Figure 1From: Effects of Coptis extract combined with chemotherapeutic agents on ROS production, multidrug resistance, and cell growth in A549 human lung cancer cellsEffects of COP and BER on the growth of A549 cells. A. Morphological changes of A549 cells treated with 6.4 μg/mL COP or 4.0 μg/mL BER for 72 h under inverted phase contrast microscope (200 ×). B. Treatment with COP and BER for 72 h inhibited A549 cell growth (P < 0.01) [Pearson Correlation Test, P = 0.0032 for COP; P = 0.0178 for BER] in a dose-dependent manner. Values are means ± SD of 4 independent assays.Back to article page
