Transgenic cyclooxygenase-2 overexpression sensitizes mouse skin for carcinogenesis.
Genetic and pharmacological evidence suggests that overexpression of cyclooxygenase-2 (COX-2) is critical for epithelial carcinogenesis and provides a major target for cancer chemoprevention by nonsteroidal antiinflammatory drugs. Transgenic mouse lines with keratin 5 promoter-driven COX-2 overexpression in basal epidermal cells exhibit a preneoplastic skin phenotype. As shown here, this phenot...
متن کاملCyclooxygenase-2 overexpression in the skin of transgenic mice results in suppression of tumor development.
Significant evidence has accumulated suggesting that the inducible form of cyclooxygenase (COX-2), a central enzyme in the prostaglandin biosynthetic pathway, plays an important role in tumor development. To better understand the role of COX-2 in tumorigenesis, we generated transgenic mice that overexpress COX-2 under control of the human keratin 14 promoter, which allows for expression in the ...

متن کاملProstaglandin receptor EP2 is responsible for cyclooxygenase-2 induction by prostaglandin E2 in mouse skin.
The EP2 prostanoid receptor is one of the four subtypes of receptors for prostaglandin E2 (PGE2). We previously reported that deletion of EP2 led to resistance to chemically induced mouse skin carcinogenesis, whereas overexpression of EP2 resulted in enhanced tumor development. The purpose of this study was to investigate the underlying molecular mechanisms. We found that EP2 knockout mice had ...
متن کاملOverexpression of cyclooxygenase-2 (COX-2) in the mouse urinary bladder induces the expression of immune- and cell proliferation-related genes.
The mechanisms whereby cyclooxygenase-2 (COX-2) overexpression may contribute to bladder carcinogenesis remain unknown. We recently developed a transgenic mouse model overexpressing COX-2 under the control of a bovine keratin 5 (BK5) promoter causing a high incidence of transitional cell hyperplasia (TCH) in the bladder with a proportion of lesions progressing to invasive carcinoma. Microarray ...
