Cox-2 is regulated by Toll-like receptor-4 (TLR4) signaling: Role in proliferation and apoptosis in the intestine.
BACKGROUND & AIMS We recently showed that mice deficient in Toll-like receptor 4 (TLR4) or its adapter molecule MyD88 have increased signs of colitis compared with wild-type (WT) mice after dextranExpand

Tumor-associated macrophage-induced invasion and angiogenesis of human basal cell carcinoma cells by cyclooxygenase-2 induction.
Tumor-associated macrophages (TAMs) and cyclooxygenase-2 (COX-2) are associated with invasion, angiogenesis, and poor prognosis in many human cancers. However, the role of TAMs in human basal cellExpand

Carvacrol, a component of thyme oil, activates PPARα and γ and suppresses COX-2 expression[S]
Cyclooxygenase-2 (COX-2), the rate-limiting enzyme in prostaglandin biosynthesis, plays a key role in inflammation and circulatory homeostasis. Peroxisome proliferator-activated receptors (PPARs) areExpand

Regulation of Constitutive Cyclooxygenase-2 Expression in Colon Carcinoma Cells*
Cyclooxygenase-2 (COX-2) is not normally expressed in the human large intestine, but its levels are increased in the majority of human colorectal carcinomas. Here we investigate the regulation ofExpand

Enhancement of Human Cord Blood CD34+ Cell-Derived NK Cell Cytotoxicity by Dendritic Cells1
NK cells and dendritic cells (DCs) are both important in the innate host defense. However, the role of DCs in NK cell-mediated cytotoxicity is unclear. In this study, we designed two culture systemsExpand

Feedback control of cyclooxygenase-2 expression through PPARgamma.
Cyclooxygenase-2 (COX-2), a rate-limiting enzyme for prostaglandins (PG), plays a key role in inflammation, tumorigenesis, development, and circulatory homeostasis. The PGD(2) metaboliteExpand

Chrysin suppresses lipopolysaccharide‐induced cyclooxygenase‐2 expression through the inhibition of nuclear factor for IL‐6 (NF‐IL6) DNA‐binding activity
Chrysin is a natural, biologically active compound extracted from many plants, honey and propolis. It possesses potent anti‐inflammation, anti‐cancer and anti‐oxidation properties. The mechanism byExpand

Localization of cyclooxygenase-2 and regulation of its mRNA expression in gastric ulcers in rats.
It has been reported that cyclooxygenase-2 (COX-2) may play a crucial role in gastric ulcer healing. We examined the localization of COX-2 and the regulation of COX-2 mRNA expression in acetic acidExpand

CX3C-Chemokine, Fractalkine-Enhanced Adhesion of THP-1 Cells to Endothelial Cells Through Integrin-Dependent and -Independent Mechanisms1
Leukocyte adhesion and trafficking at the endothelium requires both cellular adhesion molecules and chemotactic factors. A newly identified CX3C chemokine, fractalkine, expressed on activatedExpand

Tyrosine phosphorylation of I-kappa B kinase alpha/beta by protein kinase C-dependent c-Src activation is involved in TNF-alpha-induced cyclooxygenase-2 expression.
The signaling pathway involved in TNF-alpha-induced cyclooxygenase-2 (COX-2) expression was further studied in human NCI-H292 epithelial cells. A protein kinase C (PKC) inhibitor (staurosporine),Expand
