Quantification results showed that the relative mRNA expression of TFE3 in both Xp11.2 tRCC cells and non‐Xp11.2 tRCC cell lines did not significantly change if AR was overexpressed or knocked down (Figure 2B). This evidence concerns the gene TFE3 and renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions.
