FSTL1 and HIF-1α/2α levels in ccRCCs and adjacent tissues and their effects on postoperative prognosis. a–c Representative immunostaining of FSTL1, HIF-1α, and HIF-2α in adjacent renal tissues, respectively. The HIF-2α positive parts are indicated by black arrows. d–f Representative immunostaining of FSTL1, HIF-1α, and HIF-2α in ccRCC tissues, respectively. g–i Effect of intratumoral expression of FSTL1, HIF-1α, and HIF-2α on disease-specific survival, respectively
