 Context examples: 

Subsequent lack of activation of guanylyl cyclase through nitric oxide results in decreased cyclic GMP (cGMP) levels, thereby inhibiting constriction of smooth muscle tissue, and decreased capillary permeability and histamine-activated allergic reactions.

This alters cell permeability and leads to growth inhibition.

Flavone acetic acid exhibits an antiproliferative effect on endothelial cells as a result of a superoxide-dependent mechanism, which induces changes in permeability of the vasculature of the tumor.

Bax, another Bcl-2 family member, is activated by this pathway to localize to the mitochondrial membrane and increase its permeability, releasing cytochrome c and other mitochondrial proteins.

Miltefosine targets cellular membranes, modulating cell membrane permeability, membrane lipid composition, phospholipid metabolism, and mitogenic signal transduction, resulting in cell differentiation and inhibition of cell growth.

Carbinoxamine diminishes the typical histaminergic effects on H1-receptors in bronchial smooth muscle, capillaries, and gastrointestinal smooth muscle, including vasodilation, bronchoconstriction, increased vascular permeability, pain, itching, and spasmodic contractions of gastrointestinal smooth muscle.

Doctor Osuna explains: These exosomes are also capable of affecting the permeability of membranes and the cytoskeleton, which facilitates the entry of molecules that would not normally have access.

By preventing NO generation, the vasodilatory effects of NO are abrogated leading to vasoconstriction, reduction in vascular permeability and an inhibition of angiogenesis.

Although its mechanism of action is unknown, pentosan polysulfate may act as a buffer to control cell permeability by preventing irritating solutes from reaching cells coated with it.
