The effect of enriched environment on the outcome of traumatic brain injury; a behavioral, proteomics, and histological study.

De novo hippocampal neurogenesis contributes to functional recovery following traumatic brain injury (TBI). Enriched environment (EEN) can improve the outcome of TBI by positively affecting neurogenesis. Blast induced traumatic brain injury (bTBI) characterized by memory impairment and increased anxiety levels, is a leading cause of chronic disability among soldiers.

Stress and traumatic brain injury: a behavioral, proteomics, and histological study.

Psychological stress and traumatic brain injury (TBI) can both result in lasting neurobehavioral abnormalities. Post-traumatic stress disorder and blast induced TBI (bTBI) have become the most significant health issues in current military conflicts. Importantly, military bTBI virtually never occurs without stress.

Reverse phase protein microarray technology in traumatic brain injury.

Antibody based, high throughput proteomics technology represents an exciting new approach in understanding the pathobiologies of complex disorders such as cancer, stroke and traumatic brain injury. Reverse phase protein microarray (RPPA) can complement the classical methods based on mass spectrometry as a high throughput validation and quantification method. RPPA technology can address problematic issues, such as sample complexity, sensitivity, quantification, reproducibility and throughput, which are currently associated with mass spectrometry-based approaches.

SATB2 interacts with chromatin-remodeling molecules in differentiating cortical neurons.

During our search for developmental regulators of neuronal differentiation, we identified special AT-rich sequence-binding protein (SATB)2 that is specifically expressed in the developing rat neocortex and binds to AT-rich DNA elements. Here we investigated whether the regulatory function of SATB2 involves chromatin remodeling at the AT-rich DNA site. In-vitro and in-vivo assays using a DNA affinity pre-incubation specificity test of recognition and chromatin immunoprecipitation showed that SATB2 specifically binds to histone deacetylase 1 and metastasis-associated protein 2, members of the nucleosome-remodeling and histone deacetylase complex.
