- Site-specific Mtm1 mutagenesis by an AAV-Cre vector reveals that myotubularin is essential in adult muscle.
- Joubert R, Vignaud A, Le M, Moal C, Messaddeq N, Buj-Bello A.AbstractManipulation of the mouse genome by site-specific mutagenesis has been extensively used to study gene function and model human disorders. Mouse models of myotubular myopathy (XLMTM), a severe congenital muscular disorder due to loss-of-function mutations in the MTM1 gene, have been generated by homologous recombination and shown that myotubularin is essential for skeletal muscle. However, since the Mtm1 deletion occurred constitutively or shortly after birth in these mice, it is not known whether myotubularin is required during adulthood, an important issue in the context of not only muscle biology but also therapies. To delete the Mtm1 gene in adult muscle fibers, we constructed a recombinant adeno-associated vector (AAV) that expresses the Cre recombinase under the muscle-specific desmin promoter. We report that a single injection of this vector into muscles of 3-month-old Mtm1 conditional mice leads to a myotubular myopathy phenotype with myofiber atrophy, disorganization of organelle positioning, such as mitochondria and nuclei, T-tubule defects and severe muscle weakness. In addition, our results show that MTM1-related atrophy and dysfunction correlate with abnormalities in satellite cell number and markers of autophagy, protein synthesis and neuromuscular junction transmission. The expression level of atrogenes was also analyzed. Therefore, we provide a valuable tissue model that recapitulates the main features of the disease, and it is useful to study pathogenesis and evaluate therapeutic strategies. We establish the proof-of-concept that myotubularin is required for the proper function of skeletal muscle during adulthood, suggesting that therapies will be required for the entire life of XLMTM patients.

- Functional analysis of a duplication (p.E63_D69dup) in the switch II region of HRAS: new aspects of the molecular pathogenesis underlying Costello syndrome.
- Lorenz S, Lissewski C, Simsek-Kiper PO, Alanay Y, Boduroglu K, Zenker M, Rosenberger G.AbstractCostello syndrome is a congenital disorder comprising a characteristic face, severe feeding difficulties, skeletal, cardiac and skin abnormalities, intellectual disability and predisposition to malignancies. It is caused by heterozygous germline HRAS mutations mostly affecting Gly(12) or Gly(13), which impair HRAS-GTPase activity and result in increased downstream signal flow independent of incoming signals. Functional analyses of rarer HRAS mutations identified in individuals with attenuated Costello syndrome phenotypes revealed altered GDP/GTP nucleotide affinities (p.K117R) and inefficient effector binding (p.E37dup). Thus, both phenotypic and functional variability associated with HRAS mutations are evident. Here, we report on a novel heterozygous HRAS germline mutation (c.187_207dup, p.E63_D69dup) in a girl presenting with a phenotype at the milder end of the Costello syndrome spectrum. The p.E63_D69dup mutation impaired co-precipitation of recombinant HRAS with NF1 GTPase-activating protein (GAP) suggesting constitutive HRAS(E63_D69dup) activation due to GAP insensitivity. Indeed, we identified strongly augmented active HRAS(E63_D69dup) that co-precipitated with effectors RAF1, RAL guanine nucleotide dissociation stimulator and phospholipase C1. However, we could not pull down active HRAS(E63_D69dup) using the target protein PIK3CA, indicating a compromised association between active HRAS(E63_D69dup) and PIK3CA. Accordingly, overexpression of HRAS(E63_D69dup) increased steady-state phosphorylation of MEK1/2 and ERK1/2 downstream of RAF, whereas AKT phosphorylation downstream of phosphoinositide 3-kinase (PI3K) was not enhanced. By analyzing signaling dynamics, we found that HRAS(E63_D69dup) has impaired reagibility to stimuli resulting in reduced and disrupted capacity to transduce incoming signals to the RAF-MAPK and PI3K-AKT cascade, respectively. We suggest that disrupted HRAS reagibility, as we demonstrate for the p.E63_D69dup mutation, is a previously unappreciated molecular pathomechanism underlying Costello syndrome.
