RT-qPCR analysis of TCTP in normal kidney and neoplastic specimens. Relative expression of TCTP mRNA was detected in normal kidney and in tumor samples. Values are expressed as the result of normalization using placenta samples. The graphs are representative of three different RT-qPCR experiments. Error bars represent standard deviation between duplicates. (a) TCTP mRNA was detected in normal kidney and, at higher level, in malignant tumor samples. (b) In normal kidney, a higher TCTP mRNA level was detected in the cortical region with respect to medullary region (CCRCC: clear cell renal cell carcinoma; PRCC: papillary renal cell carcinoma; ChRCC: chromophobe renal cell carcinoma; CDC: collecting duct carcinoma; WT: Wilm’s tumour).
