The Cys2/His2-type zinc finger protein Zfp296 has been implicated in stem cell pluripotency and tumor pathogenesis.However, its mechanisms remain elusive.
The fact that we never observed amplification of HST & INT-2 independently of BCL-1, which in turn can be amplified solely, suggests the presence, between HST/INT-2 and BCL-1, of a genetic element which could be important in the development of a subset of mammary tumors.
The use of artificial transcription factors based on Cys2-His2 zinc-finger proteins (ZFPs) targeting the VEGF promoter offers a novel strategy for modulating VEGF levels in tumors.
