HSPA8 and renal pelvis urothelial carcinoma: The levels of HSC70 transcripts were elevated 1.562-fold in papillary renal cell carcinoma samples compared to those in normal tissues in a dataset containing 11 samples derived from the Jones study (P = 1.93×10-7; Supplementary Figure 1A) and elevated 1.413-fold in renal pelvis urothelial carcinoma samples compared to those in normal tissues (P = 1.95×10-4; Supplementary Figure 1B).
