The composition and properties of collagen in teleost (bony fish) cartilage have never been studied. In this study, we aimed to identify and characterise all collagen species in the nasal cartilage of hoki (Macruronus novaezelandiae). Four native collagen species were extracted using two techniques, and isolated with differential salt precipitation. We were able to assign the identity of three of these collagen species on the basis of solubility, SDS-PAGE and amino acid analyses. We found that hoki cartilage contains the major collagen, type II, and the minor collagens, type IX and type XI, which are homologous to those found in mammal and chicken cartilage. Using these extraction protocols, we also isolated a full-length type IX collagen from cartilage for the first time. In addition, we detected a 90 kDa, highly glycosylated collagen that has not been identified in any other species. For each isolate, structural and biochemical characterisations were performed using circular dichroism and Fourier transform infrared spectroscopy analyses, and the thermal denaturation properties were determined. Our results showed that the properties of hoki cartilage-derived collagens are similar to those of collagens in mammalian cartilage, indicating that teleost cartilage could provide biological ingredients for the development of biomaterials to treat cartilage-related illnesses.

Introduction: One of the chronic progressive diseases of the elderly is Osteoarthritis. There is a wide spectrum of Nutraceuticals, for Osteoarthritis, but there does not exist, a convincing literature based evidence, in support of their denitive and specic rationale of utility. We here in, aim to evaluate the evidence in literature hither to available, for establishing the potency and efcaciousness of the indigenous type II collagen variant. Methods: st st A schematic search was performed of Pub Med, Scopus and the Google Scholar, from dates (1 December 2009 to 1 December 2020), with the search terms: 'Osteoarthritis', 'Nutraceuticals', 'Oral Collagen', 'Glucosamine', 'Chondroitin Sulfate', 'Acetaminophen' and 'Native Collagen'. Articles containing the following were included in the study: Randomized Control Trial and Clinical Trial, Primary data, OA and Oral Collagen studies related to joint disease. Total number of patients studied, the number of patients who were treated by Native Collagen Type II variant, Denatured Collagen Type II variant, Glucosamine, Chondroitin Sulfate and Acetaminophen.A number of studies using various scoring systems were incorporated in our study. Finally, all the functional outcomes, according to the VAS and WOMAC scores, were cumulatively tabulated, and analyzed schematically and their results deduced. Results: Multiple researches have been executed, to elucidate upon the efcacy and the safety, of Oral Collagen of the type II variant, in the medicaments prescribed for OA, especially relating to the Knee joint. Oral Collagen is administered, either in a Denatured or an Undenatured form .The results indicate , that out of all the Nutraceuticals, Undenatured/Native collagen of the type II variant, proved to be by far the most safe and signicantly more efcacious, compared to other Nutraceuticals. Although all the suggested treatments reduced the WOMAC and the VAS scores, here in UC II, showed more efciency and sustenance of the pain reduction, in both the assessment scores, in comparison with other orally administrated Nutraceuticals. Conclusion: Our Meta-Analysis concludes that, Type II Undenatured Collagen, is a relatively safe and also signicantly more efcient, in improving the joint function, ROM and for the alleviation of bone joint pain, in OA knee (Genu OA) patients.
