Immunohistochemistry of CUL4A in small airway epithelium. Representative photographs of the immunoreactivity against CUL4A in human small airways are shown. a Immunohistochemical staining of CUL4A in small airway epithelium from control never smokers; b CUL4A expression in small airway epithelium in smokers without COPD; c CUL4A expression in small airway epithelium in patients with COPD. The upper panels show low-magnification images, and the lower panels show magnified images; d Quantitative analysis of CUL4A positive cells in small airway epithelium. CNS, control never-smoker; CES, control ex-smoker; COPD, ex-smoker with COPD
