When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

The Growth Supporting Role of ZDHHC11 Is Linked to the MEF2B–BCL6 Regulatory Circuit in Burkitt Lymphoma

International Journal of Cancer, Volume 159, Issue 6, Page 1535-1545, 15 September 2026.
MEF2B and BCL6 have established functions in germinal center B‐cell biology and lymphomagenesis. The mechanism of MEF2B deregulation and its significance for cell survival in Burkitt lymphoma however remain unclear. This study highlights MEF2B as a crucial transcription factor in Burkitt lymphoma and suggests ZDHHC11 as an upstream regulator of MEF2B ...

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

Traffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

Unveiling New Insights: Reinterpreting DES Mutation, p.Arg383His, Through a Study of an Iranian Family With Isolated Hypertrophic Cardiomyopathy, Implication for Phenotype–Genotype Correlation Analysis

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Desmin, a crucial intermediate filament in muscle cells, maintains structural integrity in cardiac muscle and provides stability to striated muscle cells. Mutations in the DES gene lead to desminopathies, causing diverse cardiac and skeletal myopathies.

Safety, Tolerability, Pharmacokinetics, Food Effect of Ribitol, and Its Effect on QTcF in Healthy Adults: First‐in‐Human, Randomized, Double‐Blind (Sponsor Unblinded), Placebo‐Controlled Studies

Clinical Pharmacology in Drug Development, Volume 15, Issue 8, August 2026.
Abstract Limb‐girdle muscle dystrophy Type R9 (LGMDR9), also known as LGMD Type 2I, is a rare genetic disease caused by partial loss of function of fukutin‐related protein (FKRP) enzyme which glycosylates alpha‐dystroglycan, thereby stabilizing myocytes during contraction.
