Studies of protein post-translational modifications using high resolution tandem mass spectrometry [PDF]

Electron capture dissociation (ECD) is a powerful and superior tandem mass spectrometry (MS) fragmentation technique in the study of protein post-translational modifications (PTMs) due to its unique features of preserving labile modifications and ...

Dopamine: The Essential Bridge Mediating Obstructive Sleep Apnea and Hippocampus‐Dependent Learning and Memory Impairments

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Obstructive sleep apnea is a clinical syndrome that triggers a series of pathophysiologic changes, including disturbed sleep architecture, chronic intermittent hypoxia and hypercapnia, and ultimately severe cognitive dysfunction. The hippocampus plays a key role in various cognitive processes such as learning and memory.

In vitro starch binding experiments: Study of the proteins related to grain hardness of wheat [PDF]

, 2007
Two friabilin components, puroindoline a and GSP-1 were expressed in Escherichia coli. Starch binding properties of the recombinant polypeptides and of friabilin extracted from wheat flour were compared in vitro. The produced proteins as well as native

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Intracellular Calcium-Binding Proteins in Signal Transduction

CHIMIA, 1992
Cell stimulation generates a Ca2+ signal, which is perceived by intracellular Ca2+-binding proteins. These proteins are made up of different units of a conserved structural motif, called the 2S domain, and composed mainly of four ?-helices and ...

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.

A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

British Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.

Integrated protein array screening and high throughput validation of 70 novel neural calmodulin binding proteins

, 2010
Calmodulin is an essential regulator of intracellular processes in response to extracellular stimuli mediated by a rise in Ca(2+) ion concentration. To profile protein-protein interactions of calmodulin in human brain, we probed a high content human ...

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

Atrial natriuretic peptide counteracts aldosterone secretion by preventing acute angiotensin II‐induced cAMP signalling

British Journal of Pharmacology, EarlyView.
Background and Purpose Aldosterone plays a key role in blood pressure and volume regulation. Enhanced aldosterone secretion contributes to cardiovascular and renal diseases. Therefore, inhibitors of aldosterone receptors and synthase are essential drugs for the treatment of hypertension and heart failure.
