Expression Of Cycloxygenase-2 In Human Bladder And Renal Cell Carcinoma
Cyclooxygenase (COX) catalyses the synthesis of prostaglandins from arachidonic acid. There are two isoforms of COX (DuBois et al., 1998; vane et al., 1998). One is constitutively expressed (COX-1) and the other is inducible (COX-2). The COX-2 gene is an immediate, early-response gene that is induced by growth factors, oncogenes, carcinogens, and tumor-promoting phorbol esters (Inoue et al., 1995; Nanayama et al., 1995; Herschman, 1996). The constitutive isoform, COX-1, is essentially unaffected by these factors.
