SOD2 and colorectal carcinoma: As with SOD2 expression, the hsa-miR-324-5p expression data for CRC in the PANCANCER cohort was consistent with data obtained from analysis of the TCGA CRC dataset (n = 325), with a markedly down-regulated hsa-miR-324-5p expression level in the CRC compared to the non-tumor colorectal tissues (~0.26-fold, p = 1.03 × 10−13) (Figure 1D).
