TL;DR: Targeting of inflammatory states with non-steroidal anti-inflammatory drugs (NSAID'S) is an attractive proposition for cancer prevention and the possibility of applying NSAIDs in conjunction with other chemopreventive agents and developing specific inhibitors of different stages in the pathways leading to prostaglandin production and functions hold hope for improved drugs/protocols with reduced detrimental side effects.

Abstract: Introduction: Targeting of inflammatory states with non-steroidal anti-inflammatory drugs (NSAID'S) is an attractive proposition for cancer prevention. There is abundant epidemiological and experimental evidence that NSAID'S can inhibit tumour development in a number of organs and such drugs have given positive results in human intervention studies. It is hoped that problems with side effects can be overcome by development of specific inhibitors of cancer- and inflammation-associated enzymes. NSAID Pharmacology: Starting with the production of aspirin, NSAIDs have received an enormous amount of clinical attention. Inhibitors of the two isoforms of cyclooxygenase (COX) or prostaglanding G/H synthase, they have found widespread application with increasing interest focused on their employment for cancer prevention. Particular attention is now being drawn to specific inhibitors of the inducible C0X-2 rather than the constitutive COX-1 isoform. Mechanisms of Action: NSAIDs appear to act via depression of prostaglandin synthesis through inhibiting COX-2, often overexpressed in cancers, and the resultant suppression of proliferation, possibly through enhancement of apoptosis. Future Prospectives: The possibility of applying NSAIDs in conjunction with other chemopreventive agents and developing specific inhibitors of different stages in the pathways leading to prostaglandin production and functions hold hope for improved drugs/protocols with reduced detrimental side effects for employment in both primary and secondary cancer prevention in the future.

TL;DR: Results suggest that 400 ppm nimesulide in diet, when given during the promotion phase, exerts chemopreventive ability against 4-NQO-induced tongue tumorigenesis through inhibition of cell proliferation activity in conjunction with modification of COX-2 and iNOS expression of the target lesions.

TL;DR: Preventative effects of bLF and its fragment peptide, lactoferricin (bLFcin), consisting of a 25 amino acid sequence without iron binding capacity, on chemically-induced colon carcinogenesis in the rat and transplanted carcinoma cell metastasis in the mouse show multi-functional potential to suppress carcinogenesis.

Inhibition of prostaglandin synthesis as a mechanism of action for aspirin-like drugs
TL;DR: Experiments with guinea-pig lung suggest that some of the therapeutic effects of sodium salicylate and aspirin-like drugs are due to inhibition of the synthesis of prostaglandins.

TL;DR: COX-2, but not COX-1, gene expression is markedly elevated in most human colorectal cancers compared with accompanying normal mucosa, and COx-2 expression seems to be increased in a subset of adenomas.

Francis M. Giardiello,Stanley R. Hamilton,Anne J. Krush,Steven Piantadosi,Linda M. Hylind,Paul Celano,Susan V. Booker,C. Rahj Robinson,G. Johan A. Offerhaus +8 more
TL;DR: Sulindac reduces the number and size of colorectal adenomas in patients with familial adenomatous polyposis, but its effect is incomplete, and it is unlikely to replace colectomy as primary therapy.
