“…30,31 However, ROS formed by phagocytes during respiratory burst seem to have an important physiological function in the immune system. 32 It was experimentally shown that high formation of ROS may result in increased damage to joint cartilage and activation of osteoclast. 33,34 Additionally, ROS destroy the structure of synovial fluid and depolymerize hyaluronic acid, which results in viscosity loss in the joint.…”

“…There is good evidence that oxidative stress causes mitochondrial dysfunction and lowered levels of ATP. 36,37 Thus, the increased levels of ROS/RNS observed in ATL2ABR cells might be responsible for the depleted levels of ATP observed here. Alternatively, the hyperactivation of PARP-1 in ATL2ABR cells, which appears to be due to increased levels of ROS/RNS, would be expected to consume both NAD and ATP resulting in reduced amounts of both.…”

“…В физиологических условиях H 2 O 2 в цитоплазме может производить ограниченный по величине и строго локальный сдвиг редокс-статус клетки путём воздействия на тиоловые группы редокс-чувствительных белков и тем самым участвовать в регулировании клеточного редокс-статуса, что необходимо для сохранения клеточного гомеостаза [43]. Эти факты находятся в соответствии с современной концепцией биологии редокс-систем, согласно которой редокс-сигнализация осуществляется в условиях ниже того порога локальной концентрации H 2 O 2 (не превышающего 1 мкМ), за пределами которого развивается окислительный стресс [60][61][62]. Даже в норме скорость продукции H 2 O 2 митохондриями выше при окислении НЭЖК, чем углеводов [63,64].…”
