Methods of promoting uptake and nuclear accumulation of polyamides in eukaryotic cells

摘要

A method for enhancing cellular uptake and redistributing gene regulating polyamides from the extranuclear areas in eukaryotic cells to the nucleus thereof. The method consists of administering to the eukaryotic cells a molecular trafficking compound. The administered molecular trafficking compound affects cellular pathways and mechanisms that accumulate polyamides in cytoplasmic vessicles and/or efflux polyamides from the intracellular regions of cell. The method also includes modifying polyamides to contain negatively-charged or acidic moieties wherein the moieties inhibit the accumulation of polyamides in cellular lysosomes. By affecting the cellular pathways and mechanisms, the polyamides are redistributed throughout the cell, whereby nuclear accumulation of the polyamides is enhanced.
