IF staining demonstrated cytoplasmic co‐localization of USP10 and FMR1 in ccRCC cells (Figure 6I), which was further supported by Co‐IP (Co‐immunoprecipitation) assays confirming an endogenous USP10–FMR1 interaction (Figure 6J). This evidence concerns the gene FMR1 and nonpapillary renal cell carcinoma.
