Expression characteristic of APOC1 in RCC. a Differential levels of APOC1 in a downloaded TCGA profile containing RCC tissues (n = 523) and normal tissues (n = 100); b Differential levels of APOC1 in stage I–IV RCC tissues in TCGA profile; c Overall survival in RCC patients based on high or low level of APOC1 in TCGA profile; d Differential levels of APOC1 in 20 pairs of RCC and adjacent non-tumoral tissues collected in our center; e Protein level of APOC1 in 20 paired cases of RCC and adjacent non-tumoral tissues (12 representative pairs were shown) (T: RCC tissues, N: adjacent non-tumoral tissues); f In vitro mRNA level of APOC1 in RCC cell lines; g Protein level of APOC1 in RCC cell lines; h The relative protein levels of APOC1 were examined by immunohistochemistry in a tissue microarray including 130 pairs of RCC tissues and normal tissues i Kaplan–Meier survival curves depicted based on APOC1 level in RCC patients. *P < 0.05, error bars indicate mean ± SD, t test
