RAD51, a protein central to DNA repair, was found to have a novel role in suppressing innate immune signaling. Gene expression analysis was performed on wild-type and RAD51-knockdown human HT1080 cells before and after exposure to 1 Gy of high linear energy transfer iron particle radiation. This dataset originates from the National Aeronautics and Space Administration and was last updated on March 13, 2026.
Use Cases
- Identify gene expression changes linked to replication stress based on the described radiation treatment.
- Analyze the role of RAD51 in immune suppression based on the described STING-mediated pathway.
- Model connections between DNA repair and innate immunity based on the described cytoplasmic self-DNA accumulation.
- Compare transcriptional responses in wild-type versus knockdown cell lines as described in the experimental design.
Strengths
- Data is associated with a novel biological finding connecting DNA repair to immune response.
- Experimental design includes a controlled comparison of wild-type and knockdown cells under radiation stress.
- Dataset originates from the authoritative National Aeronautics and Space Administration.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The dataset is provided in HTML format, which may not be optimal for direct analysis.
