[Biological activity of regulatory peptides in model experiments in vitro]
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this in vitro study using human materials, the authors examined biological effects of the short regulatory peptides pinealon, vesugen, vilon, and epitalon. The abstract reports that the peptides did not demonstrate direct antioxidant activity but were able to restrict lipid peroxidation of human lipoproteins by modifying their structure. The peptides were reported to increase the stability of red blood cell membranes toward osmotic hemolysis, to elevate the stationary level of intracellular reactive oxygen species, and at the same time to decrease (all except epitalon) the percentage of dead cells in a neuronal population. The authors suggest that under in vivo conditions the short peptides may participate in apoptosis/necrosis regulation. No numerical figures were given in the abstract.
Abstract
Biological effects of short regulatory peptides, pinealon, vesugen, vilon and epitalon were studied in model experiments in vitro. These peptides were found not to demonstrate direct antioxidant activity but be able to restrict lipid peroxidation of human lipoproteins by modification of their structure. The short peptides increase stability of red blood cell membranes toward osmotic hemolysis. They also elevate the stationary level of intracellular reactive oxygen species and at the same time decrease (all excepting epitalon) percent of dead cells in neuronal population. The suggestion was made that under in vivo conditions, short peptides may participate in apoptosis/necrosis regulation.
