Epithelial tumor metastasis is preceded by an accumulation of collagen cross-links that heighten stromal stiffness and stimulate the invasive properties of tumor cells. However, the biochemical nature of collagen cross-links in cancer is still unclear. Here, we postulated that epithelial tumorigenesis is accompanied by changes in the biochemical type of collagen cross-links. Utilizing resected ...
The controlled assembly of collagen monomers into fibrils, with accompanying intermolecular cross-linking by lysyl oxidase-mediated bonds, is vital to the structural and mechanical integrity of connective tissues. This process is influenced by collagen-associated proteins, including small leucine-rich proteins (SLRPs), but the regulatory mechanisms are not well understood. Deficiency in fibromo...
The conversion of the reducible divalent cross-links in collagen to non-reducible multivalent cross-links in mature collagen has resulted in the identification of several new amino acids as the putative mature cross-link. None of these compounds has completely satisfied the necessary criteria. We have now isolated an amino acid of high Mr, derived from lysine, that is only present in high-Mr pe...
Objective: to present corneal collagen corsslinking techniques. Corneal collagen cross-linking (CXL) is a procedure used to slow down or arrest the progression of keratoconus in order to avoid or, at least delay the necessity of keratoplasty. CXL means photopolimerisation of the stromal fibrillar tissue, in order to increase their stiffness and resistance to the corneal ectasia. CXL is a proces...
The management of keratoconus and post – LASIK ectasia included until recently spectacle correction, Hard Fitted Gas Permeable Contact Lenses, Intrastromal Corneal Ring Segments. All these interventions are purely symptomatic and their only aim is the improvement of visual function of patients, without interfering with the pathophysiology of the ectatic disorders. The only actual treatment for ...
Collagen-Based Biomaterials Collagen-based biomaterials (CBBs) have been confirmed to prepare dressings and dermal substitutes, surgical sutures, plasma tissue-engineered scaffolds, etc. Article 2202042 by Xuechuan Wang, Huie Jiang, Xinhua Liu, co-workers, provides—in combination with the situation in China—thorough strides CBBs structures, cross-linking, forming technologies, real-world applic...
