Effects of indomethacin, cisplatin and delta 12-prostaglandin J2 on growth of oral squamous carcinoma cells.

The effect of indomethacin, cisplatin and delta 12-prostaglandin J2 (PGJ2) on the inhibition of cell growth and DNA Synthesis (i.e. cell proliferation), was evaluated in vitro on human oral squamous carcinoma cells(SCC-25). The rank order of their inhibitory potency at 10(-5) M was delta 12-PGJ2 > cisplatin > indomethacin. However, delta 12-PGJ2 at 10(-7) and 10(-6) M induced a significant stimulatory effect on cell growth as well as DNA synthesis. The sefindings suggest that delta 12-PGJ2 is a promising novel chemotherapeutic agent for oral cancer and potential candidate for future clinical investigations.
