The vitamin A metabolite, all-trans retinoic acid (atRA), plays an important role in neuronal development, including neurite outgrowth. However, the genes that lie downstream of atRA and its receptors in neuronal cells are largely unknown. By using the human neuroblastoma cell line, SH-SY5Y, we have identified an atRA-responsive gene (RAINB1: retinoic acid inducible in neuroblastoma cells) that...
The onset and progression of Alzheimer's disease is characterized by the aggregation 42-residue form amyloid-β peptide (Aβ42). Significant evidence indicates that mechanism which Aβ42 induces cell death through interaction its toxic oligomeric species with membranes, results in disruption membrane integrity homeostatic processes within cell. Moreover, there interacts differentially regions memb...
The active form of vitamin D3 and some of its related compounds show neuroprotective effects in various models of neuronal damage, however, mechanism of their anti-apoptotic action has not been elucidated. Therefore, the present study was designed to investigate the effects of 1,25-dihydroxyvitamin D3 and its low-calcemic analogues, PRI-2191, PRI-1890 and PRI-1901 on staurosporine-induced apopt...
Ischemic stroke is an acute vascular event that obstructs blood supply to the brain, producing irreversible damage that affects neurons but also glial and brain vessel cells. Immediately after the stroke, the ischemic tissue produces nitric oxide (NO) to recover blood perfusion but also produces superoxide anion. These compounds interact, producing peroxynitrite, which irreversibly nitrates pro...
SH-SY5Y human neuroblastoma cells can be induced to differentiate to mature ganglion cells when treated with the phorbol ester tetradecanoylphorbol acetate (TPA). Bryostatins are a new class of protein kinase C activators that are structurally unrelated to phorbol esters. This paper describes the effects of bryostatins 1 and 2 on morphological and functional differentiation of SH-SY5Y cells. Bo...
Objective: This study aimed to assess the enhanced anticancer effect of Temozolomide (TMZ) through a synergistic combination with Diltiazem (DTZ) in neuroblastoma cell line (SH-SY5Y).
 Material and Methods: The SH-SY5Y was cultured DMEM medium. TMZ DTZ stock solutions were prepared diluted obtain different concentrations. XTT assay performed evaluate viability. Cells treated alone or for 2...
The folate and cobalamin (Cbl-) dependent enzyme methionine synthase (MS) is highly sensitive to oxidation and its activity affects all methylation reactions. Recent studies have revealed alternative splicing of MS mRNA in human brain and patient-derived fibroblasts. Here we show that MS mRNA in SH-SY5Y human neuroblastoma cells is alternatively spliced, resulting in three primary protein speci...
Alzheimer's disease (AD) is a fatal neurodegenerative disease. Brain amyloid-β deposition is a crucial feature of AD, causing neuronal cell death by inducing oxidative damage. Reactive oxygen species (ROS) activate NF-κB, which induces expression of Nucling. Nucling is a pro-apoptotic factor recruiting the apoptosome complex. Lycopene is an antioxidant protecting from oxidative stress-induced c...
Oxidative stress and free radical production have been implicated in Alzheimer's disease, where low levels of the antioxidant vitamin C (ascorbate) have been shown to be associated with the disease. In this study, neuroblastoma SH-SY5Y cells were treated with hydrogen peroxide in the presence of ascorbate in order to elucidate the mechanism(s) of protection against oxidative stress afforded by ...
