Expression of cyclooxygenase‐2 in prostate carcinoma

Abstract

Nonsteroidal antiinflammatory drugs inhibiting cyclooxygenase (COX) enzyme activity in both its constitutive (COX-1) and inducible (COX-2) isoforms were shown also to inhibit the development of colon carcinoma in animal models. COX-2 is an inducer of angiogenesis of new blood vessels. The expression of COX-1 and COX-2 in prostate tissues from patients with prostate carcinoma was investigated using reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry.
