Article Title: GDF15 orchestrates mitochondrial-immune crosstalk via SMAD7-HIF-1α-PKM2 cascade to attenuate septic liver injury

doi: 10.3389/fimmu.2025.1712741

Figure Lengend Snippet: GDF15 preserves mitochondrial homeostasis in LPS-stimulated macrophages through dual regulation of SMAD7 and PKM2 pathways. (A) HIF-1α and SMAD7 expression in RAW264.7 macrophages across conditions: Untreated, LPS, LPS with rAAV8-mGdf15 overexpression (LPS+GDF15), and LPS with GDF15 knockdown (si-GDF15). β-actin: loading control.(HIF-1α suppression and SMAD7 induction by GDF15.) (B) Cytosolic and nuclear PKM2 protein levels. Lamin B1 (nuclear) and α-tubulin (cytosolic) markers validate fractionation efficiency. Study groups and individual replicates are identified in the figure key.(PKM2 subcellular redistribution modulated by GDF15.) (C) Immunofluorescence of PKM2 (red) and nuclei (DAPI, blue). Arrows indicate nuclear PKM2 accumulation. Scale bar: 15 μm.(Nuclear PKM2 enrichment upon LPS challenge mitigated by GDF15 and exacerbated by GDF15 knockdown.).

Figure Lengend Snippet: SMAD7 activation suppresses HIF-1α to mediate GDF15-dependent mitochondrial protection in LPS-challenged macrophages. (A) Pharmacological SMAD7 activation by Asiaticoside (20 μM, 48 h). β-actin: loading control. (B) HIF-1α expression under LPS challenge: LPS alone, LPS + AVV-GDF15, or LPS + SMAD7 activation (Asiaticoside). β-actin: loading control. (C) HIF-1α modulation across conditions: LPS, LPS + si-GDF15, LPS + Asiaticoside, or LPS + si-GDF15 + Asiaticoside. β-actin: loading control.
