SLC12A7 and cancer: Given the limited understanding of SLC12A7 in oncogenesis and the urgent need for novel biomarkers, particularly in hepatocellular carcinoma (HCC), we conducted a comprehensive pan-cancer analysis to elucidate its potential oncogenic roles.<h4>Methods</h4>Transcriptomic and clinical data from The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx), cBioPortal, TIMER 2.0, and Gene Expression Omnibus (GEO) were integrated to investigate the expression patterns, prognostic significance, genetic alterations, and immune correlations of SLC12A7.
