Purification of Advanced Therapeutics by Flow‐Through Pseudo‐Affinity Chromatography: Bi‐Specific mABs, Fc Fusion Proteins, and Adeno‐Associated Viruses

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Modern biopharmaceutical manufacturing requires purification platforms capable of processing structurally and functionally diverse products while addressing the challenge of removing persistent and high‐risk host cell proteins (HCPs).

Hippocampal calpain is required for the consolidation and reconsolidation but not extinction of contextual fear memory

Molecular Brain, 2017
Memory consolidation, reconsolidation, and extinction have been shown to share similar molecular signatures, including new gene expression. Calpain is a Ca2+-dependent protease that exerts its effects through the proteolytic cleavage of target proteins ...

Viscoelastic hydrogel potentiates cancer cell stemness and drug resistance through Piezo1‐dependent mechanotransduction

BMEMat, EarlyView.
The effects of matrix dynamics on cancer progression remain unclear. Herein, we fabricated a tunable dynamic hydrogel via reversible host–guest crosslinking and demonstrated that high matrix dynamics activate Piezo1 and its downstream PI3K/AKT and Wnt/β‐catenin signaling pathways, thereby enhancing cancer spheroid assembly, elevating cancer stemness ...

Assembly and Maintenance of Myofibrils in the Heart

Cytoskeleton, EarlyView.
ABSTRACT The assembly of actin and myosin to the paracrystalline arrangement of myofibrils in striated muscle, that is, heart and skeletal, has puzzled many a cell biologist. Different models, based on cultured cardiomyocytes, were proposed for the last 30 years to explain the sequence of events.

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

Cytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Calpain-mediated degradation of GFAP at 2 h following blast injury.

, 2017
Proteins were isolated from sham control (Sham), low-blast (L-Blast), and high-blast (H-Blast) OHCs at 2 h post-injury and analyzed via western blot for expression of GFAP (A, B) or calpain (C).

Calpain cleavage of Junctophilin-2 generates a spectrum of calcium-dependent cleavage products and DNA-rich NT1-fragment domains in cardiomyocytes

Scientific Reports, 2022
Calpains are calcium-activated neutral proteases involved in the regulation of key signaling pathways. Junctophilin-2 (JP2) is a Calpain-specific proteolytic target and essential structural protein inside Ca2+ release units required for excitation ...

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

ESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

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 ...

Cysteine Peptidases in Antitumor Immunity: Unraveling Antigen‐Presenting Cell Regulation and Therapeutic Potential

iMetaMed, EarlyView.
This review systematically summarizes the central role of cysteine peptidases in modulating antigen‐presenting cell (APC) function and antitumor immune responses, highlighting their critical significance in overcoming tumor immune evasion. Current research has established that cysteine peptidase subtypes, including cathepsins B, S, L, and X, exert ...
