RELB and Familial prostate cancer: Although the RelB levels were similar in a hormone-sensitive prostate cancer cell line (LNCap) and castration-resistant prostate cancer cells, and although ST3Gal I was expressed in LNCap cells [20], the expression of ST3Gal II was silenced in LNCap cells, and GD1a was much less abundant in the LNCap cells [17], [20].
