In this study, we investigated the role of autophagy and apoptosis in Newcastle disease virus (NDV)-infected chicken cells and tissues. NDV-infected and starvation-induced chick embryo fibroblasts (CEF) cells showed higher autophagosome formation than mock-infected CEF cells on transmission electron microscopy. The NDV-infected CEF cells showed enhanced conversion of microtubule-associated prot...

Glycogen synthase kinase-3β (GSK-3β) plays an important role in the regulation of apoptosis. To investigate its involvement in acquired cadmium (Cd) resistance, Cd-resistant cells (RH460) were established from H460 lung carcinoma cells. Cd resistance led to interruption of apoptosis and autophagy, as determined by an apoptotic sub-G1 population, procaspase-3 clevage, and LC3-II induction. Cd-in...

BACKGROUND Some patients treated with chloroquine, hydroxychloroquine, or colchicine develop autophagic vacuolar myopathy, the diagnosis of which currently requires electron microscopy. The goal of the current study was to develop an immunohistochemical diagnostic marker for this pathologic entity. METHODOLOGY Microtubule-associated protein light chain 3 (LC3) has emerged as a robust marker o...

Objective(s): The aim of this study was to explore the effects of Squid ink polysaccharide (SIP) on prevention of autophagy and oxidative stress induced by cyclophosphamide (CP) in Leydig cells of mice. Materials and Methods: Examination of reproductive organ exponents, abnormal sperm rate, activities of superoxide dismutase (SOD), catalase (CAT), contents of malondialdehyde (MDA), and histolog...

Bovine aortic endothelial cells (BAECs) were cultured with high glucose (33 mmol/L), 4 mg/L green tea polyphenols (GTPs) or 4 mg/L GTPs co-treatment with high glucose for 24 h in the presence or absence of Bafilomycin-A1 (BAF). We observed that high glucose increased the accumulation of LC3-II. Treatment with BAF did not further increase the accumulation of LC3-II. Results also showed an increa...

Metallic nanoparticles (mNPs) are widely used as food additives and can interact with gliadin triggering an immune response, but evaluation of the effects on crypts, hypertrophic in celiac subjects, is still lacking. This study evaluated gold silver mNPs combination crypt-like cells (HIEC-6). Transmission electron microscopy (TEM) was to evaluate gliadin-mNP aggregates cells. Western blot immun...

Incorporation of ubiquitin and ubiquitin-related proteins including p62 into neuronal intranuclear inclusions (NIIs) has been reported in a variety of neurodegenerative diseases. However, involvement of autophagy-specific proteins (NBR1 and LC3) in NIIs has not been mentioned. We immunohistochemically examined the brain of patients with Machado-Joseph disease (MJD; n=5), dentatorubral-pallidolu...

The aim of this study was to investigate the effects of erythropoietin (EPO) on the impairment of autophagy induced by lipopolysaccharide (LPS) in primary cultured rat glomerular mesangial cells (GMCs). Rat GMCs were isolated and cultured in normal glucose, high-glucose, LPS or LPS + EPO medium. At 24 and 72 h of culture, the cells were examined for expression levels of the autophagy markers LC...
