Figure 4From: Mechanisms of increased risk of tumorigenesis in Atm and Brca1 double heterozygosityTotal DNA damage measured with alkaline comet assay in four kinds of MEF cells at different time course. Data were a pool of three independent experiments and totally 200 cells were scored. * and ** indicate the significant difference compared with ATMwt/BRCA1wt cells experienced the same treatment and same post-incubation (* for p < 0.05 and ** p < 0.01).Back to article page
