Figure 7. Polar effects by Tat on the apical and basolateral side of the Caco-2 cell monolayers.

Figure 7

Tat was added to apical or basolateral side of Caco-2 cell monolayers and GSH (grey)/GSSG (white) ratio (A) and caspase-3 activation (B) were evaluated after 1, 24 and 48 hours. *p<0,05 vs control; #p<0,05 vs apical Tat stimulation at the same time. Normalization of western blot was performed with GAPDH in all experiments. Densitometric acquisitions are shown from three representative separate experiments.
