8. What Is The Significance Of Downregulated Collagen Genes In Golden-Finned Albino Channa Argus?

The downregulation of collagen genes in golden-finned albino Channa argus is significant because it may be linked to their unique wound healing properties. Although collagen genes are downregulated, they may enrich collagen in areas exhibiting diverse gene expression patterns, necessitating further comprehensive studies.

Potential Link to Wound Healing

A recent study reported that albino golden snakehead fish possesses five causative genes associated with albinism, namely TYR (tyrosinase), SOX10 (SRY-box transcription factor 10), S-100 (S100 calcium-binding protein A1), and NLRC3 (NLR family CARD domain containing 3), which are significantly downregulated in golden albino C. argus.

Influence of S100 Proteins

The receptor for advanced glycation end products (RAGE) shares its receptors with the S100 family proteins, collagen (type I and IV) and several other ligands. S100A11 signaling via RAGE activates p38 MAPK kinase, thereby enhancing the synthesis of human collagen X. In the present study on albino snakeheads, the downregulation of COL10A1 may be linked to S100 proteins, leading to reduced expression of collagen genes, necessitating further investigation for confirmation.

Further Comprehensive Studies

Although we discovered that collagen-related genes are downregulated in golden albino C. argus, they may enrich collagen in areas exhibiting diverse gene expression patterns, necessitating further comprehensive studies. Sveen et al. similarly noted distinct collagen-related gene expression in the caudal fins of Atlantic salmon (Salmo salar L.).
