Regulation of various proteins by Fn and PLL treatments.

(A) Nalm-6 cells were cultured with Fn or PLL for 0.5, 1 or 2 days, in absence of serum. An aliquot of each cell lysate was then analyzed by Western blot using anti–FBI-1 and after stripping with anti-GAPDH antibodies. (B) Nalm-6 cells were cultured with Fn or PLL for 1, 2, 3 or 6 days without serum before lysis. An aliquot of each cell lysate was then analyzed by Western blot using anti–c-Fos and anti-GAPDH antibodies. (C) An aliquot of each cell lysate listed in the legend to panel B was analyzed by Western blot using anti-CD79A and anti-GAPDH antibodies.
