Identification of RCC antigen PARG1 by SEREX and expression of PARG1 mRNA in normal kidney, RCC tissues, and RCC cell lines.

(A) Presence of anti-PARG1 IgG from sera of RCC was detected by Western blot analysis with recombinant His-tagged PARG1 protein. Detection samples are shown in red. (B) Frequent detection of anti-PARG1 IgG in sera from patients with RCC was evaluated by ELISA. ELISA was done with the recombinant PARG1 protein. The horizontal line indicates the cutoff value for positivity (OD = 0.032: the average absorbance of the healthy individuals plus 2 SD). Positive sera were found in 13 of 24 (54.2%) patients with RCC but not in healthy donors. (C) Expression of PARG1 mRNA in normal kidney and RCC tissue in the same RCC patient sample was detected by qPCR analysis. GAPDH mRNA expression was used as an internal control. (D) Expression of PARG1 in human RCC cell lines was detected by qPCR analysis. GAPDH was used as an internal control. HEK293T was used as control sample for this assay.
