MiR-200c is a PI3K–AKT signaling pathway regulator in CRC MiR-200c is a PI3K–AKT signaling pathway regulator in CRC. A, Western blot analyses of p-PI3K, T-PI3K, p-AKT, and T-AKT in the cells as indicated. MiR-200c is a PI3K–AKT signaling pathway regulator in CRC. A, Western blot analyses of p-PI3K, T-PI3K, p-AKT, and T-AKT in the cells as indicated. B, Western blot analyses of indicated proteins in SW480 and HCT116 knockdown of miR-200c, followed by the treatment of LY294002. GAPDH served as the loading control. C, proposed model of how miR-200c regulates CRC proliferation and metastasis through regulation of Sox2. Yan-Xia Lu et al.
