Amyotrophic lateral sclerosis (ALS) is a lethal motor neuron disease that progressively debilitates neuronal cells that control voluntary muscle activity. Biomarkers are urgently needed to facilitate ALS diagnosis and prognosis, and as indicators of therapeutic response in clinical trials. microRNAs (miRNAs), small posttranscriptional modifiers of gene(More)
The choice of housekeeping proteins or genes for internal standards should be made carefully, taking into account the cell and tissue type, the experimental conditions, and the healthy/disease state(s) under consideration. Furthermore, as the correlation between transcriptional and translational levels of commonly used housekeeping genes is often discussed,(More)
During postnatal growth and after muscle injury, satellite cells proliferate and differentiate into myotubes to form and repair musculature. Comparison of studies on satellite cell proliferation and differentiation characteristics is confounded by the heterogeneity of the experimental conditions used. To examine the influence of sex, age, and fiber-type(More)
The nontoxic proteolytic C fragment of tetanus toxin (TTC peptide) has the same ability to bind nerve cells and be retrogradely transported through a synapse as the native toxin. We have investigated its potential use as an in vivo neurotropic carrier. In this work we show that a hybrid protein encoded by the lacZ-TTC gene fusion retains the biological(More)
BACKGROUND In the superoxide dismutase 1 (SOD1)-G93A mouse model of amyotrophic lateral sclerosis (ALS), skeletal muscle is a key target of mutant SOD1 toxicity. However, the expression of factors that control the regenerative potential of the muscle is unknown in this model. OBJECTIVE To characterize the expression of satellite cell marker Pax7 and(More)
BACKGROUND Amyotrophic lateral sclerosis (ALS) is the most common adult-onset neurodegenerative disease characterized by ascending muscle weakness, atrophy and paralysis. Early muscle abnormalities that precede motor neuron loss in ALS may destabilize neuromuscular junctions, and we have previously demonstrated alterations in myogenic regulatory factor(More)
We developed and evaluated a PCR procedure to detect pork in heated and unheated meat, sausages, canned food, cured products, and pâtés using a faster, more specific, and more sensitive method than others previously described. Isolation of a new DNA-specific porcine repetitive element was performed by nonspecific PCR amplification. After analyzing this(More)
Because some fraudulent or unintentional mislabeling occurs that can be undetected, resulting in lower quality pâté, and because some population groups, for philosophical or religious reasons, do not wish to eat meat from certain species, a new procedure was developed and evaluated to detect pâté species composition by randomly amplified polymorphic DNA(More)
Amyotrophic lateral sclerosis (ALS) is an adult onset neurodegenerative disease that causes progressive paralysis and death due to degeneration of motoneurons in spinal cord, brainstem and motor cortex. Nowadays, there is no effective therapy and patients die 2–5 years after diagnosis. Resveratrol (trans-3,4′,5-trihydroxystilbene) is a natural polyphenol(More)
