VCP and retinal degeneration: Since VCP inactivation (which suppressed degeneration) also increased the levels of Rh1 oligomers and both Rh1WT and Rh1P37H-expressing flies (at P20-P30) displayed high levels of oligomers (despite clear differences in retinal integrity), the presence of these Rh1 oligomers is probably not the cause of retinal degeneration in the Rh1P37H;Rh1+/+ retina.
