Figure Lengend Snippet: HMGB2, RUVBL2, and RPAP2 promote IAV polymerase activity. A) Minigenome reporter assay in eHAP WT cells transfected with a non-targeting siRNA (siNT), two siRNA pools targeting both ANP32A and ANP32B (siANP32.1 and siANP32.2), or siRNA pools targeting 31 genes enriched in WT cells or 2 genes enriched in both WT and ANP32-KO cells. Cells were transfected with plasmids to reconstitute PR8 polymerase activity. Firefly luciferase activity was normalized to co-transfected Renilla luciferase levels. Putative replication-specific proviral factors are shown in green, replication-specific antiviral factors in red, and transcription-specific proviral factors in blue. Statistical significance was assessed compared to siNT using an unpaired t test. B-I) Minigenome reporter assay in A549 WT and HMGB2-KO cells (B-E) or WT and RUVBL2-KO cells (F-I) transfected with plasmids to reconstitute PR8 (B and F), Vic75 (C and G), Eng195 (D and H), and Tky05 (E and I) polymerase activity. Firefly luciferase activity was normalized to co-transfected Renilla luciferase levels. Statistical significance was assessed compared to WT using an unpaired t test. J-O) Accumulation of segment 4 (Haemagglutinin (HA)) vRNA (J and M), cRNA (K and N), and mRNA (L and O) in A549 WT and RPAP2-KO cells (J-L) or WT and HMGB2-KO cells (M-O) following infection with PR8 (MOI=3). Data is shown as the fold change over input (0hpi). Statistical significance was assessed at each timepoint following log transformation using multiple unpaired t tests, corrected for multiple comparisons using the FDR. For all panels: Data is shown as mean of n=3 technical repeats, representative of n=3 biological repeats. ns, not significant; *, p<0.05; **, p<0.01; ***, p<0.001; ****, p<0.0001.

Figure Lengend Snippet: (A) Tracing of oxygen consumption rate (OCR) basal and injection with 10 nM oleic acid (OA) or OA + 40 nM Etomoxir (Eto). (B) The sperm, after 1 hour of incubation with or without seminal vesicle secretions (SV) from nontreated (Ctrl) or flutamide-treated mice(Flu), were used for IVF, and the cleavaged oocytes were observed. The absolute number of oocytes collected from the oviduct and the cleavage rate are shown. (C) Western blot analysis for phosphotyrosine (P-Tyr) in capacitated spermatozoa (Ctrl; 1-hour incubation in HTF medium) and treated with SV from healthy mice or 10 nM oleic acid (OA). (D) Quantitative analysis of GLUT4 relative to α-tubulin obtained from Western blot. (E) Flow cytometric analysis of the sperm after 1 hour incubation in control medium (HTF) and medium containing SV or 10 nM OA, using fluorescein isothiocyanate-conjugated peanut agglutinin (PNA-FITC; to distinguish between acrosome-reacted and non-reacted cells) and propidium iodide (PI; to distinguish between dead and viable cells). (F) The percentage of viable sperm with an acrosome reaction (PI-, PNA-FITC+) was evaluated by flow cytometry in the 4th quadrant (4Q; red square). Data are mean ± SEM. At least three independent replicates. Percentage data were subjected to arcsine transformation before statistical analysis. (B) Dunnett’s test was used to analyze the cleavage rate. Different letters represent significantly different groups. (D,F) Differences between groups were assessed by one-way analysis of variance (ANOVA). When ANOVA was significant, differences among values were analyzed by Tukey’s Honest Significant Difference test for multiple comparisons.
