Inositol 1,4,5-Trisphosphate Receptor Type 3 Regulates Neuronal Growth Cone Sensitivity to Guidance Signals

open access: yesiScience, 2020
Summary: During neurodevelopment, the growth cone deciphers directional information from extracellular guidance cues presented as shallow concentration gradients via signal amplification.

A basal level of γ-linolenic acid depletes Ca2+ stores and induces endoplasmic reticulum and oxidative stresses to cause death of breast cancer BT-474 cells

open access: yesChinese Journal of Physiology, 2021
Gamma-linolenic acid (GLA), a natural fatty acid obtained from oils of various vegetables and seeds, has been demonstrated as an anticancer agent. In this work, we investigated the anticancer effects of GLA on breast cancer BT-474 cells.

A mathematical model of calcium dynamics in HSY cells. [PDF]

open access: yesPLoS Computational Biology, 2017
Saliva is an essential part of activities such as speaking, masticating and swallowing. Enzymes in salivary fluid protect teeth and gums from infectious diseases, and also initiate the digestion process. Intracellular calcium (Ca2+) plays a critical role

IP3-Dependent Ca2+ Oscillations Switch into a Dual Oscillator Mechanism in the Presence of PLC-Linked Hormones

open access: yesiScience, 2020
Summary: Ca2+ oscillations that depend on inositol-1,4,5-trisphosphate (IP3) have been ascribed to biphasic Ca2+ regulation of the IP3 receptor (IP3R) or feedback mechanisms controlling IP3 levels in different cell types.

Decavanadate displaces inositol 1,4,5-trisphosphate (IP3) from its receptor and inhibits IP3 induced Ca2+ release in permeabilized pancreatic acinar cells [PDF]

open access: yes, 1991
Inositol 1,4,5-trisphosphate (IP3) induced Ca2+ release in digitonin permeabilized rat pancreatic acinar cells is specifically inhibited by decavanadate.

Hormone-Induced Calcium Oscillations Depend on Cross-Coupling with Inositol 1,4,5-Trisphosphate Oscillations

open access: yesCell Reports, 2014
Receptor-mediated oscillations in cytosolic Ca2+ concentration ([Ca2+]i) could originate either directly from an autonomous Ca2+ feedback oscillator at the inositol 1,4,5-trisphosphate (IP3) receptor or as a secondary consequence of IP3 oscillations ...

Regulation of store-operated Ca2+ entry by IP3 receptors independent of their ability to release Ca2+

open access: yeseLife, 2023
Loss of endoplasmic reticular (ER) Ca2+ activates store-operated Ca2+ entry (SOCE) by causing the ER localized Ca2+ sensor STIM to unfurl domains that activate Orai channels in the plasma membrane at membrane contact sites (MCS).

Dynamic regulation of IP3 receptor clustering and activity by IP3 [PDF]

open access: yesChannels, 2009
Inositol 1,4,5-trisphosphate receptors (IP(3)Rs) are intracellular Ca(2+) channels. Their regulation by both IP(3) and Ca(2+) allows interactions between IP(3)Rs to generate a hierarchy of intracellular Ca(2+) release events. These can progress from openings of single IP(3)R, through near-synchronous opening of a few IP(3)Rs within a cluster to much ...

Structural insights into the regulatory mechanism of IP3 receptor [PDF]

open access: yes, 2004
Inositol 1,4,5-trisphosphate receptors (IP3R) are intracellular Ca2+ release channels whose opening requires binding of two intracellular messengers IP3 and Ca2+.

Image1_CD73-Adenosine A1R Axis Regulates the Activation and Apoptosis of Hepatic Stellate Cells Through the PLC-IP3-Ca2+/DAG-PKC Signaling Pathway.TIFF

open access: yes, 2022
Alcohol-related liver fibrosis (ALF) is a form of alcohol-related liver disease (ALD) that generally occurs in response to heavy long-term drinking. Ecto-5′-nucleotidase (NT5E), also known as CD73, is a cytomembrane protein linked to the cell membrane ...
