Oxidative stress disperses Clu particles. (A, B) Clu particles are always present in wild type siblings (n = 44) (A) but always missing in SOD2 mutant follicles (n = 51). (C, D) SOD2 mutants have decreased levels of ATP (C), but not decreased levels of Clu protein (D). (E-E″) Live-image stills of a well-fed cluCA06604 follicle. Addition of H202 causes particles to disperse (n = 11). Green = Clu (A, B), blue = DAPI (A, B), white = Clu::GFP (E-E″). Error bars are S.E.M. Scale bar: 10μm in B for A, B, 40μm in E′ for E-E′.
