For more than half a century, MYC has stood as one of cancer biology's most formidable enigmas — a master regulator implicated in the majority of human malignancies yet seemingly immune to the drugs that have transformed other cancers. Now, a team at Sanford Burnham Prebys has found that the answer was never hidden inside MYC itself, but in a neighboring stretch of chromosome 8 called PVT1, which encodes two previously unknown proteins — one that empowers MYC's destructive reach, and one that normally holds it in check. The discovery reframes a decades-old impasse not as a dead end, but as a d
