Oxidative stress (OS) has greatly interested the research community in understanding damaging processes occurring cells. OS is triggered by an imbalance between reactive oxygen species (ROS) production and their elimination antioxidant system; however, ROS function as second messengers under physiological conditions. are produced from endogenous exogenous sources. Endogenous sources involve mitochondria, nicotinamide adenine dinucleotide phosphate hydrogen (NADPH), oxidases (NOXs), endoplasmic reticulum (ER), xanthine (XO), endothelial nitric oxide synthase (eNOs), others. In contrast, might be generated through ultraviolet (UV) light, ionizing radiation (IR), contaminants, heavy metals, among It can damage DNA, lipids, proteins if not controlled. To avoid oxidative damage, systems activated. present review, we focus on basic concepts of OS, highlighting nitrogen (RONS) derived internal external last elimination.

Collagen is a force-bearing, hierarchical structural protein important to all connective tissue. In tendon collagen, high load even below macroscopic failure level creates mechanoradicals by homolytic bond scission, similar polymers. The location and type of initial rupture sites critically decide on both the mechanical chemical impact these micro-ruptures tissue, but are yet be explored. We here use scale-bridging simulations supported gel electrophoresis mass spectrometry determine breakage points in collagen. find collagen crosslinks, as opposed backbone, harbor weakest bonds, with one particular trivalent crosslinks most dominant site. identify this sacrificial, rupturing prior other bonds while maintaining material's integrity. Also, collagen's weak funnel ruptures such that potentially harmful readily stabilized. Our results suggest unique mode tailored towards combatting an early onset material ageing.

The extracellular matrix (ECM) provides structural support for tissues and regulatory signals resident cells. ECM requires a careful balance between protein accumulation degradation homeostasis. Disruption of this can lead to pathological processes such as fibrosis in organs across the body. Post-translational crosslinking modifications proteins collagens alter structure function.

Collagen, the most abundant structural protein found in mammals, plays a vital role as constituent of extracellular matrix (ECM) that surrounds cells. Collagen fibrils are strengthened through formation covalent cross-links, which involve complex enzymatic and non-enzymatic reactions. Lysyl oxidase (LOX) is responsible for catalyzing oxidative deamination lysine hydroxylysine residues, resulting production aldehydes, allysine, hydroxyallysine. These intermediates undergo spontaneous condensation reactions, leading to immature initial step development mature cross-links. Additionally, glycation contributes abnormal cross-linking collagen fibrils. During glycation, specific arginine residues modified by reducing sugars, creation Advanced Glycation End-products (AGEs). AGEs have been associated with changes mechanical properties fibers. Interestingly, various studies reported plant polyphenols possess amine oxidase-like activity can act potent inhibitors glycation.
