[Peptidergic regulation of the expression of signal factors of fibroblast differentiation in the human prostate gland in cell aging]
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This cell-culture study (human prostate fibroblasts) examined effects of the short peptides T-32, T-38, and cardiogen on expression of differentiation signaling factors (CXCL12, WEDC1, and ghrelin) in aging fibroblast cultures. Using confocal laser microscopy, the authors reported that all three peptides increased expression of these markers, which had been reduced in senescent cultures, and that in older cultures (after 7 passages) expression under peptide treatment tended to exceed levels in younger cultures (after 1 passage). Peptide T-38 was reported as the most active of those tested. The authors described these findings as supporting further study of peptide regulation of prostate gland aging.
Abstract
The effect of short peptides T-32, T-38 and cardiogen on the expression of signaling factors of the differentiation of human prostate's fibroblasts (PFM), which are the main cells of its microenvironment--protein CXCL12, WEDC1 and ghrelin in aging cultures has been studied. Confocal laser microscopy has demonstrated that all the investigated peptides possess the ability to actively enhance the expression of the above markers, whose synthesis significantly reduced in senescent cultures. It has been shown that the rate of expression of the studied factors in older cultures (after 7 passages) under the action of the peptides have a tendency to even higher than those of controls (young culture, after 1 passage). Thus, peptide T-38 is the most active among the investigated ones. These studies show promise for detailed development of methods of peptides' regulation of aging and age-correction of violations of functioning of the prostate gland.
