Silencing of the Metabolic Gene HKDC1 Is Associated With Aging and Neurodegeneration in Mice and Humans

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
Model showing decline in HKDC1 gene expression with aging. In a young cell, TFEB gets recruited to its binding sites on the HKDC1 promoter to upregulate HKDC1 expression, which interacts with mitochondria and stabilizes PINK1 to maintain mitochondrial health.

Integrins engage mitochondrial function for signal transduction by a mechanism dependent on Rho GTPases. [PDF]

open access: yes, 2002
We show here the transient activation of the small GTPase Rac, followed by a rise in reactive oxygen species (ROS), as necessary early steps in a signal transduction cascade that lead to NFkappaB activation and collagenase-1 (CL-1)/matrix ...

Modulation of mitochondrial calcium as a pharmacological target for Alzheimer's disease [PDF]

open access: yes, 2010
Perturbed neuronal calcium homeostasis is a prominent feature in Alzheimer's disease (AD). Mitochondria accumulate calcium ions (Ca2+) for cellular bioenergetic metabolism and suppression of mitochondrial motility within the cell.

Glycative Stress Disrupts the Mitochondrial‐Lysosome Axis and Promotes Geroconversion in Aging Cardiomyocytes

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
Cardiac aging promotes mitochondrial AGE accumulation driven by defective glycative stress detoxification. AGE‐modified mitochondria disrupt lysosomal proteolysis, impairing mitophagy and promoting lipofuscin buildup. This mechanism sustains chronic unresolved mitochondrial damage, driving proinflammatory senescence in cardiomyocytes and defining a ...

Mitochondrial ion channels/transporters as sensors and regulators of cellular redox signaling. [PDF]

open access: yes, 2014
SIGNIFICANCE: Mitochondrial ion channels/transporters and the electron transport chain (ETC) serve as key sensors and regulators for cellular redox signaling, the production of reactive oxygen species (ROS) and nitrogen species (RNS) in mitochondria, and

Pioglitazone Ameliorates Mitochondrial Oxidative Stress and Inflammation via AMPK‐Dependent Inhibition of Mitochondrial Fission in Leigh Syndrome

open access: yesCell Proliferation, Volume 59, Issue 3, March 2026.
Pioglitazone suppresses mitochondrial excessive ROS generation and COX‐2 level through inhibition of Drp‐1 mediated mitochondrial fission in an AMPK‐dependent manner in LS. ABSTRACT Loss of function mutations of NDUFS4 resulted in Leigh syndrome, which is a progressive neurodegenerative disease and characterized by mitochondrial oxidative stress ...

HIV-1 promonocytic and lymphoid cell lines: an in vitro model of in vivo mitochondrial and apoptotic lesion. [PDF]

open access: yes, 2016
To characterize mitochondrial/apoptotic parameters in chronically human immunodeficiency virus (HIV-1)-infected promonocytic and lymphoid cells which could be further used as therapeutic targets to test pro-mitochondrial or anti-apoptotic strategies as ...

A Proteomic Study of Memory After Imprinting in the Domestic Chick. [PDF]

open access: yes, 2015
The intermediate and medial mesopallium (IMM) of the domestic chick forebrain has previously been shown to be a memory system for visual imprinting. Learning-related changes occur in certain plasma membrane and mitochondrial proteins in the IMM.

Tubulin-VDAC Interaction: Molecular Basis for Mitochondrial Dysfunction in Chemotherapy-Induced Peripheral Neuropathy

open access: yesFrontiers in Physiology, 2019
Tubulin is a well-established target of microtubule-targeting agents (MTAs), a widely used class of chemotherapeutic drugs. Yet, aside from their powerful anti-cancer efficiency, MTAs induce a dose-limiting and debilitating peripheral neurotoxicity ...

Role of cysteines in mammalian VDAC isoforms' function

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2016
In this mini-review, we analyze the influence of cysteines in the structure and activity of mitochondrial outer membrane mammalian VDAC isoforms. The three VDAC isoforms show conserved sequences, similar structures and the same gene organization. The meaning of three proteins encoded in different chromosomes must thus be searched for subtle differences
