Mammalian frataxin directly enhances sulfur transfer of NFS1 persulfide to both ISCU and free thiols.

Mammalian frataxin directly enhances sulfur transfer of NFS1 persulfide to both ISCU and free thiols. Aubérie Parent, Xavier Elduque, David Cornu, Laura Belot, Jean-Pierre Le Caer, Anna Grandas, Michel B. Toledano, Benoit D’Autréaux; Nature Communications 6, doi:10.1038/ncomms6686, Published 19 January 2015

These data raise important questions on the physiological mechanism of Fe-S cluster assembly and point to a unique function of ​frataxin as an enhancer of sulfur transfer within the ​NFS1–​ISD11–​ISCU complex.

The cerebellum and sleep

The cerebellum and sleep. DelRosso LM, Hoque R; Neurologic clinics 32:4 2014 Nov pg 893-900 doi:10.1016/j.ncl.2014.07.003

The cerebellum has an important role in sleep. Certain sleep disorders have demonstrated decreased activity in the cerebellum, and sleep complaints are common in patients with cerebellar diseases such as spinocerebellar ataxia, Friedreich ataxia, Joubert syndrome, and ataxia-telangiectasia.

ACTIMMUNE, Phase 3 clinical study will begin enrolling patients in the second quarter of 2015. StreetInsider.com, January 12, 2015

It is anticipated that approximately 110 subjects will be screened at four U.S. centers for eligibility to randomize approximately 90 subjects 1:1 to receive either ACTIMMUNE or placebo. The Company anticipates the study will take 18 months to complete.

Mitochondrial proteases and protein quality control in ageing and longevity

Mitochondrial proteases and protein quality control in ageing and longevity. Marie-Paule Hamon, Anne-Laure Bulteau, Bertrand Friguet, Ageing Research Reviews, Available online 8 January 2015, ISSN 1568-1637, http://dx.doi.org/10.1016/j.arr.2014.12.010.

Concomitant increased Lon and ClpP levels and loss of mitochondrial Fe-S proteins have been found in the muscle creatine kinase mouse heart model for Friedreich ataxia. To our knowledge, no Lon mutation has been identified to date in patients enabling the determination of a phenotype associated with a Lon defect. Nevertheless, its involvement in age-related and other diseases may consider using it as target for anti-ageing strategy or disease treatments.

Variations in ClpP levels have been noted in hereditary spastic paraplegia and Friedreich ataxia. As for Lon, due to its its involvement in age-related and other diseases, the Clp protease may be considered as a target for disease treatments or anti-ageing strategy.
