Abstract (original English)
In beige adipocytes, UCP1-dependent thermogenesis can be driven by intracellular reactive oxygen species (ROS) generation. While ROS elevation also induces mast cell activation, serotonin synthesis and release from mast cells inhibits beige progenitor cell proliferation and browning. As a natural antioxidant and mast cell stabilizer, luteolin promotes adipocyte thermogenesis and inhibits mast cell activation. Thus, to activate adipocyte thermogenesis, how luteolin regulates ROS level in beige adipocytes and mast cells needs to be further investigated. In this study, mouse subcutaneous stromal vascular fraction (SVF) cells are induced to differentiate into beige adipocytes, and mouse bone marrow-derived mast cells (BMMCs) are activated with hydrogen peroxide (H 2 O 2 ). Intracellular ROS level is augmented in differentiated beige adipocytes and H 2 O 2 -activated BMMCs, and H 2 O 2 -activated BMMCs inhibited brown differentiation of SVF cells and thermogenesis of beige adipocytes. In beige adipocytes, unlike synthetic antioxidant N-acetylcysteine (NAC), luteolin elevates the expression of thermogenic and beige-selective marker genes and intracellular ROS generation. Contrarily, luteolin inhibits H 2 O 2 -induced mast cell activation and ROS generation. Further, luteolin partially reverses the inhibitory effects of H 2 O 2 -activated BMMCs on the brown differentiation of SVF cell
