VDAC1-specific siRNA abrogates Parkin translocation to mitochondria after 2 h, and mitochondrial clearance after 24 h, of CCCP treatment.figf8VDAC1-specific siRNA abrogates Parkin translocation to mitochondria after 2 h, and mitochondrial clearance after 24 h, of CCCP treatment. Both effects can be rescued by re-transfection with wild-type VDAC1. (a) Immunofluorescence and (b) western blot of siRNA-transfected HeLa cells used in c-g demonstrate partial silencing of endogenous VDAC1. (a) Silenced cells were stained with anti-HtrA2/Omi, a mitochondrial marker (pseudo coloured; blue), and anti-VDAC1 (red) antibodies. (b) Lysates from silenced cells were subjected to western blot analysis and probed with an anti-VDAC1 antibody, while TOM20 and β-actin probing served as loading controls. (c-e) Control siRNA- or VDAC1 siRNA-silenced HeLa cells were transfected with the indicated combinations of EGFP-Parkin wild-type, VDAC1-Flag wild-type or appropriate empty vector controls. Cells were treated with CCCP for 2 h and 24 h and stained with anti-HtrA2/Omi (pseudo coloured; blue) and anti-Flag (red) to visualize mitochondrial morphology and re-transfected VDAC1, respectively. Wild-type Parkin was visualized by EGFP epifluorescence (green). Parkin-positive cells are surrounded by a line. Representative pictures of three independent experiments are shown. Scale bars, 10 μm.

A549 cells were transiently transfected with the indicated siRNA (control and KPT conditions = siNT) at low or high confluency. 48 hours later, cells were incubated overnight in the presence of XPO1 inhibitors KPT-185 and KPT-330 (final concentration = 1 µM) or with DMSO for all other conditions. The next day, cells were fixed and stained for endogenous YAP1.

The entire ectodomain (residues 19-171) was used for immunization of rats to generate TREM2 antibodies. sTREM2 (soluble TREM2), CTF (C-terminal fragment). (B) Immunoblot analysis of membrane fractions of HEK293 Flp-In cells stably overexpressing both mouse TREM2 and mouse DAP12 upon treatment with 4D9 antibody reveals increased levels of membrane-bound TREM2 similar to what can be achieved by ADAM protease inhibition using the GM6001 inhibitor. An isotype antibody was used as a negative control. Calnexin served as a loading control. Levels of membrane-bound TREM2 were quantified by MSD ELISA. Data represent the mean ± SEM (n=3). One-way ANOVA, Tukey's post hoc test; p (DMSO vs GM) = 0.0011; p (DMSO vs isotype) = 0.992; p (isotype vs 4D9) = 0.0005; n.s., not significant. (C) Immunoblot analysis of conditioned media from HEK293 Flp-In cells stably overexpressing both mouse TREM2 and mouse DAP12 upon treatment with 4D9 antibody reveals decreased levels of sTREM2 similar to what can be achieved by ADAM protease inhibition using the GM6001 inhibitor. An isotype antibody was used as a negative control. sAPPα served as a loading control. Note that heavy and light chains of the antibodies used for treatment are also detected and annotated. Levels of sTREM2 were quantified by MSD ELISA. Data represent the mean ± SEM (n=3). One-way ANOVA, Tukey's post hoc test; p (DMSO vs GM) < 0.0001; p (DMSO vs isotype) = 0.6372; p (isotype vs 4D9) < 0.0001; n.s., not significant. (D) 4D9 antibody selectively detects TREM2 on the cell surface of HEK293 Flp-In cells stably overexpressing mouse TREM2 and mouse DAP12. An anti-HA antibody was used as a positive control while empty vector transfected HEK293 Flp-In cells were used as a negative control. Scale bar= 10µm. (E) Peptide ELISAs detect anti-mouse TREM2 antibody binding to tiled stalk region peptides, full length stalk peptide or a truncated ADAM cleavage site peptide. The binding epitope of 4D9 antibody is located 12 amino acids N-terminal of the ADAM cleavage site at His 157. (F) Sequence comparison of mouse TREM2 and human TREM2 shows substantial sequence conservation around the 4D9 epitope (upper panel). Immunoblot analysis demonstrates that antibody 4D9 is highly specific for mouse TREM2 and does not detect human TREM2 or mouse TREM1 (lower panel). (G) 4D9 binding to mouse TREM2 ECD is competed off by a stalk region peptide. A competition ELISA demonstrates that a dose titration of stalk peptide reduces binding of 4D9 to TREM2 ECD with an EC50 of 1.3uM. Data represent the mean ± SEM (n=3). (H) Surface plasmon resonance binding kinetics of increasing concentrations of 4D9 antibody to mouse TREM2 ectodomain evaluated by BIAcore, Kon = 5.9 x 105 M-1s-1, Koff = 4.0 x 10-5 s-1, KD = 68 pM. 4D9 binding to human TREM2 or mouse TREM1 was undetectable.
