Figure 8. VPS35 D620N and WASH1 depletion impair ATG9A trafficking to autophagosomes.

Figure 8

(a) HeLa cells stably expressing GFP-VPS35 WT and D620N were transfected with mRFP-LC3 for 24 h, immunostained for endogenous ATG9A, and imaged by confocal microscopy. (b) Colocalization is expressed in terms of Mander’s coefficient M1 to indicate the proportion of LC3 intensities that also contain ATG9A intensities. A representative experiment of three independent experiments is shown, in which at least 33 cells were analysed per condition. Error bars indicate s.e.m., and ***P<0.001 by 2-tailed Student’s t-test. (c) HeLa cells depleted of WASH1 were transfected with GFP-LC3 for 24 h, immunostained for endogenous ATG9A, and imaged by confocal microscopy. (d) Colocalization expressed as M1, as in b. A representative experiment of two independent experiments is shown, in which at least 24 cells were analysed per condition. Error bars indicate s.e.m., and ***P<0.001 by 2-tailed Student’s t-test. Scale bars in (a,c), 10 μm. In b,d, colocalization was measured for the entire area of the cell slice in each image. In order to ensure that results were not confounded by diffuse nuclear staining often observed in the LC3 channel, the analyses were repeated with the nuclei excluded, and all of the results remained statistically significant.
