Fig. 5From: The Small GTPase Rac Suppresses Apoptosis Caused by Serum Deprivation in FibroblastsTranscriptional activity of NF-κB is stimulated by expression of either Rac1V12 or Rac1N17. Mutant Rac1-expressing cell lines were transfected with the NF-κB-dependent E-selectin luciferase reporter and subsequently maintained in the presence or absence of serum as described in Materials and Methods. Data shown are the mean ± SEM of four experiments.Back to article page
