MDA-MB231 (A) and MCF7 (B) cells were used to prepare total homogenate (TH), microsomal fraction (MF) and the 1M KCl-stripped microsomal fraction (MF+1M KCl), as indicated under Figure 2. These fractions and the stripped MF plus 1.5 ng of recombinant Fra-1 or 1 ng of c-Fos/µg of TH were assayed for phospholipid synthesis capacity. Results are the mean cpm incorporated into phospholipids/mg protein ± SD of 3 experiments performed in triplicate. *: p<0.01.
