OSK left in eyes for 21 months, no tumors
Mice had OSK gene therapy active in their eyes for 21 months with no tumor formation — in fact, treated mice had fewer tumors than untreated controls.

Exercise, Training, and Sinclair's Fitness Promise
At 1:58:47 · chapter starts 1:56:00
One of the episode's most entertaining threads is Rogan's ongoing gentle ribbing of Sinclair for not working out consistently, despite knowing all the science. Sinclair concedes he tells himself he's too busy, which he admits is 'bullshit.' Rogan offers his approach to onboarding sedentary people: start absurdly easy, build momentum, never leave exhausted. He cites Jelly Roll's 250-pound weight loss — started with just walking — as the template. Sinclair responds with his two-mode framework: the body toggles between abundance mode (meat, muscle-building, fast healing) and adversity mode (fasting, plant-based eating, exercise stress), and both are necessary for optimal health and longevity. The episode ends with a handshake deal — Sinclair will show up visibly fitter next appearance — and the promise that he'll try elk steak.
OSK Genes May Shrink Tumors and Fight Cancer
When OSK genes are switched on inside cancer cells and tumors, the cells 'wake up,' remember what they were supposed to be, and kill themselves. Treated mice had fewer tumors than untreated controls — a stunning side benefit of age-reversal therapy.
Harvard funding to longevity lab cut entirely
All federal funding to Sinclair's Harvard Medical School lab was cut during the Harvard-federal government dispute, nearly forcing him to fire most of his staff.
Harvard Funding Cut Almost Killed the Lab
When the federal government cut all funding to Harvard Medical School amid its political dispute with the White House, Sinclair nearly had to fire most of his staff. His lab now survives entirely on public donations — at a budget of just $3 million a year.
