast, and lung cancer cells indicated that the regulatory effects of the reciprocal pairing miR-99b-5p/mTOR (down/up) may play a crucial role in advanced colon, breast, and lung cancers, similar to what we observed in the AA PCa [15]. Here, MTOR is linked to lung carcinoma.
