عنوان مقاله [English]
Osteoarthritis (OA) is the most common disease of joints caused by degradation of articular cartilage and subchondral bone. It is unknown whether different therapy exert differential cellular effects. On the other hand, Since OA may be associated with CVD and decrease Telomeres length. Telomeres protect chromosome ends and Integral for the maintenance of telomeres is the protein complex Shelterin. In this study, the effects of ozone (O3) and aerobic training were considered on Shelterin expression proteins in heart rats with knee OA. In this experimental study, knee OA was induced by surgical method in rats. Fifteen male Wistar rats were randomly divided into three groups: knee OA control group (OA); OA plus exercise group (OAE) and OA plus O3 group (OAO). The aerobic training (treadmill; 16 m/min;50 min/day) started 4 weeks after the surgery, 3 days/week for 8 weeks. Rats in the OAO group received O3 at the concentration of 20μg/ml, once weekly for 3 weeks. 48 hours after the programs, cartilage and heart tissues were isolated and expression of RAP1, TIN2 and TPP1 were considered using Western Blot. In OAE significantly increased the expression of RAP1 compared to the OA and OAO groups. But not difference between OA and OAO groups. In OAE group had significantly higher expression of TIN2 compared to the OAO and OAE, and no difference between OAE and OAO groups. Also, there was no significant difference in the expression of TPP1 and between three groups. Aerobic Exercise improved cardiac Shelterin proteins expression in OA rats, rather than the Ozone therapy groups.
