The present study aims to investigate the role of p73 in response to cisplatin treatment in p53 wild-type neuroblastoma SH-SY5Y cells. Results showed that cisplatin induced a dose-dependent up-regulation of p53, p73, and a number of p53-responsive genes. Interestingly, endogenous Deltaexon2p73-expression was down-regulated by cisplatin treatment. Neither p21 nor GADD45 induction was observed in...

In this study, in vitro blood-brain barrier (BBB) models composed of two different cell types were compared. The aim of our study was to find an alternative human cell line that could be used in BBB models. Inorganic and organic mercury and aluminum were studied as model chemicals in the testing of the system. BBB models were composed of endothelial RBE4 cell line or retinal pigment epithelial ...

Parkinson's disease (PD) is characterized by selective loss of dopaminergic neurons in the substantia nigra of the brain. Although the underlying causes are not well characterized, epidemiological studies suggest an elevated risk of PD with occupational pesticide exposure. Here, we utilized pheochromocytoma (PC) 12 and SH-SY5Y cells as well as rat primary cultured dopaminergic neurons to invest...

Exposure to an excess amount of manganese causes neurological symptoms similar to Parkinson's disease. Zinc transporters such as Zrt, Irt-related protein 8 (ZIP8), and ZIP14 have been shown to have affinities for Mn(2+) as well as Zn(2+), but their roles in Mn(2+) uptake in neuronal cells remain unclear. Recent studies have shown that another zinc transporter ZnT10 may be involved in manganese ...

Electronically conductive and electrochemically active 3D-scaffolds based on electrospun poly(ethylene terephthalate) (PET) nano-fibers are reported. Vapour phase polymerization was employed to achieve an uniform and conformal coating of poly(3,4-ethylenedioxythiophone) doped with tosylate (PEDOT:tosylate) on the nano-fibers. The PEDOT coatings had a large impact on the wettability, turning the...

The active ingredient of ginseng, ginsenosides Rg1, has been shown to scavenge free radicals and improve antioxidant capacity. This study hypothesized that ginsenosides Rg1 has a protective role in human neuroblastoma cells injured by H2O2. Ginsenosides Rg1 at different concentrations (50 and 100 μM) was used to treat H2O2 (150 μM)-injured SH-SY5Y cells. Results demonstrated that ginsenoside Rg...

1 The D3 dopamine receptor presumably activates Gi/Go subtypes of G-proteins, like the structurally analogous D2 receptor, but its signalling targets have not been clearly established due to weak functional signals from cloned receptors as heterologously expressed in mostly non-neuronal cell lines. 2 In this study, recombinant human D3 receptors expressed in a human neuroblastoma cell line, SH-...

Ropinirole (ROP) is a dopamine agonist that has been used as therapy for Parkinson's disease. In the present study, we aimed to detect whether gene expression was modulated by ROP in SH-SY5Y cells. SH-SY5Y cell lines were treated with 10 µM ROP for 2 h, after which total RNA was extracted for whole genome analysis. Gene expression profiling revealed that 113 genes were differentially expressed ...

Cytokine-like 1 (CYTL1) was first identified in CD34+ cells derived from bone marrow and cord blood. The biological functions of CYTL1 remain largely unknown. Here, we reveal a relationship between CYTL1 expression and the biological characteristics of neuroblastoma (NB). The expression of CYTL1 was detected in 10 human tumor cell lines and human NB tissues by RT-PCR and real-time PCR. The inhi...

It has been reported that cornin may reduce neuronal death during cerebral ischemia; however, little is known about the molecular mechanism of the role of corninin autophagy in SH‑SY5Y neuronal cells. In the present study, oxygen‑glucose deprivation (OGD)‑treated cells were used as a cerebral ischemia model in vitro. The results demonstrated that cornin was able to reduce neuronal cell loss, in...
