Cell viability was measured using MTT assay a CTN treatment with 0–100 μM CTN concentration for 24 h, b cells were pretreated with GTE (20, 40, 80 µg/ml) for 2 h followed by with or without CTN (100 µM) treatment for 24 h. Data are expressed as the mean ± standard deviation from three independent experiments, each performed in triplicate. *p < 0.05 versus control cells, ^# p < 0.05 versus CTN treated cells
