Enhanced uptake of antisense oligonucleotides using cationic liposomes and the apoptotic effect of idarubicin in K-562 cell line.


We have evaluated the apoptotic and DNA damaging activity of Idarubicin (IDA) on K-562 cells alone and following the uptake of modified antisense-oligodeoxynucleotides (AS-ODNs) targeting b3a2 mRNA of bcr/abl hybrid gene, after treatment with AS-ODNs/DCChol-DOPE (liposomes) complexes. The uptake of FITC-labeled oligonucleotide-liposomes complexes (FITC-ODNs… (More)
