From: Effects of nicotine on microRNA-124 expression in bile duct ligation-induced liver fibrosis in rats
Immunohistofluorescent study using an anti-STAT-3 antibody (green) in a representative rat liver obtained from normal saline or nicotine-treated sham or bile duct ligated rats. Nuclei were stained with DAPI (×400 magnification). Bile duct ligation-induced liver fibrosis leads to increased protein expression of STAT-3 in the liver. The liver of fibrotic rats exposed to nicotine demonstrated an increased expression of STAT-3.
