Figure 3  (A-C) Tracks generated through automated tracking were plotted to a common origin to visualize parasite dispersal P. berghei (A), P. yoelii (B) and P. falciparum (C) at 5, 10, 30 and 60 min after intradermal inoculation. For each timepoint, the tracks are representative of the average displacement of the entire sporozoite population. Track numbers used for each timepoint were: 5 min, 40 tracks; 10 min, 32 tracks; 30 min, 25 tracks; 60 min, 21 tracks. (D-F) Displacement of P. berghei (D), P. yoelii (E) and P. falciparum (F) sporozoites 5-120 min after inoculation in box and whisker plots with whiskers displaying the 10-90 percentiles and values below and above the whiskers shown individually. Horizontal lines show median displacement at each time point. Percentage values in boxes indicate the fraction of tracks displacing over 75 micrometers at each time point. Within a given species, the difference in sporozoite displacement between 5 min and 120 min is statistically significant (Kruskal-Wallis test: P. berghei p<0.0001, P. yoelii p<0.0001, P. falciparum p<0.01). Comparisons between species showed no statistically significant difference in displacements for any given time point, with the exception of the 10 min time point in which there was a significant difference between P. berghei and P. falciparum (Kruskal-Wallis test, *p<0.05). For panels (D-F), a varying number of videos were processed for each time point after inoculation: (D) Same dataset as used for Figure 2D: 5 min (3 videos/203 tracks), 10 min (6 videos/292 tracks), 20 min (4 videos/184 tracks), 30 min (6 videos/235 tracks), 60 min (7 videos/162 tracks) and 120 min (6 videos/151 tracks).

Figure 2A selection of genes with significantly altered expression (Bonferroni-adjusted p < 0.1; normal, n=8; tumor and residual, n=4), targeted metabolites with significantly altered levels (Benjamini-Hochberg-adjusted p ≤ 0.05; normal, tumor, and residual, n=8; WT n=2), and significant reporter metabolites (top 5% with p < 0.1) of core metabolic processes are presented. A two-sided Wald test with a Negative Binomial GLM was used as test statistics for gene expression. For metabolite levels, statistics were calculated using the limma package in R with the significance threshold corresponding to a Benjamini-Hochberg adjusted p-value ≤ 0.05 (residual compared to normal). For the reporter metabolites, a gene set enrichment analysis was performed from a theoretical null distribution using the reporter method Bonferroni-adjusted p-values of the expression analysis were used as gene-level statistics. Metabolite-gene sets were derived from a genome-wide human metabolic model (HMR2), with genes mapped to mouse orthologs Flux balance analysis predicted metabolic fluxes, which are altered in the corresponding (overlaid) pathways. Significantly altered gene expressions and metabolites were used to inform the predictions. Number of replicates corresponds to individual mice used to derive organoids.
Atg9 is epistatic to Ypt1 in macro-ER-phagy and not to the ER-exit regulator Sec12, which is not defective in this process.Fig 3A-C.ATG9 was deleted in ypt1-1, WT and sec12ts mutant cells and the effect of overexpression of GFP-Snc1-PEM was determined in single and double mutant cells. Experiments were performed as described for Fig 1A-1C, respectively. A. Snc1-PEM is increased ~3 fold in atg9∆ and sec12ts as compared to ~20 fold in ypt1-1 mutant cells. Importantly, atg9∆ is epstatic to the ypt1-1, but not to the sec12ts, mutation. Left, immuno-blot analysis, increase of the protein level in mutant versus the WT cells is shown under the blot; right, a bar graph summarizing the quantified data . Whereas deletion of ATG9 in ypt1-1 mutant cells results in three fold lower accumulation of GFP-Snc1-PEM in aberrant structures (85% to 27%), its deletion in sec12ts mutant cells results in two fold increased accumulation (~40% to ~80%). Shown from top to bottom: DIC, GFP, and % cells with intracellular Snc1-PEM structures. C. Deletion of ATG9 in ypt1-1 mutant cells overexpressing Snc1-PEM results in ~3.5 lower UPR (p-value<0.0005), but a slightly increased UPR in sec12ts mutant cells (p-value = 0.05). D. Atg9 is present on aberrant ER structures that accumulate in ypt1-1 mutant cells. WT and ypt1-1 mutant cells expressing Atg9-mCherry from the chromosome and GFP-Snc1-PEM from a 2μ plasmid were analyzed by live-cell microscopy. Whereas in WT cells (top), the GFP-Snc1-PEM localizes to the cell membrane and Atg9-mCherry to intracellular puncta, the two proteins co-localize in 100% of the ypt1-1 mutant cells (bottom) that accumulate intracellular GFP-Snc1-PEM structures (~80%). Shown from left to right: DIC, GFP, mCherry, merge, % cells with intracellular Snc1-PEM, and % cells with co-localization (number of cells with observed phenotype / total number of cells analyzed). E. GFP-Snc1-PEM is delivered to the vacuole for degradation in sec12ts mutant cells. Accumulation of GFP-Snc1-PEM in vacuoles of sec12ts mutant cells, with and without deletion of the vacuolar protease Pep4, was determined using the FM4-64 dye, which labels the vacuolar membrane. Deletion of PEP4 in sec12ts mutant cells results in an increase percent of cells in which GFP-Snc1-PEM accumulates inside the vacuole (from 8% to 100%). Shown from left to right: DIC, GFP, FM4-64 (vacuolar membrane), merge, % cells with aberrant GFP-Snc1-PEM structures, % cells with GFP-Snc1-PEM outside vacuole, and % cells with GFP-Snc1-PEM inside the vacuole. +/- and error bars represent STDEV. Results in this figure represent at least two independent experiments.

Figure 4A Immunoblot analysis of immunoprecipitated Flag-tagged histone H2B with anti-Flag (bottom panel) or anti-SUMO (upper panel) antibodies in WT, ulp2Δ, SUMO-all KR or ulp2Δ SUMO-all KR strains carrying empty vector or pRS426-FLAG-HTB1. One, two or three asterisks represent mono, di and polysumoylated histones, respectively. Note that the apparent diSUMO-H2B species (**) in ulp2Δ SUMO-all KR cells migrates more slowly than H2B linked to a SUMO dimer, suggesting that this species likely represents a low level of H2B with SUMO attached to two different histone lysines (lane 8; also see weaker band in lane 6). B Yeast strains of the indicated genotypes and carrying a YCplac33-ULP2 cover plasmid were streaked on SD+5-FOA to evict YCplac33-ULP2; cells were grown at 30°C for 3 days. C Mutant htb1-K123R ulp2Δ and htb1-K123R ULP2 strains with a pRS316-ULP2 cover plasmid were grown on the indicated plates at 30°C for 2-3 days. Three double mutant isolates were tested in parallel.

E Yeast strains of the indicated genotypes and carrying a YCplac33-ULP2 cover plasmid were streaked on SD+5-FOA to evict YCplac33-ULP2; cells were grown at 30°C for 3 days.
Fig.Figure 7The relative mtDNA copy number was determined by the ratio of mitochondrial DNA-encoded Cytochrome B (CytB) and nuclear-encoded NADH dehydrogenase (ubiquinone) flavoprotein 1 (Ndufv1) genes in GC and TA from HSA-Cre and control mice. Mitochondria-encoded gene and Nuclear-encoded gene expression levels by quantitative RT-PCR in GC muscles from 4-month-old HSA-Cre and control mice. Electron micrographs of HSA-Cre EDL muscles of 3-month-old mice showed that mitochondria are almost exclusively positioned at the two sides of Z lines in EDL fibers from control mice (black arrows). On the other hand, in Lipin1 deficient EDL fibers mitochondria are more often clustered and display electron-dense contact sites (white arrows). Scale bars: 0.20 μm. Ultrastructural analysis of HSA-Cre EDL muscles revealed the presence of numerous autophagic vacuoles of different morphologies (autophagosomes and lysosomes, black arrows; multilamellar bodies, white arrow) containing amorphous material and possibly degraded mitochondria (M). Scale bars: 0.50 μm
