RESUMO
BACKGROUND: The prevalence of obesity is increasing in the world, and the Type II diabetes associated with obesity led researchers to seek alternative methods to treat these two chronic diseases. In the case of obesity and diabetes, changes occur in the levels of inflammatory mediators. A study was conducted to investigate the molecular mechanism of the Rheum ribes L. plant regarding obesity and inflammation. METHODS AND RESULTS: Differentiated 3T3-L1 mouse cell lines were used as an experimental model. A dose-response relationship was established to determine at what dose and time of treatment the R. ribes L. plant extract would act effectively. To assess expression on the transcriptional level, q-PCR analyses were performed. The primers to evaluate the expression levels of genes such as Dgat1, Lpl, Fasn, ColV, Il-6, and Mcp1, which are known to be associated with obesity and insulin resistance, inflammation, and cell skeletal restructuring was designed using NCBI sequences. 18S was chosen as the housekeeping gene for normalization. CONCLUSION: It was found that applying 50 µg/mL and 100 µg/mL of R. ribes root extract to 3T3-L1 adipocyte cells for 24 and 48 h resulted in anti- obesity and anti-inflammatory effects on the genes examined at the transcriptional level. It is an effective study to understand the molecular mechanisms by which R. ribes, which is known to have anti-diabetic, anti-obesity and anti- inflammatory activities, and to establish a link between these activities.
