Cellular uptake mechanism and comparative in vitro cytotoxicity studies of monomeric LMWP-siRNA conjugate

The covalent attachment of CPPs to siRNA molecules offers great potential for CPP-mediated siRNA delivery. We recently reported a concise and high-yield synthesis strategy of the cell-permeable, cytosol-dissociable LMWP-siRNA covalent conjugate. Herein, cell uptake mechanism and cellular toxicity studies of this conjugate were performed to evaluate the potential of LMWP-siRNA conjugate for clinical translation. Cellular uptake mechanism study...
