Fig. 7. Quantification of differential accumulation of p65-dsRed and
I
B
-EGFP in the nucleus following treatment of dual-transfected
cells with leptomycin B. (A) Cells transfected with p65-dsRed and
I
B
-EGFP were treated for 2 hours with 10 ng/ml LMB and monitored
by confocal microscopy. (B) Confocal microscopy of long term LMB-treated
cells. The top panel was treated for 8 hours with 10 ng/ml LMB. The bottom
panel was incubated with 10 ng/ml LMB followed 1 hour later by stimulation
with 10 ng/ml TNF
. The cells were then analysed for a further 8 hours
following TNF
stimulation.
