Correlation of the differential expressions of RANK, RANKL, and OPG with obesity in the elderly population in Xinjiang.
Objective: Obesity has been recognized as a global epidemic and public health crisis. The prevalence of obesity has tripled since 1975, especially in the elderly population. Accumulating preclinical and clinical studies have confirmed that chronic low-grade inflammation of adipose tissues is mechanistically related to metabolic diseases and tissue complications in overweight and obesity patients, as a result of the intricate interplay of various pro-inflammatory and anti-inflammatory signaling cascades. The present study aims to explore the differential expressions of receptor activator of nuclear factor-kappa B (RANK), RANK ligand (RANKL), and osteoprotegerin (OPG) in leukocytes of elderly obesity patients in Xinjiang, thereby providing new physiological, cellular, and molecular targets for the treatment of obesity.
Methods: A total of 40 obesity patients and 40 non-obesity patients were selected. The protein and gene expression levels of RANK, RANKL, and OPG in peripheral blood were detected by western blotting and real-time quantitative PCR.
Results: There was no significant difference in the expression levels of RANK protein, OPG protein, and OPG gene between the obesity group and non-obesity group (P > 0.05). The relative expression levels of the RANK gene and RANKL protein and gene were significantly different between the obesity group and non-obesity group (P < 0.05). The differential expressions of the RANK gene, RANKL protein and gene, and the OPG protein in leukocytes had a significant correlation with obesity in the elderly population (P < 0.05).
Conclusion: The expressions of the RANKL protein and gene and RANK gene in leukocytes of elderly obesity patients in Xinjiang were higher than those of non-obesity patients. In the elderly obesity patients in Xinjiang, the abdominal circumference was correlated with the expressions of the RANK gene, RANKL protein and gene, and OPG protein in leukocytes.
