However, after the adjustment two potential biomarkers were found: inactivation of sodium-dependent transport of (i) phosphate, supported by SLC17A1 and (ii) ascorbate supported by SLC23A1. Inactive phosphate and ascorbate transport characterized, respectively, 65 and 62 out of 66 ChRCC samples; 45 and 28 out of 774 other tumor samples. Here, SLC23A1 is linked to chromophobe renal cell carcinoma.
