Chronic obstructive pulmonary disease is marked by alveolar enlargement and excess production of airway mucus. Acrolein, a component of cigarette smoke, increases mucin 5AC (MUC5AC), a prevalent airway mucin in NCI-H292 cells by transcriptional activation, but the signal transduction pathways involved in acrolein-induced MUC5AC expression are unknown.(More)
RATIONALE Acute lung injury can occur from multiple causes, resulting in high mortality. The pathophysiology of nickel-induced acute lung injury in mice is remarkably complex, and the molecular mechanisms are uncertain. OBJECTIVES To integrate molecular pathways and investigate the role of transforming growth factor beta (TGF-beta) in acute lung injury in(More)
Often fatal, acute lung injury has a complicated etiology. Previous studies from our laboratory in mice have demonstrated that survival during acute lung injury is a complex trait governed by multiple loci. We also found that the increase in metallothionein (MT) is one of the greatest noted in transcriptome-wide analyses of gene expression. To assess the(More)
Chronic obstructive pulmonary disease (COPD), a global public health problem, is characterized by progressive difficulty in breathing, with increased mucin production, especially in the small airways. Acrolein, a constituent of cigarette smoke and an endogenous mediator of oxidative stress, increases airway mucin 5, subtypes A and C (MUC5AC) production;(More)
Rationale: Acute lung injury can occur from multiple causes, resulting in high mortality. The pathophysiology of nickel-induced acute lung injury in mice is remarkably complex, and the molecular mechanisms are uncertain.

The protective antigen protein, one of the three separate proteins constituting the exotoxin system of Bacillus anthracis, has been crystallized in a form suitable for structural studies. The crystal form which is most amenable to x-ray analysis is orthorhombic, space group P2(1)2(1)2(1), a = 101.1 A, b = 95.4 A, c = 87.3 A, with one protective antigen(More)
