Recent advances in our understanding of the structure and function of more unusual cation channels. [PDF]

open access: yes, 2019
As their name implies, cation channels allow the regulated flow of cations such as sodium, potassium, calcium, and magnesium across cellular and intracellular membranes.

Increased susceptibility of striatal mitochondria to calcium-induced permeability transition [PDF]

open access: yes, 2003
Mitochondria were simultaneously isolated from striatum and cortex of adult rats and compared in functional assays for their sensitivity to calcium activation of the permeability transition.

Mitochondrial potassium channels: New properties and functions

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics
Mitochondria are recently implicated in phenomena such as cytoprotection, cellular senescence, tumor metabolism, and inflammation. The basis of these processes relies on biochemical functions of mitochondria such as the synthesis of reactive oxygen species or biophysical properties such as the integrity of the inner mitochondrial membrane.

Molecular Bases of Brain Preconditioning

open access: yesFrontiers in Neuroscience, 2017
Preconditioning of the brain induces tolerance to the damaging effects of ischemia and prevents cell death in ischemic penumbra. The development of this phenomenon is mediated by mitochondrial adenosine triphosphate-sensitive potassium (KATP+) channels ...

Role of mitochondrial potassium channels in ageing

open access: yesMitochondrion
Ageing is described as an inevitable decline in body functions over time and an increase in susceptibility to age-related diseases. Therefore, the increase of life expectancy is also viewed as a condition in which many elderly will develop age-related diseases and disabilities, such as cardiovascular, metabolic, neurological and oncological ones ...

Molecular Mechanisms in Exercise-Induced Cardioprotection

open access: yesCardiology Research and Practice, 2011
Physical inactivity is increasingly recognized as modifiable behavioral risk factor for cardiovascular diseases. A partial list of proposed mechanisms for exercise-induced cardioprotection include induction of heat shock proteins, increase in cardiac ...

Mitokondriális eredetű nitrogén szabadgyökök és ATP-függő K-csatornák szerepe az organellum működésében = The involvement of mitochondrial-derived nitrogen radicals and mitoK-ATP channels in the regulation of organelle function [PDF]

open access: yes, 2009
Elsőként a mitoKATP csatornák alegységeit terveztük azonosítani humán szív mintákon. A kísérletek során megbizonyosodtunk afelől, hogy a korábban ilyen csatornáknak gondolt fehérjék nincsenek jelen megfelelő számban és formában a mitokondriális ...

Why do axons differ in caliber? [PDF]

open access: yes, 2012
CNS axons differ in diameter (d) by nearly 100-fold (∼0.1-10 μm); therefore, they differ in cross-sectional area (d(2)) and volume by nearly 10,000-fold.

Mitochondrial preconditioning: a potential neuroprotective strategy

open access: yesFrontiers in Aging Neuroscience, 2010
Mitochondria have long been known as the powerhouse of the cell. However, these organelles are also pivotal players in neuronal cell death. Mitochondrial dysfunction is a prominent feature of chronic brain disorders, including Alzheimer's and ...

Mechanisms of sensorineural cell damage, death and survival in the cochlea. [PDF]

open access: yes, 2015
The majority of acquired hearing loss, including presbycusis, is caused by irreversible damage to the sensorineural tissues of the cochlea. This article reviews the intracellular mechanisms that contribute to sensorineural damage in the cochlea, as well ...
