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

Coupling biochemistry and mechanics in cell adhesion: a model for inhomogeneous stress fiber contraction

, 2007
Biochemistry and mechanics are closely coupled in cell adhesion. At sites of cell-matrix adhesion, mechanical force triggers signaling through the Rho-pathway, which leads to structural reinforcement and increased contractility in the actin cytoskeleton.

MiR‐375 in CAFs‐Derived EVs Promotes HCC Progression via Regulating RASA1 and May Potentially Serve as a Biomarker for HCC

Cancer Science, EarlyView.
CAFs could transfer EVs miR‐375 into endothelial cells with a low level of RASA1 and further promote EC angiogenesis. Plasma EVs miR‐375 have the potential values as a novel diagnostic and prognostic biomarker for HCC. ABSTRACT Cancer‐associated fibroblasts (CAFs) in the tumor microenvironment play an important role in cancer initiation and progression

Role of Phospholipase D in G-Protein Coupled Receptor Function

Membranes, 2014
Prolonged agonist exposure of many G-protein coupled receptors induces a rapid receptor phosphorylation and uncoupling from G-proteins. Resensitization of these desensitized receptors requires endocytosis and subsequent dephosphorylation.

Direct genetic demonstration of Gα13 coupling to the orphan G protein-coupled receptor G2A leading to RhoA-dependent actin rearrangement [PDF]

, 2000
G2A is an orphan G protein-coupled receptor (GPCR), expressed predominantly in T and B cells and homologous to a small group of GPCRs of unknown function expressed in lymphoid tissues.

Efficient Finite Difference Method for Computing Sensitivities of Biochemical Reactions

, 2018
Sensitivity analysis of biochemical reactions aims at quantifying the dependence of the reaction dynamics on the reaction rates. The computation of the parameter sensitivities, however, poses many computational challenges when taking stochastic noise ...

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

British Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.
