NDRG1 and prostate carcinoma: While the N-terminal NDRG1 antibody gave rise to the 46 kDa full-length NDRG1 protein in all cell lysates (Figure 5B), the C-terminal NDRG1 antibody detected the 46 kDa full-length NDRG1 protein and the 41 kDa cleaved NDRG1 protein in only the prostate cancer cell lines (Figure 5A).
