Journal ArticleDOI
HIF-1 mediates adaptation to hypoxia by actively downregulating mitochondrial oxygen consumption
TL;DR: It is shown by genetic means that HIF-1-dependent block to oxygen utilization results in increased oxygen availability, decreased cell death when total oxygen is limiting, and reduced cell death in response to the hypoxic cytotoxin tirapazamine.
Journal ArticleDOI
Hypoxia signals autophagy in tumor cells via AMPK activity, independent of HIF-1, BNIP3, and BNIP3L.
TL;DR: Findings suggest that the autophagic degradation of cellular macromolecules contributes to the energetic balance governed by AMPK, and that suppression of autophagy in transformed cells can increase both resistance to hypoxic stress and tumorigenicity.
Journal ArticleDOI
Cellular reaction to hypoxia: sensing and responding to an adverse environment
TL;DR: As more is understood about the hypoxic response, it is realized how it can impact normal development, wound healing, and the malignant progression of a solid tumor.
Journal ArticleDOI
Tumor Hypoxia Blocks Wnt Processing and Secretion through the Induction of Endoplasmic Reticulum Stress
TL;DR: This study provides a general paradigm relating oxygen status to ER function and growth factor signaling and shows that the microenvironmental stresses found in the solid tumor are able to inhibit the canonical Wnt/β-catenin signaling pathway.
Journal ArticleDOI
Cellular Reaction to Hypoxia: Sensing and Responding to an Adverse Environment
TL;DR: In this article, a series of coordinated responses in a time and oxygen concentration-dependent manner are designed to maintain cellular and tissue viability, and are comprised of transcriptional as well as post-transcriptional events.
