Does Disruption of Optic Atrophy-1 (OPA1) Contribute to Cell Death in HL-1 Cardiomyocytes Subjected to Lethal Ischemia-Reperfusion Injury?

open access: yesCells, 2022
Disruption of mitochondrial structure/function is well-recognized to be a determinant of cell death in cardiomyocytes subjected to lethal episodes of ischemia-reperfusion (IR). However, the precise mitochondrial event(s) that precipitate lethal IR injury

Real-time PCR based on SYBR-Green I fluorescence: An alternative to the TaqMan assay for a relative quantification of gene rearrangements, gene amplifications and micro gene deletions [PDF]

open access: yes, 2003
BACKGROUND: Real-time PCR is increasingly being adopted for RNA quantification and genetic analysis. At present the most popular real-time PCR assay is based on the hybridisation of a dual-labelled probe to the PCR product, and the development of a ...

Repeated Disuse Atrophy Imprints a Molecular Memory in Skeletal Muscle: Transcriptional Resilience in Young Adults and Susceptibility in Aged Muscle

open access: yesAdvanced Science, EarlyView.
Repeated disuse imprints a molecular memory in skeletal muscle, conferring transcriptional resilience in young adults but exaggerated susceptibility in aged muscle, driven by epigenetic regulation of aerobic metabolism, mitochondrial and NAD+ pathways.

Structural and evolutionary characteristics of dynamin-related GTPase OPA1 [PDF]

open access: yesPeerJ, 2019
OPA1 is a dynamin-related GTPase that controls mitochondrial fusion, cristae remodeling, energetics and mtDNA maintenance. However, the molecular architecture of OPA1 is poorly understood.

p32/OPA1 axis-mediated mitochondrial dynamics contributes to cisplatin resistance in non-small cell lung cancer

open access: yesActa Biochimica et Biophysica Sinica, 2023
Cisplatin resistance is a major obstacle in the treatment of non-small cell lung cancer (NSCLC). p32 and OPA1 are the key regulators of mitochondrial morphology and function. This study aims to investigate the role

The mycotoxin phomoxanthone A disturbs the form and function of the inner mitochondrial membrane. [PDF]

open access: yes, 2018
Mitochondria are cellular organelles with crucial functions in the generation and distribution of ATP, the buffering of cytosolic Ca2+ and the initiation of apoptosis. Compounds that interfere with these functions are termed mitochondrial toxins, many of

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Drosophila Parkin requires PINK1 for mitochondrial translocation and ubiquitinates Mitofusin [PDF]

open access: yes, 2010
Loss of the E3 ubiquitin ligase Parkin causes early onset Parkinson's disease, a neurodegenerative disorder of unknown etiology. Parkin has been linked to multiple cellular processes including protein degradation, mitochondrial homeostasis, and autophagy;

OPA1 and PARL Keep a Lid on Apoptosis [PDF]

open access: yesCell, 2006
A change in the shape of mitochondrial cristae must take place to attain rapid and complete release of cytochrome c during apoptosis. In this issue of Cell, Cipolat et al. and Frezza et al. (2006) show that a rhomboid intramembrane protease PARL and a dynamin-related protein OPA1 are critical regulators of cristae remodeling.

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

open access: yesAdvanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...
