C. elegans Gene Expression Under Space Radiation and Microgravity

NASA used microarray technology to investigate genome-wide expression changes in the C. elegans CC1 strain. The dataset includes three technical replicates of wild-type worms exposed to space radiation, analyzed alongside ground control samples. The data was last updated on March 13, 2026.

Use Cases

• Identify differentially expressed genes based on exposure to space radiation.
• Compare gene expression profiles between space-exposed and ground control samples.
• Analyze the biological impact of microgravity on a model organism's genome.
• Validate microarray analysis techniques for space biology applications.

Strengths

• Data originates from NASA, a recognized authority in space research.
• Includes controlled experimental design with ground control samples.
• Uses technical replicates, which may improve measurement reliability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a BIN format, which may require specialized tools for access.
