Figure 2.
Results of UV-B irradiation on apoptosis in (A) NES-G2T and NES-B3T squamous cells and (B) BAR-T9 and BAR-T10 cells as determined by Annexin V staining. Note that UV-B irradiation at doses of 50 and 100 J/m2 did not induce apoptosis in the Barrett's cells. The bar graphs depict the mean + SEM of at least 3 individual experiments. (NES-G2T: *, p<0.001 compared to non-irradiated controls; +, p<0.001 compared to 50 J/m2; #, p<0.01 compared to 100 J/m2, @, p<0.01 compared to 200 J/m2; NES-B3T: *, p<0.001 compared to non-irradiated controls; +, p<0.001 compared to 50 J/m2; #, p<0.001 compared to 100 J/m2, @, p<0.001 compared to 200 J/m2; BAR-T9 and BAR-T10: *, p<0.001 compared to non-irradiated controls; @, p<0.001 compared to 200 J/m2)
