Hydroxy fatty acids are critical lipid mediators involved in various pathophysiologic functions. We cloned and identified GPR31, a plasma membrane orphan G protein-coupled receptor that displays high affinity for the human 12-lipoxygenase-derived product 12-(S)-hydroxy-5,8,10,14-eicosatetraenoic acid (HETE). Thus, GPR31 is named 12-(S)-HETE receptor(More)
BACKGROUND Although laparoscopic surgery has been available for a long time and laparoscopic cholecystectomy has been performed universally, it is still not clear whether open appendectomy (OA) or laparoscopic appendectomy (LA) is the most appropriate surgical approach to acute appendicitis. The purpose of this work is to compare the therapeutic effects and(More)
Trichophyton rubrum (T. rubrum) is a major pathogen responsible for dermatophytosis. Because of potential relapse of disease with current antifungal therapy protocols, there is a need for additional and/or alternative antifungal agents for the treatment of disease caused by T. rubrum. We synthesized a potent fungal fatty acid synthase inhibitor, PHS11A,(More)
Physiological roles of microsomal (iPLA(2)gamma) and cytosolic (iPLA(2)beta)Ca(2+)-independent phospholipase A(2) were determined in two different epithelial cell models. R- and S-enantiomers of the iPLA(2) inhibitor bromoenol lactone (BEL) were isolated and shown to selectively inhibit iPLA(2gamma) and iPLA(2beta), respectively. The effect of these(More)
Our laboratory demonstrated that endoplasmic reticulum iPLA2 (ER-iPLA2) activity protects renal cells from oxidant-induced cell death and lipid peroxidation. The goals of this study were to determine the PLA2 isoform(s) responsible for ER-iPLA2 activity in different species and tissues. ER-iPLA2 activity was observed in microsomes from rabbit and rat(More)
Trichophyton rubrum is the most common dermatophyte causing fungal skin infections in humans. Asexual sporulation is an important means of propagation for T. rubrum, and conidia produced by this way are thought to be the primary cause of human infections. Despite their importance in pathogenesis, the conidia of T. rubrum remain understudied. We intend to(More)
Sphingosine-1-phosphate (S1P) regulates a wide array of biological functions in endothelial cells. We previously showed that S1P receptor subtype 2 (S1P2) is significantly up-regulated in the atherosclerotic endothelium (J. Biol. Chem. 283:30363, 2008). In this study, we investigated the roles of S1P2-mediated signaling in the proinflammatory responses of(More)
Conidia are considered to be the primary cause of infections by Trichophyton rubrum. We have developed a cDNA microarray containing 10250 ESTs to monitor the transcriptional strategy of conidial germination. A total of 1561 genes that had their expression levels specially altered in the process were obtained and hierarchically clustered with respect to(More)
Dermatophytes are the primary causative agent of dermatophytoses, a disease that affects billions of individuals worldwide. Trichophyton rubrum is the most common of the superficial fungi. Although T. rubrum is a recognized pathogen for humans, little is known about how its transcriptional pattern is related to development of the fungus and establishment of(More)
Osteoarthritis (OA), which is also called degenerative arthritis, is the leading cause of disabilities in the old people. The Chinese traditional herb Epimedium grandiflorum had long been found to attenuate osteoarthritis process, but the detailed mechanism was not clear. To study the mechanisms of E. grandiflorum in the treatment of osteoarthritis, rabbit(More)
