Analysis of asbestos-induced gene expression changes in bronchiolar epithelial cells using laser capture microdissection and quantitative reverse transcriptase-polymerase chain reaction
…Extraction of RNA from microdissected tissue followed by quantitative reverse transcriptase-polymerase chain (QRT-PCR) reaction permits the analysis of cell-type or microstructure-specific gene expression changes that occur in response to various stimuli in…

Malignant peritoneal mesothelioma and Crohn disease
Mesothelial reaction simulating peritoneal diffuse malignant mesothelioma (MM) has been reported in the setting of Crohn ileitis. To our knowledge, peritoneal MM arising in patients with inflammatory bowel disease (IBD) has not been reported. The purpose…

Asbestos-induced peribronchiolar cell proliferation and cytokine production are attenuated in lungs of protein kinase C-delta knockout mice
…decreased in PKCdelta-/- mice. At 9 days, microarray and quantitative reverse transcriptase-polymerase chain reaction analysis of lung tissues revealed increased mRNA levels of the profibrotic cytokine, IL-4, in asbestos-exposed wild-type mice but…

Modulation of mitochondrial gene expression in pulmonary epithelial cells exposed to oxidants
…RNA was extracted, reverse transcribed, and amplified by polymerase chain reaction with degenerate primers to visualize alterations in gene expression. The seven clones obtained were sequenced and encoded the mitochondrial genes, NADH dehydrogenase subunits ND5 and…

Prevention of asbestos-induced cell death in rat lung fibroblasts and alveolar macrophages by scavengers of active oxygen species
…active oxygen species. In this regard, the iron associated with the fiber and/or its interaction with cell membranes might be critical in driving a modified Haber-Weiss (Fenton-type) reaction resulting in production of OH(.).

Oxygen radicals and asbestos-mediated disease
Asbestos fibers are potent elaborators of active oxygen species whether by reactions involving iron on the surface of the fiber, or by attempted phagocytosis of fibers by cell types resident in the lung. The link between…

Cell signaling pathways elicited by asbestos
…integrins. Alternatively, signaling pathways may be stimulated by active oxygen species generated both during phagocytosis of minerals and by redox reactions on the mineral surface. At least two signaling cascades linked to activation of transcription factors…
