[Enhancement of Vp16 inducing apoptosis of leukemic cells by retrovirus-mediated bcl-2 anti-sense RNA].
OBJECTIVE
To explore the effects of retrovirus-mediated bcl-2 antisense RNA on apoptosis of leukemic cells.


METHODS
Retrovirus was packaged in vitro with PA317 cells and Jurkat cell was transducted with collected virus; The expressions of bcl-2 mRNA and protein were assayed by RT-PCR and Western blotting, respectively. Apoptosis was assayed by flow cytometry and DNA "ladder".


RESULTS
Expression of intrinsic bcl-2 was decreased, and the sensitivity of leukemic cells to Vp16 and the apoptosis of leukemic cells line Jurkat cells were enhanced by transfected bcl-2 antisense RNA.


CONCLUSIONS
Antisense bcl-2 enhances Vp16 inducing apoptosis of leukemic cells. The results provide a useful experimental basis for leukemia therapy.
