Gαq signalling from endosomes: A new conundrum
Abstract G‐protein‐coupled receptors (GPCRs) constitute the largest family of membrane receptors, and are involved in the transmission of a variety of extracellular stimuli such as hormones, neurotransmitters, light and odorants into intracellular responses.

Microtextures in the Chelyabinsk impact breccia reveal the history of Phosphorus-Olivine-Assemblages in chondrites [PDF]
The geochemistry and textural associations of chondritic phosphate minerals can provide insights into the geological histories of parental asteroids, but the processes governing their formation and deformation remain poorly constrained. Here, we present a quantitative assessment of phosphorus-bearing mineral textures in the three variously-shocked ...

Type II phosphoinositide 5-phosphatases have unique sensitivities towards fatty acid composition and head group phosphorylation [PDF]
The catalytic properties of the type II phosphoinositide 5-phosphatases of Lowe's oculocerebrorenal syndrome, INPP5B, Synaptojanin1, Synaptojanin2 and SKIP were analysed with respect to their substrate specificity and enzymological properties.

Cisplatin causes reactive oxygen species accumulation, leading to apoptosis and inflammation in cochlear hair cells. Small extracellular vesicles primarily derived from the damaged hair cells likely contribute to cisplatin‐induced ototoxicity, carrying a variety of microRNAs and proteins.

Regulation of Hematopoietic Cell Development and Function Through Phosphoinositides
One of the most paramount receptor-induced signal transduction mechanisms in hematopoietic cells is production of the lipid second messenger phosphatidylinositol(3,4,5)trisphosphate (PIP3) by class I phosphoinositide 3 kinases (PI3K).

Light Activation of the Phosphoinositide Cycle in Intrinsically Photosensitive Chicken Retinal Ganglion Cells [PDF]
Purpose: In vertebrates, intrinsically photosensitive retinal ganglion cells (ipRGCs) acting as nonvisual photoreceptors transmit environmental illumination information to the brain, regulating diverse non–image-forming tasks.

Evidence for a specific phosphatidylinositol 4-phosphate phosphatase in human erythrocyte membranes.
Human erythrocyte membranes exhibit a specific phosphatidylinositol 4-phosphate phosphohydrolase (PtdIns4P phosphatase) activity which hydrolyzes PtdIns4P and lysoPtdIns4P but not phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) or lysoPtdIns(4,5)P2.

Inducing ferroptosis is a promising strategy for combating tumor resistance. Upregulated PIP5K1A competes with NRF2 for KEAP1 binding, which decreases the ubiquitination degradation of NRF2 and promotes its nuclear translocation, thereby suppressing ferroptosis, and ultimately driving hepatocellular carcinoma (HCC) tumorigeneses and sorafenib ...

The analysis of tissue phospholipids: hydrolysis procedure and results with pig liver
A procedure for the hydrolysis of phospholipids is described. The effect of alkali concentration, organic solvents, and length of hydrolysis have been studied. The initial reaction in the preferred solvent system appears to be a methanolysis.
