Furthermore, an exploration of SLC16A3 protein expression levels, conducted using the UALCAN database and immunohistochemistry data from the HPA database, revealed significant overexpression of SLC16A3 protein in ccRCC, BRCA, COAD, HNSC, HCC, GBM, LUAD, PAAD, and UCEC. Here, SLC16A3 is linked to nonpapillary renal cell carcinoma.
