The miR-155 can regulate genes involved in the TGF-β signaling pathway (p = 4 E-4), in the apoptosis pathway (p = 1 E-3) and several inflammatory pathways, that are also regulated by the set of miRNAs differentially expressed in Aβ-injected rats and in AMD patients. Here, TGFB1 is linked to age-related macular degeneration.
