Hox-C9 activates the intrinsic pathway of apoptosis and is associated with spontaneous regression in neuroblastoma [tumor_genex_44k]

ABSTRACT: Single-color gene expression profiles from 649 neuroblastoma tumors were generated using 44K oligonucleotide microarrays. We aimed at determining the association of class I HOX gene expression patterns with prognostic markers in neuroblastoma.We investigated the functional consequences of HOXC9 re-expression on neuroblastoma growth and programmed cell death. One-color gene expression analysis.

One-color gene expression analysis. Single-color gene expression profiles from 649 neuroblastoma tumors were generated using 44K oligonucleotide microarrays. Stages were classified according to the International Neuroblastoma Staging System. The expression patterns of the 39 class I HOX genes were analyzed in 649 neuroblastoma samples by microarrays, and the association with prognostic markers was determined.

Hox-C9 activates the intrinsic pathway of apoptosis and is associated with spontaneous regression in neuroblastoma [cell line_genex_44k]

Project description:Single-color gene expression profiles from 2 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. To gain insights into the molecular processes occurring upon HOXC9 re-expression, we analyzed gene expression profiles of IMR-32 and SK-N-AS cells after Hox-C9 induction using microarrays. We used gene ontology (GO) annotations to find classes of genes that are significantly over-represented in gene sets that were either up- or downregulated after HOXC9 re-expression. One-color gene expression analysis Single-color gene expression profiles from 2 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. Total RNA of HOXC9- and GFP-expressing SK-N-AS and IMR-32 cells was isolated at 0, 6, 12, 24, 48 and 96 h using Trizol. To determine global differences in the expression profiles of HOXC9- and GFP-induced SK-N-AS and IMR-32 cells, mean expression levels of each gene between HOXC9-induced and control (GFP) cells were compared. Gene Ontology Tree Machine (GOTM) was used to identify functional categories associated with the condition of the respective cell line.
