Chitinase-3-Like Protein 1 (CHI3L1): A Multifaceted Biomarker in Inflammation, Cancer, and Tissue Remodeling

Endocrinology Diagnostics

CHI3L1 Summary:

Molecular Characteristics:

  • Glycoprotein in chitinase-like protein family
  • Lacks enzymatic activity
  • Conserved (β/α) 8 barrel structure
  • Regulated by inflammatory mediators

Cellular Functions:

  • Cell signaling receptor interaction
  • Triggers MAP kinase, PI3K/AKT pathways
  • Supports cell survival and movement
  • Regulates matrix production
  • Influences collagen formation

Inflammatory Roles:

  • Immune response regulation
  • Macrophage development control
  • Increases in conditions like:
    • Arthritis
    • Inflammatory bowel disease
    • Asthma
  • Tissue repair and healing promotion

Cancer Biology Involvement:

  • Elevated in multiple cancer types
  • Promotes tumor angiogenesis
  • Supports cancer cell invasion
  • Facilitates metastasis
  • Influences epithelial-mesenchymal transition

Key Signaling Pathways:

  • Activated by IL-6, IL-1β, TNF-α
  • Engages NF-κB and STAT3 pathways

Potential Therapeutic Target:

  • Promising for inflammatory disorder treatments
  • Potential cancer intervention strategy
