We investigated the effect of glucose deprivation treatment on clonogenicity in multidrug-resistant human breast carcinoma MCF-7/ADR cells. Survival of MCF-7/ADR cells decreased exponentially up to 8 hours of incubation in the glucose-free medium. The surviving fraction of these cells for 8 hours of glucose-deprivation treatment was 1.5 x 10(-3). Photomicrographs and gel electrophoresis data suggest that glucose deprivation-induced cell death is associated with apoptosis. Data from western and northern blots showed an induction of c-myc gene expression during treatment with glucose-free medium in MCF-7/ADR cells. MCF-7/ADR cells transfected with c-myc antisense oligodeoxynucleotides became resistant to glucose deprivation-induced apoptosis. Overexpression of bcl-2 gene protected MCF-7/ADR cells from this apoptotic cell death. Taken together, these results indicate that c-myc expression is a necessary component of glucose-free medium induced apoptosis and bcl-2 prevents apoptotic death induced by c-myc.
