Using the “Pathological Stage Plot” module of GEPIA2, we also found that the expression of CARM1 is related to the pathological stages of the following carcinomas, comprising ACC (adrenocortical carcinoma), ESCA, KICH and UCS (uterine carcinosarcoma) (Fig. 4a, all P < 0.05), but no significant difference is observed in other tumors (Fig. S3, see Additional file 3). This evidence concerns the gene CARM1 and adrenal cortex carcinoma.
