Age-related macular degeneration (AMD) mitochondria modulate epigenetic mechanisms in retinal pigment epithelial cells

825 views | Jun 23 2019

Nashine S et al. revealed that AMD mitochondria regulate epigenetic mechanisms i.e., methylation and acetylation status. Demethylation using 5-Aza-2'-deoxycytidine (DAC) caused differential expression of VEGF-A gene in AMD cells. Trichostatin A (TSA), an HDAC inhibitor, also influenced protein levels of VEGF-A, HIF1α, NFκB, and CFH in AMD cells. This study might advance the field of AMD research since in addition to highlighting the critical role of nuclear-mitochondrial interactions that influence epigenetic mechanisms in AMD patients, this work suggests epigenetic profiles as potential therapeutic targets for AMD.
