Effects of laparoscopic sleeve gastrectomy on serum lncRNA levels in obese patients

Abstract

Obesity is a disease associated with excessive fat accumulation in the body, which body mass index (BMI) is ≥30 kg/m. Bariatric surgery technique is one of the most common treatment options for obesity with the advantage of faster weight loss in a short time. lncRNAs play a role in adipogenesis and metabolic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), osteoarthritis, and hypertension, so they are significant targets for therapeutic options. In this study, we aimed to determine lncRNAs and specific parameters that show different expressions in the plasma of patients with obesity. We included fifteen patients with BMI ≥30 kg/m2 before and <30 kg/m2 after laparoscopic sleeve gastrectomy (LSG) in the study. Total RNAs, including lncRNAs and other noncoding RNAs, were isolated from plasma samples of patients, and eight lncRNAs (H19, Neat1, HOTAIR, ANRIL, MALAT1, ATB, SNGH5, UCA1) were quantified by real-time PCR. Gene Ontology, KEGG, and relation of obesity analysis were utilized. Unpaired Student's t-test Pearson correlation analysis was used for statistical analysis. We observed a statistically significant increase in the expression levels of all lncRNAs in the patients with the post-operative BMI change. We have added a new dimension to the biomarker studies related to obesity and the clinical follow-up of patients undergoing LSG surgery. Further studies are required for enlighting the molecular mechanisms.
