Randomized trial demonstrates tumor suppression in HPV-positive cancers through E6 inactivation, indicating a promising treatment strategy.

This research aims to explore the therapeutic potential of covalent inhibitors targeting HPV-16 E6 to restore p53 function and suppress tumor growth.
Identified a covalent inhibitor that targets a specific cysteine in HPV-16 E6 protein.
Conducted experiments on HPV-16 positive cancer cells to assess p53 restoration and tumor suppression.
Utilized xenograft models to evaluate the in vivo effects of E6 inactivation on tumor growth.
Restoration of p53 protein stability and activity led to apoptosis in HPV-16 positive cancer cells.
In vivo, E6 inhibition suppressed tumor growth with minimal toxicity and no resistance observed.
Transcriptomic profiling confirmed activation of p53-dependent tumor suppressor programs post-E6 inhibition.
