Figure 3From: Hsp90β inhibition modulates nitric oxide production and nitric oxide-induced apoptosis in human chondrocytes Hsp90β inhibitors prevent chondrocyte apoptosis induced by nitric oxide donors. Flow cytometry analysis of chondrocytes treated with NOC-12 (A), SNP (B) and the Hsp90β inhibitors GA and NB. Apoptosis is expressed as percentage of hypodiploid nuclei present in the population, and represent the mean (±SE) of four independent experiments by triplicate. Error bars indicate standard deviation of the mean (*, p < 0.05 vs basal).Back to article page
