Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Correlation of NEIL3 expression and/or nuclear localization with tumor type or grade with respect to degree of differentiation [ Designated as safety issue: No ]

Estimated Enrollment: 10
Study Start Date: April 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Detailed Description:


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