Effects of Gynura procumbens leaves extract (GPE) on PTEN, EGFR, and TWIST gene expression in CHMp‐13a cells (a–c). Cells were treated with different concentrations (0, 40, 80, and 160 μg/ml) of GPE for 28 h. Relative abundance of mRNA was obtained by normalization to GAPDH expression. Each data point indicates the mean of six separate experiments ± SD. Statistical differences were analyzed using Kruskal Wallis followed by Dunn's multiple comparisons post hoc tests. Significant differences from the control are indicated: ^∗ p < 0.05; ^∗∗ p < 0.01
