KLOTHO NEUROSCIENCE, INC. ANNOUNCES AN APPROACH TO INCREASE LONGEVITY AND HEALTHY LIFE SPAN - REPLACE A SILENCED GENE CALLED ALPHA-KLOTHO ("α-KLOTHO")

Rhea-AI Summary

Klotho Neurosciences (NASDAQ: KLTO) has announced breakthrough findings in longevity research centered on the Klotho gene. The company has secured exclusive worldwide licenses for s-KL protein technology, building on Professor Makoto Kuro-O's 1997 discovery linking Klotho blood levels to mammalian lifespan. Recent studies published in Molecular Therapy demonstrated that genetic overexpression of Klotho increased mouse lifespan by 30-40%, while the secreted form (s-KL) showed a 20% lifespan increase.

Insights

Biotechnology Research Analyst

Klotho Neuroscience reports promising pre-clinical results for their anti-aging protein s-KL, potentially extending lifespan by 20% with multiple disease applications.

Klotho Neuroscience (NASDAQ: KLTO) has announced compelling pre-clinical evidence supporting their focus on the α-Klotho gene for extending lifespan and improving healthspan. The research builds upon pioneering work by Professor Makoto Kuro-O, who demonstrated that Klotho blood levels directly correlate with mammalian lifespan, with genetic overexpression extending mouse lifespan by 30-40%.

The company highlighted recent findings published in Molecular Therapy (February 2025) showing their secreted Klotho protein (s-KL) delivered via AAV9 vector increased mouse lifespan by 20%. What's particularly noteworthy is the protein's multi-system impact on age-related conditions including cognitive decline, neuroinflammation, sarcopenia, and osteoporosis—suggesting a single therapeutic approach might address multiple aspects of aging simultaneously.

From a strategic perspective, KLTO has secured a formidable intellectual property position with exclusive worldwide licensing for s-KL from Universitat Autònoma de Barcelona and Institució Catalana de Recerca i Estudis Avançats, with patents issued across the US, Europe, and China. Having Professor Kuro-O as a scientific advisor strengthens their scientific credibility.

The company is specifically targeting neurodegenerative diseases including ALS, Alzheimer's, and Parkinson's—representing massive market opportunities with significant unmet needs. While these results remain pre-clinical, the mechanistic approach targeting fundamental aging processes rather than just symptoms shows scientific sophistication. The multi-organ benefits suggest potential applications beyond neurodegeneration into broader anti-aging therapeutics—a rapidly growing market segment.

Recent clinical and pre-clinical studies and analysis indicates the potential to increase lifespan and reduce age-associated degeneration in multiple organ systems has be realized with a focus on the human gene called Klotho.

NEW YORK, June 9, 2025 /PRNewswire/ -- Klotho Neurosciences, Inc. (NASDAQ: KLTO), a U.S.-based biogenetics company announced the findings of pre-clinical studies indicating the potential of elevating Klotho gene expression to simultaneously reduce the age-associated degeneration in multiple organs, increasing both life and health span.

Pioneering discoveries by Professor Makoto Kuro-O in 1997 showed that Klotho concentrations in the blood were directly associated with lifespan of mammals – the lower the Klotho blood levels the shorter the lifespan. Kuro-O's laboratory then published the first evidence that genetic over expression of the full-length form of Klotho in mice, increased in lifespan of mice of up to 30%-40% longer compared to the normal mouse lifespan. Since then, the Klotho protein has gained much attention because of its ability to influence key biological pathways involved in metabolism, inflammation and tissue repair, which are closely linked to the aging process.

A series of experiments led by Joan Roig-Soriano and colleagues, published in the February 2025 edition of Molecular Therapy, highlights the promising role of the naturally occurring secreted form of the Klotho protein ("s-KL") and its effects on healthy aging mice and mice with a rapidly aging phenotype. Key observations were that, while aging is a major risk factor for many pathologies, including cognitive decline, neuroinflammation, sarcopenia, and osteoporosis, the secreted protein s-KL has emerged as a potentially promising therapeutic anti-aging molecule due to its many biological effects involving multiple pathways related to cell injury, stress, and inflammation. The s-KL was administered using an adeno-associated virus serotype 9 delivery vector (AAV9) that expressed the secreted KL protein isoform and efficiently increased the concentration of s-KL in serum, resulting in a 20% increase in lifespan.

Dr. Joseph Sinkule, the CEO of Klotho Neurosciences (KLTO) commented that "KLTO has secured an exclusive worldwide license for s-Kl from Universitat Autònoma de Barcelona (UAB) and Institució Catalana de Recerca i Estudis Avançats (ICREA) in Spain. As a result, we have the exclusive use of patents issued in the USA, Europe, and China covering a secreted splice variant of mammalian Klotho referred to as s-KL, as a treatment for neurodegenerative and age -related disorders. Professor Makoto Kuro-O is also a scientific advisor to KLTO. This recently published paper provides further credence to our development of s-KL as a treatment to reduce age-associated degeneration where, as a company, KLTO has a particular focus on neurodegenerative diseases such as ALS, Alzheimer's and Parkinson's disease. The results disclosed in the paper show the potential of elevating s-KL protein expression, resulting in the reduction of age-associated degeneration in multiple organs, increasing both life and health span".
