Experimental details: Immunofluorescent analysis of PMP70 (green) in 3T3 cells. The cells were permeabilized with 0.1% Triton X-100 in TBS for 15 minutes, and blocked with 3% Blocker BSA in PBS (Product # 37525) for 15 minutes at room temperature. Cells were stained with a PMP70 rabbit polyclonal antibody (Product # PA1-650), at a dilution of 10 µg/mL in blocking buffer for at least 1 hour at room temperature, and then incubated with a Goat anti-Rabbit IgG Superclonal secondary antibody, Alexa Fluor 488 conjugate (Product # A27034) at a dilution of 1:1000 for 30 minutes at room temperature (green). Nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

Experimental details: Knockdown of PMP70 was achieved by transfecting A-431 cells with PMP70 specific siRNA (Silencer® select Product # s11616). Immunofluorescence analysis was performed on A-431 cells (untransfected, panel a,d), transfected with non-specific scrambled siRNA (panels b,e) and transfected with PMP70 specific siRNA (panel c,f). Cells were fixed, permeabilized, and labelled with PMP70 Rabbit Polyclonal Antibody (Product # PA1-650, 5 µg/mL), followed by Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, Alexa Fluor® 488 (Product # A27034, 1:2000). Nuclei (blue) were stained using ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962), and Rhodamine Phalloidin (Product # R415, 1:300) was used for cytoskeletal F-actin (red) staining. Reduction of specific signal was observed upon siRNA mediated knockdown (panel c,f) confirming specificity of the antibody to PMP70 (green). The images were captured at 60X magnification.

Experimental details: FIGURE 2 Autophagy inhibitors do not restore peroxisomal import of PTS1- and PTS2-targeted peroxisomal matrix proteins in primary PEX1-G843D fibroblasts. Immunoblot analysis of homogenates of primary fibroblasts from two PBD-ZSD patients homozygous for the PEX1-G843D mutation [PEX1-G843D(1) (A) and PEX1-G843D(2) (B) ] treated as described in Figure 1A . The protein levels of the PMPs ACBD5 and ABCD3 and the ratio of the processed over unprocessed forms of PTS1-targeted ACOX1 and PTS2- targeted thiolase were determined using specific antibodies. Below the ACOX1 bands, the corresponding ratios between the intensity of processed (50 kDa) over unprocessed (70 kDa) ACOX1 bands are indicated. Below the thiolase bands, the corresponding ratios between the intensity of processed (41 kDa) over unprocessed (44 kDa) thiolase bands are indicated. Below the ACBD5 and ABCD3 bands, the corresponding signal intensity relative to the tubulin band intensity, which was used as a loading control, is indicated. Homogenates of non-treated control fibroblasts and PEX1- fibroblasts (PEX1 -/- ) were used for reference. The effect of the different treatments on autophagy was assessed by determining the relative protein levels of the autophagy adaptor protein SQSTM1/P62 (P62; relative to tubulin levels) and the ratio of MAPILC3B-II (LC3-II) over MAPILC3B-I (LC3-I). Cells were incubated for 7 days with the different compounds, except for bafilomycin (24 h incubation). Experiments were repeated twice

( A, B ) Adipocytes at indicated days of cool temperature exposure ( A ; n = 5) or for 12 days ( B ; n = 6) were incubated with tritiated palmitate ( A ) or oleate ( B ) for 3 hours +/- 40 muM etomoxir. * significantly different from day 0 control at 37degC; p < 0.05). t indicates a difference from day 0 etomoxir treatment. ( C ) Cool adaptation increases mitochondrial fatty acid oxidation and peroxisomal proteins. ( D ) Primary adipocytes isolated from eWAT or sWAT were cultured in suspension at either 37degC or 31degC for 2 days. Expression of SCD1, CPT1alpha, MCKAT, and MTPbeta was then determined by immunoblot analyses; adiponectin, FABP4, and laminin were loading controls. ( E ) Elevated basal OCR of adipocytes at 31degC is partially dependent on oxidation of endogenous fatty acids. MSC-derived adipocytes cultured at 31degC or 37degC for 12 days were treated with vehicle, 20 muM etomoxir and/or 20 muM of atglistatin for 2 hours prior and during assay of OCR ( n = 8-10). ( F ) Four-day exposure at 31degC stimulates an increase in mitochondrial number as assessed by qPCR for 2 mitochondrial regions (CytoB, Cox-TMS) and 2 nuclear genes (glucagon, beta-globin; n = 3).

Experimental details: 6 FIG. Altered hepatic nuclear receptor expression and FXR agonists in malnutrition. (A-C) Relative concentrations of FXR and PPARalpha protein in liver, determined by western blot, reveal a profound decrease of PPARalpha expression in malnourished male livers (n = 3-4). (D) Relative expression of PMP70 correlates directly with PPARalpha protein levels in malnourished male livers (n = 3-4) and supports qualitative evaluation by electron microscopy revealing loss of hepatocyte peroxisomes (Supporting Fig. S8). (E) Targeted bile acid mass spectrometry from liver, plasma, and stool found total fecal bile acid levels to be significantly decreased in malnourished male mice. (F) Individual stool bile acid metabolites show multiple decreased bile acids and sex specificity (n = 6). Individual liver and plasma bile acid metabolites are shown in Supporting Fig. S9. Data in (B-D) are mean + SD. Box and whisker plots (E,F) show interquartile range (box), median (vertical line), and outliers (whiskers).
