Mass populations of thyrocytes stably expressing wild type RET/PTC1 oncogene or RET/PTC1 carrying Y451F mutation and parental thyrocytes were used for hybridization on Affymetrix HG-U133A and HG-U133B chips. For each cell condition were generated two different targets (indicated as two different samples in the database, i.e. "Parental Thyrocytes" and "Parental Thyrocytes bis")for a total number of six samples. For the data analysis the two samples from the same condition (i.e. Parental thyrocytes) were considered as duplicates.

View SamplesThe transgenic mice expressing the human mutated form (G93A) of the SOD1 gene represent a valuable model of Amyotrophic Lateral Sclerosis (ALS). SOD1 is one of the main causative genes of familial ALS which accounts for 10% of cases. These transgenic animals develop a motorneuronal pathology that recapitulates well the neuropatological features occuring in ALS patients, and the progression of the disease can be monitored by a series of motor tests. Gastrocnemius is first and most affected muscle in the disease, while triceps is relatively spared.

View SamplesExtremely variable clinic and genetic features characterize Mitochondrial Encephalomyopathy Disorders (MED). Pathogenic mitochondrial DNA (mtDNA) defects can be divided into large-scale rearrangements and single point mutations. Clinical manifestations become evident when a threshold percentage of the total mtDNA is mutated. In some MED, the "mutant load" in an affected tissue is directly related to the severity of the phenotype. However, the clinical phenotype is not simply a direct consequence of the relative abundance of mutated mtDNA. Other factors, such as nuclear background, can contribute to the disease process, resulting in a wide range of phenotypes caused by the same mutation. Using Affymetrix oligonucleotide cDNA microarrays (HG-U133A), we studied the gene expression profile of muscle tissue biopsies obtained from 12 MED patients (4 common 4977-bp deleted mtDNA and 8 A3243G: 4 PEO and 4 MELAS phenotypes) compared with age-matched healthy individuals.

View SamplesSpinal Muscular Atrophy (SMA) is an autosomal recessive motor neuron disease and is the second most common genetic disorder leading to death in childhood. No effective therapy is currently available. It has been suggested that -lactam antibiotics such as ceftriaxone may offer neuroprotection in motoneuron disease. We investigated the therapeutic effect of ceftriaxone in a murine model of SMA.

View SamplesSpinal Muscular Atrophy (SMA) is an autosomal recessive motor neuron disease and is the second most common genetic disorder leading to death in childhood. Motoneurons derived from induced pluripotent stem cells (iPS cells) obtained by reprogramming SMA patient and his healthy father fibroblasts, and genetically corrected SMA-iPSC obtained converting SMN2 into SMN1 with target gene correction (TGC), were used to study gene expression and splicing events linked to pathogenetic mechanisms.

View SamplesSpinal Muscular Atrophy (SMA) is an autosomal recessive motor neuron disease and is the second most common genetic disorder leading to death in childhood. Stem cell transplantation could represent a therapeutic approach for motor neuron diseases such as SMA. We examined the theraputics effects of a spinal cord neural stem cell population and their ability to modify SMA phenotype.
Neural stem cell transplantation can ameliorate the phenotype of a mouse model of spinal muscular atrophy.
