TP53INP2 and renal cell carcinoma: In addition, among the 6 genes that have been predicted to be targeted by miR-34a via the in silico computational tools, two genes were significantly upregulated (MET and E2F3) in 87.1% of FFPE samples, while two others were downregulated (TP53INP2 and SOX2) in almost all RCC patients compared to noncancer tissues (Figure 3).
