Abstract Introduction Facioscapulohumeral muscular dystrophy 1 (FSHD1) is a relatively common autosomal dominant adult with variable disease penetrance. The caused by shortening of D4Z4 repeat array located near the telomere chromosome 4 at 4q35. This causes activation dormant gene DUX4 , permitting aberrant expression which toxic to muscles. Molecular diagnosis FSHD1 Southern blot hybridization or FISH combing difficult and time consuming, requiring specialist laboratories. As an...

Little is known regarding why a subset of COVID-19 patients exhibited prolonged positivity SARS-CoV-2 infection. Here, we found that with long viral RNA course (LC) high-level IgG antibodies and higher regulatory T (Treg) cell counts compared to those short (SC) in terms load. Longitudinal proteomics metabolomics analyses the patient sera uncovered shedding was associated inhibition liver X receptor/retinoid receptor (LXR/RXR) pathway, substantial suppression diverse metabolites, activation...

Effect of cooking temperature (40–100°C) on changes in protein composition big head carp muscle and exudate was investigated. The results showed that the proportion salt-soluble water-soluble proteins cooked decreased with up to 50°C 60°C, respectively. Alkali-soluble content increased increasing range 40–98°C, while both non-protein nitrogen (NPN) alkali- insoluble no significant change. Content soluble collagen exudates temperature.

Phospholipid phosphatase related 4 (PLPPR4), a neuron-specific membrane protein located at the postsynaptic density of glutamatergic synapses, is putative regulator neuronal plasticity. However, PLPPR4 dysfunction has not been linked to genetic disorders. In this study, we report three unrelated patients with intellectual disability (ID) or autism spectrum disorder (ASD) who harbour de novo heterozygous copy number loss in 1p21.2p21.3, nonsense mutation (NM_014839, c.4C > T, p.Gln2*) and...

Neuronal network reconstruction is a pivotal determinant for functional recovery after spinal cord injury (SCI), the process of which includes synaptogenesis. Slit2 protein has been identified as key regulator axon regeneration and synapse formation in vertebrate. Meanwhile, RhoA converging cascade inhibitory molecules that interrupt synaptic plasticity SCI. In present study, we investigated interaction among Slit2, Robo1, potential roles pathological We showed was decreased, whereas Robo1...
