Neurological Disease Modeling Using Pluripotent and Multipotent Stem Cells: A K...

Despite extensive research, the links between the accumulation of glycosaminoglycans (GAGs) and the clinical features seen in patients suffering from various forms of mucopolysaccharidoses (MPSs) have yet to be further elucidated. This is particularly true for the neuropathology of these disorders; the neurological symptoms are currently incurable, even in the cases where a disease-specific therapeutic approach...

Exploring an antisense oligonucleotide exon-skipping therapeutic strategy for M...

Introduction: Mucolipidosis II (ML II) is a Lysosomal Storage Disorder caused by the deficiency of the enzyme GlcNAc-1-phosphotransferase, which is responsible for the Mannose-6-Phosphate marker addition to lysosomal enzymes. Of all ML II mutations, the c.3503_3504delTC in GNPTAB exon 19 is the most frequent, making it a good target for a personalized therapy. Here, we explored an innovative therapeutic strateg...

Development of Engineered-U1 snRNA Therapies: Current Status

Splicing of pre-mRNA is a crucial regulatory stage in the pathway of gene expression. The majority of human genes that encode proteins undergo alternative pre-mRNA splicing and mutations that affect splicing are more prevalent than previously thought. Targeting aberrant RNA(s) may thus provide an opportunity to correct faulty splicing and potentially treat numerous genetic disorders. To that purpose, the use of...

Splicing Modulation as a Promising Therapeutic Strategy for Lysosomal Storage D...

Over recent decades, the many functions of RNA have become more evident. This molecule has been recognized not only as a carrier of genetic information, but also as a specific and essential regulator of gene expression. Different RNA species have been identified and novel and exciting roles have been unveiled. Quite remarkably, this explosion of novel RNA classes has increased the possibility for new therapeuti...

The 2020s Tooth Fairy: from loose tooth to neuronal cell cultures, an innovativ...

The development of adequate in vitro disease models is a major issue in Biomedical Genetics. Those models allow for the initial screening of novel therapeutics and help us get an insight on the cellular mechanisms that underly pathology in each case. In fact, one of the best ways to get those insights is the analysis of patient-derived cells. Yet, not every cell holds potential to recapitulate relevant disease ...

The disease modelling value of baby teeth: A new way to unlock knowledge about ...

Mucopolysaccharidoses (MPS), are a group of genetic, metabolic, and rare diseases investigated since the early years of the 20th century. One of the first steps to collect information about the underlying mechanisms of those disorders is the development and analysis of in vitro models. Furthermore, those models provide an appropriate platform for the evaluation of future therapeutics. Among all the possible dis...

Development of an antisense oligonucleotides-based therapy for mucolipidosis ty...

Introduction: The RNA molecule has become an increasingly promising target for the therapy of various diseases. Mucolipidosis type II α/β (ML II α/β) is one of the most severe Lysosomal Storage Disorders and is caused by the deficiency of the enzyme GlcNAc-1- phosphotransferase. This enzyme is responsible for the addition of the mannose 6-phosphate (M6P) marker to lysosomal enzymes, which allow their targeting ...
