In this study the potential anticancer effect of 2 flavonoids, myiricetin (MYR) and naringenin (NAR) has been evaluated on an oral squamous cell carcinoma (OSCC) cell line, SCC-25, and HaCaT cells. Both the flavonoids inhibited SCC-25 cell growth, although NAR selectively affected cancer cells without impairing HaCaT cell growth. The cell proliferation inhibition by MYR and NAR was not related to apoptosis induction, but on cell cycle impairment, because a G0/G1 and a G2/M blockage was highlighted following 24 h of treatment in SCC-25 and HaCaT cells, respectively. Western blot analysis showed that MYR induced a decrease of Cyclin D1 in SCC-25 and of Cyclin B1b in HaCaT cells, while NAR negatively modulated Cyclin D1 expression in SCC-25 cells. Wound-healing and cell invasion assays demonstrated that both the flavonoids were able to reduce motility on both SCC-25 and HaCaT cells. In conclusion the results of the present study show the anticancer potential of NAR and MYR on OSCC because they exert cytostatic effect by the impairment of cell cycle progression. Moreover both the flavonoids inhibit cell migration, thus highlighting their potential effect as antimetastatic agents. Therefore, MYR and NAR appear as promising candidate as oral cancer chemopreventive agents.
