| Channa striatus is a carnivorous freshwater fish that is commonly consumed among Malaysians. The fish is known to contain compound(s) that can accelerate the wound healing process in humans, but the attributes of these compound(s) are yet to be clarified. In the current study, we have performed a thorough proteomic profiling of spray -dried and freeze-dried C. striatus water extracts using high-sensitivity liquid chromatography tandem mass spectrometry. Other than the analysis of whole sample, both samples were also fractionated in order to maximise protein detection. About 137 and 194 proteins were identified in spray dried and freeze dried samples, respectively. Actin, myosin, tropomyosin, calcium ion-related protein and collagen are among the proteins that have been identified, and which are suspected to be involved in the wound healing process. A high number of uncharacterised proteins were also detected, which suggested that there are still many fish proteins with unknown functions in C. striatus. In the future, the identified proteins can be isolated and further studies are required for a better understanding on the wound healing property of C. striatus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
