Protein Expression in Human Neuroblastoma Tumor Samples
RATIONALE: Studying protein expression in samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors find better ways to treat neuroblastoma.
PURPOSE: This laboratory studying is looking at protein expression in tumor tissue samples from patients with neuroblastoma.
Genetic: protein expression analysis
Genetic: western blotting
Other: laboratory biomarker analysis
|Study Design:||Observational Model: Case-Only
Time Perspective: Retrospective
|Official Title:||Analysis of Intersectin Expression in Primary Human Neuroblastomas|
- ITSN1 is highly expressed in neuroblastoma tumors and plays an important role in the development/progression of these tumors [ Designated as safety issue: No ]
|Study Start Date:||July 2011|
|Estimated Primary Completion Date:||January 2100 (Final data collection date for primary outcome measure)|
- To determine whether intersectin (ITSN1) proteins are present at elevated levels in primary human tumor samples.
OUTLINE: Archived tumor tissue samples are analyzed for intersectin (ITSN1) expression by western blot assays with enhanced chemiluminescence and exposed to X-ray film. The films are scanned, and levels of ITSN1 signal are quantified by densitometry.
