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

eLife, 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).

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Intracellular calcium channels: Inositol-1,4,5-trisphosphate receptors [PDF]

European Journal of Pharmacology, 2014
The inositol-1,4,5-trisphosphate receptors (InsP3Rs) are the major intracellular Ca(2+)-release channels in cells. Activity of InsP3Rs is essential for elementary and global Ca(2+) events in the cell. There are three InsP3Rs isoforms that are present in mammalian cells. In this review we will focus primarily on InsP3R type 1.

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Akt Kinase Phosphorylation of Inositol 1,4,5-Trisphosphate Receptors [PDF]

Journal of Biological Chemistry, 2006
A consensus RXRXX(S/T) substrate motif for Akt kinase is conserved in the C-terminal tail of all three inositol 1,4,5-trisphosphate (IP3) receptor (IP3R) isoforms. We have shown that IP3R can be phosphorylated by Akt kinase in vitro and in vivo. Endogenous IP3Rs in Chinese hamster ovary T-cells were phosphorylated in response to Akt activation by ...

Inositol 1,4,5-trisphosphate receptor binding: autoradiographic localization in rat brain

, 1989
Inositol 1,4,5-trisphosphate is a second messenger generated by stimulation of the phosphoinositide cycle, thought to release calcium from intracellular stores. We have mapped the distribution of 3H- inositol 1,4,5-trisphosphate receptor binding sites in

Impact of incretin analogues on lipid and lipoprotein metabolism in obesity and diabetes

British Journal of Pharmacology, EarlyView.
Abstract Incretin‐based therapies have gained momentum as a key strategy for reducing cardiovascular risk in individuals with obesity and/or type 2 diabetes (T2D). It remains unclear whether the cardiovascular benefits reflect a direct reduction in atherogenic lipoproteins—namely, low‐density lipoproteins (LDL), very low‐density lipoproteins (VLDL) and

Enriched endoplasmic reticulum-mitochondria interactions result in mitochondrial dysfunction and apoptosis in oocytes from obese mice

Journal of Animal Science and Biotechnology, 2017
Background Maternal obesity alters oocytes and subsequent fetal metabolism. An increasing number of studies have shown that the endoplasmic reticulums (ER) or mitochondria have important effects on oocyte quality, but there has been no study of the ...

The nitty‐gritty of vascular permeability in cancer: targeting blood endothelium to control metastases

British Journal of Pharmacology, EarlyView.
Blood vascular permeability is a hallmark of cancer and acts as an active driver of metastatic dissemination. Metastasis accounts for the vast majority of cancer deaths, yet most work has focussed on tumour‐intrinsic traits and angiogenesis, while the specific contribution of endothelial barrier regulation to intravasation and extravasation remains ...
