Cell Rep 2021 May;35(6):109121

Institut NeuroMyoGène (INMG), Synaptopathies and Autoantibodies, Institut National de la Santé et de la Recherche Médicale (INSERM), U1217, Centre National de la Recherche Scientifique (CNRS) UMR5310, 69000 Lyon, France; Université Claude Bernard Lyon 1, 69000 Lyon, France. Electronic address:

The vascular endothelial growth factor (VEGF) pathway regulates key processes in synapse function, which are disrupted in early stages of Alzheimer's disease (AD) by toxic-soluble amyloid-beta oligomers (Aβo). Here, we show that VEGF accumulates in and around Aβ plaques in postmortem brains of patients with AD and in APP/PS1 mice, an AD mouse model. We uncover specific binding domains involved in direct interaction between Aβo and VEGF and reveal that this interaction jeopardizes VEGFR2 activation in neurons. Read More

Exercise-induced changes in miRNA expression in coronary artery disease.

Clin Chem Lab Med 2021 May 11. Epub 2021 May 11.

University Institute of Sports Medicine, Prevention and Rehabilitation and Research Institute of Molecular Sports Medicine and Rehabilitation, Paracelsus Medical University, Salzburg, Austria.

Objectives: Micro ribonucleic acids (miRNAs) are small non-coding RNA molecules that control gene expression by translational inhibition. Exercise has been shown to affect several miRNAs' expression in healthy subjects, but this has not yet been studied in patients with coronary artery disease (CAD). Since exercise training confers beneficial long-term effects and may also trigger acute coronary events, it is of utmost interest to be able to identify those who are risk for untoward effects.

Uncovering the signaling, structure and function of the 20-HETE-GPR75 pairing: Identifying CCL5 as a negative regulator of GPR75.

Br J Pharmacol 2021 May 11. Epub 2021 May 11.

Department of Pharmacology, New York Medical College School of Medicine, Valhalla, NY, 10595.

Background And Purpose: The G-protein coupled receptor GPR75 (Gq) and its ligand, the cytochrome P450-derived vasoactive eicosanoid 20-hydroxyeicosatetraenoic acid (20-HETE), are implicated in the activation of pro-inflammatory and hypertensive signaling cascades contributing to diabetes, obesity, vascular dysfunction/remodeling, hypertension and cardiovascular disease. Little is known as to how, where and with what affinity 20-HETE interacts with GPR75.

Experimental Approach: To better understand the pairing of 20-HETE and its receptor (GPR75), we employed the use of surface plasmon resonance (SPR) to determine binding affinity/kinetics. Read More

Wnt Signaling Cascades and Their Role in Coronary Artery Health and Disease.

J Cell Signal 2021 ;2(1):52-62

Section of Cardiovascular Medicine, Department of Internal Medicine, Yale University School of Medicine, New Haven, CT 06510, USA.

The Wnt signaling is classified as two distinct pathways of canonical Wnt/β-catenin signaling, and the non-canonical pathways of planar cell polarity and Wnt/Ca pathways. However, the scientific discoveries in recent years have shown that canonical and non-canonical Wnts pathways are intertwined and have complex interaction with other major signaling pathways such as hedgehog, Hippo and TOR signaling.
