MYC and squamous cell carcinoma: In agreement with these data, we have observed significant direct correlation between the expression of miR-145 and TΔRII, and c-Myc and miR-20, and inverse correlation between miR-145 and c-Myc, and miR-20a and TΔRII in both adenocarcinoma and squamous cell carcinoma using TCGA database (Fig. 1 and Fig. 8).
