    Pexophagy occurs in proportion to whole-cell peroxisome levels. (A) Immunoblot validation of Fr.1 from all conditions, alongside respective whole-cell extracts (inputs). Peroxisomal proteins: CAT, <t>ACSL1,</t> PEX11B, PEX19 and PEX3. LAMP2 and LC3B-II are lysosome and autophagosome protein, respectively. (B) Whole-cell extract peroxisomal protein profile. Shown are acute Vor-treated U937 cells (6,12,18 h), chronically-treated B8 (Vor) and B8 cells washed-off from Vor for one week, referred to as B8 washoff (WO). All samples were treated with CQ. ACTB is a loading control. (C) Relative mRNA expression of PEX genes in vehicle and Vor (2 μM)-treated U937 cells, Vor-maintained B8 (B8 [Vor]), and vehicle-cultured B8 (WO) cells. MAP1LC3B and FOXO1 are shown as positive controls for HDACi-induced transcriptional upregulation. All samples were normalized to the housekeeping gene ACTB. (D) Schematic of pexophagy. Ubiquitinated PEX5 is attached to the outer surface of the peroxisome and binds the cargo receptors SQSTM1 or NBR1, which facilitates peroxisomal engulfment into an expanding autophagosome (AP). (E) PEX5-Ubiquitin colocalization (+CQ) in vehicle (DMSO)-treated U937, Vor-treated U937, and B8 cells chronically maintained in Vor, with quantitation show below. (F) PEX5 and SQSTM1 colocalization, and (G) PEX5 and NBR1 colocalization (+CQ) in vehicle (DMSO)-treated U937, Vor-treated U937, and B8 cells chronically maintained in Vor. Insets shown for each condition (scale bar for D and E: 10 μm). (H) Number of colocalized puncta per condition (merge) from analyses of (F) PEX5 with SQSTM1, and (G) PEX5 with NBR1 are shown below respective images. (I) Co-immunoprecipitation of PEX5 with SQSTM1 (top), and corresponding inputs (below). All Vor treatments are 2 μM (18 h U937, chronic treatment B8), and CQ 25 μM (18 h).

    BMDMs were differentiated under NG conditions. A) Total cell lysates were prepared with (+) and without (-) LPS treatment (10 ng/ml for 24 hours). ACSL1 protein expression was determined by western blot with an anti-ACSL1 antibody. An anti-alpha tubulin antibody was used as a loading control. B) Bands were quantified using the Image studio 5.2. C) Cytoplasmic and membrane proteins were isolated to determine the localization of ACSL1 protein by western blotting as a function of LPS treatment. Alpha-tubulin (cytoplasmic protein) and Na+/K+ ATPase (membrane-associated protein) were used to confirm the fidelity of fractionation. D) Images were quantitated as in B with cytoplasmic ACSL1 protein normalized to tubulin and membrane ACSL1 protein normalized to Na+/K+ ATPase. The data presented are means ± standard error (n = 3); the p-value was calculated using student’s t-test. (*p < 0.05). E) Mitochondria were isolated from BMDMs, and ACSL1 abundance was determined by western blot with and without LPS treatment. The non-specific (ns) band serves as a loading control.

    Techniques Used:

    HEK293 cells cultured in HG conditions were transfected with Acsl1 -GLuc reporter (250ng; columns 1–7) and individually with p65/RELA (150ng; column 2) or CHREBP (150ng; column 3). Cells were transfected with Acsl1 -GLuc reporter and a fixed amount of p65/RELA (150ng; columns 4–7), along with increasing amounts of CHREBP (100ng, 150ng, 200ng, 250ng; columns 4–7, respectively). Total DNA was adjusted to 750ng with vector only. Luciferase assay was performed 48 hours post-transfection and shown as relative luciferase units (RLU). The data presented are means ± standard errors (n = 3); the p-value was calculated using one-way ANOVA. *p < 0.05. B) Western blot of lysates from panel A with antibodies against the Myc-tag on CHREBP, FLAG-tag on p65/RELA, and tubulin as a loading control. The p65/RELA blot for lanes 1–2 was run on a different gel than lanes 3–7 and denoted by a black line between lanes 2 and 3. Exposure times were the same.
    Figure Legend Snippet: HEK293 cells cultured in HG conditions were transfected with Acsl1 -GLuc reporter (250ng; columns 1–7) and individually with p65/RELA (150ng; column 2) or CHREBP (150ng; column 3). Cells were transfected with Acsl1 -GLuc reporter and a fixed amount of p65/RELA (150ng; columns 4–7), along with increasing amounts of CHREBP (100ng, 150ng, 200ng, 250ng; columns 4–7, respectively).

    A) Putative binding sites of CHREBP and p65/RELA on mouse Acsl1 . Arrows denote the region amplified by qPCR. B) Chromatin was immunoprecipitated from BMDMs differentiated in HG using an antibody against CHREBP and isotype-matched IgG control. C) Chromatin was immunoprecipitated from BMDMs differentiated in HG and stimulated with LPS (10ng/mL) for 1 hour using an antibody against p65/RELA along with isotype-matched IgG control. Percent of precipitated DNA compared to total input DNA is shown. The data are means with an error bar representing the spread of the mean from two independent experiments.

    Techniques Used: Binding Assay, Amplification, Immunoprecipitation

    A) We propose that in high glucose, CHREBP is depressed, and active nuclear CHREBP promotes the expression of Acsl1 . B) Under inflammatory conditions that activate the NF-kappa B via dismissal of the inhibitory protein I kappa B (IkB) that prevents NF-kappa B nuclear transport, Acsl1 transcription is induced. C) Acsl1 expression can be further increased by high glucose and inflammatory stimuli via CHREBP and NF-kappa B.

Peroxisomal proteins: CAT, <t>ACSL1,</t> PEX11B, PEX19 and PEX3. LAMP2 and LC3B-II are lysosome and autophagosome protein, respectively. (B) Whole-cell extract peroxisomal protein profile. Shown are acute Vor-treated U937 cells (6,12,18 h), chronically-treated B8 (Vor) and B8 cells washed-off from Vor for one week, referred to as B8 washoff (WO). All samples were treated with CQ. ACTB is a loading control. (C) Relative mRNA expression of PEX genes in vehicle and Vor (2 μM)-treated U937 cells, Vor-maintained B8 (B8 [Vor]), and vehicle-cultured B8 (WO) cells. MAP1LC3B and FOXO1 are shown as positive controls for HDACi-induced transcriptional upregulation. All samples were normalized to the housekeeping gene ACTB. (D) Schematic of pexophagy. Ubiquitinated PEX5 is attached to the outer surface of the peroxisome and binds the cargo receptors SQSTM1 or NBR1, which facilitates peroxisomal engulfment into an expanding autophagosome (AP). (E) PEX5-Ubiquitin colocalization (+CQ) in vehicle (DMSO)-treated U937, Vor-treated U937, and B8 cells chronically maintained in Vor, with quantitation show below.
