Genetic engineering of proteins with cell membrane permeability

Nature Biotechnology, 1998
The discovery of methods for generating proteins with inherent cell membrane-translocating activity will expand our ability to study and manipulate various intracellular processes in living systems. We report a method to engineer proteins with cell-membrane permeability.

Asymmetrically Permeable Membrane Channels in Cell Junction

Science, 1980
Asymmetric membrane junctions were formed in culture by pairing two cell types which, in their respective homologous junctions, have cell-cell channels of different permselectivities. The channels in the asymmetric junction, presumably made of unequal channel precursors, displayed directional permselectivity; fluorescent labeled glutamic acid (700 ...

Membrane permeability equations and their solutions for red cells

The Journal of Membrane Biology, 1977
The mathematical equations for the transport of nonelectrolytes across cell membranes are critically examined and cast in forms suitable for solution which involve fewer approximations than has heretofore been commonly done. For the use of red cells, the equations are developed to include the effect of the variation in apparent nonosmotic water owing ...

Cell membrane permeability in hypertension.

Clinical physiology and biochemistry, 1989
A great deal of evidence has been presented which suggests that a generalized increase in cell membrane permeability to various ions is a fundamental defect associated with hypertension. In addition, some of the evidence is supportive of a central role of this defect in the pathogenesis of hypertension.

Membrane permeability of isolated lung cells to nonelectrolytes

American Journal of Physiology-Cell Physiology, 1977
Mixtures of viable endothelial and epithelial cells were separated by enzymatic digestion from rabbit lung and recovered by centrifugation. The cells were mixed with an extracellular marker and packed by centrifugation into small-diameter polyethylene tubing and pulsed with tritiated water and 14C-labeled alcohols.

Cell Membrane Permeability and Hypertension

1984
A great deal of evidence has been presented which suggests that a generalized increase in cell membrane permeability to various ions is a fundamental defect associated with hypertension. In addition, some of the evidence is supportive of a central role of this defect in the pathogenesis of hypertension.

The Cell Membrane and Ionic Permeability

1991
All living cells are surrounded by a cell membrane which separates the cellular contents from the outside medium. The organized contents of the cell, including the nucleus and such organelles as the mitochondria, Golgi apparatus, lysosomes, the endoplasmic reticulum, as well as the components of the cytoskeleton, exist in a watery medium — the ...

The Nanopore Connection to Cell Membrane Unitary Permeability

Traffic, 2005
Artificial nanopores have recently emerged as versatile tools for analyzing and sorting single molecules at high speed. However, the biological cell has already developed a large set of sophisticated protein nanopores that are able to selectively translocate all types of molecules through membranes.
