Animal cell cytokinesis: the role of dynamic changes in the plasma membrane proteome and lipidome [PDF]
, 2016 In animal cells, cytokinesis is characterised by the formation of the mitotic spindle that signals the assembly of an actomyosin ring between the spindle poles.

Phosphatidylinositol‐3‐phosphate in the regulation of autophagy membrane dynamics [PDF]
The FEBS Journal, 2017 Phosphatidylinositol‐3‐phosphate (PI3P) is a key player in membrane dynamics and trafficking regulation. Most PI3P is associated with endosomal membranes and with the autophagosome preassembly machinery, presumably at the endoplasmic reticulum. The enzyme responsible for most PI3P synthesis, VPS34 and proteins such as Beclin1 and ATG14L that regulate ...

Loss of Class III Phosphoinositide 3-Kinase Vps34 Results in Cone Degeneration
Biology, 2020 The major pathway for the production of the low-abundance membrane lipid phosphatidylinositol 3-phosphate (PI(3)P) synthesis is catalyzed by class III phosphoinositide 3-kinase (PI3K) Vps34.

Inositols in Insulin Signaling and Glucose Metabolism [PDF]
, 2018 In the past decades, both the importance of inositol for human health and the complex interaction between glucose and inositol have been the subject of increasing consideration. Glucose has been shown to interfere with cellular transmembrane transport of

How to Eat One’s Feelings: Autophagy and Phosphatidylinositol 3-Phosphate [PDF]
The Plant Cell, 2020 Moving around taught me two essential skills, only one being relevant here: how to put up wallpaper, and how critical it is to label boxes to help the moving company drop them at their intended location.

Localization of phosphatidylinositol 3-phosphate in yeast and mammalian cells [PDF]
The EMBO Journal, 2000 Phosphatidylinositol 3-kinase (PI3K) regulates several vital cellular processes, including signal transduction and membrane trafficking. In order to study the intracellular localization of the PI3K product, phosphatidylinositol 3-phosphate [PI(3)P], we constructed a probe consisting of two PI(3)P-binding FYVE domains.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Physico-chemical requirements and kinetics of membrane fusion of flavivirus-like particles. [PDF]
, 2015 Flaviviruses deliver their RNA genome into the host-cell cytoplasm by fusing their lipid envelope with a cellular membrane. Expression of the flavivirus pre-membrane and envelope glycoprotein genes in the absence of other viral genes results in the ...

Metabolic Modulation Predicts Heart Failure Tests Performance [PDF]
, 2019 The metabolic changes that accompany changes in Cardiopulmonary testing (CPET) and heart failure biomarkers (HFbio) are not well known. We undertook metabolomic and lipidomic phenotyping of a cohort of heart failure (HF) patients and utilized Multiple ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
