Growth inhibitory effect of YK on different cell lines. A. HEK293T, A549, HepG2, Hela, IHH and SKOV6 cells were treated with different doses of YK (1, 10, 100 μg/ml) and analyzed for cell viability by MTT assay. B. SKOV6 cells was treated with YK and/ or paclitaxel (10 nM) and the cell viability was measured as above. Results are represented as mean of three independent experiments ± S.E.M. Level of significance; *, p <0.005.
