Total RNA samples from trabecular osteoblasts of Pthrp+/+ and -/- mice exposed to simulated 0g or 1g for 6 days. The dataset includes 8 different conditions with 2 replicates each, comparing genotypes, gravity exposure, and treatment with a PTHrP peptide. It was published by the National Aeronautics and Space Administration and last updated on March 5, 2026.
Use Cases
- Analyze gene expression changes related to bone metabolism based on microarray analysis of prolactin, apoptosis, and Wnt-related signaling molecules.
- Compare cellular viability under microgravity based on PTHrP expression levels mentioned in the description.
- Evaluate the efficacy of PTHrP peptide treatment as an anabolic agent to prevent cell death based on the experimental results.
- Investigate overlap in expression changes between genotypes under different gravity conditions based on the reported 88% overlap statistic.
Strengths
- Experimental design includes 8 distinct conditions with 2 replicates each.
- Microarray analysis reveals expression changes in specific gene families such as prolactins, IGF, and Wnt-related signaling molecules.
- Results confirm a specific efficacy of PTHrP treatment, reversing a large proportion of microgravity-induced changes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect bias inherent to the specific mouse model and simulated microgravity experimental setup.
