Figure 6

Accumulation of HaCaT cells in S phase following NG treatment. Cells were grown to 60–70% confluency, unirradiated or irradiated with 15 mJ cm−2 UVB followed by incubation with or without 10 µm NG. Six hours later, cells were trypsinized, stained with propidium iodide and analyzed for DNA content using flow cytometry. The percentage of cells in the G1 (A), S (B), G2/M (C) phases was calculated using ModFit computer software. *Shows significant difference from UV-treated cells at P < 0.05.
