Microtubule-associated serine-threonine (MAST) kinase is associated with gene rearrangement in breast cancer and related pre-invasive lesions [54], while Gene Set Enrichment Analysis (GSEA) indicated that NSUN4 was associated with methylation and demethylation processes in hepatocellular carcinoma [55]. This evidence concerns the gene NSUN4 and hepatocellular carcinoma.
