Abstract The effect of hypoxia on the release of tumor necrosis factor-α (TNF-α) in transformed rat retinal ganglion cells (RGCs) and the effect of agmatine on the hypoxia-induced production of TNF-α in RGCs were evaluated. RGCs were cultured under hypoxic conditions with 5% oxygen, with or without 100 μM agmatine. The expression levels of TNF-α and its receptor-1 (TNF-R1) were investigated by Western blot analysis. After 6 hours of hypoxia, we noted an increase in TNF-α production in RGCs. Agmatine significantly reduced TNF-α level after 12 hours of hypoxic treatment. The expression of TNF-R1 was not affected by the hypoxia or… More >

Abstract The neonatal hypoxic–ischemic encephalopathy (HIE) is an important cause of neurological morbidity and mortality in neonates. Cell therapy is considered a promising method for treating severe neurological disorders such as this one. Stem cells have the capacity for self-renewal and differentiation into certain cell lineages. The present study was aimed to find out the most beneficial route of bone marrow-derived mesenchymal stem cells (BMSCs) administration for the attenuation of experimentally induced HIE in neonatal rats. Sixty neonatal rats were divided randomly into four groups. Group 1: control group. Group 2: rats were exposed to bilateral ligation of cephalic arteries. Group… More >
