Changes in fractional protein synthesis rates (FSR) of 4 tissues (muscle, liver, intestine and bone) were assessed in 2 groups of young pigs from weaning, 10 days postpartum, to one week later, after feeding equal amounts of dry diets at 2 levels of protein (15 and 30%). In the meantime, protein and energy balance measurements were performed on the whole body partitioned into 4 components (carc...
Seventy-two crossbred (Large White X Landrace) pigs were used in a 3 X 7 factorial experiment to investigate the response of two strains of boars (strains A and B) and of castrated male pigs (strain B) to seven levels of intake of a single diet (ranging from 5.3 Mcal digestible energy [DE]/d to ad libitum) between 45 and 90 kg live weight. All aspects of growth performance and body composition ...
Transgenic mice over-expressing mutant human amyloid precursor protein (PDAPP mouse) develop several Alzheimer’s disease (AD)-like lesions including an age-related accumulation of amyloid-?-containing neuritic plaques. Although aged, heterozygous PDAPP mice also exhibit synaptic and glial cell changes, that is characteristic of AD pathology, no evidence of neurodegeneration has been observed. T...
Polyubiquitin chain deposition on a target protein frequently leads to proteasome-mediated degradation whereas monoubiquitination modifies target protein property and function independent of proteolysis. Histone monoubiquitination occurs in chromatin and is in nowadays recognized as one critical type of epigenetic marks in eukaryotes. While H2A monoubiquitination (H2Aub1) is generally associate...
The alpha-crystallins are members of the small heat shock protein family of molecular chaperones that have evolved to minimize intracellular protein aggregation; however, they are also implicated in a number of protein deposition diseases. In this study, we employed novel mass spectrometry techniques to investigate the changes in quaternary structure associated with this switch from chaperone t...
Genetic variations in the vacuolar protein sorting 10 protein (Vps10p) family have been linked to Alzheimer's disease (AD). Here we demonstrate deposition of fragments from the Vps10p member sortilin at senile plaques (SPs) in aged and AD human cerebrum. Sortilin changes were characterized in postmortem brains with antibodies against the extracellular and intracellular C-terminal domains. The t...
Progressive supranuclear palsy is a neurodegenerative disease which aVects the brainstem and basal ganglia. Patients present with disturbance of balance, a disorder of downward gaze and L-DOPA-unresponsive parkinsonism and usually develop progressive dysphagia and dysarthria leading to death from the complications of immobility and aspiration. Treatment remains largely supportive but, potential...
BACKGROUND/AIMS The endoplasmic reticulum (ER) stress protein, calreticulin (CRT), is required for the production of TGF-β-stimulated extracellular matrix (ECM) by fibroblasts. Since TGF-β regulates vascular fibroproliferative responses and collagen deposition, we investigated the effects of CRT knockdown on vascular smooth-muscle cell (VSMC) fibroproliferative responses and collagen deposition...
