Glycolysis fuels phosphoinositide 3-kinase signaling to bolster T cell immunity

Science, 2020
A metabolic circuit in T cell immunity Naïve T cells are metabolically reprogrammed when they differentiate into T effector (Teff) cells, transitioning from a reliance on mitochondrial oxidative phosphorylation to aerobic glycolysis. Xu et al. found that

Phosphoinositide 3-kinase p85beta regulates invadopodium formation

Biology Open, 2014
The acquisition of invasiveness is characteristic of tumor progression. Numerous genetic changes are associated with metastasis, but the mechanism by which a cell becomes invasive remains unclear.

Membrane and Protein Interactions of the Pleckstrin Homology Domain Superfamily. [PDF]

, 2015
The human genome encodes about 285 proteins that contain at least one annotated pleckstrin homology (PH) domain. As the first phosphoinositide binding module domain to be discovered, the PH domain recruits diverse protein architectures to cellular ...

SHIP2 inhibition alters redox‐induced PI3K/AKT and MAP kinase pathways via PTEN over‐activation in cervical cancer cells

FEBS Open Bio, 2020
Phosphatidylinositol (3,4,5)‐trisphosphate (PI(3,4,5)P3) is required for protein kinase B (AKT) activation. The level of PI(3,4,5)P3 is constantly regulated through balanced synthesis by phosphoinositide 3‐kinase (PI3K) and degradation by ...

Targeting PI3Kδ and PI3Kγ signalling disrupts human AML survival and bone marrow stromal cell mediated protection [PDF]

, 2016
Phosphoinositide-3-kinase (PI3K) is an enzyme group, known to regulate key survival pathways in acute myeloid leukaemia (AML). It generates phosphatidylinositol-3,4,5-triphosphate, which provides a membrane docking site for protein kinaseB activation ...
