Abstract (sommario):

An inositol-requiring strain of Neurospora crassa was labelled during growth in liquid medium with [3H]inositol, and the levels of inositol phosphates and phosphoinositides were determined under inositol-sufficient and inositol-starved conditions. Because the mutant has an absolute requirement for inositol, the total mass of inositol-containing compounds could be determined. Inositol-containing lipids were identified by deacylation and co-migration with standards on h.p.l.c.; PtdIns3P, PtdIns4P, and PtdIns(4,5)P2 were found in approximately equal amounts, in addition to large amounts of PtdIns

Abstract (sommario):

Arthropod antimicrobial peptides (AMPs) offer a promising source of new leads to address the declining number of novel antibiotics and the increasing prevalence of multidrug-resistant bacterial pathogens. AMPs with potent activity against Gram-negative bacteria and distinct modes of action have been identified in insects and scorpions, allowing the discovery of AMP combinations with additive and/or synergistic effects. Here, we tested the synergistic activity of two AMPs, from the dung beetle Copris tripartitus (CopA3) and the scorpion Heterometrus petersii (Hp1090), against two strains of Esc

Abstract (sommario):

Offline Multi-Agent Reinforcement Learning (MARL) is an emerging field that aims to learn optimal multi-agent policies from pre-collected datasets. Compared to single-agent case, multi-agent setting involves a large joint state-action space and coupled behaviors of multiple agents, which bring extra complexity to offline policy optimization. In this work, we revisit the existing offline MARL methods and show that in certain scenarios they can be problematic, leading to uncoordinated behaviors and out-of-distribution (OOD) joint actions. To address these issues, we propose a new offline MARL al

Abstract (sommario):

The inositol (1,4,5)-trisphosphate receptor (InsP3R) mediates Ca2+ release from intracellular stores in response to generation of second messenger InsP3. InsP3R was biochemically purified and cloned, and functional properties of native InsP3-gated Ca2+ channels were extensively studied. However, further studies of InsP3R are obstructed by the lack of a convenient functional assay of expressed InsP3R activity. To establish a functional assay of recombinant InsP3R activity, transient heterologous expression of neuronal rat InsP3R cDNA (InsP3R-I, SI− SII+ splice variant) in HEK-293 cells was comb

Abstract (sommario):

Inositol 1,4,5-trisphosphate receptor type II (InsP3R-II) is the most prevalent isoform of the InsP3R in hepatocytes and is concentrated under the canalicular membrane, where it plays an important role in bile secretion. We hypothesized that altered calcium (Ca2+) signaling may be involved in metabolic dysfunction, as InsP3R-mediated Ca2+ signals have been implicated in the regulation of hepatic glucose homeostasis. Here, we find that InsP3R-II, but not InsP3R-I, is reduced in the livers of obese mice. In our investigation of the functional consequences of InsP3R-II deficiency, we found that o

Regulation of Ca2+release through inositol 1,4,5-trisphosphate receptors (InsP3R) has important consequences for defining the particular spatio-temporal properties of intracellular Ca2+signals. In this study, regulation of Ca2+release by phosphorylation of type 1 InsP3R (InsP3R-1) was investigated by constructing “phosphomimetic” charge mutations in the functionally important phosphorylation sites of both the S2+ and S2- InsP3R-1 splice variants.

Together with the number of channels activated and the open probability of the active channels, the size of the unitary Ca2+ current (iCa) passing through an open InsP3R channel determines the amount of Ca2+ released from the ER store, and thus the amplitude and the spatial and temporal nature of Ca2+

Abstract (sommario):

Inositol 1,4,5-trisphosphate (InsP3) is involved in the mobilization of Ca2+ from intracellular non-mitochondrial stores. In rat liver, it has been shown that the InsP3-binding site co-purifies with the plasma membrane. This suggests that in the liver the InsP3 receptor (InsP3R) associates with plasma membrane. We studied the subcellular distribution of the liver InsP3R by measuring the maximal binding capacity of [3H]InsP3 and using antibodies against the 14 C-terminal residues of the type 1 InsP3R. The antibodies recognized a large amount of an InsP3R protein of 260 kDa in a membrane fractio

Osteoblasts constitutively release glutamate and this release appears to be regulated by calcium entry. In this work we investigated if the bioactive glass with 60% of silicon (BG60S) could alter glutamate release by osteoblasts. We demonstrated that osteoblasts incubated with medium containing ionic products from the dissolution of BG60S showed lower release of glutamate when compared to control. Since intracellular calcium (Cai 2+) increase is required for glutamate release we investigated the subcellular distribution of the calcium channel inositol triphosphate receptors (InsP3Rs) in the pr

Abstract (sommario):

Calcium is a pleiotropic messenger controlling a diverse array of intracellular events from fertilization to cell death. One of the main mechanisms by which intracellular calcium is elevated is through InsP3 [Ins(1,4,5)P3]-induced mobilization of calcium from its receptor on the endoplasmic reticulum calcium store. The activity of the InsP3R (InsP3 receptor) is subject to regulation by many factors other than InsP3, most notably calcium itself, which regulates the channel in a bell-shaped dependent manner. InsP3R sensitivity is also regulated by post-translational modifications such as phospho

Abstract (sommario):

The InsP3R proteins have three recognized domains, the InsP3-binding, regulatory/coupling, and channel domains (Mignery, G.A., and T.C. Südhof. 1990. EMBO J. 9:3893–3898). The InsP3 binding domain and the channel-forming domain are at opposite ends of the protein. Ligand regulation of the channel must involve communication between these different regions of the protein. This communication likely involves the interceding sequence (i.e., the regulatory/coupling domain). The single channel functional attributes of the full-length recombinant type-1, -2, and -3 InsP3R channels have been defined.

Secretagogue-stimulated intracellular Ca2+ signals are fundamentally important for initiating the secretion of the fluid and ion component of saliva from parotid acinar cells. The Ca2+ signals have characteristic spatial and temporal characteristics, which are defined by the specific properties of Ca2+ release mediated by inositol 1,4,5-trisphosphate receptors (InsP3R). In this study we have investigated the role of adenine nucleotides in modulating Ca2+ release in mouse parotid acinar cells. In permeabilized cells, the Ca2+ release rate induced by submaximal [InsP3] was increased by 5 mM ATP.

However, regulation of InsP3R channel activity by free Ca2+ in the ER lumen ([Ca2+]ER) remains poorly understood because of limitations of Ca2+ flux measurements and imaging techniques. H

In this study, the functional consequences of phosphoregulation of InsP3Rs were investigated.
