Background: An approach designed to characterize BDNF gene deletion within microglia of the dorsal horn of the spinal cord does not currently exist. Therefore, my goal was to develop methods to assess Cre- mediated BDNF deletion. To this end I designed and tested two different approaches focusing on the aspects of BDNF mRNA expression or genomic level gene deletion. Methods: Approach 1: BDNF messenger RNA was detected by in situ hybridization. Approach 2: BDNF gene deletion was detected by a positive signal semi-quantitative Polymerase Chain Reaction (PCR). Results: In situ hybridization detected spinal BDNF and regional changes in BDNF mRNA following PNI in wild-type mice. The BDNF PCR detected Cre-mediated BDNF deletions in transgenic animals. Conclusion: Two approaches have been developed and initial tests of these approaches show promising results and will provide valuable tools for researchers investigating BDNF deletion in transgenic animals.
