Newsletter #74

Welcome to the 74th issue of our newsletter!

Odile Boesflug-Tanguy, neuropediatrician and researcher, has taken the direction of I-Motion since last July 16 following the departure of Laurent Servais to whom we wish all success and whom we thank for all that he built at l’Institut de Myologie with his team. We also wish Teresa Gidaro all the best as she leaves the institute and warmly thanks her for the work she did in the I-Motion centre for research. Ongoing trials are proceeding and new trials will soon be launched and monitored. Thus, alongside her work as Chair of the Scientific Council of the AFM-Téléthon at the level of basic and preclinical research, Odile Boesflug-Tanguy will be involved in the next step in the process: the trials in patients.

Until our next issue in September, we wish you all an enjoyable and safe summer!

At the Institute
“REDs” team 4 from Research Centre in the spotlight at IDMC-12 Three members of Denis Furling's team ("Repeat Expansions & Myotonic Dystrophy") have been rewarded at the 12th International Myotonic Dystrophy Consortium Meeting (IDMC-12) which brings together, every 2 years, leading scientists specialising in myotonic dystrophy from all over the world.

66 participants: all time record for our 2019 Summer School! The 22nd edition of the Summer School of Myology took place from June 17th to 22nd. Every year, the Institute offers the possibility to get trained in Myology thanks to a condensed 6-day course organized in Paris. The course is open to foreign applicants whichever country they come from. There were 66 student representing 26 nationalities, all time record! Read more

Two gene therapy trials underway at I-Motion Of the roughly 20 clinical trials underway at I-Motion, two concern gene therapy, which constitutes one of the preferred approaches to treating genetic diseases: ASPIRO concerns myotubular myopathy, and STR1VE-EU concerns type 1 proximal spinal muscular atrophy linked to SMN1.

SMA gene therapy: it is becoming possible to defeat the disease At a time when the first gene therapy for spinal muscular atrophy has just received US marketing authorisation, the first French children are starting to benefit from this treatment. Next expected stage: marketing authorisation in Europe. Read more

Our latest news
CRISPR-Cas9 : first in vivo proof-of-concept in DM1 Thanks to this genome editing approach, the expanded CTG triplet repeat in the DMPK gene, which is responsible for the disease, was “cut” and removed from the gene, and the number of toxic RNA aggregates was decreased in the muscle cells of the tested models.

Development and validation of a new risk prediction score for life-threatening ventricular tachyarrhythmias in Laminopathies An accurate estimation of this risk in patients with LMNA mutations is crucial to select candidates for implantable cardioverter-defibrillator implantation. Read more

Alteration of performance in a mouse model of Emery-Dreifuss muscular dystrophy caused by A-type lamins gene mutation The researchers here have deepened the knowledge on performance in this mouse model of Emery-Dreifuss muscular dystrophy. Read more

Biomarkers in inflammatory myopathies - an expanded definition Biomarkers as parameters of pathophysiological conditions are particularly warranted to inform about diagnostic, prognostic, and therapeutic questions. Read more

Inhibition of myostatin improves muscle atrophy in OPMD In OPMD, this strategy has implications to be used as adjuvant therapies with gene therapy based approaches, or to stabilize the muscle prior to myoblast transplantation. Read more

LRSAM1 variants and founder effect in French families with ataxic form of CMT2 The clinicians aimed to identify the causative gene of CMT type 2 in 8 non-related French families with a distinct clinical phenotype. They collected clinical, electrophysiological, and laboratory findings and performed genetic analyses. Read more

Causes and Consequences of miR-150-5p Dysregulation in Myasthenia Gravis The researchers showed that the microRNA miR-150-5p, previously described as a biomarker of MG, could play a role in MG both at the thymic level and in periphery by modulating the expression of target genes and peripheral cell survival. Read more

Newborn screening for SMA in Southern Belgium The authors developed and validated a newborn screening method to specifically recognize homozygous deletions of exon 7 in the SMN1 gene. Then, a 3-year pilot study has been recently initiated in one Belgian neonatal screening laboratory to cover 17.000 neonates per year. Read more
