SLC7A11 and colorectal carcinoma: Wang et al. found that overexpression of circCOL5A1 in CRC was related to the adverse prognosis of CRC patients, and further mechanistic studies showed that circCOL5A1 inhibited ferroptosis of CRC cells through miR-1287-5p/SLC7A11 axis, thus promoted CRC cell proliferation and invasion [183].
