Stability of HS-metabolic system upon different external and internal stimuli. (A) Expressions of key HS metabolism-involved genes in LNCaP and PC3 prostate cancer cells before and after the treatments with 5-aza-deoxycytidine (+5-aza-dC), Trichostatin A (+TSA), ectopic over-expression of GLCE (+GLCE), co-culture with human fibroblasts (+fibroblasts). The genes expression levels normalized to that of GAPDH. The graphs show the mean expression levels from triplicate experiments (±s.d.) (OriginPro 8.1). Genes up-regulated or down-regulated >2-fold are shown. (B) Relative activity of HS-metabolic machinery before and after the treatments. Stacked column compares the contribution of each value to a total across categories.
