Increased sirtuin expression in patient with lung squamous cell carcinoma co-morbid with COPD

2015

Background: COPD is frequently associated with comorbidities, the most serious and prevalent include lung cancer. Sirtuin 1 (SIRT1) is known to deacetylate histones and non-histone proteins including transcription factors thereby regulating metabolism, stress resistance, cellular survival, cellular senescence/aging. The aim of our study was to evaluate SIRT-1 expression in patients with lung squamous cell carcinoma and adenocarcinoma and these co-morbid with COPD. Methods: 93 patients with lung nonsmall cell lung carcinoma co-morbid with moderate severity COPD (n=29) or without COPD were enrolled in the study. Lung function testing was performed within one week before lung surgery. SIRT-1 e…
