Hematopoietic Prostaglandin D Synthase Suppresses Intestinal Adenomas in Apc Mice
Aspirin and other nonsteroidal anti-inflammatory drugs prevent some cases of colon cancer by inhibiting prostaglandin (PG) synthesis. PGE2 promotes colon neoplasia, as shown by knockout mouse studies on enzymes and receptors in the PG cascade. A few experiments 20 to 30 years ago suggested that PGD2 may suppress tumors, but a role for biosynthetic enzymes for PGD2 in tumor development has not b...
متن کاملChemopreventive efficacy of combined piroxicam and difluoromethylornithine treatment of Apc mutant Min mouse adenomas, and selective toxicity against Apc mutant embryos.
Genetic knockout or pharmacological inhibition of cyclooxygenase-2 decreases the number and size of adenomas in mouse models of familial adenomatous polyposis. Epidemiological and clinical studies in humans indicate that the entire class of nonsteroidal anti-inflammatory drugs (NSAIDs) that inhibit both COX-1 and COX-2 enzymes are promising colon cancer chemopreventive agents. We used the Apc m...
متن کاملRetinoids as chemopreventive agents.
Retinoids are promising agents for cancer chemoprevention. The myriad effects of retinoids on biological processes including development, differentiation, homeostasis, carcinogenesis and apoptosis are mediated through their molecular targets, the retinoid and rexinoid receptors. Tissue specific expression patterns, ligand specificities, receptor numbers, their distinct functions and functional ...
متن کاملCompound disruption of smad2 accelerates malignant progression of intestinal tumors in apc knockout mice.
Smad2 is a receptor-regulated Smad that is activated specifically by transforming growth factor beta and activin signaling. We disrupted the mouse Smad2 gene by gene targeting. Homozygous Smad2 mutant mice died around E8.5 with impaired visceral endoderm function and deficiency of mesoderm formation. Heterozygotes were fertile and had no apparent abnormality up to at least 1 1/2 year of age. To...
متن کاملCalorie restriction and diet composition modulate spontaneous intestinal tumorigenesis in Apc(Min) mice through different mechanisms.
We evaluated the effects of diet on intestinal tumorigenesis in male Apc(Min) mice by comparing AIN-76A diet fed ad libitum (CON); calorie intake restricted by 40% of the CON (CR); diet high in olive oil and supplemented with freeze-dried fruit and vegetable extracts (OFV); and diet high in total fat (HF). Compared with CON, the frequency of intestinal polyps was reduced by 57% by CR (P < 0.001...
