Identification of Telomerase-activating Blends From Naturally Occurring Compounds

Area of Science:

• Cellular Biology
• Biochemistry
• Aging Research

Background:

• Telomeres, DNA sequences at chromosome ends, shorten with cell division, limiting cellular lifespan.
• Telomerase, an enzyme, extends telomeres, potentially influencing cellular aging and health.
• Activating telomerase is a strategy to maintain telomere length and promote healthy aging.

Purpose of the Study:

• To investigate the effects of various natural compounds on telomerase activity.
• To assess telomerase activation in an in vitro model of cellular aging (IMR90 cells).
• To evaluate synergistic effects of compound blends on telomerase activity.

Main Methods:

• An in vitro study using IMR90 cells to model telomere shortening.
• Tested 12 single natural compounds and their blends for telomerase activity.
• Telomerase activity measured using TeloTAGGG telomerase polymerase chain reaction (PCR) enzyme-linked immunosorbent assay (ELISA).

Main Results:

• Several tested compounds demonstrated the ability to increase telomerase activity.
• Combinations of potent compounds significantly increased telomerase activity by 51%–290% compared to controls.
• The most potent blends showed potential in modulating cancer cell proliferation and enhancing chemotherapeutic effects.

Conclusions:

• Naturally occurring compounds can activate telomerase, with some exhibiting synergistic effects in blends.
• These telomerase-activating blends may offer health benefits, particularly for aging-related conditions.
• Further human studies are warranted to evaluate the safety and efficacy of these blends for telomere maintenance.
