The heat shock response maintains cellular homeostasis following sublethal injury. Heat shock proteins (Hsps) are induced by thermal, oxyradical, and inflammatory stress, and they chaperone denatured… Expand
Dickkopf Homologs in Squamous Mucosa of Esophagitis Patients Are Overexpressed Compared with Barrett's Patients and Healthy Controls
OBJECTIVES:Esophageal mucosal response to acid exposure varies from minimal changes to erosions/ulcerations and Barrett's metaplasia. While differences in acid contact time have been suggested, the… Expand
Selective modulation of PKC isozymes by inflammation in canine colonic circular muscle cells.
BACKGROUND & AIMS Protein kinase C (PKC) is a key signaling molecule in excitation-contraction coupling in several types of smooth muscle cells. We investigated whether the attenuated contraction in… Expand
Hypoxia Preconditioning Increases Survival and Decreases Expression of Toll-Like Receptor 4 in Pulmonary Artery Endothelial Cells Exposed to Lipopolysaccharide
Pulmonary or systemic infections and hypoxemic respiratory failure are among the leading causes of admission to intensive care units, and these conditions frequently exist in sequence or in tandem.… Expand
Tissue protection and endothelial cell signaling by 20-HETE analogs in intact ex vivo lung slices.

The Cinchona bark contains alkaloids like quinine, quinidine, cinchonine and cinchonidine. These agents are effective antimalarial drugs and have been used clinically in malaria caused by Plasmodium… Expand
Protection by 20-5,14-HEDGE against surgically induced ischemia reperfusion lung injury in rats.
BACKGROUND We previously reported that the cytochrome P450 product 20-hydroxyeicosatetraenoic acid has prosurvival effects in pulmonary artery endothelial cells and ex vivo pulmonary arteries. We… Expand

Goals To determine expression and localization of Wnt signaling molecules across the esophageal mucosal thickness. Background The molecular mechanisms governing the biology and pathobiology of… Expand
Resveratrol enhances mitomycin C-mediated suppression of human colorectal cancer cell proliferation by up-regulation of p21WAF1/CIP1.
BACKGROUND/AIM Studies have shown that natural products could potentially be employed in combination therapies to decrease toxicity to healthy tissues by chemotherapy drugs. No studies however, have… Expand
