Mitochondrial dysfunction in an Opa1 (show MED12 Antibodies) mouse model of dominant optic atrophy results from Opa1 (show MED12 Antibodies) haploinsufficiency.
TNFR2 (show TNFRSF1B Antibodies) activation protects cardiac myocytes against stress by up-regulating OPA1 (show MED12 Antibodies) expression.
OPA1 (show MED12 Antibodies) mutant mice are resistant to age- and diet-induced weight gain and insulin (show INS Antibodies) resistance, by mechanisms that involve activation of endoplasmic reticulum stress and secretion of fibroblast growth factor 21 (FGF21 (show FGF21 Antibodies)) from skeletal muscle, resulting in increased metabolic rates and improved whole-body insulin (show INS Antibodies) sensitivity.
OPA1 (show MED12 Antibodies) modulates cristae morphology but is dispensable for cristae junction formation. Endogenous OPA1 (show MED12 Antibodies) and MIC60 show a physical interaction.
Opa1 (show MED12 Antibodies) deficiency was associated with increased sensitivity to Ischemia-Reperfusion Injuries, imbalance in dynamic mitochondrial Ca2 (show CA2 Antibodies)+ uptake, and subsequent increase in NCX (show SLC8A1 Antibodies) activity.
Whereas Parkin (show PARK2 Antibodies) has been reported to positively regulate the expression of OPA1 (show MED12 Antibodies) through NEMO (show IKBKG Antibodies), herein we found that PARK2 (show PARK2 Antibodies) overexpression did not modify the expression of OPA1 (show MED12 Antibodies).
stress-induced OMA1 (show OMA1 Antibodies) activation and guanosine triphosphatase OPA1 (show MED12 Antibodies) cleavage limit mitochondrial fusion and promote neuronal death
Data suggest that in a mouse model of neonatal hypoxic-ischemic brain injury, the expression of mitochondrial shaping proteins, such as OPA1 (show MED12 Antibodies) and Yme1L (show YME1L1 Antibodies), are altered; in vitro and in vivo, OPA1 (show MED12 Antibodies) is cleaved to shorter forms and Yme1L (show YME1L1 Antibodies) expression is reduced.
results indicate that the OPA1 (show MED12 Antibodies)-dependent cristae remodeling pathway is a fundamental, targetable determinant of tissue damage in vivo.
cristae shape amelioration by controlled Opa1 (show MED12 Antibodies) overexpression improves two mouse models of mitochondrial disease.
The splice site mutation (c.985G>T) identified in the present study led to exon 10 skipping (c.985_1065del, p.V329_D355del), suggesting loss-of-function of the GTPase (show RACGAP1 Antibodies) domain of the OPA1 protein, which is likely to cause haplo-insufficiency, a major disease mechanism in DOA.
study identifies a novel pathogenic OPA1 mutation and shows that it is located in the transcript region not prone for NMD activation
OPA1 gene screening in patients with bilateral optic atrophy is an important part of clinical evaluation as it may establish correct clinical diagnosis
OPA1 and cardiolipin cooperate in heterotypic mitochondrial inner membrane fusion.
We propose that OPA1 stabilizes respiratory chain supercomplexes in a conformation that enables respiring mitochondria to compensate a drop in Deltapsim by an explosive matrix pH flash.
We report the first cases of genetically confirmed OPA1-related autosomal-dominant optic atrophy from Singapore, including a novel mutation causing 'ADOA plus' syndrome.
contrary to conventional notion, S-OPA1 is fully competent for maintaining mitochondrial energetics and cristae structure
we analyzed ophthalmological data of a multicentre OPA1 patient cohort and found that women undergo more severe visual loss at adolescence and greater progressive thinning of the retinal nerve fibres than males. Thus, we disclosed a gender-dependent effect on ADOA severity, involving for the first time steroids and Muller glial cells, responsible for RGC degeneration.
The gene signature of OPA1, CTSA (show CTSA Antibodies), NDUFA1 (show NDUFA1 Antibodies), STK10 (show STK10 Antibodies) and PRDX1 (show PRDX1 Antibodies) was able to identify patients post-implant with a sensitivity of 91% and a specificity of 86% in discrimination between post-implant group and healthy controls.
The architecture of dendritic arborization in patients with OPA1 mutations is not known, but our data support the idea that loss of dendritic arborization may be involved in the pathogenesis of DOA rather than just population loss.
Opa1 is required for proper mitochondrial metabolism in early development
This gene product is a nuclear-encoded mitochondrial protein with similarity to dynamin-related GTPases. It is a component of the mitochondrial network. Mutations in this gene have been associated with optic atrophy type 1, which is a dominantly inherited optic neuropathy resulting in progressive loss of visual acuity, leading in many cases to legal blindness. Multiple transcript variants encoding different isoforms have been found for this gene.
