Ilex paraguariensis A.St.-Hil. improves lipid metabolism in high-fat diet-fed obese rats and suppresses intracellular lipid accumulation in 3T3-L1 adipocytes via the AMPK-dependent and insulin signaling pathways

Background: Obesity is closely associated with several chronic diseases, and adipose tissue plays a major role in modulating energy metabolism. Objective: This study aimed to determine whether Mate, derived from I. paraguariensis A.St.-Hil., amelio- rates lipid metabolism in 3T3-L1 adipocytes and high-fat diet (HFD)-fed obese Sprague-Dawley (SD) rats. Design: 3T3-L1 adipocytes were cultured for 7 days, following which intracellular lipid accumulation and expres- sion levels of lipid...
