Bcl-2 antisense oligonucleotide inhibits the proliferation of childhood leukemia/lymphoma cells of the B-cell lineage.
An 18-mer phosphorothioate bcl-2 antisense oligonucleotide (ASO) inhibited colony formation of three B-cell leukemia/lymphoma cell lines in a dose dependent manner in the range of 0.125-0.5 micromol/l. The scrambled cogener had no detectable effect. A decrease in BCL-2 protein and apoptotic DNA fragmentation was detected in the studied cell lines and primary blast cells of two children with acute lymphoblastic leukemia. Neither BCL-2 protein level, nor DNA integrity was affected by the scrambled control indicating the specific effect ASO. As far as we know, this is the first report on the effects of bcl-2 ASO on childhood leukemia/lymphoma cell samples.
