Anti-ageing properties of Khelma Longevity™: treatment of human fibroblasts increases proteasome levels and decreases the levels of oxidized proteins

In vitro pilot study indicates that Khelma Longevity™ is a potent proteasome activator demonstrating clear anti-ageing properties. The proteasome is a multisubunit enzyme complex that plays a central role in the regulation of proteins that control cell-cycle progression and apoptosis. Protein degradation by proteasomes plays a major role in the regulation of a wide range of basic cellular processes.

The study is published in 25 September 2017 in  New Biotechnology, special issue in memory of professor Brian F.C. Clark (1936-2014) : New Biotechnology is the official journal of the European Federation of Biotechnology (EFB).

The study, determined the putative anti-ageing properties of Khelma Longevity™, a formula based on various natural compounds from the Mediterranean area. Human primary fibroblast cultures were treated with a wide range of concentrations of Khelma Longevity™ for 1 day or 3 consecutive days. Following these treatments, two major and complementary biomarkers of ageing were measured, namely, the proteasome and the amount of oxidized proteins. It was observed that 24 h of treatment with Khelma Longevity™ resulted in a maximum increase of about 41% of the total protein levels of 20S proteasome. Levels of oxidized proteins were reduced by almost 6.5-fold following longer treatments. Specifically we have observed a maximum decrease of protein carbonyls to 84.7% in comparison with nontreated control cells following 3 days of continuous treatment with Khelma Longevity™. These results support the notion that formulas rich in natural compounds from the Mediterranean area possess anti-ageing properties.
