[Retracted] Potential Progression Mechanism and Key Genes in Early Stage of mTBI

Figure 4

Comparison of SPP1 mRNA levels in the frontal cortex of rats. (a)–(c) Identification of the SPP1 gene identified 24 hours post mTBI. (a) Validation of the changes in the SPP1 mRNA expression level between the sham and smTBI groups. (b) Validation of the changes in the SPP1 mRNA expression level between the sham and rmTBI groups. (c) Validation of the changes in the SPP1 mRNA expression level between the smTBI and rmTBI groups. (d)–(f) Identification of the SPP1 gene 14 days after mTBI. (d) Validation of the changes in the SPP1 mRNA expression level between the sham and smTBI groups. (e) Validation of the changes in the SPP1 mRNA expression level between the sham and rmTBI groups. (f) Validation of the changes in the SPP1 mRNA expression level between the smTBI and rmTBI groups. The data are presented as the means ± SDs, and was considered to indicate significance. smTBI: single mild traumatic brain injury; rmTBI: repetitive mild traumatic brain injury.
