Abstract:

Glucocorticoids (GCs) are endogenous steroid hormones that regulate a number of critical physiological processes. Psychological stress increases the level of GCs in the circulating system. The biological effect of elevated GCs on the heart is not well understood. We found that GCs induced Cyclooxygenase-1 (COX-1) and COX-2 gene expression in cardiomyocytes. COX-1 or COX-2 encodes the rate-limiting enzyme in the biosynthesis of prostanoids, which modulate crucial physiological and pathophysiological responses. The present studies aim to elucidate the signaling transduction pathway and the

Abstract:

The purpose of this study was to assess the prognostic significance and clinical correlations of cyclooxgenase-2 expression (COX) in a cohort of patients treated with radiation (RT) for post-mastectomy chest wall relapse (PMCWR). Between 1975 and 1999, 113 patients were treated for isolated PMCWR. All patients were treated with biopsy and/or excision of the CWR followed by RT. Median follow-up was 10 years. All clinical data including demographics, pathology, staging, receptor status, HER-2/neu status, and adjuvant therapy were entered into a computerized database. Paraffin-embedded CWR specim

Abstract:

Chronic obstructive pulmonary disease (COPD) is an inflammatory disease of the lungs caused by cigarette smoke exposure; COPD is also now the third leading cause of death worldwide. Controlling lung inflammation is a priority in COPD patients, but currently-available medications offer little relief. Thus, new therapeutic targets represent a major unmet need. Previously, the aryl hydrocarbon receptor (AHR) has been shown to suppress cigarette smoke-induced inflammation. The AHR is a ligand-activated transcription factor, and well-established for its response to xenobiotic ligands. AHR-mediated

Abstract:

The COX-2 isozyme is overexpressed in several kinds of cancer, including colorectal, lung, breast, and oesophageal cancer. High levels of COX-2 are usually associated with poor prognosis and advanced disease. Furthermore, studies have suggested that co-administering COX-2 inhibitors along with classic chemotherapy can improve disease outcome. Therefore, COX-2 is an attractive PET imaging biomarker for patient stratification. A first library of potential COX-2 inhibitors with a 5,5-diphenyl hydantoin core was synthesised and screened for its affinity for COX isozymes. This structure was chosen

Abstract:

Wernicke's encephalopathy is a neuropsychiatric disorder resulting from thiamine deficiency (TD) and is characterized by neuronal loss, astrocytic proliferation and microglial activation. Cyclooxygenases (COX) are enzymes which catalyze the first step in the synthesis of prostanoids. COX-1 is expressed constitutively and COX-2 is the inducible isoform. Groups of TD rats and pair-fed controls were killed at presymptomatic and symptomatic stages of encephalopathy.

Abstract:

Cyclooxygenase-2 (COX-2) is an enzyme that plays a key role in the synthesis of prostaglandin (PGE2). COX-2 has been widely investigated in cancer progression studies generally and in colorectal cancer (CRC) specifically, not only because it is regulated by various signalling pathways, but also because it is one of the main players in the inflammation/cancer link. The nuclear factor kappa-light-chain-enhancer of activated B cells (NF-KB) is among the transcription factors that have been repOlied to regulate the transcriptional activity of the COX-2 gene. Constitutive activity of NF-KB clearly

The purpose of this investigation was to determine the expression of the COX-1 (COX-1 variants: COX-1 v1, -1v2, -1 b,, -1 b2, and -1b3) and COX-2 isoforms following resistance exercise to help elucidate the isoform or variant through which PGF2a, ibuprofen, and ace

Therefore, the aim of this thesis was to characterize NSCLC in order to find new treatment targets and to evaluate biomarkers that further optimize therapy selection. In Paper I, the ex

By, immunohistochemistry, both COX-1 and COX-2 were localized to the intercalated cells of the collecting duct on paraffin embedded mouse kidney sections. When COX enzyme activity was measured in the M-1 cells, both indomethacin (COX-1 and -2 inhibitor) and the specific COX-2 inhibitor NS-398 effectively blocked PGE2 synthesis. These

In contrast, we and others have found that COX-1, not COX-2, is responsible for vascular prostacyclin production. Our experiments have relied on immunoassays to detect the prostacyclin breakdown product, 6-keto-PGF1α and antibodies to detect COX-2 protein. Whilst these are standard approaches, used by many laboratories, antibody-based techniques are inherently indirect and have

The effect of homocysteine on T lymphocyte cell line (Jurkat cell) COX-2 expression was examined in vitro. The result from this study may provide insight into the mechanisms contributing to inflammatory response in patients with hyperhomocysteinemia. Experimental results showed that homocysteine can induce T lymphocytes resulting from inflammation, but one of the major regulatory mechanisms is not clear . This study found that the T

This study was to know the COX-2 expression in precancerous lesions tissue and to evaluated the inhibition of propolis on COX-2 expression. By Western blot assay, the COX-2 expression was great in the oral cancer tissue followed by leukoplakia and OSF. The levels of COX-2 expression also showed positive correlation with the severity of each lesions. Immunohistochemistry analysis showed that COX-2 expression in oral cancer tissue was very strong and much higher than in leukoplakia and OSF tissue. Furth

碩士<br>國立成功大學<br>藥理學研究所<br>103<br>Overexpression of EGFR is a common phenomenon in head and neck cancer squamous cancer cell (HNSCC). Activation of EGFR signaling pathway contributes to HNSCC metastasis and reduces patients’ survival. In our previous studies we found that EGF-induced angiopoietin-like 4 (ANGPTL4) was involved in tumor metastasis. However, the mechanisms of EGF-induced ANGPTL4 and the functional roles of ANGPTL4 in HNSCC metastasis remain unclear. In this study, we found that EGF activated ERK, but not NF-κB signaling pathway was involved in the regulation of ANGPTL4 expression.

In recent researches, adlay was also found that it has anti-tumor property in animal model. Chronic inflammation with a variety of epithelial malignancies has been recognized for centuries and it is thought that the key enzymes, COX-2 and iNOS, which are over- expressed during inflammation may be a general link between inflammation and cancer. In the present study, the effect of adlay extracts on COX-2 or iNOS expression was investigated in RAW264.7 cell and HT-29 cell. In

Because cyclooxygenase-2 (COX-2) plays a key role in prostaglandins (PGs) synthesis which is elevated in inflammation, this thesis examined whether the anti-inflammatory mechanism of berberine is mediated through COX-2 regulation. In oral cancer cell line OC2 and KB cells, a 12 hr berberine treatment (1, 10, and 100 μM) reduced prostaglandin E2 (PGE2) production dose-dependently with or without 12-O-tetradecanoylpho

Cyclooxygenase (COX)-2, the inducible isoform of prostaglandin synthase, has been implicated in tumor metastasis. Connective tissue growth factor (CTGF), a secreted protein that binds to integrins, modulates the invasive behavior of certain human cancer cells. However, the effect of CTGF on migration activity and COX-2 expression in human oral cells is mostly unknown. Here we found that CTGF reduced the migration and expression of COX-2 in human oral cancer cells.?n ?庮?

Endothelin-1(ET-1), a potent vasoconstrictor, has been shown to be a pro-inflammatory cytokine like TNF- and IL-1β. ET-1 may cause a variety of inflammatory diseases, including airway inflammation, cutaneous inflammation, Crohn’s disease, ulcerative colitis, and liver cirrhosis. Under

Recent studies indicated that cyclooxygenase-2 (COX-2) expression is frequently associated with lymph node metastasis and over-expression of COX-2 can enhance lymphatic invasion of cancer cells. The interaction of chemokines and their cognate receptors also plays a critical role in cancer metastasis. Previous results of our laboratory demonstrated that CCR7 is a downstream target for COX-2 and COX-2 up-regulated CCR7 expressio

Therefore, we used rat brain astrocyte cells (RBA cells) as a model to investigate p42/p44 MAPK, PDGFR, PI3K/Akt, PKC, NF-κB and AP-1 involved in EV71-induced iNOS and COX-2 expression using Western blotting, Reverse transcriptase-polymerase chain reaction (RT-PCR), and im
