SOX Genes in Spinal Cord Injury: Redefining Neural Stem Cell Regeneration Strategies

The study design is literature review. The sex-determining region Y gene (SRY)-related high mobility group box (HMG)-box (SOX) gene family has primarily been associated with neural development and sex determination and is a key component of human embryonic development. Recent studies on zebrafish models have demonstrated that the unique ability of the latter for central nervous tissue (CNS) repair following injury is largely mediated by SOX genes. Given that efforts aimed at the structural regeneration and functional restoration of neural tissue still represent a major therapeutic challenge in patients suffering CNS injury, these findings have initiated a discussion regarding the development of novel therapeutic strategies for SCI focusing on neural tissue regeneration. Spinal cord injury (SCI), in particular, represents a field that could greatly benefit from studies related to the function of the SOX genes. Neuro-informatics Laboratory, Mayo Clinic, Rochester, MN. A literature review was conducted, with a focus on SOX gene that has been described in the experimental studies of SCI. In this review, the existing evidence linking the SOX gene family to the pathophysiology of SCI is summarized, and future research steps regarding the potential implications of the SOX genes in neurological recovery following SCI are discussed, especially focusing on highlighting potential therapeutic targets. The potential implications of the latter could play a crucial role in future efforts to advance the treatment approaches to SCI.
