Snakehead Fish: Unlocking the Secrets of Natural Wound Healing
"Discover how the proteomic profile of Channa striatus reveals its potential as a natural remedy for tissue repair and recovery."
Our bodies have an incredible ability to heal, but sometimes they need a little extra help. When injuries occur, the body's demand for proteins surges, prompting a breakdown of fat and muscle tissue to fuel the repair process. This is where the nutritional power of fish comes into play, offering a complete protein source packed with essential amino acids.
Interestingly, studies suggest that wounds in fish tend to heal more rapidly than in humans, hinting at a unique connection between fish proteins and tissue regeneration. Among these promising species is Channa striatus, a freshwater snakehead fish, commonly known as 'Haruan' in Malaysia, that has been a traditional remedy for wound healing.
For generations, locals have recommended Channa striatus to patients recovering from surgery or childbirth, believing its meat possesses medicinal properties that accelerate recovery. Now, modern science is beginning to unravel the mysteries behind this age-old practice, with researchers delving into the proteomic profile of Channa striatus to identify the specific biomolecules responsible for its wound-healing prowess.
Decoding the Proteomic Puzzle of Channa Striatus
Recent research has harnessed advanced proteomic techniques to analyze the protein composition of Channa striatus meat, aiming to pinpoint the key players involved in wound healing. By employing high-sensitivity liquid chromatography tandem mass spectrometry and PEAKS Studio 7 software, scientists have identified a wealth of proteins and post-translational modifications (PTMs) that contribute to the fish's therapeutic effects.
- Structural proteins: Essential for muscle tissue formation and wound closure, including actin, myosin, and tropomyosin.
- Enzymes: Facilitate various biochemical reactions involved in tissue repair, with trypsin playing a crucial role in protein digestion and fibrocyte differentiation.
- Calcium-related proteins: Regulate calcium signaling and intracellular trafficking, essential for keratinocyte maturation and wound recovery. Calmodulin and parvalbumin stand out as key proteins in this category.
- Collagen: Provides structural support and promotes cell adhesion, angiogenesis, and tissue remodeling. The abundance of collagen in Channa striatus contributes to its wound-healing properties.
Fish-Protein Peptide Research
In silico proteolysis using BIOPEP-UWM identified pepsin at pH > 2 as the most promising proteinase for releasing a high number of DPP-IV- and ACE-inhibitory peptides from red bigeye flesh protein. Red bigeye fish under 15 cm long are categorized as low-value fish. A separate in silico study identified four anchovy proteins—myosin light chain 1, V(D)J recombination-activating protein, 60 kDa chaperonin, and heat shock protein 90AA1—as potential precursors of ACE- and DPP-IV-inhibitory peptides. These findings concern fish-protein peptide potential and do not establish wound-healing effects of snakehead fish.
Gaps in Wound-Healing Research
A 2026 review notes that, despite progress in understanding the cellular and molecular mechanisms of wound healing, a significant gap remains between that understanding and clinical improvement. Chronic wounds are associated with significant morbidity and mortality, and researchers continue to face challenges in improving their care. Proteomics may help assess healing earlier and clarify how treatments affect proteins in wounds, but the cited chapter describes these as potential benefits. A 2026 study compares wound-healing responses to a clinically used collagen hydrogel and two synthetic biomaterials, highlighting that treatment-specific responses are being investigated.
Comparisons Across Fish and Wound Studies
A study comparing wild and cultured snakehead (*Channa argus*) reported fatty-acid-content ratios of 0.3 to 2.5 relative to the fatty acids in the diet, which the source relates to polyenoic-acid biosynthesis and the fish's growth rate. A separate study of snakehead fish protein concentrate (*Channa striatus*) in kwetiau reported 63.45% water content and 12.95% protein content for the product. In wound research, a 2025 study used mass-spectrometry-based proteomics on human samples to examine aged skin wounds at different healing points. Another 2025 report describes comparing a collagen hydrogel with two synthetic biomaterials in skin wound-healing research.
The Future of Fish-Based Therapies
The discovery of these biomolecules has the potential to revolutionize wound care, opening doors for innovative therapies derived from natural sources. As research progresses, scientists aim to isolate and extract these proteins for use in advanced wound dressings, ointments, and regenerative medicine applications.
Proteases and Wound-Stage Analysis
A survey-based audit collated and analyzed 183 responses from US wound specialists about their perceptions of proteases and how they diagnose and manage excessive proteolytic activity. Its source suggests that rebalancing the wound microenvironment and addressing elevated protease activity could help facilitate healing. A 2025 study combined 3D IR-MALDESI mass-spectrometry imaging for lipidomic analysis with bottom-up proteomics by LC–MS to examine different stages of wound healing. The study used lipid distribution and protein identification to investigate molecules potentially involved in healing.
While further studies are needed to fully elucidate the wound-healing pathway, the evidence suggests that Channa striatus may offer a promising avenue for accelerating tissue repair and improving patient outcomes. Its rich protein content, coupled with beneficial post-translational modifications, makes it a valuable candidate for future exploration.
In a world increasingly focused on natural and sustainable healthcare solutions, Channa striatus stands out as a testament to the healing power of nature. With continued research and development, this humble snakehead fish could pave the way for a new era of effective and accessible wound care.
