Normal induction of c-myc transcription in CpG-stimulated BCR^neg B cells. Sorted BCR^pos and BCR^neg B cells generated by TAT-Cre transduction from B1-8^f/+, bcl-2tg mice were stimulated for 3 h with medium or CpG. cDNA from purified RNA was used for quantitative RT-PCR analysis of c-myc and hprt expression. Data for two biologically independent experiments (average of technical duplicates shown for each biologically independent experiment) represent fold-change of c-myc expression relative to BCR^pos B cells cultured in medium.
