Nonsteroidal anti-inflammatory drugs upregulate function of wild-type and mutant CFTR.

Aspirin and some other nonsteroidal anti-inflammatory drugs inhibit cystic fibrosis transmembrane conductance regulator protein gene expression in T-84 cells.

Cystic fibrosis (CF) is caused by mutations in the CF gene, which encodes CF transmembrane conductance regulator protein (CFTR), a transmembrane protein that acts as a cAMP-regulated chloride channel The disease is characterized by inflammation but the relationship between inflammation, abnormal transepithelial ion transport, and the clinical manifestations of CF are uncertain. The present stud...

O-28: New Insights into the Mechanisms UnderlyingChlamydia Trachomatis Infection InducedFemale Infertility

Background: Chlamydia (C.) trachomatis is an obligate intracellular gram-negative pathogen affecting over 600 million people worldwide with 92 million new cases occurring globally each year. Genital C. trachomatis infection has been recognized as the most common cause of pelvic inflammatory disease leading to severe tubal damage, ectopic pregnancy, hydrosalpinx and infertility. However, the mec...

QSARS OF ANTI-FUNGAL ACTIVITY OF FURAN CARBOXANILIDE DERIVATIVES AGAINST WILD AND MUTANT STRAINS OF USTILAGO MAYDIS

The structural requirements for the inhibitor activity of various furan carboxanilide derivatives against succinate dehydrogenase complex (SDC) activity in mitochondria of either wild or mutant strains of Ustilago maydis were investigated with the aid of Hansch QSAR analysis. It has been found that the inhibitor activity against both types of enzymes is best related to the ??? or ??M of th...

A Rare Complication with the Concomitant use of Warfarin and Nonsteroidal Anti-Inflammatory Drugs: Hemoperitoneum and Intramural Small Bowel Hematoma

Prostaglandin synthase 1 gene disruption in mice reduces arachidonic acid-induced inflammation and indomethacin-induced gastric ulceration

Cyclooxygenases 1 and 2 (COX-1 and COX-2) are key enzymes in prostaglandin biosynthesis and the target enzymes for the widely used nonsteroidal anti-inflammatory drugs. To study the physiological roles of the individual isoforms, we have disrupted the mouse Ptgs1 gene encoding COX-1. Homozygous Ptgs1 mutant mice survive well, have no gastric pathology, and show less indomethacin-induced gastric...
