HDAC8 is an established and validated target for T-cell lymphoma and childhood neuroblastoma. The active site binding pocket of HDAC8 is highly conserved among all zinccontaining representatives of the histone deacetylase family. This explains that most HDACs are unselectively recognized by similar inhibitors featuring a zinc binding group (ZBG), a hydrophobic linker and a head group. Read More

Neuroblastoma is a lethal tumor of the sympathetic nervous system. 8-Hydroxydeoxyguanine (8-OH-dG) formation is a common seen type of oxidative DNA damage, which could be repaired by human oxoguanine glycosylase 1 (hOGG1). To explore the contributing role of gene single nucleotide polymorphisms (SNPs) in neuroblastoma risk, we performed a case-control study by genotyping three SNPs (rs1052133 G>C, rs159153 T>C, rs293795 A>G) in gene.

Background: SIRT4 is a member of the sirtuin family of nicotinamide adenine dinucleotide-dependent enzymes located in the mitochondria, and is involved in regulating energy metabolism, stress response, and cellular lifespan in mammalian cells. However, its function in human neuroblastoma (NB) remains unexplored.
Methods: Expression of SIRT4 in 158 pairs of human NB tumor tissues and adjacent normal tissues collected from March 2009 to October 2012 was analyzed by immunohistochemistry, Western blotting, and real-time fluorescence quantitative PCR. Read More

In this study, the circulating miRNome from diagnostic neuroblastoma serum was assessed for identification of noninvasive biomarkers with potential in monitoring metastatic disease. After determining the circulating neuroblastoma miRNome, 743 miRNAs were screened in 2 independent cohorts of 131 and 54 patients. Evaluation of serum miRNA variance in a model testing for tumor stage, MYCN status, age at diagnosis, and overall survival revealed tumor stage as the most significant factor impacting miRNA abundance in neuroblastoma serum.

Protein kinases undergo large-scale structural changes that tightly regulate function and control recognition by small-molecule inhibitors. Methods for quantifying the conformational effects of inhibitors and linking them to an understanding of selectivity patterns have long been elusive. We have developed an ultrafast time-resolved fluorescence methodology that tracks structural movements of the kinase activation loop in solution with angstrom-level precision, and can resolve multiple structural states and quantify conformational shifts between states.

Neuroblastoma is a common childhood cancer with high mortality. We evaluated the capacity of the flavonoid, isoliquiritigenin (4,2',4'-trihydroxychalcone; ISL) to inhibit cellular proliferation and migration in the human neuroblastoma cell line SH-SY5Y. Incubation of cultured SH-SY5Y cells with 20-100 μM ISL decreased cell confluency (15-70%) after 24 h incubation, while 10-100 μM ISL (24 h) depleted intracellular ATP stores (15-90% vs vehicle-treated control) after 24 h incubation.

Purpose: we characterized the response to the extremely low frequency magnetic field (ELF-MF) in an in vitro model of familial Amyotrophic Lateral Sclerosis (fALS), carrying two mutant variants of the superoxide dismutase 1 (SOD1) gene.
Materials And Methods: SH-SY5Y human neuroblastoma cells, stably over-expressing the wild type, the G93A or the H46R mutant SOD1 cDNA, were exposed to either the ELF-MF (50 Hz, 1 mT) or the sham control field, up to 72 hours. Analysis of i) viability, proliferation and apoptosis, ii) reactive oxygen species generation, and iii) assessment of the iron metabolism, were carried out in all clones in response to the MF exposure.

Neuroblastoma (NB) and malignant melanoma (MM), tumors of pediatric age and adulthood, respectively, share a common origin, both of them deriving from the neural crest cells. Although NB and MM have a different behavior, in respect to age of onset, primary tissue involvement and metastatic spread, the prognosis for high stage-affected patients is still poor, in spite of aggressive treatment strategies and the huge amount of new discovered biological knowledge. For these reasons researchers are continuously attempting to find out new treatment options, which in a near future could be translated to the clinical practice. Read More

A 7-year-old patient with a stage 4 neuroblastoma underwent chemotherapy, surgery, myeloablative therapy, external beam radiotherapy, and Isoretinoin treatment. A posttreatment magnetic resonance examination performed administering gadoteric acid as contrast agent showed 2 new hypervascular hepatic lesions, suspicious for metastases. A second magnetic resonance imaging performed using a liver-specific contrast medium (gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid) demonstrated that these lesions were consistent with treatment-related focal nodular hyperplasia.

Alzheimer's disease (AD), the most common neurodegenerative disorder is characterized by the extracellular deposition of dense amyloid beta plaques. Emerging evidence suggests that the production of these plaques is initiated by the intracellular uptake and lysosomal pre-concentration of the amyloid-beta (Aβ) peptide.

Purpose The aims of this study were to estimate the whole-body absorbed-dose with the Dicentric Chromosome Assay (DCA) (biodosimetry) for I-metaiodobenzylguanidine (I-mIBG) therapy for high-risk neuroblastoma, and to obtain an initial correlation with the physical dosimetry calculated as described by the Medical Internal Radiation Dosimetry formalism (MIRD). Together both objectives will aidobjectives will aid the optimization of personalized targeted radionuclide therapies. Material and Methods A 12 year-old child with relapsed high-risk neuroblastoma was treated with I-mIBG: a first administration with activity <444 MBq/kg was used as a tracer in order to calculate the activity needed in a second administration to achieve a whole body prescribed dose of approximately 4 Gy.

Misfolded proteins with abnormal polyglutamine (polyQ) expansion cause neurodegenerative disorders, including Huntington's disease (HD). Recently, it was found that polyQ aggregates accumulate due to vaccinia-related kinase 2 (VRK2)-mediated degradation of TCP-1 ring complex (TRiC)/Chaperonin-containing TCP-1 (CCT), which has an essential role in the prevention of polyQ protein aggregation and cytotoxicity. The levels of VRK2 are known to be much higher in actively proliferating cells but are maintained at a low level in the brain via an unknown mechanism. Read More

CAR is acknowledged as a substrate involved in many homeostatic pathways and mechanisms and, due to its biochemical properties, as a molecule intertwined with the homeostasis of heavy metals such as copper (Cu). In CNS, Cu excess and dysregulation imply oxidative stress, free-radical production and functional impairment leading to neurodegeneration. Read More

Objectives: We have investigated the impact of endoplasmic reticulum (ER) stress, which is often implicated in neurodegenerative diseases, on the expression of Hrd1, an E3 ubiquitin ligase that plays a central role in the process of ER-associated degradation (ERAD).
Methods: SH-SY5Y neuroblastoma cells, a frequently used model for studying neurotoxicity in dopaminergic neurons and the mechanisms of neurodegeneration associated with Parkinson's disease, and parental SK-N-SH cells were studied.
Results: We demonstrate that ER stress, induced by thapsigargin or tunicamycin, correlates with the increased expression of Hrd1 in both SH-SY5Y and SK-N-SH cells. Read More

The cold-inducible protein RBM3 mediates hypothermic neuroprotection against nitric oxide (NO)-induced cell death. Meanwhile, it is well-known that cyclooxygenase-2 (COX-2) is upregulated by RBM3 in several types of cells; however, it is still unclear whether COX-2 contributes to the neuroprotective effects of mild hypothermia/RBM3 against NO-induced cell death. Using human SH-SY5Y neuroblastoma cells, it was revealed that NO remarkably downregulates the expression of COX-2 at both mRNA and protein levels. Read More

We have recently isolated a new isoform of recombinant manganese superoxide dismutase (rMnSOD) which provides a potent antitumor activity and strongly counteracts the occurrence of oxidative stress and tissue inflammation. This isoform, in addition to the enzymatic action common to all SODs, also shows special functional and structural properties, essentially due to the presence of a first leader peptide that allows the protein to enter easily into cells. Among endogenous antioxidants, SOD constitutes the first line of natural defence against pathological effects induced by an excess of free radicals. Read More
