Differential expression of heat shock proteins and activation of mitogen‐activated protein kinases in A549 alveolar epithelial cells exposed to cigarette smoke extract

New Findings What is the central question of this study? What is the effect of cigarette smoke on cell death, oxidative damage, expression of heat shock proteins (HSPs) and activation of mitogen‐activated protein kinases (MAPKs) in A549 alveolar epithelial cells? What is the main finding and its importance? Cigarette smoke induces cytotoxicity and oxidative damage to A549 cells, increases expression of different HSPs and activates MAPK...
