Description:

WARNING: This product is for research use only, not for human or veterinary use.

TAC-activator, also known as TAC, is a TERT activator compound (TAC). TAC could therapeutically restore the ‘youthful’ levels of a specific subunit of the telomerase enzyme, and could significantly reduce the signs and symptoms of aging in preclinical models. TAC improved neuromuscular function, coordination, grip strength and speed in these models, reversing sarcopenia – a condition under which muscle mass, strength and performance naturally worsen with advancing age. TAC treatment in human cell lines increased telomere synthesis with reduced DNA damage signal at telomeres and extended the proliferative potential of these cells, demonstrating the activity of TAC in ex vivo human models. TAC-activator may have therapeutic implications for age-related diseases such as Alzheimer’s, Parkinson’s, heart disease and cancer.

More Info
TAC was first reported by Researchers at The University of Texas MD Anderson Cancer Center. The enzyme telomerase can prevent telomere attrition from happening by extending the length of telomeres. However, in most multicellular organisms, including humans, telomerase expression is switched off, except in germ cells, some types of stem cells, and certain white blood cells. While this might play a role in preventing cancer, as most cancerous cells must switch telomerase expression back on via mutations to enable runaway replication, numerous studies have shown that increasing telomerase through TERT delays aging and increases longevity of model organisms. Aging is associated with various epigenetic changes that influence functional and physiological decline. One of the hallmarks of aging is the gradual shortening of telomeres, the chromosomal end structures that help maintain their stability. Free radicals also can modify and harm telomere sequences. When telomeres become extremely short or modified, they trigger a continual DNA damage response, which can lead to cell senescence – a phenomenon in which cells release inflammatory factors that can cause tissue damage, prompting aging and cancer. Telomerase is a protein complex responsible for synthesizing and extending telomeres. However, its activity is reduced over time due to the epigenetic silencing of TERT, particularly at the onset of natural aging or Alzheimer’s and other age-related diseases. TAC treatment also significantly reduced inflammaging -- an age-related increase in inflammatory markers linked with multiple diseases -- in both blood and tissue samples and also eliminated senescent cells by repressing the p16 gene, a key senescence factor.
