FIG. 9.

Effect of GSTμ on 32D/c-myb p75 and p89 cells. (A) 32D/c-myb p89 cells were transfected with GSTμ antisense oligodeoxynucleotides (ODN1 and ODN2) and a nonspecific oligonucleotide (cntrl). At 3 h following transfection, the cells were washed in IL-3-free medium and incubated for 3 days. At each indicated time point, the cells were analyzed for viability by trypan blue exclusion. The curves represent means of three experiments. (B) 32D/c-myb p75 cells were transfected either with an empty vector or with the GSTμ expression vector, and stable transfectants were selected (GSTμ/1 and GSTμ/2). Cells were washed in IL-3-free medium and incubated for 3 days. At each indicated time point, the cells were analyzed for viability by trypan blue exclusion. The curves represent means of three experiments.
