TRIB3 and nonpapillary renal cell carcinoma: When the staining intensity of ccRCC patients stratified into groups with low or high levels of TRIB3 or PLIN2 expression, as determined based on median H-score values, low TRIB3 staining was confirmed to be associated with weaker PLIN2 staining in these tumors, while higher TRIB3 levels were associated with more intense PLIN2 staining (Fig. 8A–C).
