Activity/exercise-induced changes in the liver transcriptome after chronic spinal cord injury

Area of Science:

• Neuroscience
• Physiology
• Genomics

Background:

• Spinal cord injury (SCI) leads to multi-organ dysfunction by disrupting peripheral organ innervation.
• The liver's innervation includes sympathetic, parasympathetic, and sensory axons from dorsal root ganglion (DRG) neurons, crucial for bi-directional signaling.
• SCI-induced liver inflammation may precede and worsen spinal cord pathology, potentially influenced by physical activity and exercise.

Purpose of the Study:

• To investigate the impact of activity and exercise on gene expression patterns in the liver of rats with chronic SCI.
• To identify genes associated with liver pathologies in the context of SCI.
• To provide high-quality RNA sequencing data for further exploration of SCI-related liver changes.

Main Methods:

• RNA sequencing of liver tissue from rats with chronic spinal cord injury.
• Analysis of comprehensive gene expression data.
• Alignment of sequenced data to the Rn6 genome for quality assessment.

Main Results:

• High-quality RNA sequencing data with high alignment rates to the Rn6 genome were obtained.
• Gene expression patterns indicative of known liver pathologies were identified.
• Data facilitates exploration of SCI effects on liver gene expression.

Conclusions:

• Gene expression analysis provides insights into SCI-induced liver changes.
• Activity and exercise may play a role in modulating SCI-related liver inflammation.
• The generated dataset serves as a valuable resource for understanding SCI pathophysiology.
