Nonsteroidal anti-inflammatory drugs (NSAIDs) are well known for treating inflammatory disease and have been reported to have anti-tumorigenic effects. Their mechanisms are not fully understood, but both cyclooxygenase (COX) dependent and independent pathways are involved. Our goal was to shed

Non-steroidal anti-inflammatory drugs prevent colorectal cancer by inhibiting cyclooxygenase (COX) enzymes that synthesize tumor-promoting prostaglandins. 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is a tumor suppressor that degrades tumor-promoting prostaglandins. Murine knockout of 15-PGDH increases susceptibility to azoxymethane-induced colon tumors. It also renders these

Sulindac is useful in regression of adenomatous polyps. In addition to orally administered sulindac, rectal preparations also appear to be efficacious [32]. However, further studies are necessary to determine whether regression of adenomas, the precursor of colorectal cancer, will cause
Paul J Limburg et al.
Lung cancer (Amsterdam, Netherlands), 79(3), 254-261 (2012-12-25)
Sulindac represents a promising candidate agent for lung cancer chemoprevention, but clinical trial data have not been previously reported. We conducted a randomized, phase II chemoprevention trial involving current or former cigarette smokers (≥30 pack-years) utilizing the multi-center, inter-disciplinary infrastructure

Sulindac has been identified as a competitive inhibitor of aldo-keto reductase 1B10 (AKR1B10), an enzyme that plays a key role in carcinogenesis. AKR1B10 is overexpressed in pancreatic ductal adenocarcinoma (PDAC) and exhibits lipid substrate specificity, especially for farnesyl and geranylgeranyl.
W R Waddell et al.
Journal of surgical oncology, 58(4), 252-256 (1995-04-01)
A putative explanation of the effect of sulindac on adenomatous colon and duodenal polyps from clinical observations and related in vitro experiments is presented. In cells with mutant APC genes, persistent high prostaglandin content of polyps leads to desensitization, downregulation
Nathaniel S Rial et al.
Expert review of gastroenterology & hepatology, 6(4), 507-517 (2012-08-30)
To reduce the morbidity and mortality from colorectal cancer (CRC), current clinical practice focuses on screening for early detection and polypectomy as a form of secondary prevention, complemented with surgical interventions when appropriate. No pharmaceutical agent is currently approved for

1.Sulindac, cis-5-fluoro-2-methyl-1-(p-methylsulphinylbenzylidene)indene-3-ace tic acid, inhibits growth of colon polyps and cancers. This effect has been attributed to inhibition of prostaglandin synthesis but more recent observations indicate that, in vitro, cells that do not have cyclo-oxygenase nor RNA for synthesis of
