Rosehip Extract Decreases Reactive Oxygen Species Production and Lipid Accumulation in Hypertrophic 3T3-L1 Adipocytes with the Modulation of Inflammatory State

Background: Rosa canina L. (rosehip) is used worldwide in traditional medicine as a plant with medicinal properties. However, its anti-obesity effects are not fully explained on a transcriptional level. Methods: In the present work, the 3T3-L preadipocytes were utilized to explore the impact of R. canina fruit extract (RCE) on the cellular and molecular pathways involved in adipocyte hypertrophy. Results: Obtained results showed the ability of RCE to reduce lipid overloads in hypertrophic adipocytes associated with the down-regulation of mRNA expressions of adipogenic transcription factors such as PPARγ, C/EBPα, and SREBP-1c as well as genes involved in lipid biosyntheses such as FAS, LPL, and aP2. Moreover, obesity-associated oxidative stress (antioxidant enzyme activities and ROS generation) and inflammation were ameliorated in RCE-treated hypertrophic adipocytes. The mRNA and protein levels of adipokines such as leptin, resistin, and adiponectin were restored to more favorable levels. Conclusions: Rosa canina fruit might be a valuable source of phytochemicals in preventing obesity and obesity-related metabolic complications.
