Telomerase reverse transcriptase (TERT) protein is not shared outside the cell.

"Telomerase reverse transcriptase is not shared outside the cell. So, we needed to hit as many of the cells as we possibly could" (said at 0:00:15)

No published record matching the claim that telomerase reverse transcriptase (TERT) protein is not shared outside the cell was located; this does not prove the claim false.

Approximately 36 million people die globally each year from biological aging.

"36 million people will die this year of biological aging." (said at 0:20:43)

No published record matching the claim that approximately 36 million people die globally each year from biological aging was located; this does not prove the claim false.

A clinical study administering dual Klotho and TERT gene therapy to dementia patients resulted in lengthened immune system telomeres and improved cognitive scores lasting nearly two years.

"Neurocognitive—we released a paper years ago that was the first dementia study with gene therapy in the entire world, where we used Klotho and telomerase reverse transcriptase to see improved cognition in those patients. And this tiny amount of TERT actually made their immune system telomeres longer." (said at 0:23:18)

No published record matching a clinical study administering dual Klotho and TERT gene therapy to dementia patients that resulted in lengthened immune system telomeres and improved cognitive scores was located; this does not prove the claim false.

An autopsy study found that individuals who had hallmarks of Alzheimer's disease but no cognitive impairment had natural upregulation of alpha-Klotho.

"Upon autopsy, patients who had all of the signs of Alzheimer's, uh, the beta-amyloid plaques and and the shrinkage of the brain, who didn't have cognitive issues, did not show the cognitive symptoms of the disease, were all natural alpha-Klotho upregulators." (said at 0:30:51)

No published record matching the claim that an autopsy study found individuals with severe Alzheimer's neuropathology who remained cognitively intact were all natural upregulators of alpha-Klotho was located; this does not prove the claim false. While the KLOTHO longevity gene and the KL-VS heterozygote variant have been investigated for potential neuroprotective associations against cognitive decline and Alzheimer's biomarkers in living cohorts, no autopsy study establishing universal alpha-Klotho upregulation in asymptomatic individuals with full Alzheimer's pathology was identified.

A patient with chronic kidney disease awaiting a kidney transplant received image-guided Klotho gene therapy directly to the kidney and was able to come off the transplant donor list for two years.

"we had a patient who was on the um donor list uh on the list to get a donation of a kidney uh and had to and immediately needed one and he took the gene therapy directly image-guided gene therapy to the kidney. He came off the list for two years" (said at 0:50:20)

No published record matching a chronic kidney disease patient receiving image-guided Klotho gene therapy directly to the kidney and coming off a transplant donor list was located; this does not prove the claim false. While preclinical animal models and in vitro studies have investigated Klotho delivery for kidney injury and fibrosis, no published clinical trials or peer-reviewed case reports document this human clinical outcome.

Approximately 110,000 people worldwide die every day from biological aging.

"Because today 110,000 people will die of biological aging" (said at 0:54:20)

No published record matching the claim that approximately 110,000 people die every day from biological aging was located; this does not prove the claim false.

In 2024, the Bahamas passed a law allowing clinical trials using gene therapy to treat biological aging.

"And in 2024, we worked really hard and the Bahamas passed a law to do such things. And they will be running clinical trials, as as you would expect, to get these drugs into the US FDA regulatory system." (said at 1:01:53)

No published record matching the claim that the Bahamas passed a law in 2024 allowing clinical trials using gene therapy to treat biological aging was located; this does not prove the claim false.

Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
