Mitochondrial Membrane Dynamics—Functional Positioning of OPA1

open access: yesAntioxidants, 2018
The maintenance of mitochondrial energetics requires the proper regulation of mitochondrial morphology, and vice versa. Mitochondrial dynamins control mitochondrial morphology by mediating fission and fusion.

OPA1 Isoforms in the Hierarchical Organization of Mitochondrial Functions [PDF]

open access: yesCell Reports, 2017
Summary: OPA1 is a GTPase that controls mitochondrial fusion, cristae integrity, and mtDNA maintenance. In humans, eight isoforms are expressed as combinations of long and short forms, but it is unclear whether OPA1 functions are associated with specific

OPA1 Modulates Mitochondrial Ca2+ Uptake Through ER-Mitochondria Coupling [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2022
Autosomal Dominant Optic Atrophy (ADOA), a disease that causes blindness and other neurological disorders, is linked to OPA1 mutations. OPA1, dependent on its GTPase and GED domains, governs inner mitochondrial membrane (IMM) fusion and cristae ...

Role of inner mitochondrial protein OPA1 in mitochondrial dysfunction by tobacco smoking and in the pathogenesis of COPD

open access: yesRedox Biology, 2021
Background: Chronic lung diseases, such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) are linked to several mitochondrial alterations. Cigarette smoke (CS) alters the structure and function of mitochondria.

Effects of Mitochondrial Dynamics in the Pathophysiology of Obesity

open access: yesFrontiers in Bioscience-Landmark, 2022
Obesity has become an urgent and serious public health challenge with an overwhelming increase over the decades worldwide. The rate of obese children and adolescents has recently accelerated, especially in China.

Adipose tissue-specific ablation of PGC-1β impairs thermogenesis in brown fat

open access: yesDisease Models & Mechanisms, 2022
Impaired thermogenesis observed in mice with whole-body ablation of peroxisome proliferator-activated receptor-γ coactivator-1β (PGC-1β; officially known as PPARGC1B) may result from impaired brown fat (brown adipose tissue; BAT) function, but other ...

OPA1-Exon4b modulates the migration and invasion of hepatocellular carcinoma cells by ATP regulation

open access: yesMitochondrial Communications, 2023
Optic Atrophy 1 (OPA1), a mitochondrial inner protein, is involved in both mitochondrial fusion dynamic and cell apoptosis. OPA1 Exon4b (OPA1-Exon4b) was reported to be downregulated in hepatocellular carcinoma (HCC).

Mitochondrial Fusion Via OPA1 and MFN1 Supports Liver Tumor Cell Metabolism and Growth

open access: yesCells, 2020
Metabolic reprogramming universally occurs in cancer. Mitochondria act as the hubs of bioenergetics and metabolism. The morphodynamics of mitochondria, comprised of fusion and fission processes, are closely associated with mitochondrial functions and are

Opa1 Prevents Apoptosis and Cisplatin-Induced Ototoxicity in Murine Cochleae

open access: yesFrontiers in Cell and Developmental Biology, 2021
Optic atrophy1 (OPA1) is crucial for inner mitochondrial membrane (IMM) fusion and essential for maintaining crista structure and mitochondrial morphology.

The mitochondrial fusion protein OPA1 is dispensable in the liver and its absence induces mitohormesis to protect liver from drug-induced injury

open access: yesNature Communications, 2023
Mitochondria are critical for metabolic homeostasis of the liver, and their dysfunction is a major cause of liver diseases. Optic atrophy 1 (OPA1) is a mitochondrial fusion protein with a role in cristae shaping.
