Consequently, we have also determined the autophagy markers Beclin-1, Atg5, Atg7, and LC3 (participants in the macroautophagy process), and LAMP2A (involved in chaperone-mediated autophagy) using the Western blot technique to assess the role of this biochemical process in the evolution of RP. This evidence concerns the gene BECN1 and retinitis pigmentosa 1.
