Firefox, a protein encoded by circular PVT1, is essential for MYC-driven oncogenesis.
MYC-driven (MYC+) cancers are highly aggressive and often fatal. MYC dysregulation is a key event in these cancers, yet MYC overexpression alone is often insufficient to initiate or sustain tumorigenesis. Plasmocytoma variant translocation 1 (PVT1), a long noncoding RNA (lncRNA) adjacent to MYC on chromosome 8q24, is f...
