HBEGF and age-related macular degeneration: In the context of wet age-related macular degeneration (AMD), geniposide (GEN), a GLP-1RA, is found to downregulate HB-EGF (heparin-binding epidermal growth factor) secretion from retinal pigment epithelium (RPE) cells under hypoxic conditions through the miR-145-5p/NF-κB signaling axis.
