<p><strong>Figure </strong><strong>3</strong><strong>:</strong> <strong>Large conformational changes of the PHD identified by FRET</strong>.</p> <p>(<strong>A</strong>) Design of a functional dynamin mutant to probe PHD stalk interactions. Minimal structure of the PHD and the PHD-Stalk interface showing the location of important residues discussed in this study. The unresolved loop L1N<sup>S</sup> in the stalk hosts the IAEDANS label and is sensitive to the two tryptophans (W525 and W542) in the PHD. The distance between two introduced cysteines (S357C and native C602) used to construct a double cysteine Dyn1 is also shown. (<strong>B</strong>) Comparison of emission spectra of various IAEDANS-labeled Dyn1 RCL variants (D352C, Y354C, S357C, I365C, H367C), upon Trp excitation at 295 nm. (<strong>C</strong>) FRET transfer upon excitation is contributed by two neighboring Trps (W525 and W542); Substitution by Phe resulted in significant loss of FRET. (<strong>D</strong>) IAEDANS emission kinetics upon addition of lipid nanotubes with or without PI4,5P<sub>2</sub> (ex=295). The arrow indicates addition of lipids.</p>

<p>(<b>a</b>) Schematic view of human Parkin structure (UBL, ubiquitin-like domain; R0, RING0/unique Parkin domain; R1/2, RING finger domains; IBR, in-between-ring domain). Parkinson's disease-associated mutations and the Parkin fragments used are indicated. (<b>b</b>) Parkin is recruited selectively to depolarized mitochondria and directs mitophagy. HeLa cells transfected with HA–Parkin were treated with CCCP for the indicated times. Mitochondria were stained by anti-TOM20 (pseudo coloured; blue) and a Δ&PSgr;m-dependent MitoTracker (red). Parkin was stained with anti-HA (green). Without treatment, mitochondria are intact and stained by both mitochondrial markers, whereas Parkin is equally distributed in the cytoplasm. After 2 h of CCCP treatment, mitochondria are depolarized as shown by the loss of MitoTracker staining. Parkin completely translocates to mitochondria clustering at perinuclear regions. After 24 h of CCCP treatment, massive loss of mitochondria is observed as shown by the disappearance of the mitochondrial marker. Only Parkin-positive cells show mitochondrial clustering and clearance, in contrast to adjacent untransfected cells. Scale bars, 10 μm. (<b>c</b>) Pathogenic Parkin mutations abrogate mitochondrial translocation and/or clearance. HeLa cells transfected with Flag–Parkin wild-type or pathogenic mutants were treated with CCCP and stained with anti-Flag (green), anti-TOM20 (red) and Hoechst33342 (blue). Representative merged images are shown. Scale bars, 10 μm.

<p>(<b>a</b>, <b>b</b>) Stable Mito-DsRed (pseudo coloured; blue)-expressing HeLa cells were transfected with Flag–Parkin wild-type or pathogenic mutants. Cells were treated with CCCP before immunostaining of Parkin with anti-Flag (green) and endogenous poly-ubiquitin with a specific antibody FK1 (red). (<b>a</b>) In contrast to pathogenic mutations, wild-type Parkin shows colocalization with poly-ubiquitin after 6 h of CCCP treatment at the site of condensed mitochondria. (<b>b</b>) After 24 h of CCCP treatment, K161N and R275W Parkin mutants colocalize with both poly-ubiquitin and mitochondria. In contrast, translocation-deficient Parkin mutants K211N, T240R and G430D lack the mitochondria-associated poly-ubiquitin signal. Representative images are shown. Scale bars, 10 μm. Complementary immunostaining of untreated cells and quantification of colocalization of Parkin, mitochondria and poly-ubiquitin upon CCCP treatment are shown in <sir rid="s1">Supplementary Information, Fig. S3a, b and c</sir>, respectively. (<b>c</b>, <b>d</b>) Parkin-directed mitophagy specifically involves linkage of ubiquitin through lysines 27 and 63. HeLa cells were transfected with EGFP–Parkin wild-type and ubiquitin lysine variants and treated with CCCP before immunostaining with anti-HtrA2/Omi, as a mitochondrial marker (pseudo coloured; blue) and anti-His (red) to detect ectopic ubiquitin. Parkin was visualized by its fusion to EGFP (green). (<b>c</b>) Note that only wild-type, K27 and K63 6×His-tagged ubiquitin variants are colocalized with condensed mitochondria and EGFP–Parkin after 6 h of CCCP treatment. All other ubiquitin mutants interfere with Parkin translocation to mitochondria. (<b>d</b>) Only co-expression of K27 or K63 ubiquitin recapitulates mitochondrial clearance similarly to 6×His-tagged wild-type ubiquitin after 24 h of CCCP treatment. Representative images are shown. Scale bars, 10 μm. Immunostaining of untreated cells and all other ubiquitin variant combinations tested are shown in <sir rid="s1">Supplementary Information, Fig. S4a and b, c</sir>, respectively. WT, wild-type; PolyUb, poly-ubiquitin.</p>

<p>(<b>a</b>, <b>b</b>) Stable Mito-DsRed (pseudo coloured; blue)-expressing HeLa cells were transfected with Flag–Parkin wild-type or pathogenic mutants. Cells were treated with CCCP for the indicated times before immunostaining with anti-Flag (green) and anti-p62 (red). (<b>a</b>) In contrast to the pathogenic mutants, wild-type Parkin colocalizes with p62 at the site of clustered mitochondria, after 6 h of CCCP treatment. (<b>b</b>) After 24 h of CCCP treatment, wild-type Parkin-transfected cells show complete loss of mitochondria, whereas K161N and R275W Parkin mutants colocalize with both p62 and mitochondria. In contrast, translocation-compromised mutants K211N, T240R and G430D, lacking the mitochondria-associated poly-ubiquitin signal (<figr rid="f4">Fig. 4b</figr>), did not colocalize with p62. Representative images of four independent experiments are shown. Data from untreated control cells and quantification of colocalization of Parkin, mitochondria and p62 upon CCCP treatment are shown in <sir rid="s1">Supplementary Information, Fig. 5a and b, c</sir>, respectively. (<b>c</b>, <b>d</b>) Control siRNA- or <i>p62</i> siRNA-silenced HeLa cells were transfected with EGFP–Parkin wild-type. Cells were treated with CCCP for the indicated times and stained with anti-TOM20 (pseudo coloured; blue) to visualize mitochondrial morphology and anti-p62 (red) to monitor silencing efficiency. Parkin wild-type was visualized by EGFP epifluorescence (green). Parkin-positive cells with cleared mitochondria are surrounded by a line.

<p>(<b>a</b>) Time-course experiment of HeLa cells transfected with Flag–Parkin wild-type and treated with CCCP for the indicated periods. Total lysates were prepared, and western blots were probed with specific anti-Parkin, anti-PINK1, anti-TOM20 and anti-VDAC1 antibodies. β-Actin probing served as a loading control. All of the proteins detected are endogenously expressed, except Flag–Parkin. (<b>b</b>) Pathogenic Parkin mutants fail to poly-ubiquitylate endogenous VDAC1 in response to CCCP treatment. HeLa cells were transfected with empty vector (-), Flag–Parkin wild-type or pathogenic mutants along with 6×His-tagged ubiquitin wild-type for 24 h. Cells were treated with CCCP for 6 h and subsequently protein lysates were prepared in urea buffer. Denaturing conditions of Ni-NTA affinity purifications were used to specifically pulldown only proteins covalently modified with 6xHis-tagged ubiquitin. Western blots of protein lysates and purified Ni-NTA agarose elutions were probed with anti-VDAC1, anti-TOM20 and anti-Parkin antibodies. Modification of VDAC1 was observed in cells expressing Parkin wild-type and the functional mutant G328E, whereas non-functional mutants did not have this effect. (<b>c</b>) In response to CCCP treatment, Parkin catalyses predominantly K27-linked poly-ubiquitin chains on endogenous VDAC1 and is itself strongly poly-ubiquitylated. HeLa cells were transfected with an empty vector (-) or Flag–Parkin wild-type along with 6×His-tagged ubiquitin variants for 24 h. Treatment of cells, preparation of lysates and Ni-NTA purification were performed as described in <b>c</b> and probed for Parkin, VDAC1 and β-actin. WT, wild-type; Ub, ubiquitin.</p>

<p><i>VDAC1</i>-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. (<b>a</b>) Immunofluorescence and (<b>b</b>) western blot of siRNA-transfected HeLa cells used in <b>c</b>–<b>g</b> demonstrate partial silencing of endogenous VDAC1. (<b>a</b>) Silenced cells were stained with anti-HtrA2/Omi, a mitochondrial marker (pseudo coloured; blue), and anti-VDAC1 (red) antibodies. (<b>b</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. (<b>c</b>–<b>e</b>) Control siRNA- or <i>VDAC1</i> 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.

(<strong>A</strong> and <strong>B</strong>) Culture supernatants were harvested, and the levels of TNF-α, IL-6, IL-12p40, and IL-10 were measured by ELISA. (<strong>C</strong>) Cells were harvested and then subjected to IB for the phosphorylated forms of AKT, MAPK (ERK, p38, JNK), IκBα, total forms of IκBα. αActin was used as a loading control (left). The densitometric values were calculated from the ratios of protein levels relative to actin (right). Data shown are the means ± SD of three experiments (<strong>A</strong> and <strong>B</strong>). Data shown are representative of five independent experiments with similar results (<strong>C</strong>). Statistical significance was determined by Student's <em>t</em>-test with Bonferroni adjustment (*, P &lt; 0.05; **, P &lt; 0.01; ***, P &lt; 0.001) compared with rVector.</p> </sd-panel>

Mycobacterium tuberculosis Rv2626c-derived peptide as a therapeutic agent for sepsis
2020
Figure 5
<sd-panel> <p><strong>Figure 5. Design and expression of Tuftsin-conjugated Rv2626c peptide-based protein.</strong></p> <p>(<strong>A</strong>) Schematic in design of rRv2626c and its mutants. (<strong>B</strong>) Bacterially purified 6xHis-rRv2626c and analyzed by Coomassie blue staining (left) or immuno blotting (IB) with αHis (right). (<strong>C</strong>) BMDMs were incubated with rRv2626c-CA, rRv2626c-DN, or rVehicle for the indicated times and then cell viability measured with MTT assay. (<strong>D</strong>) BMDMs were pretreated with rRv2626c-WT, rRv2626c-CA, or rRv2626c-DN for 1 h, and stimulated with 100 ng/ml LPS for 18 h. Culture supernatants were harvested, and the levels of TNF-α, IL-6, IL-12p40, and IL-10 were measured by ELISA. (<strong>E</strong>) Myc-Rv2626c-expressing Raw264.7 or THP-1 cells were pretreated with rRv2626c-WT (2.5 μg/ml), rRv2626c-CA (10 ng/ml), rRv2626c-DN (2.5 μg/ml), for 1 h, and stimulated with 100 ng/ml LPS for 30 min, followed by IP with αMyc or αTRAF6, IB with αMyc and ubiquitin. WCLs were used for IB with αMyc, αTRAF6, αHis or αActin. The data are representative of five independent experiments with similar results (<strong>B</strong> and <strong>E</strong>). Data shown are the means ± SD of three experiments (<strong>C</strong> and <strong>D</strong>). SC, solvent control (PBS).</p> </sd-panel>
