Stickleback Gene Expression Responses to Parasite Exposure, Three Populations

Transcriptomic data from lab-reared threespine stickleback fish from three populations with varying susceptibility to the cestode parasite Schistocephalus solidus. The dataset, created by Lauren E. Fuess and last updated in March 2026, compares gene expression changes after exposure to immune stimuli, including alum and cestode protein. It is a small dataset of 17.7 KB, stored in an XLSX file.

Use Cases

• Identify shared and population-specific gene expression patterns based on the described transcriptomic responses to immune stimuli.
• Analyze the role of fibrosis-associated gene regulation in parasite defense based on the description of constitutive expression and downregulation patterns.
• Study the evolutionary co-option of tissue damage response pathways based on the investigation of fibrosis as a defense mechanism.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• Focuses on a specific evolutionary event: freshwater colonization by sticklebacks approximately 12,000 years ago.
• Compares transcriptomic responses across three distinct stickleback populations with varying parasite susceptibility.

Limitations

• Dataset is very small at 17.7 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data may reflect bias inherent to the specific lab-reared populations and experimental stimuli used.
