In glutaric aciduria type 1 (GA1), glutaryl-CoA dehydrogenase (GCDH) deficiency has been shown to be responsible for the accumulation of glutaric acid and striatal degeneration. However, the mechanisms by which GA1 induces striatal degeneration remain unclear. In this study, we aimed to establish a novel neuronal model of GA1 and to investigate the effects(More)
Glutaric acid (GA) has been implicated in the mechanism of neurodegeneration in glutaric aciduria type I. In the present study, the potential cytotoxic effects of GA (0.1~50 mM for 24~96 h) were examined in cultured primary rat striatal neurons. Results showed increase in the number of cells labeled by annexin-V or with apoptotic features shown by(More)
Acquired partial lipodystrophy (APL) is a rare disorder, mainly characterized by progressive loss of subcutaneous fatty tissue, starting from the face and spreading to the upper part of the body. The etiology of APL is unknown. It may be caused by mutations in the lamin B 2 (LMNB2) gene on 19p13.3. We present a Chinese patient who hadAPL for 12 years, which(More)
Intrauterine growth retardation (IUGR) has been linked to metabolic syndrome including insulin resistance, and overexpression of suppressors of cytokine signaling (SOCSs) proteins is thought to be associated with increased whole-body insulin sensitivity. The insulin-resistant IUGR rat model was established by maternal food restriction (about 30% of the(More)
A 2.75-year-old Chinese boy presented with typical clinical features of pseudoachondroplasia, including disproportionate short-limb short stature, brachydactyly, genu varus and waddling gait. Radiologically, tubular bones were short with widened metaphyses, irregular and small epiphyses; anterior tonguing or beaking of vertebral bodies were characteristic.(More)
In previous study, glutaric acid (GA) induced apoptosis of primary striatal neuron in vitro. In order to investigate the neurotoxic effects of GA on neonatal rat corpus striatum and the possible mechanism, 34 male pups were randomly assigned to NS group, low dose GA (LGA, 5 μmol GA/g body weight) group and high dose GA (HGA, 10 μmol GA/g body weight) group.(More)
Acute neurological crises involving striatal degeneration induced by a deficiency of glutaryl-CoA dehydrogenase (GCDH) and the accumulation of glutaric (GA) and 3-hydroxyglutaric acid (3-OHGA) are considered to be the most striking features of glutaric aciduria type I (GA1). In the present study, we investigated the mechanisms of apoptosis and energy(More)
