abstract：:Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the incidence of colorectal cancer. However, evidence is accumulating that NSAIDs have anti-cancer effects in addition to inhibiting cyclooxygenase (COX)-mediated prostanoid biosynthesis. We now show that indomethacin, a popular NSAID, significantly reduced the [3H]...
