Figure 5From: Hsp90β inhibition modulates nitric oxide production and nitric oxide-induced apoptosis in human chondrocytes Hsp90β silencing diminishes the cellular death of chondrocytes induced by nitric oxide. Determination of apoptosis levels by flow cytometry (A) or ELISA (B) in chondrocytes exposed to 1 mM SNP. In the flow cytometry assays, data are represented as percentage of apoptotic (hypodiploid) nuclei, whereas the ELISA experiments show absorbance units relative to basal conditions (*, p < 0.05; **, p < 0.01 vs basal or SNP-treated, as indicated). Data represent the mean (±SE) of three independent experiments performed in duplicate.Back to article page
