Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

ESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Anterior cingulate cortex neuron subtypes differentially regulate seizures

Epilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.

Quantitative and amino acid sequence analysis of soluble HIV-1 Vpu and calmodulin interactions. [PDF]

Protein Sci
Abstract HIV‐1 Vpu supports viral adaptation through host‐protein interactions. Although mainly membrane‐associated, we recently identified a soluble Vpu form that forms a stable complex with Ca2+‐bound calmodulin (Ca2+–CaM), potentially influencing Vpu trafficking. Here, to determine the binding affinity and identify regions of soluble Vpu involved in

Epilepsy‐associated SCN2A‐L1342P mutation drives network hyperexcitability and widespread transcriptomic changes in human cortical organoids

Epilepsia, EarlyView.
Abstract Objective SCN2A pathogenic mutations, such as the recurrent heterozygous Nav1.2‐L1342P, are monogenic causes of epilepsy. In this human‐induced pluripotent stem cell–derived model system, we aim to investigate the molecular and cellular mechanisms underlying SCN2A‐L1342P‐associated pathology. Methods Using a human male induced pluripotent stem

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

Epilepsia, EarlyView.
Abstract Objective The voltage‐gated sodium channel Nav1.1, encoded by Scn1a, is essential for γ‐aminobutyric acid (GABA)ergic function, and its alteration is associated with neurological disorders such as Dravet syndrome and Alzheimer's disease. We previously demonstrated that local Nav1.1 dysfunction in the medial prefrontal cortex (mPFC) during ...

Untethered Electrical Stimulation Using Optoelectricity and Piezoelectricity for Tissue Regeneration

FlexTech, EarlyView.
Untethered electrical stimulation from optoelectronic and piezoelectric materials can aid regeneration of damaged tissue. ABSTRACT Electrical signals are increasingly recognized as important regulators of tissue development and regeneration, with outcomes linked to behaviors including proliferation, differentiation, cell migration, and more.

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)
