MSN and Friedreich ataxia: Baciu et al. profiled circulating microvesicle proteins by LC/MS [56] in the plasma of DTC and FA patients and HCs and found that two proteins, cell division control protein 42 homolog (CDC42) and Moesin (MSN), both implicated in tumourigenesis in many cancers, were significantly lower in plasma microvesicles from DTC patients and HCs compared to FA patients.
