IHC analysis of samples from the ccRCC tissue chip, which included 30 pairs of ccRCC tissues and matched peritumoral normal tissues, indicated that SGOL1 was highly expressed in ccRCC tissues compared with normal tissues (Fig. 1B), and a similar result was also observed in ccRCC cell lines (Fig. 1C, supplementary Fig. 2). Here, SGO1 is linked to nonpapillary renal cell carcinoma.
