Changes in the levels of NWD1 expression, and its possible correlation with PCa progression, were further investigated by quantitative PCR analysis using a normalized cDNA panel derived from isolated prostate samples (n=48) at different tumor stages (TissueScan Prostate Cancer Tissue qPCR Panel I, Origene) (Fig. 3B). The gene discussed is NWD1; the disease is Familial prostate cancer.
