Papandreou C, Bogenrieder T, Finstad C, Freeman R, Chao M, Albino A, et al.
Urol Oncol . 2011 Jan; 4(6):210-7. PMID: 21227260
Reduced expression of the low-affinity p75 neurotrophin receptor (p75(NTR)) occurs in prostate epithelial cells during malignant transformation. Recent studies indicating that the p75(NTR) can transduce signals that induce apoptosis suggest...
