The correlation between the mRNA levels of FABP1, PDZK1 and T, M stage, recurrence, tumor maximum diameter and weight.
(a) FABP1 mRNA level was obtained from TCGA_KIRC dataset and the trend of expression level with the increase of T stage was analyzed by ANOVA. The differences of FABP1 mRNA level between ccRCC patients without and with distant metastasis, recurrence were analyzed by independent sample t-test. (b) PDZK1 mRNA level was obtained from TCGA_KIRC dataset and the trend of expression level with the increase of T stage was analyzed by ANOVA. The correlations of PDZK1 mRNA level with tumor volume, maximum diameter and weight were analyzed by Pearson correlation analysis. PDZK1 protein level was obtained from IHC of 112 cases. The correlations of PDZK1 protein level with tumor maximum diameter was analyzed by Pearson correlation analysis.
