The study on the accumulation of neutral lipids in fibroblasts of NLSD-M, starting with the Telethon project (GGP14066) will be continued. Experiments will be carried out on fibroblast cultures and iPSC cells in metabolic diseases by testing pharmacological agents for the reduction of lipid accumulation. New mutations in lipid diseases will be sought from ETFDH defect and in other cases of lipid myopathies. We will use engineered myoblast and fibroblasts cultures as a model for the study of the mechanisms that lead to this pathology, in particular investigating the role of TNPO3 in muscle.

In neuroimaging studies, widespread brain alterations, such as general atrophy, reduction of the volume of gray matter in all four lobes and the cerebellum have been documented. The prevalence of hyperintensities localized in white matter is estimated to be around 70% in DM1. Tractography analysis shows an increase in mean diffusivity in all four lobes and a reduction of fractional anisotropy in the main white matter traits. Functional studies also demonstrate a reduced capacity of glucose uptake and cerebral perfusion in the frontal, parietal, and temporal lobes and anomalous connectivity observed by fMRI. However, the significant differences emerged in the different studies are obtained with the use of different brain imaging methods. Moreover, we would like to determine if differences found are due to a developmental or to a neuronal degenerative process.

 The first aim is to investigate P-14-3-3 specific interactors using proteomics screens. The second aim is to assess whether PAK6-mediated 14-3-3 phosphorylation decreases the neuroprotective effect on as aggregation process in vitro and in cells. The third aim is to develop and implement novel biomarker assays monitoring P-14-3-3 and P-PAK6 in human with Parkinson specimens.

The project aims are to identify patients with unknown myopathies by genetic analysis, to follow-up with MRI quantified using Mercuri score muscle evolution and compare it with functional status of patients such as GSGC scale. We expect to verify consistent finding between GSGC score, muscle imaging and other parameters as muscle groups muscle MRC score.

We propose to investigate the serum molecular biomarkers that reflect the consequence of muscle atrophy and to observe the changes in level expression of microRNAs and correlate them with the MRI analysis. Furthermore, the medical genetic staff of the University of Milano will help us in this study with the fibroblast culture of these patients for the future study. New therapies could be found by understanding the mechanism of muscle atrophy and cellular content of triglycerides.

We propose to observe the changes in the level expressions of microRNAs that they might influence the mitochondrial metabolism by acting on it; in fact, they could increase the production of ROS, or modulate the expression of specific genes by increasing apoptosis. We studied the regulation of Er- mitochondria contact by Parkin in parkin mutant fibroblasts and in Drosophila models. We also would like to investigate the role of OX/PHOS proteins complexes and the alterations of production of cytochrome oxidase complex. MicroRNAs could be a valid biomarker for investigating the damage in hearing pathways and in several mitochondrial diseases. Future researchers could be needed for testing these biomarkers in prospective human clinical studies.

The study on biopsies of patients with genetic ALS (with mutations in C9orf, SOD1 gene) and sporadic has the aim to highlight the tissue-related differences of microRNA and protein expression and compared it with clinical features. We propose to investigate the circulating miRNAs in patients affected by several conditions and their correlation with muscle atrophy and clinical/instrumental evaluation. The effects of rehabilitation in patients with ALS, DM1, and Hereditary Spastic Paraparesis hospitalized in our center is one of our specific aim: a multidisciplinary approach based on molecular and protein biomarkers, clinical parameters and outcome scales will be done.
