The Relationship Between Serum MG53 Levels and the Presence of Metabolic Syndrome and Its Components.

: MG53 is a myokine/cardiokine involved in membrane repair. Some preclinical studies suggest that it is associated with insulin resistance. Metabolic syndrome (MS) is manifested by dyslipidemia, hypertension (HT), visceral obesity, hyperinsulinism, and glucose intolerance. We aimed to evaluate the relationship between the MG53 protein and MS and its components. : This study was conducted among 64 patients with MS and 64 age- and sex-matched healthy participants. MG53 levels were measured using Human-MG53, a commercially available enzyme-linked immunosorbent assay (ELISA) kit (Cat# CSB-EL024511HU, Alfagen laboratory supplies, Cusabio, Bornova, İzmir.). : There was no significant connection between serum MG53 levels and the presence of MS ( = 0.969). We found no correlation between serum MG53 levels and the presence of HT, weight, waist circumference, body mass index, HDL-C, fasting blood glucose, and HbA1c levels. : This study's results suggest no association between serum MG53 levels and MS parameters in the studied ethnic population. Due to the limited number and controversy of available studies on this subject, our findings may provide perspective for conducting studies with more diverse populations to obtain more comprehensive results.
