Epigenetic Regulation in the Brain after Spinal Cord Injury : A Comparative Study

J Korean Neurosurg Soc, 2013 · DOI: http://dx.doi.org/10.3340/jkns.2013.53.6.337 · Published: June 1, 2013

Simple Explanation

This study investigates how the brain changes after a spinal cord injury (SCI) in mice. Specifically, it looks at the levels of certain proteins in the brain that are important for nerve cell development, survival, and death. The researchers measured the amounts of BDNF, GDNF, NGF, and HDAC1 in the brains of mice at different times after SCI. The results showed that BDNF levels increased significantly in the brain two weeks after the injury, suggesting that BDNF may play a role in helping the brain reorganize after SCI.

Study Duration

8 weeks

Participants

60 female imprinting control region mice

Evidence Level

Not specified

Key Findings

1
BDNF expression was significantly elevated in the SCI group compared to the control group at 2 weeks after SCI.
2
NGF and GDNF levels showed a tendency to increase at 2 weeks compared with the control group, but the differences were not statistically significant.
3
HDAC1 levels showed an elevated tendency in the SCI group, but the alteration was not significant.

Research Summary

This study investigated the alterations in the expression of key regulators of neuronal development, survival, and death following SCI in mice. The findings revealed a significant increase in BDNF expression in the brain at 2 weeks post-SCI, suggesting its potential role in brain reorganization. While NGF and GDNF showed an increasing trend and HDAC1 displayed an elevated tendency, these changes were not statistically significant.

Practical Implications

Potential Therapeutic Target

Upregulation of BDNF may be a target for therapies aimed at promoting brain reorganization after SCI.

Further Research

Further studies are needed to explore the roles of NGF, GDNF and HDAC1 in brain changes after SCI.

Understanding Brain Plasticity

The study contributes to understanding the mechanisms of brain plasticity and reorganization following SCI.

Study Limitations

1
The study was conducted on mice, and results may not directly translate to humans.
2
Only a limited number of proteins were investigated.
3
The study focused on the whole brain, and regional changes may not have been detected.
