Figure 6From: Glucosamine suppresses proliferation of human prostate carcinoma DU145 cells through inhibition of STAT3 signalingInhibition of cancer cells growth by glucosamine is associated with the suppression of STAT3 (Y705) phosphorylation. A, DU145, PC-3, C4-2B and Hela cells grown in 6-well plates either left untreated or were treated with 2 mM glucosamine for 24 h, and whole-cell extracts were used for Western blot analysis. Representative blot from at least three independent experiments with similar results is shown. B, Viability of cells grown in 96-well plates without or with 2 mM glucosamine for 3 days. Viability was assessed by MTT assay. All experiments were repeated at least three times with similar results. The results of a representative experiment are presented as mean ± standard deviation of three independent samples.Back to article page
