pubmed:abstractText |
We have investigated the interaction of oligonucleotides and their alkylating derivatives with mammalian cells. In experiments with L929 mouse fibroblast and Krebs 2 ascites carcinoma cells, it was found that cellular uptake of oligodeoxynucleotide derivatives is achieved by an endocytosis mechanism. Uptake is considerably more efficient at low oligomer concentration (less than 1 microM), because at this concentration a significant percentage of the total oligomer pool is absorbed on the cell surface and internalized by a more efficient absorptive endocytosis process. Two modified proteins were detected in mouse fibroblasts that were treated with the alkylating oligonucleotide derivatives. The binding of the oligomers to the proteins is inhibited by other oligodeoxynucleotides, single- and double-stranded DNA, and RNA. The polyanions heparin and chondroitin sulfates A and B do not inhibit binding. These observations suggest the involvement of specific receptor proteins in binding of oligomers to mammalian cells.
