Neuroblastomas and cell lines derived from these tumors bear the oncodevelopmental antigen polysialic acid (PSA) bound to the neural cell adhesion molecule. Polysialyation of neural cell adhesion molecule can be achieved by two different polysialyltransferases, ST8SiaII and ST8SiaIV. This study was undertaken to investigate the pattern of polysialyltransferases expressed in the human neuroblast...
Adaptive changes in gene expression are thought to contribute to dependence, addiction and other behavioral responses to chronic ethanol abuse. DNA array studies provide a nonbiased detection of networks of gene expression changes, allowing insight into functional consequences and mechanisms of such molecular responses. We used oligonucleotide arrays to study nearly 6000 genes in human SH-SY5Y ...
Physiological modifications of intracellular Ca2+ ([Ca2+]i) levels trigger and/or regulate a diversity of cellular activities (e.g. neurotransmitter release, synaptic plasticity, muscular contraction, cell proliferation), while calcium overloads could result in cytotoxicity. Previously, we have shown that trimethyltin chloride (Me3SnCl; TMT) modulates calcium homeostasis in cervix adenocarcinom...
This work aims at investigating the neuroprotective effects of neuroglobin (Ngb) in vivo and in vitro. RT-PCR and Western blotting were used to examine Ngb mRNA and protein levels in the mouse cortex after acute and repeated exposure to hypoxia. The cDNAs of mouse Ngb were cloned and transfected into SH-SY5Y cells to examine Ngb function in vitro. Expression of Ngb and mRNA was upregulated in t...
Human cytomegalovirus (HCMV) is the leading viral cause of birth defects, affecting primarily the central nervous system (CNS). To further understand this CNS pathology, cells from glioblastoma cell lines T98G and A172, the astrocytic glioblastoma cell line CCF-STTG1 (CCF), and the neuroblastoma cell line SH-SY5Y (SY5Y) were infected with HCMV. CCF and SY5Y cells were fully permissive for infec...
Chemoresistance is a major problem during cancer treatment. ATP-binding cassette (ABC) transporter efflux is mainly responsible for this chemotherapeutics resistance of the tumour cells. We have recently observed that in the presence of statins SH-SY5Y neuroblastoma cells show enhanced susceptibility to doxorubicin-induced apoptosis which cannot be explained by simple additivity. In order to mo...
Human neuroblastoma cells, SH-SY5Y, contain relatively low levels of thioredoxin (Trx); thus, they serve favorably as a model for studying oxidative stress-induced apoptosis (Andoh, T., Chock, P. B., and Chiueh, C. C. (2001) J. Biol. Chem. 277, 9655-9660). When these neurotrophic cells were subjected to nonlethal 2-h serum deprivation, their neuronal nitric oxide synthase and Trx were up-regula...
We investigated whether altering caveolin-2 (cav-2) expression affects the proliferation of cancer cells. Cav-2 was not detected in HepG2, SH-SY5Y and LN-CaP cells, and the loss of cav-2 expression was not restored by 5-aza-2'-deoxycytidine treatment. In contrast, C6, HeLa, A549, MCF7 and PC3M cells expressed cav-2. Effects of re-expression of exogenous cav-2 in HepG2, SH-SY5Y and LN-CaP cells,...
The endogenous neurotoxin, 1-methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline (salsolinol), has been considered a potential neurotoxin in the etiology of Parkinson's disease (PD). Salsolinol and N-methyl(R)-salsolinol were identified in the brains and cerebrospinal fluid (CSF) of PD patients. Oxidative stress is known to be one of the major contributing factors in the cascade that may finall...
Neuron-virus interactions that occur during herpes simplex virus (HSV) infection are not fully understood. Neurons are the site of lifelong latency and are a crucial target for long-term suppressive therapy or viral clearance. A reproducible neuronal model of human origin would facilitate studies of HSV and other neurotropic viruses. Current neuronal models in the herpesvirus field vary widely ...
