Article Title: Resveratrol Attenuates Obesity by Inducing GDF15 Expression via the p38‐ ATF3 Signaling Pathway

doi: 10.1002/fsn3.72052

Figure Lengend Snippet: Proposed model for resveratrol‐induced body weight reduction via the GDF15 pathway. Schematic illustration summarizing the proposed mechanism: Resveratrol activates the p38 MAPK signaling pathway, leading to upregulation of ATF3. This transcription factor then promotes GDF15 expression and secretion in peripheral tissues. The elevated circulating GDF15 acts on the brain, potentially through activation of the ERK pathway in the hypothalamus, resulting in reduced food intake and subsequent protection against diet‐induced obesity.
