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.

Accurate Generation of Conformational Ensembles for Intrinsically Disordered Proteins with IDPFold

Advanced Science, Volume 12, Issue 48, December 29, 2025.
In brief: IDPFold predicts the conformational ensembles of intrinsically disordered proteins (IDPs) from their amino acid sequences. The atomic structures generated by IDPFold offer crucial insights into the intricate relationship between IDP structures and their diverse biological functions.2 Abstract Intrinsically disordered proteins (IDPs) play ...

Peeling Skin, Leukonychia, Acral Punctate Keratoses, Cheilitis and Knuckle Pads (PLACK) Syndrome: An Updated Review of Cases and Identification of a Recurrent CAST Variant in Two Patients

Pediatric Dermatology, Volume 42, Issue 6, Page 1239-1247, November/December 2025.
ABSTRACT Peeling skin, leukonychia, acral punctate keratoses, cheilitis, and knuckle pads (PLACK) syndrome (OMIM616295) is an exceptionally rare autosomal recessive genodermatosis caused by loss‐of‐function pathogenic variants in the CAST gene, encoding calpastatin.

Ex vivo measurement of calpain activation in human peripheral blood lymphocytes by detection of immunoreactive products of calpastatin degradation.

Folia Histochemica et Cytobiologica, 2008
Limited proteolysis of multiple intracellular proteins by endogenous Ca-dependent cysteine proteases--calpains--is an important regulatory mechanism for cell proliferation, apoptosis etc.

Adipocyte Calpain‐2 Deficiency Reduces Obesity‐Accelerated Abdominal Aortic Aneurysm Formation in Mice

FASEB BioAdvances, Volume 7, Issue 10, October 2025.
Adipocyte‐specific deletion of calpain‐2 in mice decreases obesity‐accelerated abdominal aortic aneurysm formation, which is associated with reduced aortic medial elastin fragmentation and periaortic adipose tissue leukocyte accumulation. Targeted inhibition of calpain‐2 may offer a new therapeutic target to reduce obesity‐accelerated abdominal aortic ...

Effect of Ca2+ on binding of the calpains to calpastatin

Journal of Biological Chemistry, 1989
Autolyzed mu-calpain, unautolyzed mu-calpain, autolyzed m-calpain, and unautolyzed m-calpain (mu-calpain is the micromolar Ca2+-requiring proteinase, m-calpain is the millimolar Ca2+-requiring proteinase) were passed through a calpastatin-affinity column at different free Ca2+ concentrations, and binding of the calpains to calpastatin was compared with

Dry‐Aged Beef: A Global Review of Meat Quality Traits, Microbiome Dynamics, Safety, and Sustainable Strategies

Journal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT Dry‐aged beef is valued for its tenderness, complex aroma, and concentrated flavor. However, variability in aging protocols and limited understanding of underlying biological and technological processes can compromise consistent quality and safety.

Determination of skeletal muscle calpain and calpastatin activities during maturation

, 1991
Our objectives were to characterize events underlying changes in skeletal muscle calpain and calpastatin activities, using maturation as a model. Muscle samples were taken from rabbits of four ages (newborn and 1, 2, and 5 mo old).
