Quercetin promotes gastrointestinal motility and mucin secretion in loperamide-induced constipation of SD rats through regulation of the mAChRs downstream signal

open access: yesPharmaceutical Biology, 2018
Context: Quercetin (QCT) has been known as a potential therapeutic strategy for gastrointestinal diseases because it contributes to the stabilization of mast cells, the prevention of histamine release and modulation of CaCC chloride channel.

Phospholipase C-β1 and β4 contribute to non-genetic cell-to-cell variability in histamine-induced calcium signals in HeLa cells. [PDF]

open access: yesPLoS ONE, 2014
A uniform extracellular stimulus triggers cell-specific patterns of Ca(2+) signals, even in genetically identical cell populations. However, the underlying mechanism that generates the cell-to-cell variability remains unknown.

IP3 receptors: Take four IP3 to open. [PDF]

open access: yes, 2016
Inositol 1,4,5-trisphosphate receptors (IP3Rs) and ryanodine receptors are the channels responsible for Ca(2+)release from the endoplasmic and sarcoplasmic reticulum.

Breast Cancer-Derived AZU1 Educates Neutrophils to Promote Tumor Progression and Metastasis Through PAD4-Dependent Extracellular Trap Formation. [PDF]

open access: yesMol Carcinog
ABSTRACT Neutrophil extracellular traps (NETs) play crucial roles in cancer progression, but their regulatory mechanisms in breast cancer remain poorly understood. We developed a NETs‐related prognostic risk model using TCGA breast cancer data and identified key biomarkers through bioinformatics analysis.

Dual-FRET imaging of IP3 and Ca2+ revealed Ca2+-induced IP3 production maintains long lasting Ca2+ oscillations in fertilized mouse eggs [PDF]

open access: yes, 2019
In most species, fertilization induces Ca(2+) transients in the egg. In mammals, the Ca(2+) rises are triggered by phospholipase Czeta (PLCzeta) released from the sperm; IP3 generated by PLCzeta induces Ca(2+) release from the intracellular Ca(2+) store ...

On the partition property of measures on Pℋλ

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
The partition property for measures on Pℋλ was formulated by analogy with a property which Rowbottom [1] proved was possessed by every normal measure on a measurable cardinal. This property has been studied in [2], [3], and [4].

ADP stimulates IP3 formation in human platelets [PDF]

open access: yes, 1986
Aspirinated human platelets labeled with 32PO4 showed a 1.7-fold increase in [32P]IP3 when stimulated with ADP. ADP-stimulated mobilization of internal Ca2+ and phosphorylation of myosin were enhanced in the presence of extracellular Ca2+ but the ...

Allosteric response to ligand binding: Molecular dynamics study of the N-terminal domains in IP3 receptor

open access: yesBiophysics and Physicobiology, 2019
Inositol 1,4,5-trisphosphate (IP3) receptor (IP3R) is a huge tetrameric intracellular Ca2+ channel that mediates cytoplasmic Ca2+ signaling. The structural basis of the gating in IP3R has been studied by X-ray crystallography and cryo-electron microscopy,

Quantifying the dose-dependent impact of intracellular amyloid beta in a mathematical model of calcium regulation in xenopus oocyte.

open access: yesPLoS ONE, 2021
Alzheimer's disease (AD) is a devastating illness affecting over 40 million people worldwide. Intraneuronal rise of amyloid beta in its oligomeric forms (iAβOs), has been linked to the pathogenesis of AD by disrupting cytosolic Ca2+ homeostasis. However,
