GMFG and cancer: To better understand the potential function of GMFG in pan-cancers and to draw more attention to GMFG for the future cancer research, in this study, we investigated the clinical values of GMFG using The Cancer Genome Atlas (TCGA) data, and analyzed the underlying functional mechanisms of GMFG through conducting Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichments.
