Abstract
This study investigated the effects of tanshinone IIA combined with rutin and squalene (RTS) on atherosclerosis (AS) associated with hyperlipidemia and the underlying mechanisms. Female New Zealand rabbits were subjected to a hyperlipidemia and AS model. Treatment with RTS for 4 weeks reduced the weight, and some serum lipid levels include serum TC, serum TG, serum LDL-C. RTS also improved lesions of the liver and aorta. In vitro analyses showed that RTS significantly activated LDLR-mediated hepatic lipid endocytosis, but blocking LDLR activation with si-SREBP2 attenuated the therapeutic effect, which demonstrated that RTS can activate the SREBP2/LDLR pathway mediating liver clearance of blood lipids. This study highlights the therapeutic potential of RTS in hyperlipidemia and AS. As a convenient form of a combination drug, RTS has shown considerable potential in the improvement of hyperlipidemia combined with AS.
期刊介绍:
The Journal of Food Biochemistry publishes fully peer-reviewed original research and review papers on the effects of handling, storage, and processing on the biochemical aspects of food tissues, systems, and bioactive compounds in the diet.
Researchers in food science, food technology, biochemistry, and nutrition, particularly based in academia and industry, will find much of great use and interest in the journal. Coverage includes:
-Biochemistry of postharvest/postmortem and processing problems
-Enzyme chemistry and technology
-Membrane biology and chemistry
-Cell biology
-Biophysics
-Genetic expression
-Pharmacological properties of food ingredients with an emphasis on the content of bioactive ingredients in foods
Examples of topics covered in recently-published papers on two topics of current wide interest, nutraceuticals/functional foods and postharvest/postmortem, include the following:
-Bioactive compounds found in foods, such as chocolate and herbs, as they affect serum cholesterol, diabetes, hypertension, and heart disease
-The mechanism of the ripening process in fruit
-The biogenesis of flavor precursors in meat
-How biochemical changes in farm-raised fish are affecting processing and edible quality
