Deepening in the understanding of the role of collagen subunits on the differential molecular arrangement of P. glauca and M. merluccius marine collagens. Protein Expr Purif 2023; 212:106356.

Abstract
Decades of extensive efforts on marine collagen extraction and characterization allowed to recognize the unique and excellent characteristics of marine collagen offering advantages over that obtained from terrestrial sources. However, not all marine collagens have the same biochemical characteristics; understanding those at molecular and supramolecular level, is crucial for optimal design of applications. One relevant aspect of collagen characterization is the analysis of its different subunits (α-chains) and their intermolecular cross-links (β- and γ-components), which ultimately determine the specific functions of a particular collagen. Collagens from a teleost and an elasmobranch species were analyzed to understand the influence of their subunit composition and intermolecular crosslinking pattern on their different physicochemical behaviour. For comparative purposes a commercial mammal collagen was included in the study. Although electrophoretic profiles showed the typical composition of type I collagen for hake, blue shark and calf collagen, molar ratios of their α-chains were different indicating a different degree of dimerization of their α2-chains with implications in the presence of a different crosslinking degree pattern. Electrophoresis, amino acid composition, hydrophobicity (RP-HPLC) and molecular weight analysis (GPC-HPLC) results, besides a peptide mapping and an antioxidant activity study of the resultant peptides, would help to understand the role of different subunit collagen composition and different crosslinking pattern in the conformation of a differential quaternary supramolecular structure within different species and its biofunctional implications. The experiments developed would allow to progress in the valorization potential of fish discards and byproducts to explore commercial uses of collagens from marine origin.

Abstract
Rats were intratracheally instilled with bleomycin or with silica (quartz) dust to induce lung fibrosis. Several weeks later, purified collagen chains (or collagen digests) were isolated from the lungs of these animals and from age-matched controls instilled intratracheally with saline solution, and the ratios of hydroxylysine to lysine and of the dysfunctional cross-links DHLNL to HLNL were quantified. Collagen from fibrotic lungs had significantly higher ratios of DHLNL:HLNL than did control lungs, 15.5 +/- 4.8 and 17.1 +/- 4.8 vs. 2.3 +/- 0.5 for the silica-instilled and the bleomycin-instilled animals, respectively. The hydroxylysine:lysine ratio was significantly increased for the alpha 1(I) chain, to a value 170% of that of lung collagen from control animals, and for several of its constituent CNBr peptides. Lung tissue was exhaustively digested with collagenase and specific cross-linked peptides were isolated and characterized. The cross-linked alpha 1(I) x alpha 1(I) peptide linked by the residues 87 x 16C, with a ratio of DHLNL:HLNL of 17:1, demonstrated that the increased hydroxylation of the dysfunctional cross-links in fibrotic lung collagen could be accounted for in part by increased hydroxylation of the lysine residue at position 16C of the C-terminal telopeptide of the collagen alpha 1(I) chain. It proved impossible to locate the corresponding N-terminal cross-linked fragment from alpha 1(I) x alpha 1(I) chains, 9N x 930, possibly due to further reactions of this material to form the material referred to as poly(CB6). Isolated poly (CB6) accounted for more than half of the total alpha 1(I)CB6 peptide expected in lung collagen, and had a hydroxylysine:lysine content 2.8 times greater in bleomycin-treated animals than in their age-matched controls. Evidence was also found for a cross-linked alpha 1(III) x alpha 1(I) peptide linking residue 87 from the alpha 1(III) chain with residue 16C from the alpha 1(I) chain; it also had an increased ratio of DHLNL:HLNL. We conclude that the increased hydroxylation of lysine observed in two different animal models of lung fibrosis occurs preferentially at the N- and C-terminal nonhelical extension peptides of the alpha 1(I) collagen chains, and that this apparent specificity of overhydroxylation of fibrotic collagen may have important structural and pathological consequences.

Abstract
Chondrocyte-laden collagen scaffolds were evaluated in extensive cartilage defects in an equine model. Arthroscopic techniques were used to implant a chondrocyte-collagen culture product in 15-mm defects in the lateral trochlear ridge of the femoropatellar joint of 12 horses. Ungrafted control defects were formed in the opposite joint. Groups of six horses were terminated at 4 and 8 months after implantation and the repair sites, adjacent cartilage, and remote cartilage within each femoropatellar joint examined biochemically. Eight months following surgery the relative proportions of type II collagen in grafted and ungrafted defects, determined using the ratio of cyanogen bromide cleavage products alpha 1(II)CB10/alpha 2(I)CB3,5, were not significantly different (31.57 +/- 2.76% and 26.88 +/- 2.76%, respectively). Aggrecan content was significantly improved in grafted defects (85.61 +/- 6.51 and 74.91 +/- 10.31 micrograms/mg dry weight). Cartilage surrounding grafted defects also showed improved maintenance of cartilage glycosaminoglycan content. Thus, chondrocyte grafting in collagen scaffold vehicles improved the aggrecan content in extensive cartilage defects and surrounding normal cartilage. However, given the continued disparity between repair tissue and normal cartilage aggrecan content, and the low proportion of type II collagen in grafted defects, the utility of collagen scaffolds for chondrocyte grafting of large cartilage defects seems limited.

Abstract
Collagenous peptides containing the Ehrlich chromogen (EC) were selectively isolated from a tryptic digest of bovine tendon by coupling to a diazotized polyacrylamide support. The isolated p-phenol-azo-EC peptides were purified and characterized by amino acid and sequence analyses. EC occurred in stoichiometric amounts in trimeric cross-linked chains originating from the known cross-link regions of type-I collagen. The major locus of the EC was alpha 2(I)Hyl-933 x alpha 1(I)Lys(Hyl)-9N x alpha 2(I)Lys(Hyl)-5N but it was also shown to occur at the loci alpha 1(I)Hyl-87 x alpha 1(I)Lys(Hyl)-16C x alpha 1(I)Lys(Hyl)-16C and alpha 1(I)Hyl-930 x alpha 1(I)Lys(Hyl)-9N x alpha 2(I)Lys(Hyl)-5N. After sequence analyses of the C-terminal helical cross-link region alpha 2(I)928-963, corrections are presented for residues 927, 930, 932 and 933 of the bovine alpha 2(I) chain. The collagen-associated EC is postulated to be a trisubstituted pyrrole formed by the reaction of the aldehyde form of a telopeptidyl lysine residue with a bifunctional keto amino cross-link. It is also proposed that when the telopeptidyl lysine residue is hydroxylated the above reaction will result in pyridinoline formation.

Abstract
Dentinogenesis offers a unique system for the study of changes in collagen structure occurring simultaneously with mineralization. Bovine dentin was found to contain about one reducible crosslink per collagen molecule; rat dentin contained twice this amount. In contrast, bovine dentin contained twice as much pyridinium crosslink as did rat dentin collagen. These results indicate that the collagen in rat teeth is less mature and again emphasize the difference in composition between the organic matrices of rat and bovine dentin. In dissected bovine predentin, the unmineralized precursor of dentin, the content of reducible crosslinks was almost double that of dentin. Only minute amounts of non-reducible crosslinks were found in predentin, whereas both pyridinoline and deoxy-pyridinoline were present in collagen from mineralized dentin. The observed differences in crosslinking between predentin and dentin of the same teeth may indicate some alterations within the area of mineralization.

Abstract
The relative proportions of pyridinoline and deoxypyridinoline in bone showed large species variations, although the total number of pyridinium crosslinks in rat, rabbit and bovine bone collagen was only 25-30% of that found in articular cartilage. Three pyridinium-containing peptides were isolated from cyanogen bromide digests of rat femoral bone and were characterized by their Mr values and amino-acid compositions. The results showed that pyridinoline and its deoxy analogue were equally distributed at two locations stabilizing the 4D stagger through interactions involving both the N- and C-terminal telopeptide regions. Less than stoichiometric amounts of pyridinium crosslinks were present in the peptides, suggesting that the isolated peptides contained additional (unidentified) maturation products of the bifunctional, reducible crosslinks.

Abstract
A trypsin digest of denatured NaB3H4-reduced native bovine periodontal ligament was prepared and fractionated by gel filtration and cellulose ion-exchange column chromatography. Prior to trypsin digestion, a complete acid hydrolysate was subjected to analyses for nonreducible stable and reducible intermolecular cross-links. Minute amounts of the former and significant amounts of the reduced cross-links dihydroxylysinonorleucine (1.1 mol/mol of collagen), hydroxylysinonorleucine (0.9 mol/mol of collagen), and histidinohydroxymerodesmosine (0.6 mol/mol of collagen) were found. The covalent intermolecular cross-linked two-chained peptides that were isolated were subjected to amino acid and sequence analyses. The structures for the different two-chained linked peptides were alpha 1CB4-5(76-90)[Hyl-87] X alpha 1CB6-(993-22c)[Lysald-16c], alpha 1CB4-5(76-90)[Hyl-87] X alpha 1CB6(993-22c)[Hylald-16c], alpha 2CB4(76-90)[Hyl-87] X alpha 1CB6(993-22c)[Lysald-16c], and alpha 2CB4(76-90)[Hyl-87] X alpha 1CB6(993-22c)[Hylald-16c]. The cross-link in each peptide was glycosylated. This is the first characterization by sequence analysis of a cross-link involving Hyl-87 in an alpha 2 chain in collagen. A stoichiometric conversion of residue 16c aldehyde to an intermolecular cross-link in each of the COOH-terminal nonhelical peptide regions of both alpha 1 chains in a molecule of type I collagen was found. The ratio of alpha 1 to alpha 2 intermolecularly cross-linked chains involved was 3.3:1, indicating a stereospecific three-dimensional molecular packing of type I collagen molecules in bovine periodontal ligament.

Abstract
This collagen was partially dissolved when suspended in solutions containing water-extractable components from bis-GMA-based resins (WECR) for 120 h at 37 degrees C. The WECR may cause changes in collagen conformation; similar effects may occur in dentine collagen exposed to the resins during restoration.

Abstract
Antisera from rabbits immunized against bovine Type I collagen were used to develop a specific radio-immunoassay for the antigenic determinant located within the extra-helical carboxy-terminal sequence of the alpha 1 chain. This assay was applied to mixtures of cyanogen bromide peptides of bovine dentine collagen fractionated by (a) gel chromatography on agarose and (b) preparative gel electrophoresis in the presence of sodium dodecylsulfate. The data confirm previous estimates that only about 25% of the total alpha 1CB6 (the cyanogen bromide peptide containing the antigenic determinant) could be isolated in a free uncross-linked state. Antigenically active cross-linked alpha 1CB6 was recovered in three fractions from preparative gel electrophoresis. Two of these (apparent Mr 21,000 and 48,000) contain alpha 1CB6 linked through its carboxy-terminal extra-helical sequence and appear to result from the same, now well-established, 4 D intermolecular relationship within the collagen fibrils. Considered together, these fractions were recovered in amounts which reflect the occurrence of cross-links in these locations at a frequency of close to one for each collagen molecule. About 30% of the total cross-linked alpha 1CB6 was recovered in high molecular weight material barely penetrating the electrophoresis gel. This may be a mixture of products of the further reaction of the initially-formed double-chain cross-linked peptides involving alpha 1CB6 and perhaps also of incompletely cleaved sequences of alpha 1 or alpha 2 chain linked to alpha 1CB6. The absence of a fraction corresponding to a dimer of alpha 1CB6, as reported for bovine corneal and scleral collagens, suggests tissue specificity in the location of intermolecular crosslinks.
