Sample Aging rats
Peptide(s) Studied Cartalax

Key Findings

  • Peptide regulators including Cartalax (Ala-Glu-Asp) improved structural and functional status of bone tissue in aging rats
  • Cartalax treatment was associated with increased bone mineral density compared to age-matched controls
  • The cartilage/bone-derived peptide showed tissue-preferential effects on musculoskeletal structures
  • Results were consistent with the Khavinson model of tissue-specific peptide bioregulation of aging

Study Design

Animal study in aging rats treated with peptide bioregulators. Bone tissue was assessed for structural parameters and mineral density using histomorphometric and densitometric analysis.

Limitations

  • Published in Russian-language journal (English abstract only)
  • Small sample size
  • No detailed dose-response data
  • All authors from the Khavinson group
  • No independent replication
  • Bone mineral density assessment methods not specified in detail

Clinical Relevance

Preclinical evidence suggesting Cartalax may have osteoprotective properties in aging. However, the evidence is very preliminary and no clinical studies exist for Cartalax in osteoarthritis or osteoporosis.

Methodological Note: This study originates from the Khavinson bioregulation group. Independent replication by Western laboratories is lacking.
