Table 1. Micronuclei (MNi) formation in the HAC/BRCA1-containing UWB1.289 cells and in the same cells that have lost the HAC.

Experiment No Mni Mni Total %Mni Mean ± SD (%)**
BRCA1 positive (A)* 155 53 208 25.5 24.7±1.1
BRCA1 positive (B) 156 49 205 23.9
BRCA1 negative (A) 129 81 210 38.6 38.5±0.1
BRCA1 negative (B) 125 78 203 38.4

A, the first experiment; B, the second experiment.

**Number of MN is given as means ± SD in two independent experiments. There is a significant difference between BRCA1 positive and BRCA1 negative cells [χ2 (1) = 18.20, P < 0.0001].
