Brief Summary:

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to brain tumors.

PURPOSE: This research studies gene expression and location in samples from patients with brain tumors.

Condition or disease Intervention/treatment
Brain and Central Nervous System Tumors Genetic: gene expression analysis Genetic: genetic linkage analysis Genetic: microarray analysis Other: immunohistochemistry staining method Other: laboratory biomarker analysis

Detailed Description:


  • To determine the expression and subcellular localization of nei endonuclease VIII-like 3 (NEIL3) in brain tumors.

OUTLINE: Tissue microarray samples are analyzed for NEIL3 expression and subcellular localization by immunohistochemical methods.

Study Type : Observational
Estimated Enrollment : 10 participants
Observational Model: Case-Only
Time Perspective: Retrospective
Official Title: Expression and Subcellular Localization of NEIL3 in Tumors
Study Start Date : April 2012
Actual Primary Completion Date : May 2016

Primary Outcome Measures :
  1. Correlation of NEIL3 expression and/or nuclear localization with tumor type or grade with respect to degree of differentiation
