AMD reduced tidal volume (TV), peripheral expiratory rate (PER), forced vital capacity (FVC), serum reduced glutathione (GSH) levels, Beclin, and LCII, while it elevated transform growth factor (TGF-β1) gene expression, serum malondialdehyde (MDA) level, alpha-smooth muscle actin (α-SMA), Smad3, phosphorylated signal transducer and activator of transcription (p-STAT3), and p62 lung content. Here, STAT3 is linked to age-related macular degeneration.
