| pubmed-article:19701497 | pubmed:abstractText | Neuroblastoma (NB) is the most common extracranial solid neoplasm of infancy and childhood. Whereas most low-risk patients do well, children with high-risk tumors often fail intensive treatment. Identification of novel biomarkers is critical to improve prognostication, tailor therapy, and develop new therapeutic targets. Differential RNA-level expression between tumor cells with neuroblastic (N-type) and Schwannian stromal (S-type) phenotypes was used to identify genes of potential interest based on tumor cell type-specific regulation. Gene expression microarray analysis revealed marked differences between N-type and S-type cells in their levels of BCL6 messenger RNA, a transcriptional regulator overexpressed in a variety of hematopoietic malignancies. S-type cells express higher levels of Bcl6 RNA and protein than N-type, and protein levels are significantly limited by proteasome function. An NB tumor tissue microarray linked to clinicopathologic data was immunohistochemically stained to measure Bcl6 protein levels. Bcl6 was detected in both the neuroblastic and Schwannian stromal regions, as distinguished histologically, and correlated with outcome. We found that expression in neuroblastic regions differentiates outcomes, in that Bcl6 expression in neuroblastic regions is associated with increased time to relapse and increased overall survival compared with absent expression in neuroblastic regions, regardless of Schwannian stromal expression. Thus, our findings suggest that Bcl6 may be useful as a prognostic marker and might represent a potential therapeutic target for high-risk NB. | lld:pubmed |
