OBJECTIVES An increased expression of adenine nucleotide translocator (ANT1), found in facioscapulohumeral muscular dystrophy (FSHD), is known to lead to a decrease in nuclear factor-kappaB (NF-kappaB) DNA binding and to sensitize muscle cells to oxidative stress and apoptosis. Receptor for advanced glycation end products (RAGE) mediated by NF-kappaB(More)
Inducible nitric oxide synthase knock-out (iNOS(-/-)) mice are valid models of investigation for the role of iNOS in patho-physiological conditions. There are no available data concerning neuroactive amino acid levels of iNOS(-/-) mice and their behaviour in response to pentylenetetrazole (PTZ). We found no significant differences in the convulsive dose 50(More)
In this study, plasma and platelet taurine content and fluxes were determined in 38 type 2 diabetic patients and in 26 healthy control subjects. Taurine levels in diabetic patients were significantly lower than in control subjects both in plasma (32.1 v 48.6 micromol/L, P = .000) and platelets (148 v 183 nmol/mg protein, P = .043). Platelet taurine uptake(More)
Interleukin-6-deficient (IL-6(-/-)) mice and their normal littermate (WT) were studied to evaluate their susceptibility to seizures induced by electroshock and audiogenic stimuli at different ages. No significant changes in maximal electroshock susceptibility were evidenced between the two strains, while audiogenic seizures (AGS) can be induced only in(More)
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymopathy and hemolytic anemia can be triggered by many drugs, by the ingestion of fava beans, and by metabolic imbalances. Nonetheless, only sporadic reports of hemolytic anemia due to G6PD deficiency in patients with type 1 diabetes mellitus (DM1) have been reported to date. We(More)
Genetic animal models have contributed significantly to our understanding of epilepsy causes. Lethargic mice are considered a valid model of absence epilepsy, which have been shown to possess behavioral, electrographic and pharmacological profiles similar to those of humans with absence epilepsies. Single gene mutations that comprise the beta4 subunit of(More)
OBJECTIVES Idiopathic inflammatory myopathies (IIM), including dermatomyositis (DM), polymyositis (PM), sporadic inclusion-body myositis (s-IBM) and focal myositis (FM) are a heterogeneous group of autoimmune disorders of skeletal muscle. An increased transglutaminase 2 (TG2) expression has been found in DM, PM and s-IBM. The aim of our study was to(More)
Telomere shortening is thought to contribute to premature senescence of satellite cells in Duchenne muscular dystrophy (DMD) muscle. Telomeric repeat binding factor-1 (TRF1) and poly (ADP-ribose) polymerase-1 (PARP1) are proteins known to modulate telomerase reverse transcriptase (TERT) activity, which controls telomere elongation. Here we show that an(More)
Platelet levels of 19 amino acids were measured in 20 outpatients with type 1 (age [mean +/- SE], 35.5 +/- 2.0 years) and 27 with type 2 (age, 58.4 +/- 1.4 years) diabetes, and 20 young (age 33.7 +/- 1.3 years) and 20 older (age 57.4 +/- 1.5 years) healthy volunteers. Platelet levels of most amino acids tended to be lower in patients with type 1 diabetes(More)
