Poliovirus modulates Bcl-xl expression in the human U937 promonocytic cell line

Poliovirus modulates Bcl-xl expression in the human U937 promonocytic cell line Poliovirus induces bcl-2-independent apoptosis in the human U937 promonocytic cell line (28). Here we describe that this cell death, induced after viral infection, correlates with the modulation of the protooncoprotein Bcl-xl. Furthermore, poliovirus infection decreases the detected Bcl-xl in a U937 clone that overexpresses this protein (U937bcl-xl). Although in U937bcl-xl cells, Bcl-xl was not as highly regulated as in parental U937 cells, correlation between Bcl-xl modulation and the cleavage of poly(ADP-ribose)polymerase could be observed. Nevertheless, the induction of shutoff after infection of transfected control U937neo or U937bcl-xl clones was not significantly altered. Finally, production of new viral particles was slightly restricted in Bcl-xl-overexpressing U937 cells. Taken together, these results suggest that Bcl-xl is modulated during the induction of apoptosis in the promonocytic cell line U937 after poliovirus infection, although modulation of this protooncogene was not sufficient to modify the course of infection. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
