Title:
Advanced human iPSC-based modelling of LMNA-related congenital muscular dystrophy enables development of targeted genetic therapies for muscle laminopathies | bioRxiv
Description:
LMNA -related congenital muscular dystrophy (L-CMD) is amongst the most severe forms of laminopathies, which are diseases caused by pathogenic variants in the LMNA gene. LMNA encodes the proteins LAMINs A and C, which assemble with LAMIN B1 and B2 to form the nuclear lamina: a meshwork providing structural stability to the nucleus that also regulates chromatin organisation and gene expression. Research into L-CMD mechanisms and therapies i hindered by lack of humanised, tissue-specific models that accurately recapitulate disease phenotypes. We previously reported that LMNA -mutant induced pluripotent stem cell (iPSC)-derived skeletal muscle cells have nuclear shape abnormalities and LAMIN A/C protein mislocalisation. Here, we expand the selection of L-CMD patient-derived iPSCs and validate disease-associated readouts using a transgene-free based protocol which more accurately mimics skeletal myogenesis. Results showed no defects in developmental myogenesis, but recapitulation of pathological nuclear shape abnormalities in 2D and 3D cultures, nuclear envelope protein mislocalisation and transcriptomic alterations across multiple pathogenic LMNA variants. We then utilised this platform to assess LMNA gene editing strategies. CRISPR-based exon removal generated stable RNA and protein LAMIN A/C species, without significant normalisation of nuclear morphological phenotypes. Conversely, precise editing of the same mutation showed complete reversal of disease-associated nuclear morphometrics. Our data provide the foundation for a humanised in vitro disease and therapy modelling platform for this complex and severe muscle disorder. ![Figure][1]</img> HIGHLIGHTS ### Competing Interest Statement The authors have declared no competing interest.
