Cancer patient sera increased BRCA1-KO fibroblasts growth. Cells were cultured for 2 weeks in control human serum, or cancer patient sera. Cell growth was then analyzed by counting the number of viable cells at every passage (5 days duration for every passage). a Line graph shows the population doublings capability and (b) column graph represents cumulative population doublings at the end of the treatment periods. Data are mean ± SD of 2 control sera vs. 6 cancer patient sera. (P = 0.027)
