Non‐canonical PKG1 regulation in cardiovascular health and disease
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.

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

Synthesis of inositol phosphate-based competitive antagonists of inositol 1,4,5-trisphosphate receptors. [PDF]
Inositol 1,4,5-trisphosphate receptors (IP3Rs) are intracellular Ca(2+) channels that are widely expressed in animal cells, where they mediate the release of Ca(2+) from intracellular stores evoked by extracellular stimuli.

Modulation of flight and feeding behaviours requires presynaptic IP3Rs in dopaminergic neurons
Innate behaviours, although robust and hard wired, rely on modulation of neuronal circuits, for eliciting an appropriate response according to internal states and external cues.

Serotonergic signals enhanced hamster sperm hyperactivation
In the present study, we investigated the regulatory mechanisms underlying sperm hyperactivation enhanced by 5-hydroxytryptamine (5-HT) in hamsters. First, we examined the types of 5-HT receptors that regulate hyperactivation.

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

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

Mechanisms altering airway smooth muscle cell Ca(2+) homeostasis in two asthma models [PDF]
Background: Asthma is characterized by airway remodeling, altered mucus production and airway smooth muscle cell (ASMC) contraction causing extensive airway narrowing. In particular, alterations of ASMC contractility seem to be of crucial importance. The

Voltage-dependent anion channels: different isoforms for different functions [PDF]
The Voltage-dependent anion channel (VDAC) is the most abundant protein of the outer mitochondrial membrane (OMM) and mediates the flow of ions and metabolites between the cytoplasm and the mitochondrial network.

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 ...
