(Submitter supplied) Oxidative stress as a result of cigarette smoking is an important etiological factor in the pathogenesis of chronic obstructive pulmonary disease (COPD), a chronic steroid-insensitive inflammatory disease of the airways. The activity of the transcriptional co-repressor Histone deacetylase-2 (HDAC2) is dramatically reduced in COPD and cells exposed to oxidative stress or cigarette smoke. Moreover, curcumin (diferuloylmethane), a dietary polyphenol, at concentrations upto 1uM specifically restores cigarette smoke extract (CSE)- or oxidative stress- impaired HDAC2 activity. more...

Analysis of U937 monoctyes exposed to oxidative stress then treated for 4 or 18 hrs with curcumin, a dietary polyphenol. Curcumin restores oxidative stress impaired histone deacetylase-2 activity and corticosteroid efficacy in vitro. Results provide insight into the molecular basis of these effects.
