Project description:To elucidate potential role of piRNAs in Neuroblastoma (NB), we performed the genome wide profiling in two human NB cell lines, IMR-32 and SH-SY-5Y by adopting high-throughput RNA sequencing (RNA-Seq) and unveil their possible functions in neoplastic pathways. The RNA sequencing results revealed both known and novel piRNAs in both the cell lines. We observed a total 630 annotated mature piRNAs, distributed across chromosomes and mitochondria which were mapped to various genomic locations such as introns, protein coding regions, repeats, pseudogenes, ncRNAs etc. This is the first study reporting the extensive catalogue of human NB piRNAs which will provide a useful resource to dissect complex neoplastic events that are possibly mediated by piRNAs in neuroblastoma. Moreover, these piRNAs could be used as probable small RNA biomarkers for the Neuroblastoma.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
Project description:ALK is a tyrosine kinase receptor and oncogene in neuroblastoma (NB). The receptor is activated by the ALKAL2 ligand, but it is unknown whether missregulation of this ligand may play a role in NB carcinogenesis. To characterize the transcriptomic response to ALKAL2 in neuroblastoma cell lines, RNA-Seq was performed on NB1 and IMR32 human NB cell lines.
Project description:Microarray-based genome-wide measurements of copy number alterations and of transcriptome variations are proposed for neuroblastoma prognosis and possible treatment choice. Nonetheless, they lack to provide clues on a neglected layer of systems-level changes, the translatome, whose variations are defined by the activity of the translational regulatory machinery. Our study extends the conventional genome-wide approaches to translatome profiling in neuroblastoma, by means of polysomal sucrose gradient separation followed by microarray analysis. The panel of fourteen parental (not subcloned) neuroblastoma cell lines used in the study includes: CHP-134, SIMA, NB-69, LAN-1, KELLY, CHP-126, CHP-212, SK-N-BE(2), IMR-32, SK-N-AS, SK-N-SH, STA-NB-7, STA-NB-1, STA-NB-10 cells. Each cell line has been profiled with high resolution array CGH analysis for copy number changes, and for transcriptome and translatome variations. The integration of these three types of data sets obtained from the same cells can provide information on the impact in neuroblastoma of a defined pattern of genomic lesions on both transcriptional and translational alterations of gene expression.

Project description:In the present study we investigated the structure of MYCN amplifications, examples of both dmin and hsr, in eight neuroblastoma (NB) and two small cell lung carcinoma (SCLC) cell lines. Ten cell lines were analyzed for gene amplification: STA-NB3 (NB), STA-NB4 (NB), STA-NB8 (NB), STA-NB10DM (NB), STA-NB10HSR (NB), STA-NB13 (NB), STA-NB15 (NB), SK-N-BE (NB), GLC8 (SCLC), GLC14 (SCLC). NimbleGen human reference sample was used as reference DNA.
