HIF-1a

[Stem Cell Research & Therapy] Scientists performed an in-depth evaluation of the primitiveness, migration, adhesion, maturation, mitochondrial behavior, and pathway mechanisms of this platform using conventional assays followed by the evaluation of engraftment potential of the expanded CD34+ cells in an in vivo murine model.

[International Journal of Molecular Sciences] Myeloid hypoxia inducible factors(HIF)-1α and HIF-2α played opposing roles in acute dextran sodium sulfate colitis. Thus, not only a cell type specific, but also the isoform specific modulation of HIFs needs to be addressed in attempts to modify HIF for therapeutic purposes.

[Proceedings of the National Academy of Sciences of the United States of America] Investigators found that human and mouse macrophages underwent a switch to glycolysis in response to IgG immune complex stimulation, mirroring macrophage metabolic changes in inflamed tissue in vivo. This metabolic reprogramming was required to generate a number of proinflammatory mediators, including IL-1β, and was dependent on mTOR and hypoxia-inducible factor-1α.
