Recent progress in the study on antitumor drugs targeting hypoxia-inducible factor-1 / 药学学报

ABSTRACT

Hypoxia-inducible factor-1 (HIF-1), as a transcription factor, plays an important role in the adaptation to hypoxic microenvironment within tumors. It can induce a series of genes transcription that participate in angiogenesis, glucose metabolism, cell proliferation, and cell migration/invasion. Thus HIF-1 not only allows cancer cells to survive in hypoxic microenvironment, but also makes the tumor more aggressive. Moreover, HIF-1 also induces tumors to acquire resistance to chemo-/radio-therapy, and is related to poor prognosis. HIF-1 emerges gradually as a potential target to develop new antitumor drugs. This paper reviews recent progress in this field.
