1. This study demonstrated that mouse model of Friedreich's ataxia showed that decreased grip strength endurance time , threshold of peripheral sensitivity using Von Frey monofilaments and gait parameters. PMID: 27575947
2. Here, the authors show that loss of Fxn in the nervous system in mice also activates an iron/sphingolipid/PDK1/Mef2 pathway, indicating that the mechanism is evolutionarily conserved. PMID: 27901468
3. The in vitro antioxidant treatments trigger the axonal re-growth and the increase in stable MTs in shFxn, thus contributing to identify new neuronal targets of oxidation in this disease and providing a novel approach for antioxidant therapies. PMID: 27516386
4. Retinal FXN levels are increased in response to ischemia. Furthermore, elevated FXN levels had a clear neuroprotective effect as shown by increased ganglion cell survival after acute retinal ischemia/reperfusion. Frataxin's neuroprotective effect was associated with an upregulation of antioxidative enzymes. PMID: 27537261
5. Frataxin Deficiency Promotes Excess Microglial DNA Damage and Inflammation that Is Rescued by PJ34 PMID: 26954031
6. Frataxin-deficient mice, which had higher mitochondrial iron loading, showed impaired airway mucociliary clearance and higher pulmonary inflammation at baseline. PMID: 26752519
7. Using a mouse model of hepatic FXN deficiency in combination with mice deficient for IRP1, a key regulator of cellular iron metabolism, we show that IRP1 activation in conditions of Fe-S deficiency increases the available cytosolic labile iron pool PMID: 25651183
8. The Fxn KO/Mck mice tested from one to two months of age showed abnormal gait patterns accompanied by a loss in motor skills PMID: 25765157
9. Reduced expression of frataxin in Friedreich's ataxia leads to elevation of COX2-mediated oxylipin synthesis stimulated by increases in transcription factors that respond to increased reactive oxygen species. PMID: 25104852
10. Frataxin-deficient cells showed a specific inhibition of mitochondrial Complex I activity already at 70% residual frataxin levels, whereas the glutathione imbalance progressively increased after silencing. PMID: 24714088
11. The results support a mechanistic hypothesis in which frataxin deficiency decreases Nrf2 expression in vivo, causing the sensitivity to oxidative stress in target tissues the DRG and the cerebella, which contributes to the process of neurodegeneration. PMID: 23350650
12. rescue of the Friedreich ataxia knockout mutation in transgenic mice containing an FXN-EGFP genomic reporter PMID: 24667739
13. these results indicate that IGF-I exerts cell-context neuroprotection in frataxin deficiency that maybe therapeutically effective. PMID: 23039828
14. Data show that the respiratory chain defects accompanying frataxin deficiency cause progressive hyperacetylation of cardiac mitochondrial proteins due to the inhibition of SIRT3 deacetylase. PMID: 22394676
15. dual, pro-proliferative but chemosensitizing role in astrocytic tumors PMID: 21863062
16. Distribution of frataxin in eye retina of normal mice and of transgenic R7E mice with retinal degeneration PMID: 20799613
17. As an attempt to generate a mouse model of Friedreich ataxia, we introduced a (GAA)(230) repeat within the mouse frataxin gene by homologous recombination. PMID: 11852098
18. studies indicate an association between frataxin deficiency, iron deposits and cardiac fibrosis, but no obvious association between iron accumulation and neurodegeneration similar to Friedreich ataxia could be detected PMID: 12880182
19. frataxin has a role in cellular growth arrest and apoptosis, and its absence can cause experimental diabetes PMID: 12925693
20. We have generated two mouse models for FRDA that specifically develop progressive mixed cerebellar and sensory ataxia, the most prominent neurological features of Friedreich ataxia with a slowly progressive neurological degeneration PMID: 14985441
21. frataxin may act as a mitochondrial tumor suppressor protein PMID: 16278235
22. The identification of a core set of genes changing early in the FRDA pathogenesis can be a useful tool in both clarifying the disease process and in evaluating new therapeutic strategies. PMID: 16442805
23. Reduced expression of mitochondrial frataxin in mice exacerbates diet-induced obesity. PMID: 17404227
24. The fxn GAA repeat expansion mutation induces comparable epigenetic changes in human and transgenic mouse brain and heart. PMID: 18045775
25. loss of Fxn markedly alters cellular Fe trafficking and Fe chelation limits myocardial hypertrophy in the mutant PMID: 18621680
26. Frataxin deficiency causes upregulation of mitochondrial Lon and ClpP proteases and severe loss of mitochondrial Fe-S proteins. PMID: 19154341
27. The PPARG pathway is dysregulated in frataxin deficient mice and Friedreich's ataxia patients. PMID: 19376812
28. We showed that complete absence of murine frataxin in fibroblasts inhibits cell division and leads to cell death. This lethal phenotype was rescued through transgenic expression of human wild type as well as mutant (hFXN(G130V) and hFXN(I154F)) frataxin PMID: 19629184
29. Results enable the construction of a model explaining the cytosolic iron deficiency and mitochondrial iron loading in the absence of frataxin, which is important for understanding the pathogenesis of Friedreich's ataxia. PMID: 19805308
