SLC1A5 expression in clear-cell renal cell carcinoma (ccRCC) tissues and dichotomization of patients based on the cutoff of H-score.
(a) Representative immunohistochemical (IHC) images of ccRCC tissues with differential expression level of SLC1A5. Case 1 (H-score) = 0 × 69 (%) + 1 × 26 (%) + 2 × 5 (%) + 3 × 0 (%) = 36; Case 2 (H-score) = 0 × 22 (%) + 1 × 51 (%) + 2 × 27 (%) + 3 × 0 (%) = 105; Case 3 (H-score) = 0 × 8 (%) + 1 × 40 (%) + 2 × 32 (%) + 3 × 20 (%) = 164; Case 4 (H-score) = 0 × 0 (%) + 1 × 5 (%) + 2 × 41 (%) + 3 × 54 (%) = 249. Scale bar: 50 μm (original magnification × 200, × 400). (b) Dichotomization of patients based on the cutoff of H-score selected via “minimum P value” approach.
