PERK inhibition increases rhodopsin ER localisation in P23H-1 rats. P23H-1 rats were treated from P21-P35 with either (A, B) 100 mg/kg or (C, D) 10 mg/kg PERKi or vehicle. (A, C) Immunohistochemistry of rhodopsin (green) and BiP (red) immunoreactivity in the ONL and inner segment (IS). Scale bar 10 µm. (B, D) Rhodopsin-BiP co-localisation quantified by calculating the Pearson's and Mander's co-localisation coefficients using the JaCOP plug-in and ImageJ software, n = 18 images each from 3 vehicle-treated mice and 3 PERKi-treated mice. Values are means ± SEM, *P < 0.05, ***P < 0.001, unpaired two-sided Student's t test.
