Yi-Zhi-Fang-Dai formula (YZFDF) is an experiential prescription used to cure dementia cases like Alzheimer's disease (AD). In this study, the main effective compounds of YZFDF have been identified from this formula, and the neuroprotective effect against Aβ1-42 oligomer of YZFDF has been tested in SH-SY5Y cells. Our results showed that YZFDF could increase cell viability and could attenuate end...

Biatractylolide, isolated from the ethyl acetate extract of Atractylodes macrocephala, has shown various pharmacological activities such as antitumor and antioxidant activities. In this work, we aim to study the protective effect of biatractylolide on glutamate-induced rat adrenal pheochromocytoma cell (PC12) and human bone marrow neuroblastoma cell line (SH-SY5Y) injury and preliminarily explo...

SH-SY5Y human neuroblastoma cells provide a useful in vitro model to study the mechanisms underlying neurotransmission and nociception. These cells are derived from human sympathetic neuronal tissue and thus, express a number of the Cav channel subtypes essential for regulation of important physiological functions, such as heart contraction and nociception, including the clinically validated pa...

Human cell lines are often used to investigate cellular pathways relevant for physiological or pathological processes or to evaluate cell toxicity or protection induced by different compounds, including potential drugs. In this study, we analyzed and compared the differentiating activities of three agents (retinoic acid, staurosporine and 12-O-tetradecanoylphorbol-13-acetate) on the human neuro...

Nerve growth cones of primary neurons are highly enriched in the proto-oncogene product pp^'TM. In order to investigate this molecule further in growing neuronal cells, growth cone and cell body fractions were prepared from human SH-SY5Y neuroblastoma cells differentiated neuronally in vitro under the influence of phorbol ester. The fractions were characterized ultrastructurally and by biochemi...

The actions of tumor promoters on the coupling of muscarinic receptors to the hydrolysis of inositol lipids and the generation of Ca2+ signals were examined in the human neuroblastoma SH-SY5Y cell line. Pretreatment of SH-SY5Y cells with 50 nM 12-O-tetradecanoylphorbol 13-acetate (TPA) for 5 days resulted in neuronal differentiation, a 28% decrease in both N-[3H]methylscopolamine and [3H]-scopo...

Mutations in the gene encoding the purine biosynthetic enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT) cause the intractable neurodevelopmental Lesch-Nyhan disease (LND) associated with aberrant development of brain dopamine pathways. In the current study, we have identified an increased expression of the microRNA miR181a in HPRT-deficient human dopaminergic SH-SY5Y neuroblastoma c...

Objective: To establish cell model of herpes simplex virus type 2 latent infection and reactivation in SHSY5Y cells. Methods: Effects of ACV on SH-SY5Y cells were observed after cells were treated with ACV concentrations of 20, 40, 60, 80, 100, 120, or 140 μmol/L, and also cells morphology was observed under phase contrast microscope after HSV-2 was inoculated into SH-SY5Y cells using MOI of 0....

An oxidative stress insult is one of the principal causes of Parkinson's disease. Astragaloside IV (AS-IV), a constituent extracted from Astragalus membranaceus, has been demonstrated to exert antioxidant effects. However, the mechanisms responsible for the antioxidant properties and neuroprotective effects of AS-IV remain unclear. In this study, we examined the protective effects of AS-IV agai...

Introduction: The neuroprotective role of opioid morphine against 6-hydroxydopamineinduced cell death has been demonstrated. However, the exact mechanism(s) underlying such neuroprotection, especially the role of subtype receptors, has not yet been fully clarified. Methods: Here, we investigated the effects of different opioid agonists on 6-OHDA-induced neurotoxicity in human neuroblastoma...
