(Submitter supplied) We report the impact of side-stream cigarette smoking on baseline tracriptional status of enriched epithelium from the distal lung of both male and female control mice or mice harboring a mutation in the nicotinc alpha7 recptor that selectivley diminshes the calcium current (E260A).

(Submitter supplied) Purpose: The goal of this study is to compare the effects of inhaled nicotine on aortic gene expression and the role of the alpha7 nicotinic acetylcholine receptor (alpha7-nAChR) in mediating the nicotine effects. Methods: WT and alpha7-nAChR knockout (KO) mice at 5-month of age were exposed to nicotine vapor or room air for a total of 12 weeks. Total RNA was extracted from thoracic aortas using RNeasy Plus mini kit followed by library preparation using SMART-Seq v4 Ultra Low Input RNA Kit. more...

(Submitter supplied) Background: When exposed to specific stimuli, macrophages exhibit distinct activation programs, M1 and M2 polarization, that define macrophage function as inflammatory/immune effectors or anti-inflammatory/tissue remodeling cells, respectively. Due to their position on the lung epithelial surface, alveolar macrophages (AM) directly interact with environmental stimuli such as cigarette smoke, the major risk factor for the development of chronic obstructive pulmonary disease (COPD). more...

(Submitter supplied) These studies tested the hypotheses that smoke induces changes in mRNA profiles that are dependent on sex and the health status of the lung, and that the effects of smoke are different after 1 day compared to 5 days of smoke exposure. The ways in which the lungs modulate their response to cigarette smoke after repeated exposures are important for understanding the toxicology of smoke, for developing biomarkers of chronic smoke exposure, and for understanding the therapeutic potential in regulatory signaling pathways that are beneficial or detrimental to lung health. more...

(Submitter supplied) Our previous study showed that AKR and C57BL/6 mice to cigarette smoke increased lipopolysaccharide (LPS)- induced increased lung vascular permeability. Viremic AKR mice were more susceptible to LPS-induced ALI than C57 on prolonged exposure. In this study we compared the global gene expression patterns to determine the genetic basis for the strain dependent responses to cigarette smoke and LPS-induced ALI. more...
