Effect of calcium chloride injection and freezing prior to wet aging on the meat quality of cull cows

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3478-3486, April 2026.
Abstract BACKGROUND In Brazil, the slaughter of female cattle, particularly older animals, has increased substantially. However, meat from this category presents limitations in terms of quality, mainly because of its toughness resulting from a high concentration of cross‐links between collagen fibers.

Axon Initial Segment: Structure, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 4, April 2026.
The axon initial segment (AIS) is a specialized axonal domain critical for maintaining neuronal polarity, action potential initiation, and network stability. This review summarizes the necessary elements for maintaining AIS structure and plasticity, discussing crucial biological functions of AIS in neuronal signaling and the neural circuit homeostasis,

Dysfunctional mitochondria uphold calpain activation: Contribution to Parkinson's disease pathology

Neurobiology of Disease, 2010
Calpain is a ubiquitous calcium-sensitive protease that is essential for normal physiologic neuronal function. However, mitochondrial-mediated-calcium homeostasis alterations may lead to its pathologic activation that jeopardizes neuronal structure and ...

Toxic mechanisms of amyloid oligomers and therapeutic strategies

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...

Calpain 3 is important for muscle regeneration: Evidence from patients with limb girdle muscular dystrophies

BMC Musculoskeletal Disorders, 2012
Background Limb girdle muscular dystrophy (LGMD) type 2A is caused by mutations in the CAPN3 gene and complete lack of functional calpain 3 leads to the most severe muscle wasting.

Ninjurin1 in cardiovascular and vascular biology: From molecular mechanisms to therapeutic opportunities

Clinical and Translational Medicine, Volume 16, Issue 3, March 2026.
NINJ1 mediates PMR in cardiovascular cell death, releasing DAMPs that amplify vascular inflammation. Dual NINJ1 paradox: membrane‐bound form drives endothelial NF‐κB/CXCL‐8 inflammation while soluble form provides atheroprotection. Pericyte NINJ1 regulates the critical balance between angiogenic sprouting and vessel maturation in ischaemic tissues ...

Calpain-Calcineurin-Nuclear Factor Signaling and the Development of Atrial Fibrillation in Patients with Valvular Heart Disease and Diabetes

Journal of Diabetes Research, 2016
Calpain, calcineurin (CaN), and nuclear factor of activated T cell (NFAT) play a key role in the development of atrial fibrillation. Patients with valvular heart disease (VHD) are prone to develop atrial fibrillation (AF).

Implementing a Tiered Genetic Testing Strategy for Muscular Dystrophies in Morocco: From Targeted Assays to Exome Sequencing

Molecular Genetics &Genomic Medicine, Volume 14, Issue 3, March 2026.
Targeted routine testing combined with NGS approaches enabled effective genetic diagnosis of muscular dystrophies in Moroccan patients, with nearly half of cases resolved by first‐line testing and additional diagnoses obtained through targeted sequencing and whole‐exome sequencing.

Apoptosis and motor deficits in SPG76 hereditary spastic paraplegia: Calpain 2 inhibition as therapeutic strategy

Pharmacological Research
SPG76 is a complicated form of hereditary spastic paraplegia (HSP) associated with mutations in the CAPN1 gene. The encoded protein, calpain 1, is a calcium-activated cysteine protease that catalyzes the proteolytic cleavage of a variety of cellular ...

Disruption of the l‐DOPA Receptor Gpr143/OA1‐Gene in Mice Creates a Unique Mixed Psychosis‐Like Phenotype

Neuropsychopharmacology Reports, Volume 46, Issue 1, March 2026.
We analyzed the behavior of GPR143 gene‐deficient mice. GPR143‐KO mice displayed a mixed psychiatric phenotype. GPR143 may play a role in mesolimbic and mesocortical functions underlying sensory gating, reward, social hierarchy, cognition, and emotional regulation. ABSTRACT GPR143, originally identified as the gene product of ocular albinism 1 (OA1), a
