Research Query

Dogs share human environments yet age ~7x faster — they're the perfect interventional model between mice and humans. Download the HLES baseline survey data. Correlate disease burden with breed-specific lifespan (from their genome-wide data). Key SENS question: do shorter-lived breeds show accelerated accumulation of ALL damage categories simultaneously, or do specific damage types dominate in specific breeds? If Great Danes die of cardiac extracellular crosslink-related disease while Cavalier King Charles Spaniels die of mitochondrial-driven neurodegeneration, that tells us damage compartments are independently rate-limiting — the core SENS prediction

What I Did

I initiated the Dog Aging Project data investigation with two parallel efforts:

Literature Search: I pulled relevant knowledge on the SENS damage classification framework and how it maps to specific repair strategies. This foundational material confirms the seven-category framework (cell loss, senescent cells, mtDNA mutations, nuclear mutations/cancer, intracellular junk, extracellular aggregates, extracellular crosslinks) that we'll use to classify canine diseases.

Data Download Attempt: I attempted to download the HLES baseline survey data from the Dog Aging Project, but the automated download process failed. This is likely due to the data requiring formal access through their Terra platform rather than direct public download.

I also reviewed the Dog Aging Project data portal structure at data.dogagingproject.org, which shows they provide curated summary tables of survey variables, but the full dataset requires application through their data access process.

Current Objective & Next Steps

Current Objective: Download publicly available Dog Aging Project data and gather breed-specific lifespan data plus pathophysiology literature for constructing disease-to-SENS category mappings.

Here's my plan for the next iteration:

Explore DAP summary tables directly: Rather than fighting with automated downloads, I'll analyze the publicly available summary tables at data.dogagingproject.org. These tables show health condition prevalences across the cohort, which should give us breed-specific disease patterns if stratified properly.
Compile breed lifespan and pathophysiology literature: I'll search for canonical median lifespan data across 30-50 breeds (covering the full spectrum from Great Danes to Chihuahuas) and gather pathophysiology literature on major breed-specific diseases. This is critical for accurate SENS category mapping—I need to know whether dilated cardiomyopathy in Great Danes is primarily a cell loss problem versus an extracellular crosslink problem, for instance.

Summary

The first iteration made progress on the conceptual framework by confirming the SENS damage classification system, but hit a roadblock on automated data download from the Dog Aging Project. The next steps will pivot to exploring their publicly accessible summary tables while simultaneously building out the breed lifespan database and disease pathophysiology mappings needed to test whether short-lived breeds show category-specific damage dominance versus parallel acceleration across all damage types.
