MetabolomicsDefective mitochondrial COX1 translation due to loss of COX14 function triggers ROS-induced inflammation in liver
Mitochondrial oxidative phosphorylation (OXPHOS) fuels cellular ATP demands. OXPHOS defects lead to severe human disorders with unexplained tissue specific pathologies. Mitochondrial gene expression is essential for OXPHOS biogenesis since core subunits of the complexes are mitochondrial-encoded. CO...

TranscriptomicsGenetic disruption of COX-1 inhibits multiple oncogenic pathways
We performed RNA sequencing in isogenic models of COX-1 proficient (OV3/SCR) and COX-1 deficient (OV3/COX1KD) OVCAR-3 ovarian cancer cells. COX-1 knockdown was associated with a coordinated anti-oncogenic phenotype, with growth, angiogenesis, migration/invasion, and epithelial-mesenchymal transition...

TranscriptomicsFeedback amplication of fibrosis through matrix stiffening and COX-2 suppression
We tested the hypothesis that increasing matrix stiffness on which normal human lung fibroblasts are grown promotes the expression of a fibrogenic cellular transcriptomic program. Keywords: Human lung fibroblast, matrix stiffness, PTGS2, COX-2, Prostaglandin E2 Total RNA extracted from normal human...

TranscriptomicsCOX-2 network as predictive molecular marker for clinical pregnancy in IVF
CONTEXT Nowadays, the molecular mechanisms involved in endometrial receptivity and implantation are still not clear. OBJECTIVE The gene expression of human endometrium of patients undergoing an IVF treatment with GnRH antagonists/rec-FSH was studied. CONCLUSIONS COX-2 has been extensively studied ...

MetabolomicsCyclooxygenase-2, Asymmetric Dimethylarginine, and the Cardiovascular Hazard From Nonsteroidal Anti-Inflammatory Drugs (Murine kidney and plasma UPLC-MS/MS assay)

BACKGROUND: Large-scale, placebo-controlled trials established that nonsteroidal anti-inflammatory drugs confer a cardiovascular hazard: this has been attributed to depression of cardioprotective products of cyclooxygenase (COX)-2, especially prostacyclin. An alternative mechanis...

ProteomicsActivity-dependent COX-2 proteolysis
Cyclooxygenase-2 (COX-2) catalyzes the oxidation of arachidonic acid (AA) into a single product that is the source of all prostaglandins (PGs), ligands of multiple pro-inflammatory pathways. AA catalysis results in suicide inactivation, rendering the enzyme catalytically inactive. We report that cat...

TranscriptomicsTranscription profiling of mouse uterus from _gravidl_d18 wild type vs. Cox-1 knockout animal
Background: Preterm birth is the leading cause of all infant mortality. In 2004, 12.5% of all births were preterm. In order to understand preterm labor, we must first understand normal labor. Since many of the myometrial changes that occur during pregnancy are similar in mice and humans and mous...

TranscriptomicsCOX-2 overexpression in a conditional KrasG12D mouse model
Pancreatic ductal cells and preneoplastic lesions derived from wild type, Keratin 5 COX-2, P48Cretg/wt K-RasG12D/wt and K5 COX-2 P48Cretg/wt K-RasG12D/wt mouse genotypes were laser capture microdissected. Total RNA was isolated and analysed with Illumuna Sentrix 8 chips.

TranscriptomicsCell Intrinsic role of Cox-2 in pancreatic cancer development
Cyclooxygenase-2 (COX-2) is upregulated in pancreatic ductal adenocarcinomas (PDAC). However, how COX-2 promotes PDAC development is unclear. While previous studies have evaluated the efficacy of COX-2 inhibition via the use of non steroidal anti-inflammatory drugs (NSAIDs) or the COX-2 inhibitor ce...

MetabolomicsCyclooxygenase-2, Asymmetric Dimethylarginine, and the Cardiovascular Hazard From Nonsteroidal Anti-Inflammatory Drugs (Murine and human plasma quantitative L-arginine and methylarginines UPLC-MS/MS assay)

BACKGROUND: Large-scale, placebo-controlled trials established that nonsteroidal anti-inflammatory drugs confer a cardiovascular hazard: this has been attributed to depression of cardioprotective products of cyclooxygenase (COX)-2, especially prostacyclin. An alternative mechanis...
