pH-(low)-insertion-peptide (pHLIP) translocation of membrane impermeable phalloidin toxin inhibits cancer cell proliferation.
We find that pH-(low)-insertion-peptide (pHLIP)-facilitated translocation of phalloidin, a cell-impermeable polar toxin, inhibits the proliferation of cancer cells in a pH-dependent fashion. The monomeric pHLIP inserts its C terminus across a membrane under slightly acidic conditions (pH 6-6.5), forming a transmembrane helix. The delivery construct carries phalloidin linked to its inserting C t...
متن کاملAntiproliferative effect of pHLIP-amanitin.
Toxins could be effective anticancer drugs, if their selective delivery into cancer cells could be achieved. We have shown that the energy of membrane-associated folding of water-soluble membrane peptides of the pHLIP (pH low insertion peptide) family could be used to move cell-impermeable cargo across the lipid bilayer into the cytoplasm of cancer cells. Here we present the results of a study ...
متن کاملDifferentiation of Umbilical Cord Lining Membrane-Derived Mesenchymal Stem Cells into Endothelial-Like Cells
Background: Stem cell therapy for the treatment of vascular-related diseases through functional revascularization is one of the most important research areas in tissue engineering. The aim of this study was to investigate the in vitro differentiation of umbilical CL-MSC into endothelial lineage cells. Methods: In this study, isolated cells were characterized for expression of MSC-specific marke...
متن کاملSeeing the electroporative uptake of cell-membrane impermeable fluorescent molecules and nanoparticles.
This paper presents direct visualization of uptake directionality for cell-membrane impermeant fluorescent molecules and fluorescence-doped nanoparticles at a single-cell level during electroporation. To observe directly the uptake direction, we used microchannel-type electroporation that can generate a relatively symmetric and uniform electric field. For all the image frames during electropora...
متن کاملOuter-membrane translocation of bulky small molecules by passive diffusion.
The outer membrane (OM) of gram-negative bacteria forms a protective layer around the cell that serves as a permeability barrier to prevent unrestricted access of noxious substances. The permeability barrier of the OM results partly from the limited pore diameters of OM diffusion channels. As a consequence, there is an "OM size-exclusion limit," and the uptake of bulky molecules with molecular ...
