Within this formation, the lacunosum moleculare (LMol), polymorph dentate gyrus (PoDG), and oriens (Or) layer retained similar levels of PrP expression in 9P31-SlugCas9-HF-MM1 treated mice as the negative control mice, yet the radiatum (Rad) layer and molecular dentate gyrus (MoDG) were diminished in their PrP-dependent red fluorescence (compare left and right panels of Fig 7A). The gene discussed is PRNP; the disease is hydrops fetalis.
