Le patologie muscolari genetiche sono caratterizzate da una progressiva perdita di massa muscolare che culmina con l'insufficienza funzionale dei muscoli. La terapia genica e cellulare sarebbero la cura per tali patologie tuttavia ci sono seri problemi che ne ostacolano l'utilizzo in campo clinico-terapeutico. Un approccio alternativo è quello di ridurre la degenerazione e la perdita di massa muscolare e di favorire la rigenerazione e la ricostruzione dei muscoli distrofici. Questi due processi sono regolati da vie di segnale intracellulare specifiche, e solo una loro dettagliata descrizione ci permetterebbe di sviluppare nuovi farmaci. Perciò è giustificato studiare i segnali che regolano la perdita di massa muscolare. Il nostro lavoro è proprio focalizzato su questo obiettivo. Abbiamo già identificato che i fattori trascrizionali FoxO e Smad regolano una serie di proteine che fanno perdere massa muscolare e che, invece, il fattore JunB promuove la crescita muscolare. Inoltre abbiamo dimostrato che il sistema autofagico, se alterato, causa una progressiva degenerazione della cellula muscolare. Quindi gli obiettivi del progetto sono:i) identificare i geni che controllano la crescita della massa muscolare, ii) capire come il sistema autofagico mantiene integra la cellula muscolare. Userei diversi approcci molecolari atti ad alterare queste vie di segnale con l'obiettivo di identificarne i componenti critici. Questi risultati porterebbero allo sviluppo di nuovi farmaci o a motivare l'uso di terapie già adoperate in campo clinico per la cura delle patologie muscolari degenerative.
