FIS1 and cancer: The analysis of mRNA functions in the network revealed that although most of the mRNAs with the strongest correlation with miRNAs were also related to cancer and tumorigenesis, these mRNAs were more specifically related to glucose metabolism and oxidative phosphorylation (MRPL28, ALDH1L2, ECI1, PDP2) and mitochondrial dynamics (TIMM8A, MTFP1, Fis1, ErbB).
