Abstract:
Activity-dependent neuroprotective protein (ADNP), a crucial brain development factor, contains a unique sequence, termed NAPVSIPQ, which protects mice against closed head injury (CHI). The aim of this study was to determine whether CHI affects ADNP mRNA expression in the injured brain hemisphere. Male C57JBL/6J mice were subjected to CHI. Brains were removed 5 h, 24 h, 7 d, and 29 d post-CHI. A comparison was made between ADNP mRNA in the injured versus the noninjured hemisphere using real-time polymerase chain reaction. A nonsignificant change (p >0.05) was found 5 h, 24 h, and 7 d post-CHI. However, a significant increase (p <0.05) in ADNP mRNA expression was detected in the injured cerebral hemisphere 29 d post-CHI. The data presented may be associated with ADNP's crucial involvement in brain development and response to injury.
