Mutations of the survival of motor neuron gene (SMN1) are responsible for spinal muscular atrophies (SMA), a frequent recessive autosomal motor neuron disease. SMN is involved in various processes including RNA metabolism. However, the molecular pathway linking marked deficiency of SMN to SMA phenotype remains unclear. Homozygous deletion of murine Smn exon 7 directed to neurons or skeletal muscle causes severe motor axonal or myofiber degeneration, respectively. With the use of cDNA microarrays ...[more]

Trancriptional regulation by axonal SMN on motor neuron cells

Project description:Muscular atrophy (SMA) is an autosomal recessive disease causing selective motor neuron death by the loss of telomeric survival motor neuron gene, SMN1. Axonal SMN, a-SMN, is a truncated form of SMN, derived from an alternatively spliced SMN1 gene. (Setola, et. al. 2007 PNAS 104, 1959-1964). The cellular clones expressing a-SMN in a tetracycline-dependent manner were isolated from NSC34 by two-step stable transfection, first with the tetracycline-repressor construct and subsequently with the a-SMN cDNA. To identify novel a-SMN target genes, the transcriptome of several a-SMN clones was analyzed and compared with that of parental cells.

Neurochondrin interacts with the SMN protein suggesting a novel mechanism for Spinal Muscular Atrophy pathology.

Project description:Spinal Muscular Atrophy (SMA) is an inherited neurodegenerative condition caused by reduction in functional Survival Motor Neurones Protein (SMN). SMN has been implicated in transport of mRNA in neural cells for local translation. We previously identified microtubule-dependant mobile vesicles rich in SMN and SmB, a member of the Sm family of snRNP-associated proteins, in neural cells. By comparing the interactomes of SmB and SmN, a neural-specific Sm protein, we now show that the essential neural protein neurochondrin (NCDN) interacts with Sm proteins and SMN in the context of mobile vesicles in neurites. NCDN has roles in protein localisation in neural cells, and in maintenance of cell polarity. NCDN is required for the correct localisation of SMN, suggesting they may both be required for formation and transport of trafficking vesicles. NCDN may have potential as a therapeutic target for SMA together with, or in place of, those targeting SMN expression

Muscle from patients with mitochondrial myopathies and congenital muscular dystrophies versus normal human muscle

Project description:Global gene expression analysis was performed comparing human skeletal muscle samples from patients with various forms of muscular dystrophy and mitochondrial myopathies in order to identify specific gene expression changes associated with collagen VI deficiency (leading to UllrichM-BM-4s Congenital Muscular Dystrophy) and depletion of mitochondrial DNA relative to other mitochondrial myopathies We analysed the gene expression profile of skeletal muscle from children suffering from mitochondrial myopathies and various forms of muscular dystrophy relative to skeletal muscle from healthy children using commercially available arrays that represents the complete human genome (Agilent Human SurePrintGE, 8x60K )

Mass spectrometry-based proteomic comparison of BirA-SMN, BirA-SMN-Y109C and BirA proxisomes.

Project description:Although recent advances in gene therapy provide hope for spinal muscular atrophy (SMA) patients, the pathology remains the leading genetic cause of infant mortality. SMA is a monogenic pathology that originates from the loss of the SMN1 gene in most cases or mutations in rare cases. Interestingly, SMN1 mutations occur broadly either within the TUDOR methyl-arginine (Rme) reader domain of SMN or its carboxy terminal oligomerization domain. We hypothesized that in SMN1 mutant cases, SMA may emerge from aberrant protein-protein interactions between SMN and key neuronal factors. Using a proximity-dependent biotinylation proteomic (BioID) approach, we have identified and validated a number of SMN-interacting proteins, including Fragile X mental retardation family members (FMRFM), such as FMRP itself as well as FXR1 and FXR2, some depending on a wild-type version of the TUDOR domain.
