Extreme skeletal myocyte aging associated with a 12.7-fold higher likelihood of developing amyotrophic lateral sclerosis.
Cell-specific aging signatures correlated with future cancer and chronic diseases.
Patients with extreme aging across more than 20 cell types had approximately 34% survival over 15 years.
Youthful immune and neuronal aging signatures associated with more favorable survival outcomes.

Guideline-Based Recommendations

Diagnosis

Utilize plasma proteomic data to estimate biological age of cell types.

Management

Consider cellular aging signatures for risk stratification in age-related diseases.

Monitoring & Follow-up

Assess plasma proteomic profiles for ongoing evaluation of cellular aging.

Risks

Extreme cellular aging correlates with increased risk of neurodegenerative diseases, cancer, and chronic conditions.

Patient & Prescribing Data

Predominantly older and White cohorts.

Noninvasive assessment of cell type-specific biological aging may identify patients at elevated risk.

Clinical Best Practices

Incorporate proteomic profiling in routine assessments for aging-related disease risk.
Monitor cellular aging across multiple cell types for comprehensive risk evaluation.
