| Summary: | In the present study, the effect of ursolic acid benzaldehyde chalcone (UABC) on ovarian carcinoma cells was studied. The results revealed that ovarian carcinoma cells on UABC treatment increased Sub-G1 cell population, increased rate of cell apoptosis and morphological changes in mitochondrial membrane. In OVCAR 432 cells treatment with UABC increased the Sub-G1 cell population to 72.3% and growth inhibition rate of >72%. Treatment with 20 µM of UABC for 48 hours, led to an induction of apoptosis in 67.2% and induced morphological changes in OVCAR 432 cells. The Western blot results showed high concentration of cytochrome c in the cell cytosol after 48 hours of UABC treatment. Treatment of RMS-13 cells with UABC resulted in inhibition of GLI1, GLI2, PTCH1, and IGF2 genes. In addition, we found a significant reduction in hedgehog activity of RMS-13 cells after UABC treatment by means of a hedgehog-responsive reporter assay. Therefore, UABC can be a promising agent for the treatment of ovarian carcinoma.
