Breakthrough study reveals how mutant p53 protein converts other proteins into cancer drivers

Instituto Nacional de Ciência e Tecnologia de Biologia Estrutural e Bioimagem (INBEB)
Peer-Reviewed Publication

Brazilian researchers from UFRJ and INBEB uncover how mutant p53, a key tumor suppressor, transforms proteins like p63 and p73 into cancer drivers via amyloid aggregation. Published in Communications Chemistry, the study also highlights heparin's potential to inhibit these harmful aggregates, offering a new approach for targeting aggressive cancers like glioblastoma. The findings open avenues for developing therapies to combat cancer at its molecular roots.
