N88S seipin mutant transgenic mice develop features of seipinopathy/BSCL2-related motor neuron disease via endoplasmic reticulum stress.

Heterozygosity for mutations (N88S and P90L) in the N-glycosylation site of seipin/BSCL2 is associated with the autosomal dominant motor neuron diseases, spastic paraplegia 17 and distal hereditary motor neuropathy type V, referred to as 'seipinopathies'. Previous in vitro studies have shown that seipinopathy-linked mutations result in accumulation of unfolded proteins in the endoplasmic reticu...

Mutant Profilin1 transgenic mice recapitulate cardinal features of motor neuron disease.

The recent identification of profilin1 mutations in 25 familial ALS cases has linked altered function of this cytoskeleton-regulating protein to the pathogenesis of motor neuron disease. To investigate the pathological role of mutant profilin1 in motor neuron disease, we generated transgenic lines of mice expressing human profilin1 with a mutation at position 118 (hPFN1G118V). One of the mouse ...

Alleviation of seipinopathy-related ER stress by triglyceride storage.

Mutations affecting the N-glycosylation site in Berardinelli-Seip lipodystrophy (BSCL)-associated gene BSCL2/seipin lead to a dominantly inherited spastic paraplegia termed seipinopathy. While the loss of function of seipin leads to severe congenital lipodystrophy, the effects of seipin N-glycosylation mutations on lipid balance in the nervous system are unknown. In this study, we show that exp...

Endoplasmic reticulum stress response in P104L mutant caveolin-3 transgenic mice.

Mutations in the caveolin-3 gene cause autosomal dominant limb-girdle muscular dystrophy 1C (LGMD1C). However, the precise molecular pathogenesis of caveolin-3-related muscular dystrophy remains uncertain. Here, we demonstrate the effect of gene dosage on the severity of the myopathic phenotype in P104L mutant caveolin-3 (mCav3(P104L)) transgenic mice, a model of LGMD1C. We analyzed the endopla...

Endoplasmic reticulum stress regulates inflammation in adipocyte of obese rats via toll-like receptors 4 signaling

Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...
