Integrating network pharmacology and animal experimental validation to investigate the mechanism of lotus leaf in obesity
Abstract
BACKGROUND
Lotus leaf and its extracts have been reported to exert various beneficial effects; however, their anti-obesity mechanisms remain relatively unclear. Therefore, we investigated the mechanism by which lotus leaf regulates obesity using network pharmacology, molecular docking, and animal experimentation.
METHODS
Network pharmacology was used to identify potential targets and pathways through which lotus leaf regulates obesity. Molecular docking technology was used to verify the interaction between lotus leaves and core targets of obesity. Additionally, a rat model of obesity induced using a high-fat diet was established to examine the anti-obesity effects of lotus leaf. Moreover, western blotting was performed to examine the expression levels of the target proteins and elucidate the molecular mechanisms of lotus leaf.
RESULTS
Quercetin, nuciferin, catechin, kaempferol, and isorhamnetin were identified as the main active compounds in the lotus leaves involved in obesity treatment. Network pharmacology analysis identified fibroblast growth factor (FGF) 15 and farnesoid X receptor (FXR) as core targets of lotus leaf, and the AGE-RAGE signaling pathway in diabetic complications, neuroactive ligand-receptor interactions, insulin resistance, and cancer pathways, as biomechanistic pathways by which lotus leaf ameliorates obesity. Additionally, molecular docking analysis indicated a strong binding affinity between the main active ingredients of lotus leaf and the core…
