ACTN1 and nonpapillary renal cell carcinoma: As shown in Figure 3, the high expression of TGFB1 (logrank p=0.00559), ICAM1 (logrank p=0.00419), TIMP1 (logrank p=1.44e-09), ACTN1 (logrank p=0.027) and VIM (logrank p=0.00978) predicted a poor prognosis for ccRCC patients, while the high expression of EGFR (logrank p=0.031), CCND1 (logrank p=0.000285) and VMF (logrank p=0.00399) predicted a favorable prognosis for ccRCC patients.
