(A) Relative expression of eight selected miRNAs and ten (B) mRNAs by RT-qPCR in validation set of samples. RNU48 (miRNAs) and GUSB (mRNAs) were used as references for RT-qPCR analysis. Parametric t test was applied to compare tumors with non-neoplastic penile tissue. NPT: Non-neoplastic penile tissue; PeCa: Penile Carcinoma, NS: not significant; *P < 0.05; **P < 0.01; ***P < 0.001.
