A Electronmicroscopic images of cells containing enlarged nuclei in P120 PR-SET7ΔHepA livers and normal hepatocytes in control littermates (WT). White arrows indicate: (Nuc) nuclei; (ER) endoplasmic reticulum; (Mit) mitochondrium; (PM) plasma membrane; (a) swollen mitochondria; (b) swollen endoplasmic reticulum; (c) disorganized endoplasmic reticulum; (d) disrupted plasma membrane; and (e) disorganized pieces of endoplasmic reticulum encircling mitochondria to form autophagosomes.
