Way of Identifying What Protects Frataxin May Help in Slowing FA

Levels of the protein frataxin, which are abnormally low in people with Friedreich’s ataxia (FA), are further reduced by excess iron and increased protein degradation, a study found. Screening approved compounds in a yeast model identified those that prevented this additional frataxin loss in cells isolated from a patient,…

Smoothened Agonist May Normalize Defects in Brain Cells With FA

Astrocytes, a type of support cell in the brain, showed metabolic defects and unusual pro-inflammatory activity that likely contributes to neuronal dysfunction in a cell model of Friedreich’s ataxia (FA), according to a new study. Results also indicate that treatment with a molecule called smoothened agonist (SAG) can normalize…
