| 摘要 |
This invention provides compositions and methods to identify candidate agents capable of altering the biological activity of a polypeptide encoded by a polynucleotide involved in hypoxia-related tumorigenesis. In one aspect, the biological activity is the induction of hypoxia-related gene enolase 2 or a biological equivalent thereof. In another aspect, the biological activity is the induction of a hypoxia-related gene, inducible in the absence of the von Hippel-Lindau tumor suppressor (VHL). In yet a further aspect, the biological activity is differential expression in a neoplastic cell under hypoxia. In an alternative aspect, the biological activity is induction of a gene that is inducible in the absence of VHL, but not hypoxia.
