Figure 1: Proteoglycans expression in normal human prostate tissue (a) and benign prostate hyperplasia (b). Intensity of the amplified DNA fragments normalised to that of GAPDH. Representative gels are shown (upper part). The graphs correspond to the lanes order and show the mean expression levels from triplicate experiments (±SD), (OriginPro 8.1). (c) Positive controls of undetected proteoglycans. M: 1 Kb-Plus DNA marker (Medigen), Gly: glypican-1, Perl: perlecan, Syn: syndecan-1, Agg: aggrecan, Vers: versican, NG2: neuron-glia 2; Brev: brevican, Dec: decorin, and Lum: lumican.
