Bu çalışmada adropin ve speksin peptitlerinin siklooksijenaz (COX) araşidonat lipooksijenaz (ALOX) gen ekspresyonları üzerindeki etkisinin kronik renal yetmezlik ekseninde gelişen kardiyak hasarda incelenmesi amaçlanmıştır.
 Sıçanlarda Kronik Renal Yetmezlik (KRY) modeli 10 gün boyunca adenin hemisülfat çözeltisinin gavaj yoluyla verilmesiyle oluşturulmuştur. Speksin tedavisi için 35 µg/kg...

Prostaglandin-endoperoxide synthase 2 (PTGS2), also known as cyclooxygenase 2 (COX-2), plays a critical role in many normal physiological functions and modulates a variety of pathological conditions. The ability to turn endogenous COX-2 on and off in a reversible fashion, at specific times and in specific cell types, would be a powerful tool in determining its role in many contexts. To achieve ...

OBJECTIVE Prostaglandin E2 (PGE2) synthesis is modulated by COX2. Changes in PGE2 could be used to quantify the COX2 inhibition after ibuprofen administration. This study investigated the pharmacokinetic and pharmacodynamic relationships for COX2 inhibition according to three formulations of ibuprofen in healthy male subjects. MATERIALS AND METHODS A randomized, open-label, single-dose, three...

Ligand activation of peroxisome proliferator–activated receptor-b/d (PPARb/d) and inhibition of cyclooxygenase-2 (COX2) activity by nonsteroidal anti-inflammatory drugs (NSAID) can both attenuate skin tumorigenesis. The present study examined the hypothesis that combining ligand activation of PPARb/d with inhibition of COX2 activity will increase the efficacy of chemoprevention of chemically in...

Depending on sequence, bacterial and synthetic DNAs can activate the host immune system and influence the host response to infection. The purpose of this study was to determine the abilities of various phosphorothioate oligonucleotides with cytosine-guanosine-containing motifs (CpG DNA) to activate macrophages to produce nitric oxide (NO) and prostaglandin E(2) (PGE(2)) and to induce expression...

This study aimed to investigate the real-time fluctuation of temperature-sensitive gene expression in a Pythium insidiosum growing at human body temperature (37 ºC) when it can cause life-threatening disease, whereas its natural habitat is agricultural water sources with lower temperature. Genes encoding cytochrome oxidase 2 (COX2), β-tubulin (TUB), and chitin synthase subunit (CHS2) were teste...

The COX2 rs5277 (306G>C) polymorphism has been associated with inflammation-associated cancers. In breast cancer, tumor COX-2 expression has been associated with increased estrogen levels in estrogen receptor (ER)-positive and activated Akt-pathway in ER-negative tumors. Our study investigated the impact of COX2 genotypes on early breast cancer events and treatment response in relation to tumor...
