To determine the effect of the consumption of (1.5 g/day) for six months on oxidative stress (OxS) and inflammation markers and its association with telomere length (TL) in older adults with metabolic syndrome (MetS).
The study was conducted in a sample of 48 older adults: placebo (EP) and experimental (EG) groups. Lipoperoxides, protein carbonylation, 8-OHdG, total oxidant status (TOS), SOD, GPx, HO inhibition, total antioxidant status (TAS), inflammatory cytokines (IL6, IL10, TNF-α), and TL were measured before and six months post-treatment.
We found a significant decrease in the levels of lipoperoxides, protein carbonylation, 8-OHdG, TOS in the EG in comparison PG. Likewise, a significante increase of TAS, IL-6, and IL-10 levels was found at six months post-treatment in EG in comparison with PG. TL showed a statistically significant decrease in PG compared to post-treatment EG.
Our findigns showed that the supplementation of has antioxidant, and anti-inflammatory effects, and diminushion of shortening of telomeric DNA in older adults with MetS. This would be the first study that shows that the intervention with has a possible geroprotective effect by preventing telomeres from shortening as usually happens in these patients. Therefore, suggesting a protection of telomeric DNA and genomic DNA.
确定连续六个月每天摄入 (1.5 克)对代谢综合征(MetS)老年患者氧化应激(OxS)和炎症标志物的影响及其与端粒长度(TL)的关系。
本研究在 48 名老年受试者中进行:安慰剂(EP)和实验组(EG)。在治疗前和治疗后六个月测量脂质过氧化物、蛋白质羰基化、8-OHdG、总氧化状态(TOS)、SOD、GPx、HO 抑制、总抗氧化状态(TAS)、炎性细胞因子(IL6、IL10、TNF-α)和 TL。
我们发现 EG 组的脂质过氧化物、蛋白质羰基化、8-OHdG、TOS 水平显著降低,而 PG 组则相反。同样,EG 组在治疗后六个月的 TAS、IL-6 和 IL-10 水平显著升高,而 PG 组则相反。TL 显示 PG 组与治疗后 EG 组相比有统计学意义的下降。
我们的研究结果表明, 补充具有抗氧化和抗炎作用,并能减少 MetS 老年患者端粒 DNA 的缩短。这将是第一项表明干预 具有潜在的保护作用,可防止端粒缩短,如这些患者通常发生的那样。因此,提示保护端粒 DNA 和基因组 DNA。
