Hypoxia as a regulator of tumor stroma and metastasis
Kyoung Eun Lee
Abstract
Metastasis is the leading cause of mortality in most patients with cancer. Despite its clinical importance, mechanistic underpinnings of metastatic progression remain poorly understood. Hypoxia, a condition of insufficient oxygen availability, frequently occurs in solid tumors because of their high oxygen/nutrient demand and abnormal tumor vasculature. In this review, we describe the roles of hypoxia and hypoxia-inducible factor (HIF) signaling in the metastatic cascade, with an emphasis on recent biological insights from in vivo studies.
