• Digoxin, HIF-1α, and Thyroid Eye Disease Fibrosis

  2026-09-16

  A 2026 Biochemical and Biophysical Research Communications study identifies HIF-1α as a mechanistic link between hypoxia, inflammation, fibrosis, STAT3 signaling, and GSDME-associated pyroptosis in thyroid eye disease. In primary orbital fibroblasts, Digoxin reduced these responses in a concentration-dependent manner, supporting further preclinical evaluation rather than establishing clinical efficacy.

• PTX3–TLR4/NF-κB/FGF21 in Femoral Head Necrosis

  2026-09-16

  Li et al. identify a PTX3–TLR4/NF-κB/FGF21 signaling axis that limits glucocorticoid-induced osteonecrosis of the femoral head by preserving osteogenesis and reducing apoptosis.
