Abstract:
In this study, we use primary embryonic fibroblasts derived from cyclooxygenase-deficient transgenic embryos to further investigate the role of the two cyclooxygenases, cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2), in the process of neoplastic transformation. Cells with either, neither, or both of the cyclooxygenases were transformed by Ha-ras and/or SV40. Our results show that when a cyclooxygenase enzyme is present, the transformed cells have marked increases in COX-2 and/or COX-1 expression. Nevertheless, each type of cell, deficient in either or both cyclooxygenases, can be readil

Abstract:
Cyclooxygenase is known to be the ratelimiting enzyme in the production of prostaglandins. So far, in different bird species there have been found two isoforms of cyclooxygenases (COX), cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2). These isoforms along with prostaglandins are regarded to possess a determining influence on the success in female reproduction. Only in a few bird species the expression sites of cyclooxygenases have been investigated. In this study we report on the expression of COX-1 and COX-2 in the ovary of the quail (Coturnix japonica) using PCR, immunohistochemistry a

Cyclooxygenases and lipoxygenases are proinflammatory enzymes; the former affects platelet aggregation, vasoconstriction, vasodilatation and later the development of atherosclerosis. Red wines from Georgia and central and western Europe inhibited cyclooxygenase-1 (COX-1) activity in the range of 63–94%, cyclooxygenase-2 (COX-2) activity in the range of 20–44% (tested at a concentration of 5 mL/L), and 5-lipoxygenase (5-LOX) activity in the range of 72–84% (at a concentration of 18.87 mL/L). White wines inhibited 5-LOX in the range of 41–68% at a concentration of 18.87 mL/L and did not inhibit

Abstract:
Prostaglandins are synthesized by the enzyme cyclooxygenase (COX), which is the target for nonsteroidal anti-inflammatory drugs (NSAIDs). Recently a second form of COX was discovered (COX-2) that is induced by inflammatory stimuli. The identification of an inducible form of COX led to the hypothesis that COX-2 is responsible for inflammatory prostaglandins, whereas the constitutive COX-I produces physiologically important prostaglandins, e.g., in stomach and kidney. Selective COX- 2 inhibitors have been shown to be anti-inflammatory but do not cause ulcers in the stomach or intestines. It is a

Abstract:
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used in the treatment of arthritis and pain. However, their long-term use is limited by gastrointestinal (GI) side effects such as gastric ulcers. NSAIDs act by inhibiting an enzyme called cyclooxygenase. Cyclooxygenase (COX) catalyses the generation of prostaglandins from arachidonic acid. Two isoforms of the enzyme exist – COX-1 and COX-2 – both of which are targets for NSAIDs. Although they are associated with GI toxicity, NSAIDs have important antithrombotic and anti-inflammatory effects. The GI injury has been attributed to COX-1 in

Cyclooxygenase (COX) is the rate limiting enzyme that catalyses the production of prostanoids, which are crucial to vascular homeostasis.

Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease with no available pharmacological treatment.

Similarly, in a mouse model of the disease induced by chronic Angiotensin II (AngII) infusion, we have shown that COX-2 expression in the abdominal aortic smooth muscle layer increases early in the development of the disease.

Abstract:
The goal of this proposal was to identify proteins of BLV recognized by lymphocyte subpopulations and determine the contribution of these proteins to viral pathogenesis. Our hypothesis was that BLV pathogenesis is governed by the T-cell response and that the immune system likely plays an important role in controlling the utcome of infection. Our studies presented in ths final report demonstrate that T cell competency declines with advancing stages of infection. Dramatic differences were observed in lymphocyte proliferation to recombinant proteins encoded by BLV gag (p12, p15, and p24) and env

Abstract:
Background: Mechanical stress such as orthodontic forces can produce mechanical damage and inflammatory reaction in periodontium. Osteopontin (OPN) is a multifunctional cytokine that found to be correlated with periodontal disease progression. As periodontal ligaments (PDL) can be affected by stress and PDL cells are involved in periodontal destruction and remodeling, we aimed to investigate the influence of mechanical stress on the expression and regulation of OPN in human PDL (HPDL) cells. Methods: The mechanical stress was generated by continuous compressive force and the expression of OPN

Abstract:
The vital role of the prostanoid pathway in inflammation, pain, cancer, Alzheimer’s and many other diseases has attracted the drug discovery community to discover targets for therapeutic development. Although existing non-steroidal anti-inflammatory drugs (NSAIDs) inhibiting cyclooxygenases (COX) are widely used, the side effects of these NSAIDs limit the ling time medication. Microsomal prostaglandin E synthase-1 (mPGES-1) is an attractive target that is overexpressed during inflammations, and it could be a safe alternative to NSAIDs for treating inflammatory diseases.Since the discovery of m

Abstract:
Oxytocin has multiple actions in bovine reproductive tract and it was our purpose to determine the nature of these actions and their significance for the physiology of bovine reproduction. The bovine oxytocin receptors (OTR) gene was cloned and its expression studied during the cycle and pregnancy. OTR mRNA changed in parallel with OTR with control occurring mainly at the transcriptional level. However, the endocrine regulation of OTR were found in endometrium and cervical mucosa at estrus and at parturition. In both tissues OTR were suppressed in the luteal phase and early pregnancy.
