ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...

Novel Na<sub>V</sub>1.6-Mitochondrial Complexes in Retinal Astrocyte Pockets Sequester GABA. [PDF]
NaV1.6 localizes in retinal astrocytes' high density pockets on the bilayer facing the ganglion cell layer. NaV colocalizes with large, anaplerotic mitochondria. These microdomains accumulate high levels of GABA. ABSTRACT Voltage‐gated sodium channels are best known for their capacity to generate and propagate electrical currents in neurons and muscle.

ABSTRACT The Nav1.5 channel, a major isoform of voltage‐gated sodium ion channel, is mainly found in ventricular cardiomyocytes, playing a key role in generating essential cardiac action potentials for normal heart rhythms. Mutations in Nav1.5 have been associated with severe heart conditions such as long QT syndrome, Brugada syndrome, cardiac ...

ABSTRACT A straightforward method for the determination of dynamic domains from pairs of conformations or general conformational ensembles of proteins is presented. The method applies metric multi‐dimensional scaling (MDS) to distance‐differences or root‐mean square‐fluctuations of inter‐atomic distances (RMSFIDs).

Schematic overview of the multi‐target and multi‐pathway mechanisms of PDBI in the prevention and management of hypertension. ABSTRACT Hypertension remains a major global risk factor for cardiovascular diseases, yet current treatments face challenges such as suboptimal blood pressure control and inadequate organ protection.

Apigenin Protects Hypertensive Intracerebral Hemorrhage by Regulating Trx1 Through Binding to PRDX2
ABSTRACT Intracerebral hemorrhage (ICH) remains the most severe stroke subtype with high mortality and disability rates. Although apigenin has shown cerebroprotective potential in preclinical studies, its mechanism of action, particularly in hypertensive ICH, remains poorly understood.

ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Calmodulin modulates prolactin secretion in vitro: studies with calmodulin containing liposomes
The control of prolactin secretion by Ca calmodulin and cyclic AMP was studied. Ca++ ionophore A23187 stimulated both cyclic AMP accumulation and prolactin release by primary culture of anterior pituitary cells in vitro.
