Figure 2From: 4β-Hydroxywithanolide E from Physalis peruviana (golden berry) inhibits growth of human lung cancer cells through DNA damage, apoptosis and G2/M arrest Comet-NE assay of 4βHWE in H1299 cells. (A) PI staining for cell controls (DMSO) and 4βHWE-treated cells (1, 5, and 10 μg/mL, 2 h). The circular spots in pink were nuclei; the tails indicated the DNA damage. (B) Average of % tail DNA for 4βHWE-treated cells.Back to article page
