Western blotting of C1β3GalT-1 (a) and RT-PCR analysis of the expression of sulfotransfease and other glycosyltransferase genes involved in the biosynthesis of mucin-type L-selectin ligand (b). β3GnT-3, GlcNAc6ST-1, FUT7, ST3Gal-III and -IV genes were expressed higher in C-81 than C-33 LNCaP cells. There was no difference in the expression of C2GnT-1, β4galT-1, β4galT-4 and iGnT genes between these two LNCaP cells
