PageRuler Prestained Protein Ladder was used for molecular size estimation. Shown is the section of the blot that contains the CaiT band. The complete gel is presented in Fig. S6. (b) Initial rates of counterflow (black) and maximum accumulation of carnitine in E. coli JW0039 (white) were determined as described in the legend of Fig. 3 . As negative control, cells carrying pET21a ( nc ) were used. (c) Initial rates of counterflow (black) and maximum accumulation (white) of carnitine catalyzed by CaiT variants in proteoliposomes. CaiT was purified and reconstituted as described 1 . The lipid to protein ratio of the resulting proteoliposomes was 100:1 (w/w). Proteoliposomes were preloaded with 10 mM unlabeled L-carnitine overnight. Aliquots of the proteoliposome suspension (1–2 µg of protein) were then diluted into 400 µL buffer containing 4.5 µM L-[methyl- 14 C]carnitine (55 Ci/mol) resulting in a final carnitine concentration of 54.5 µM. As negative control, proteoliposomes not preloaded with unlabeled carnitine ( nc ) were used and the obtained transport rates were used for correcting the data. Carnitine counterflow with cells or proteoliposomes was assayed at 25 °C under aerobic conditions using a rapid filtration method as described 1 . (d) Michaelis-Menten kinetics of L-carnitine counterflow in proteoliposomes reconstituted with wild-type CaiT (WT) or CaiT-D288A.

    Microfilament inhibitors suppress the AngII-mediated increase in COX-2 expression by preventing HuR binding to the corresponding mRNA. ( A ). HMC cells were treated for 2 h with either vehicle (−) or with AngII, or together with different microfilament inhibitors as indicated. Inhibitors were preincubated for 30 min (Lat.A) or 4 h (Blebbistat.) before the addition of AngII. To achieve transcriptional induction of different HuR target genes, cells were stimulated for 16 h with a cytokine mix containing IL-1β and TNFα (both at 2 nM) before AngII treatment. Steady-state mRNA levels of COX-2, cyclin A and cyclin D 1 were quantified by qRT-PCR using β-actin as a normalization control. Results are depicted as relative mRNA levels (%) in comparison with cytokine-stimulated conditions (vehicle), which were set to 100% and are means ± SD (n=3). ** P ≤ 0.01, *** P ≤ 0.005 compared with cytokine-induced conditions ## P ≤ 0.01 and ### P ≤ 0.005, compared with cytokine plus AngII-treated conditions. ( B ). Reduction of AngII-mediated stabilization of cytokine-triggered COX- 2 mRNA by blebbistatin (left panel) or latrunculin A (right panel). Quiescent HMC were treated for 20 h with a cytokine mixture containing IL-1β and TNFα (both at 2 nM) before the administration of Act D, which was added 30 min before AngII (filled triangles). Importantly, the indicated cytoskeletal inhibitors were given 4.5 h before the addition of AngII and remained for the indicated times with vehicle (open circles) or with 0.1 µM AngII (open squares) before cells were harvested and extracted for total cellular RNA. Steady-state mRNA levels of COX-2 were determined by qRT-PCR using β-actin mRNA as a normalization control. Graphs show means ± SD (n = 3) and depict the percentage of remaining COX-2 mRNA levels compared with the content of steady-state COX-2 mRNA measured immediately before the addition of Act D (0 h). ( C ). HMC were treated similarly as described in (A) before total cell lysates were assayed by IP using an anti-HuR antibody (gray bars), or the same amount of isotypic <t>IgG</t> (open bars). HuR-bound COX-2 mRNA was determined by pulldown RT assays. Data shown are means of two independent experiments and are depicted as fold induction versus cytokine-treated cells.

    AngII promotes a physical interaction of HuR with non-muscle myosin IIA, which structurally depends on phosphorylated S318 within the RRM3. ( A , upper panel). Schematic representation of c-myc-tagged wild-type HuR and different deletion mutants bearing truncations in the specific HuR domains. (A, lower panel). HMC were transfected with the indicated c-myc-HuR coding plasmids. Seventy-two hours after transfection, cells were treated without (−) or with AngII (+) for 2 h. Thereafter, c-myc-tagged HuR proteins were immunoprecipitated with an anti-c-myc antibody (IP: c-myc), or isotype specific control (IP: IgG). HuR-bound myosin IIA was detected by Western blot analysis with an anti-myosin IIA specific antibody. Equal pull-down (input levels) of c-myc was ascertained by reincubating the blot with the same antibody used for IP. ( B ). Blot-overlay assay demonstrating that the hinge region of HuR is not relevant for AngII-induced myosin IIA binding. Pull-down of myosin IIA from vehicle (−) or AngII treated HMC was performed as described in ‘Materials and Methods’ section . Blots were probed with equal amounts of total cell lysates cells overexpressing c-myc-HuR wild-type or c-myc-HuRΔHinge. Myosin IIA-HuR interaction was assessed by reincubating the blot with an anti-c-myc antibody. Equal pull-down of myosin is ascertained by reincubating the blot with the same antibody used for the myosin IIA co-IP. ( C ). HMC were transfected with the indicated c-myc-point mutated HuR and IPs were performed similar as described for (A). Equal pull-down (input levels) of c-myc was ascertained by reincubating the blot with the same antibody used for IP. ( D , left panel). HuR binding to myosin IIA is sensitive toward RNase treatment. HMC overexpressing c-myc-HuRwild-type or c-myc-HuRΔHinge were treated for 2 h with AngII (0.1 µM) before total cell lysates from transfectants were immunoprecipitated with an anti-c-myc antibody or with control IgG. Before the IP reaction, the cell homogenates were subjected to RNase treatment and subsequently immunoblotted with an anti-myosin IIA specific antibody. Equal pull-down of c-myc is ascertained by reincubating the blot with anti-c-myc antiserum. (right panel).

    AngII promotes translocation of PKCδ to the nucleus and induces a physical interaction between PKCδ and nuclear HuR. (A) Indirect immunofluorescence images show PKCδ (green) and HuR (red) proteins in unstimulated cells and cells stimulated for 15 min with AngII (100 nM) as indicated. The merged images show a colocalization of PKCδ and HuR after AngII exposure (yellow signal). Data are representative of two independent experiments giving similar results. (B) Time course of AngII-induced PKCδ entry to the nucleus. Quiescent hMC were treated with either vehicle (−) or with AngII (100 nM) for the indicated time points and then lysed. Fifty micrograms of cytosolic (PKCδ c ) and nuclear (PKCδ n ) extracts was subjected to SDS-PAGE and successively immunoblotted with a phosphorylation-independent PKCδ antibody. To ascertain equal protein contents within the fractions, the blots were stripped and reprobed with an HDAC1-specific or anti-β-actin antibody. The Western blots shown are representative of three independent experiments giving similar results. (C) IP of nuclear PKCδ (PKCδ) and pSer-PKC substrate (pSer) levels in hMC stimulated either without (−) or with (+) 100 nM AngII for 15 min. For IP, a total protein amount (500 μg) of nuclear extracts from differentially treated cells was incubated overnight with 2 μg of either anti-HuR antibody (a.-HuR) or a nonspecific IgG isotype antibody (IgG). Equal amounts of immunoprecipitated HuR were ascertained by stripping the blot and reincubating it with the anti-HuR antibody used for IP. The data shown are representative of three independent experiments giving similar results.

    Figure Lengend Snippet: AngII promotes translocation of PKCδ to the nucleus and induces a physical interaction between PKCδ and nuclear HuR. (A) Indirect immunofluorescence images show PKCδ (green) and HuR (red) proteins in unstimulated cells and cells stimulated for 15 min with AngII (100 nM) as indicated. The merged images show a colocalization of PKCδ and HuR after AngII exposure (yellow signal). Data are representative of two independent experiments giving similar results. (B) Time course of AngII-induced PKCδ entry to the nucleus. Quiescent hMC were treated with either vehicle (−) or with AngII (100 nM) for the indicated time points and then lysed. Fifty micrograms of cytosolic (PKCδ c ) and nuclear (PKCδ n ) extracts was subjected to SDS-PAGE and successively immunoblotted with a phosphorylation-independent PKCδ antibody. To ascertain equal protein contents within the fractions, the blots were stripped and reprobed with an HDAC1-specific or anti-β-actin antibody. The Western blots shown are representative of three independent experiments giving similar results.

    AngII induces the RNA binding of HuR to the UTR of COX-2. hMC were stimulated with vehicle (−) or with 100 nM AngII (+) for 2 h before cells were cross-linked and lysed for IP. HuR-bound mRNA was precipitated by addition of a HuR-specific antibody or, alternatively, the same amount of IgG as a negative control. After elution from Sepharose beads, the isolated RNA samples were analyzed by RT-PCR either by using primer pairs, complementary to sequences encompassing different COX-2 3′ UTR parts (UTR1 and UTR2), or by use of a primer pair complementary to a sequence from the CR as described in Materials and Methods. Input GAPDH levels isolated before the IP were used as a control for equal amounts of input RNA (input) and were assessed by RT-PCR. Furthermore, input HuR levels isolated prior to the IP were used as input protein (input) control. A PCR without RT product was used as a negative control (no RT), whereas COX-2 full-length plasmid used as a template was used as a positive control (cDNA).
