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 ...

The Mitochondrial Ca(2+) Uniporter: Structure, Function, and Pharmacology. [PDF]

open access: yes, 2017
Mitochondrial Ca(2+) uptake is crucial for an array of cellular functions while an imbalance can elicit cell death. In this chapter, we briefly reviewed the various modes of mitochondrial Ca(2+) uptake and our current understanding of mitochondrial Ca(2+)

Mitochondria and the heart

open access: yesEuropean Heart Journal
Cardiac work demands a substantial amount of energy, stored in adenosine triphosphate (ATP), necessary for both contraction and relaxation. To meet these energy requirements, the heart is equipped with an efficient metabolic machinery. Mitochondria, the central organelle in maintaining cardiac function, primarily generate ATP through oxidative ...

Bimetallic Nanoreactor Activates cGAS‐STING Pathway via mtDNA Release for Cancer Metalloimmunotherapy

open access: yesAdvanced Functional Materials, EarlyView.
A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Extra-matrix Mg\u3csup\u3e2+\u3c/sup\u3e Limits Ca\u3csup\u3e2+\u3c/sup\u3e Uptake and Modulates Ca\u3csup\u3e2+\u3c/sup\u3e Uptake-independent Respiration and Redox State in Cardiac Isolated Mitochondria [PDF]

open access: yes, 2013
Cardiac mitochondrial matrix (m) free Ca2+ ([Ca2+]m) increases primarily by Ca2+ uptake through the Ca2+ uniporter (CU). Ca2+ uptake via the CU is attenuated by extra-matrix (e) Mg2+ ([Mg2+]e).

Visualizing mitochondrial FoF1-ATP synthase as the target of the immunomodulatory drug Bz-423

open access: yes, 2018
Targeting the mitochondrial enzyme FoF1-ATP synthase and modulating its catalytic activities with small molecules is a promising new approach for treatment of autoimmune diseases. The immuno-modulatory compound Bz-423 is such a drug that binds to subunit

Nanodiamond‐Based Quantum Sensing Reveals Changes in Endo‐Lysosomal Activity of Stimulated Cardiac Fibroblasts in a Cellular Fibrosis Model

open access: yesAdvanced Functional Materials, EarlyView.
Quantum sensing reveals intricate patterns linking endo‐lysosomal maturation to cardiac fibrosis progression, highlighting complexity in cellular remodeling. This study investigates fibroblast‐to‐myofibroblast transition under cell aging, stiffness, and TGF‐β stimulation, comparing nanodiamond uptake, endo‐lysosomal dynamics, and free radical ...

What is the function of mitochondrial networks? A theoretical assessment of hypotheses and proposal for future research [PDF]

open access: yes, 2015
Mitochondria can change their shape from discrete isolated organelles to a large continuous reticulum. The cellular advantages underlying these fused networks are still incompletely understood.

Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

open access: yesAdvanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...
