Figure 3

mRNA levels of DPP IV (A) and NEP (B) measured in tumour and nontumour tissue (normal) for CCRCC (n = 16), ChRCC (n = 6) and RO (n = 4) patients. RT-PCR data for each analyzed sample are recorded as relative units. The mean ± SE, p values and "normal/tumour" ratio of expression levels are also represented. *Statistically significant. ns no significant.
