M-Calpain Activation Facilitates Seizure Induced KCC2 Down Regulation
Frontiers in Molecular Neuroscience, 2018 Potassium chloride co-transporter 2 (KCC2), a major chloride transporter that maintains GABAA receptor inhibition in mature mammalian neurons, is down-regulated in the hippocampus during epileptogenesis.

μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]
, 2006 μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

Cancer Cell International, 2023 Background Glioblastoma multiforme (GBM) is characterized by an unfavorable prognosis for patients affected. During standard-of-care chemotherapy using temozolomide (TMZ), tumors acquire resistance thereby causing tumor recurrence.

Redox Biology, 2021 Mechanical ventilation (MV) is a life-saving intervention for many critically ill patients. Unfortunately, an unintended consequence of prolonged MV is the rapid development of diaphragmatic atrophy and contractile dysfunction, known as ventilator ...

The calpastatin-derived calpain inhibitor CP1B reduces mRNA expression of matrix metalloproteinase-2 and-9 and invasion by leukemic THP-1 cells [PDF]
, 2003 The ubiquitous proteases μ- and m-calpain are Ca2+-dependent cysteine endopeptidases. Besides involvement in a variety of physio(patho)logical processes, recent studies suggest a pivotal role of calpains in differentiation of hematopoietic cells and ...

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 ...

Reduction of myocardial infarction by calpain inhibitors A-705239 and A-705253 in isolated perfused rabbit hearts [PDF]
, 2004 Two novel calpain inhibitors (A-705239 and A-705253) were studied in isolated perfused rabbit hearts subjected to 60-min occlusion of the ramus interventricularis of the left coronary artery (below the origin of the first diagonal branch), followed by ...

Calpain activates caspase‐3 during UV‐induced neuronal death but only calpain is necessary for death [PDF]
Journal of Neurochemistry, 2002 AbstractWhile caspases have been strongly implicated in delayed neuronal death in a variety of experimental paradigms, other proteases such as calpain can also contribute to neuronal death. To evaluate the relative roles of caspase and calpain, we used a model system wherein UV treatment induced moderate or severe delayed cortical neuronal death, as ...

Calpain-3 impairs cell proliferation and stimulates oxidative stress-mediated cell death in melanoma cells. [PDF]
PLoS ONE, 2015 Calpain-3 is an intracellular cysteine protease, belonging to Calpain superfamily and predominantly expressed in skeletal muscle. In human melanoma cell lines and biopsies, we previously identified two novel splicing variants (hMp78 and hMp84) of Calpain-
