  Effects of Bcl-2 modulation with G3139 antisense oligonucleotide on human breast cancer cells are independent of inherent Bcl-2 protein expression

  摘要：

  We have investigated the effects of transient Bcl-2 down-regulation induced by the Bcl-2 antisense oligodeoxynucleotide (ODN) G3139 (Genta Incorporated) in high Bcl-2 protein expressing, estrogen receptor (ER) positive MCF-7 and low Bcl-2 expressing, ER negative MDA435/LCC6 human breast cancer cells. Treatment with Bcl-2 antisense ODN in vitro caused > 80% reduction of Bcl-2 protein levels in a sequence specific manner for both cell lines. Maximum mRNA reduction was achieved within 24 h of the first antisense ODN exposure whereas full protein down-regulation required antisense exposure over 48 h. This Bcl-2 reduction was associated with 80-95% loss of viable cells compared to untreated cells. Similar cytotoxic effects were observed in both cell lines despite a nine-fold intrinsic difference in Bcl-2 protein expression suggesting that the relative degree of down-regulation of Bcl-2 is more important than the absolute reduction. Cell death associated with G3139 exposure exhibited properties indicative of apoptosis such as mitochondrial membrane depolarization and caspase activation. Combined treatment with G3139 and cytotoxic agents resulted in additive cytotoxicity in both cell lines. However, under most conditions studied, the direct cytotoxic activity of G3139 antisense was not synergistic with the cytotoxic agents. These results suggest that while Bcl-2 clearly constitutes an attractive therapeutic target due to its role in regulating apoptosis in breast cancer cells, additional mechanisms are important in the control of apoptosis arising from exposure to anticancer agents in vitro.
