GSE145336 19p loss is significantly enriched in older age neuroblastoma patients and correlates with poor prognosis (Agilent-013282, dataset 1)
Contributor : Annalisa PezzoloSeries Type : Genome variation profiling by arrayOrganism : Homo sapiensGenomic aberrations of neuroblastoma occurring in late childhood and adolescence are uncommon and still underestimated.Public DNA copy number profiles of 556 tumors (discovery set) and of 208 tumors obtained by array-CGH assay (validation set) were used to verify if 19p loss is significantly over-represented in children and adolescents. The 19p loss occurrence was separately tested within different age groups in the discovery and validation set and the resulting P values were combined and corrected by Bonferroni ’s method.In both sets, the lowest age group significantly associated with 19p loss (discovery set: 20%; validation set: 35%) was 6 years. The 19p loss was considered to be a significant marker for overall survival in patients over 6 years of age. Relevant tumor suppressor genes (KEAP1, DNM2, SMARCA4, SLC44A2 and CDKN2D) and microRNAs (miR-181c, miR-27a, and mirR-199a-1) were in 19p loss. Down-regulation of DNM2, SLC44A2 and CDKN2D associated with poor patient outcome and older age. Among the recurrent NB chromosomal aberrations, only 1q gain was enriched in patients older than 6 years and was mutually exclusive respect to 19p loss.Our data demonstrate that 19p loss is a genomic biomarker of NBs diagnosed in older children that can predict clinical outcome.

Abstract Guided by computational analysis, herein we report the design, synthesis and evaluation of four novel diazine-based histone deacetylase inhibitors (HDACis). The targets of interest (TOI) are analogues of panobinostat, one of the most potent and versatile HDACi reported. By simply replacing the phenyl core of panobinostat with that of a diazine derivative, docking studies against HDAC2 and HDAC8 revealed that the four analogues exhibit inhibition activities comparable to that of panobinostat. Multistep syntheses afforded the visualized targets TOI1, TOI2, TOI3-rev and TOI4 whose biological evaluation confirmed the ...

The Krukenberg tumor is a rare metastatic adenocarcinoma (ADK) in the ovary, representing 1-2% of ovarian tumors. Multiple primary malignant neoplasms may exist when more than one cancerous tumor is diagnosed in the same or a different organ. The incidence of multiple primary cancers among malignancies is between 2...
Conclusion: Adrenal gland tumors of childhood with complex immunophenotypic features requires distinguishing two discrete tumors in the small round blue cell tumor group, neuroblastoma and Ewing sarcoma. Although no exact diagnosis of the tumor was made, we reached a good response with neuroblastoma treatment protocol. PMID: 32242756 [PubMed - as supplied by publisher]
Despite intensive multimodal therapy, the survival rate for high risk neuroblastoma (HR-NB) remains
CONCLUSION: The results suggest that resveratrol promotes the catalytic activity of xenobiotic metabolizing enzyme, Cyp2d22/CYP2D6, which partially contributes to Nrf2 activation in pesticides-induced Parkinsonism. PMID: 32242774 [PubMed - as supplied by publisher]
CONCLUSIONS: The obtained data indicate that mirtazapine and imipramine have neuroprotective effects against H2O2-induced cell death. Although both antidepressants reduced Bax and p53 mRNA expression, only the protection mediated by imipramine might be due to its ability to enhance Bcl-2/Bax ratio.

In this study, we explored the neuroprotective effects of miR-219a-5p on brain using an in vitro ischemia model (mouse neuroblastoma N2a cells treated with oxyglucose deprivation and reperfusion), and in vivo cerebral I/R model in mice.
In this study, ferritin fusion protein (FFP) was combined with Tet expression construct under a modified immediate-early gene (IEG) Arc/Arg3.1 promoter so-called SARE-ArcMin. This expression system is a neuronal activity-dependent expression module for nano-ferritin, a radio/magnetic wave-sensitive protein well-accepted as a potential recombinant neuronal actuator. The system was characterized in transcriptional and translational levels in human neuroblastoma SH-SY5Y cells. The mRNA and protein expression levels of nano-ferritin were significant in the activated neurons suggesting that the activity dependent expression pat...
