CoV RNA synthesis is confined to RO regions.Fig. 3.(A) Analysis of the amount of radioactive label incorporated into RNA as a function of the labelling time in SARS-CoV-infected Vero E6 cells (MOI 10), as measured by scintillation counting on the RNA isolated from the cells. The label was provided simultaneously to all the samples at 6 hpi. (B-D) EM detection by autoradiography. (B) Overview of a SARS-CoV-infected Vero E6 cell (MOI 10) were labelled for 20 min just before fixation at 7 hpi, and then processed for EM autoradiography. Autoradiography grains accumulate in the RO regions. N, nucleus; m, mitochondria; VCR, virion-containing regions; LD, lipid droplets. Scale bar, 1 μm. (C, D) Quantification of the autoradiography signal per subcellular structure (see also S1 Table). Labelling densities and relative labelling indexes (RLI) in different subcellular regions of (C) Vero E6 cells infected with SARS-CoV (MOI 10) or (D) Huh7 cells infected with MERS-CoV (MOI 5). Radioactively-labelled uridine was provided for the indicated periods of time immediately before fixation at 7 hpi and 12 hpi, respectively. Control mock-infected cells are excluded from the RLI plots, as RLI comparisons between conditions require the same number of classes (subcellular regions) and these cells lack ROs and virions.

Note that LC3-I is often very faint compared with LC3-II in HeLa cells under the protein extraction conditions we used (see Figure S1C). However, this was not a problem because one should relate LC3-II to tubulin (mean ± SEM). PI(5) P Regulates Autophagosome Biogenesis(C and D) HeLa cells stably expressing GFP-LC3 were treated as in (A) and then left in complete media (basal) or starvation media (HBSS) for 2 hr, then fixed and analyzed on a Cellomics ArrayScan system. Quantification of numbers of GFP-LC3 vesicles per cell in the different conditions is shown in (D) (mean ± SEM). (E) HeLa cells stably expressing GFP-mRFP-LC3 were treated as in (A) and analyzed on a Cellomics ArrayScan system. Quantification of numbers of autophagic vesicles (AV) or autolysosomes (AL) per cell in the different conditions is shown in the graph (mean ± SEM). (F and G) Western blot analysis of free ATG12 and ATG5ATG12 complex levels with anti-HA antibody in HeLa cells transfected with HA-ATG12 and ATG5 and loaded with exogenous lipids. We quantified the ratio of ATG5ATG12 versus free ATG12 by direct infrared fluorescence detection on an Odyssey Infrared Imaging System to assess ATG5-ATG12 conjugation efficiency (mean ± SEM). (H) HeLa cells transfected with GFP-PHD3X or GFP-PHD3X Znmut and RFP-LC3 for 16 hr were left in complete media (basal) or starvation media (HBSS) for 1 hr, then fixed and imaged on a confocal microscope. Empty arrowheads indicate PHD3X single-labeled structures, while filled arrowheads indicate PHD3X-LC3- and PHD3X-ATG16-positive structures. Bar, 10 μm. (I) HeLa cells transfected with GFP-PHD3X and RFP-LC3 for 16 hr were left in HBSS for 1 hr, then fixed and imaged on Elyra superresolution microscope. Final visualization was performed in Volocity 6.3 software using isosurface rendering of selected cropped regions of the data sets. Note that this rendering means that vesicles positive for green and red do not look yellow but have green and red on the surface. Representative cropped regions from different cells are shown. Bar, 1.13 μm. See also Figure S1.

SPPL2c downregulates SPPL3 and affects trafficking of membrane proteins in HEK293 cells.Figure 2A) SPPL2c overexpression causes a decrease on SPPL3 levels. Endogenous levels of SPPL3 were assessed in cells ectopically expressing wild type SPPL2c (SPPL2c WT) or catalytically inactive SPPL2c (SPPL2c D/A) by Western Blot. Non-transfected cells (-) or stably transfected but non-induced SPPL2c wt cells (n/i) served as controls. Note that SPPL3 expression is reduced in cells expressing SPPL2c wt. Data information: Expression levels of the ectopically expressed SPPL proteases are shown and Calnexin serves as loading control B) SPPL2c impairs secretion and maturation of glycan-modifying enzymes. Protein levels of endogenous EXTL3, B4GALT1, OGFOD3 and GnT-V were monitored in lysates of cells treated with control siRNA (siCtr) or with siRNA targeting SPPL3 (siSPPL3) and in cells ectopically expressing either SPPL2c or SPPL3 by Western Blot. In addition, the secreted forms (sEXTL3, sB4GALT1, sOGFOD3, sGnTV,) were analyzed in the corresponding conditioned media using Western Blot. Note that SPPL2c reduces secretion of the glycosyltransferases similar to SPPL3 knock down, but additionally induces a decrease of the mature glycosyltransferases in the cell lysate similar to ectopic expression of SPPL3. Data information: Expression levels of the ectopically expressed SPPL proteases are shown and Calnexin serves as loading control C) Processing of ectopically expressed GnT-V with an N-terminal Flag- and C-terminal V5-tag (Flag-GnTV-V5) was analyzed in lysates and conditioned media (sup.) of either SPPL2c wt or SPPL2c D/A expressing cells by Western Blot. Non-transfected cells (-) or stably transfected but non-induced SPPL2c wt cells (n/i) served as controls. In addition, maturation of the glycoproteins Nicastrin (NCT), Lamp2 and SPPL2a was monitored by detection of the respective mature (mat) and immature (im) version. Note that secretion of GnT-V is impaired in SPPL2c wt expressing cells and immature glycoproteins accumulate. Data information: Expression levels of the ectopically expressed SPPL proteases are shown and Calnexin serves as loading control D) SPPL2c induces mislocalization of GnT-V. Ectopically expressed GnT-V was visualized by immunofluorescence staining using the anti-V5 antibody either in control cells (Ctr) or in cells co-expressing either SPPL2c wt or SPPL2c D/A. The ER was stained using the anti-BiP antibody and the Golgi with the anti-TGN46 antibody. While in control cells GnT-V mainly localizes to the Golgi, its localization shifts to more ER-like structures in SPPL2c expressing cells. Scale bar 5 µm.
