Sinclair claims OSK ‘reprogramming’ shrank human tumours in mice in lab tests

Sinclair says a PhD student in his lab observed tumour shrinkage in mice after switching on the same three ‘OSK’ genes used in his age-reversal work, including in models described as human cancers growing in mice. He also says long-term exposure in mice did not increase tumours and may have reduced them, though he does not cite a publication or dataset during the episode.
