Anticancer Effects

Abstract Kava is a beverage made from the ground roots of the plant Piper Methysticum. Active compounds of Kava have previously been demonstrated to exert an antiproliferative effect through cell cycle arrest and promotion of apoptosis. Our aim was to investigate the in vitro effects of the main constituents derived from Kava on oral squamous cell carcinoma (OSCC) activity. Gas chromatography mass spectrometry (GCMS) was used to characterise the main constituents of two Kava preparations. Cell proliferation was assessed in two human OSCC cell lines (H400 and BICR56) and in normal oral keratinocytes (OKF6) treated with the identified Kava constituents, namely Flavokawain A (FKA), Flavokawain B (FKB), yangonin, kavain and methysticin using an MTS in vitro assay. Cell migration at 16 h was assessed using a Transwell migration assay. Cell invasion was measured at 22 h using a Matrigel assay. Cell adhesion was assessed at 90 min with a Cytoselect Adhesion assay. The two Kava preparations contained substantially different concentrations of the main chemical constituents. Treatment of malignant and normal oral keratinocyte cell lines with three of the identified constituents, 10 μg/ml FKA, 2.5 μg/ml FKB and 10 μg/ml yangonin, showed a significant reduction in cell proliferation in both H400 and BICR56 cancer cell lines but not in normal OKF6 cells. Remarkably, the same Kava constituents induced a significant reduction of OSCC cell migration and invasion. We have demonstrated, for the first time, that Kava constituents, FKA, FKB and yangonin have potential anticancer effects on OSCC. This highlights an avenue for further research of Kava constituents in the development of future cancer therapies to prevent and treat OSCC.

One way of trying to control oral squamous cell carcinoma is to invest in new therapies focused on the molecular biology of receptors and their intracellular signaling pathways. This study aimed to evaluate the effect of LY2109761 (an inhibitor of TGF-β receptors) on cell migration in oral squamous cell carcinoma in vitro. Actin cytoskeleton of SCC-4 cells control and LY2109761 (1, 5 and 10 μM) treated on three-dimensional Matrigel were analysed by using confocal laser microscopy. Control and LY2109761 (1, 5 and 10 μM) treated cells that migrated through the membrane of three-dimensional cell migration assays were counted, significance was p<0.05. Control cells were seen with voluminous cytoplasm, cell cortex preserved and actin cytoskeleton well developed with well distributed actin filaments. Regardless of concentration, cells treated showed: rounded morphology and small size, scanty cytoplasm, cortical F-actin less clear that the control cells, and disruption of actin filaments. The migratory cells were inhibited by treatment with LY2109761 [F (3, 11) = 3742, p<0.0001], in a dose-dependent manner. These results suggest that LY2109761 exerts an inhibitory effect on the actin cytoskeleton and cell migration on SCC-4 cells, therefore, it is a promising therapeutic option for oral squamous cell carcinoma.
