Calpain-1 knockout reveals broad effects on erythrocyte deformability and physiology [PDF]

open access: yesBiochemical Journal, 2012
Pharmacological inhibitors of cysteine proteases have provided useful insights into the regulation of calpain activity in erythrocytes. However, the precise biological function of calpain activity in erythrocytes remains poorly understood. Erythrocytes express calpain-1, an isoform regulated by calpastatin, the endogenous inhibitor of calpains.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Elevated calpain protein in AngII infused calpain-1 +/+ and calpain-1 −/− aortas.

open access: yes, 2013
Calpain-1 (A) and calpain-2 (B) proteins were detected by Western blotting in tissue extracts from aortas in calpain-1 +/+ x LDL receptor −/− and calpain-1 −/− x −/− LDL receptor −/− mice infused with either saline or AngII for 7 days.

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

open access: yesNeurobiology 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 ...

The expression of calpain 1 and calpain 2 in spermatogenic cells and spermatozoa of the mouse [PDF]

open access: yesReproduction, 2005
Abstract There is some evidence suggesting that Ca2+ is involved in processes that occur during the development and function of spermatozoa. Calcium-dependent proteins, such as calmodulin, are expressed during mammalian spermatogenesis further suggesting that Ca2+ takes part in its regulation.

Autophagy Plays a Suppressive Role in Bladder Tumor Formation in an Orthotopic Mouse Model and Bladder Cancer Patient Specimens

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Autophagy plays either a suppressing or promoting role during tumor development. Clarifying the role of autophagy in bladder tumorigenesis both in vitro and in vivo is crucial for developing novel therapeutic strategies through manipulating autophagy activity.

A Novel CAPN1 Mutation Causes a Pure Hereditary Spastic Paraplegia in an Italian Family

open access: yesFrontiers in Neurology, 2019
CAPN1 encodes calpain-1, a large subunit of μ-calpain, a calcium-activated cysteine protease widely present in the central nervous system. Mutations in CAPN1 have recently been identified in a complicated form of Hereditary Spastic Paraplegia (HSP) with ...

Proteomic Profiling of Myofiber Repair Annexins and Their Role in Duchenne Muscular Dystrophy

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Myofiber regeneration and membrane repair play crucial roles in maintaining the continuous physiological functioning of the neuromuscular system. A swift and efficient repair mechanism enables the rapid restoration of sarcolemmal integrity following cellular impairment in damaged skeletal muscles.

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

open access: yesPharmacological 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 ...

Broadening the View: Substance P and Its Metabolism in Pruritus‐Related Diseases

open access: yesThe Journal of Dermatology, EarlyView.
ABSTRACT Chronic pruritus is a debilitating symptom accompanying numerous inflammatory skin diseases and remains a major therapeutic challenge. Neurogenic inflammation plays a central role in its pathogenesis, with the tachykinin substance P acting as a key mediator at the interface of the nervous system, immune cells, and cutaneous tissues.
