Adipo-myokine Irisin, a Promising Antioxidant against Nicotine Induced Oxidative Stress in BALB/c mice
Objectives: To determine the role of r-irisin in attenuating nicotine-induced oxidative stress by estimating serum oxidative stress markers and antioxidant enzymes in BALB/c mice.
Method: This 18 month experimental study was carried out at Foundation University Islamabad and National Institute of Health starting in 2020. Thirty healthy BALB/c mice were divided into three groups. Group-I (control group) received normal saline 1ml/kg body weight intra-peritoneally daily for 28 days. Experimental group, Group-II received nicotine 2mg/kg body weight intra-peritoneally, for 28 days to induce oxidative stress. Experimental Group-III was given r-irisin 0.5 μg/g body weight/day via tail vein injection, for the last 14 days in addition to intraperitoneal nicotine for 28 days. On 29th day, intra-cardiac blood samples were taken for estimation of serum antioxidant enzymes [Superoxide dismutase (SOD), Reduced Glutathione (GSH) and Catalases (CAT)], and Thiobarbituric Acid-Reactive Substances (TBARS) levels as lipid peroxidation marker using ELISA. SPSS version 24 was used for statistical analysis. Significant difference in parameters across groups was calculated using one way ANOVA. P-value of < 0.05 was considered significant.
Results: Group-II showed statistically significant increase in serum lipid peroxidation marker (TBARS) levels (p<0.001) and reduction in serum anti-oxidative enzymes (SOD, CAT, GSH) levels (p< 0.001) as compared to Group-I. In Group-III, with co administration of r-irisin, significant improvement in antioxidant enzymes levels and reduction in TBARS levels was observed (p< 0.001) as compared to Group-II.
Conclusion: Irisin ameliorates nicotine induced oxidative stress by improving serum anti-oxidant enzyme levels and reducing serum lipid peroxidation marker.
