The selective COX-2 inhibitor celecoxib modulates sphingolipid synthesis.
Sphingolipids such as ceramides (Cers) play important roles in cell proliferation, apoptosis, and cell cycle regulation. An increased Cer level is linked to the cytotoxic effects of several chemotherapeutics. Various selective cyclooxygenase-2 (COX-2) inhibitors induce anti-proliferative effects in tumor cells. We addressed the possible interaction of the selective COX-2 inhibitors, coxibs, wit...
متن کاملSelective COX-2 inhibitor celecoxib prevents experimental autoimmune encephalomyelitis through COX-2-independent pathway.
Cyclooxygenase (COX) is a key enzyme of arachidonic acid metabolism and exists as two distinct isoforms. COX-1 is constitutively expressed in most tissues, whereas COX-2 is inducibly expressed at the site of inflammation. Selective inhibitors of COX-2 have been developed and have been used as anti-inflammatory agents. Here, we show that a new-generation COX-2 inhibitor, celecoxib, inhibited exp...
متن کاملCelecoxib: a specific COX-2 inhibitor with anticancer properties.
In addition to the well-established pathophysiological role that COX-2 plays in inflammation, recent evidence implies that this isoform may also be involved in multiple biologic events throughout the tumorigenic process. Many epidemiological studies demonstrate that nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the risk of a wide range of tumors. Further, COX-2 is chronically overexpress...
متن کاملSelective COX-2 Inhibitor (Rofecoxib) Inhibits Vinorelbine Cytotoxicity in C6 Glioma Cells In Vitro
We examined the effects of gemcitabine, a novel nucleotide analogue, and vinorelbine, a semi-synthetic vinca alcaloid, in C6 glioma cell culture. We simultaneously monitored the modulation of its activity in combination with the telomerase inhibitory agent dimetilsülfoxid and with a specific cyclooxygenase-2 inhibitory agent Rofecoxib. The effects of the gemcitabine/ vinorelbine combination wer...
متن کاملThe effect of meloxicam, a selective COX-2 inhibitor, on the microvasculature of small metastatic liver tumors in rats.
BACKGROUND COX-2 is involved in tumor angiogenesis and modulation of the production of angiogenetic factors by colorectal carcinoma cells. It has been shown that COX-2 inhibitors have inhibitory activities against various types of tumor, including colorectal carcinoma. In this study, we investigated the tumor vessels of small metastatic liver tumors in rats and the effect of meloxicam, a select...
