Induction of DU145 cell death by glucosamine. A, DU145 cells were cultured in the absence or presence of 1, 2, 4 or 8 mM glucosamine for 2 days in 24-well plates. Percent of dead cells was examined by trypan blue staining. B, apoptosis in DU145 cells after treatment with 2 mM glucosamine for 24 h. The results of a representative experiment are presented as mean ± standard deviation of the three independent samples. All experiments were repeated at least three times.
