Gypenosides and capsaicinoids in combination ameliorates high-fat-diet- induced rat hyperlipidemia via the PPARγ-LXRα-ABCA1/ABCG1 pathway
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic hepatic disease characterized by excessive fat accumulation, and is the major risk for cardiovascular and metabolic disorders. We explored the therapeutic effect of gypenosides (Gyps) in combination with capsaicinoids (Caps) against high-fat-diet (HFD)-induced rat hyperlipidemia and oxidized low-density lipoprotein (ox-LDL)-treated Raw264.7 cells. Network pharmacology analysis predicted that the potential molecular mechanism of Gyps/Caps combination against hyperlipidemia was mainly associated with steroid metabolism, lipid synthesis and inflammatory response. Animal experiment demonstrated that Gyps/Caps combination lowered the liver weight, liver index, serum lipid profile and hepatic cholesterol content, improved liver function by reducing the serum markers of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), thereby relieving the hepatic injury. Moreover, Gyps/Caps combination inhibited oxidative stress by decreasing the lactic dehydrogenase (LDH) activity and increasing the superoxide dismutase (SOD) activity. Western blotting result suggested that Gyps/Caps combination could upregulate the expressions of peroxisome proliferator-activated receptors γ (PPARγ), liver X receptor α (LXRα), ATP-binding cassette transporter A1 (ABCA1) and ATP-binding cassette transporter G1 (ABCG1) in the liver tissue. Cellular experiment revealed that the combination treatment protected RAW264.7 cells from ox-LDL induction through inhibiting apoptosis, lipid-decreasing and anti-inflammation, and caused the dramatic enhancement on PPARγ expression. Notably, the combined use of Gyps and Caps did not influence the pharmacological outcomes of each other, but significantly enhanced the overall therapeutic effect in ameliorating HFD-induced hyperlipidemia. Our research provided an experimental basis for advanced research and clinical application of Gyps/Caps combination. Importantly, our cumulative data indicated that combination use of Gyps and Caps may be an effective therapeutic strategy for alleviating hyperlipidemia-induced NAFLD.
期刊介绍：
Journal of Functional Foods continues with the same aims and scope, editorial team, submission system and rigorous peer review. We give authors the possibility to publish their top-quality papers in a well-established leading journal in the food and nutrition fields. The Journal will keep its rigorous criteria to screen high impact research addressing relevant scientific topics and performed by sound methodologies.
The Journal of Functional Foods aims to bring together the results of fundamental and applied research into healthy foods and biologically active food ingredients.
The Journal is centered in the specific area at the boundaries among food technology, nutrition and health welcoming papers having a good interdisciplinary approach. The Journal will cover the fields of plant bioactives; dietary fibre, probiotics; functional lipids; bioactive peptides; vitamins, minerals and botanicals and other dietary supplements. Nutritional and technological aspects related to the development of functional foods and beverages are of core interest to the journal. Experimental works dealing with food digestion, bioavailability of food bioactives and on the mechanisms by which foods and their components are able to modulate physiological parameters connected with disease prevention are of particular interest as well as those dealing with personalized nutrition and nutritional needs in pathological subjects.
