Dux4-Regulated Expression and Activity by an inhibitor Molecule

Project description

A novel therapy against muscular dystrophy

Facioscapulohumeral muscular dystrophy (FSHD) is a prevalent muscle disease caused by the aberrant myogenic expression of the transcription factor double homeobox 4 (DUX4), which activates apoptosis and triggers muscle wasting. Scientists of the EU-funded DREAM project have identified the first direct DUX4 inhibitor with putative therapeutic value. The scope of DREAM is to elucidate the mechanism of inhibitor function and develop a drug-like molecule capable of blocking the aberrant activity of DUX4 in muscle cells of FSHD patients. The project's results will shed light on FSHD pathogenesis and bring us a step closer to a rational treatment for FSHD.

Objective

Facioscapulohumeral muscular dystrophy (FSHD) is the most prevalent muscle disease that indiscriminately afflicts children and adults of all ages and both sexes. Despite several clinical trials, there continues to be no cure or therapeutic option available to FSHD patients.
FSHD is caused by aberrant myogenic expression of the transcription factor double homeobox 4 (DUX4). In healthy subjects, DUX4 expression is restricted to stem cells and early stages of embryogenesis while being silenced in most tissues of the body. In FSHD, DUX4 mis-expression activates a pro-apoptotic transcriptional program leading to muscle wasting.
Compelling data obtained in our laboratory identified a novel regulator of DUX4 that allows us to examine the potential of inhibiting the cytotoxic activity of DUX4 as a therapeutic strategy to treat FSHD, and represents the innovation of this proposal. The goal of the proposal is to fully elucidate the molecular mechanisms that regulate DUX4 in order to develop novel therapeutic approaches for blocking the aberrant activity of DUX4 in FSHD.
Based on our preliminary data, I hypothesize that by inhibiting DUX4 we can prevent transcriptional activation of genes toxic to muscle cells.
As a corollary, we propose that a drug-like molecule interfering with the DUX4 pathway could be used to prevent the toxic effects of DUX4 expression in muscle cells from FSHD patients. This work is significant as it will clarify the molecular pathogenesis of the disease and bring us closer to a rational treatment to block muscle degeneration in FSHD.
