Figure 5A. H9c2 cells treated with tunicamycin (2 µg/ml, 12h) showed significantly lower survival when endogenous Nox4 was silenced (siNox4) as compared to cells treated with a scrambled siRNA (siCtl). Cell survival was restored by treatment with either guanabenz (Gbz, 5 µM) or salubrinal (Sal, 50 µM) but was unaffected by clonidine (Cld, 5 µM). n=3/group. B. Nox4-depleted cells had lower levels of phospho-eIF2α and ATF4 than control cells but these were restored in the presence of guanabenz (Gbz). C. Schematic representation of the effect of Nox4 and the small molecule inhibitors, guanabenz and salubrinal, on the GADD34/PP1/eIF2 interaction. D. Hearts from Nox4 knockout (KO) mice and WT controls were subjected to global ischemia followed by aerobic reperfusion (I/R). Infarct size assessed by triphenyltetrazolium chloride (TTC) staining was greater in Nox4 KO hearts compared to WT and was significantly reduced by guanabenz (Gbz). In the representative heart sections shown at the top, white denotes infarct area and red the viable area. Scale bars, 1 mm. Numbers of hearts are indicated within the bars. E. Immunoblotting of heart homogenates after I/R showed lower levels of phospho-eIF2a, ATF4 and ER chaperones, and higher levels of cleaved caspase-12, in Nox4 KO compared to WT. Tubulin was used as a loading control. Treatment with guanabenz (Gbz) reversed these changes (blots shown to the right).

Phosphorylation of GSK-3 serine-9 is the principal mechanism for regulating its activity; serine-9 phosphorylation inhibits GSK-3 activity. Bar chart shows relative levels of GSK-3β serine-9 phosphorylation following quantification of signals from immunoblots and normalization to total GSK-3β signals. Data were analysed by one-way ANOVA and Tukey's post hoc test. N=4, error bars are s.e.m; *p<0.05. (B) immunoblots of total and serine-9 phosphorylated GSK-3 in spinal cords from three 10 week-old FUS transgenic mice and their non-transgenic littermates. Samples were probed for tubulin as a loading control. Bar chart shows relative levels of GSK-3β serine-9 phosphorylation following quantification of signals from immunoblots and normalization to total GSK-3β signals. Data were analysed by unpaired t-test, error bars are s.e.m.; *p<0.05. (C) cytosolic FUS activates GSK-3 more potently than wild type FUS. Cells were transfected with EGFP control, EGFP-FUS or EGFP-FUS lacking its C-terminal nuclear localization signal (FUSC). Samples were probed on immunoblots for total GSK-3, GSK-3 phosphorylated on serine-9, FUS (using EGFP antibody) and tubulin as a loading control. Bar chart shows relative levels of GSK-3β serine-9 phosphorylation following quantification of signals from immunoblots and normalization to total GSK-3β signals. Data were analysed by one-way ANOVA and Tukey's post hoc test. N=3, error bars are s.e.m.; **p<0.01, ***p<0.001. (D) cytosolic FUS reduces the VAPB-PTPIP51 interaction more potently than wild type FUS. Cells were transfected with PTPIP51-HA and either EGFP control, EGFP-FUS or EGFP-FUSC. PTPIP51 was immunoprecipitated using the HA tag and bound endogenous VAPB detected by immunoblotting. Both inputs and immunoprecipitations (IP) are shown. FUS was detected using EGFP antibody. Bar chart shows relative levels of VAPB bound to PTPIP51 in the immunoprecipitations following quantification of signals from immunoblots. VAPB signals were normalized to immunoprecipitated PTPIP51-HA signals.
Figure 7A. Impact of RNA secondary structures on RNA decay rates (kobs) of 256 different RNA substrates subjected to E.coli RNase R (ecoRNaseR)- or Drosophila melanogaster Dis3l2 (dmDis3l2)-directed RNA decay assay as described in Fig. 2. RNA secondary structures were determined by RNAfold (Gruber et al, 2008) and reported as effective free energy (EFE). Error bars represent SEM of curve fit. Grey boxes represent tukey boxplot of individual EFE groups. White line indicates median. P-Value determined by Mann-Whitney test comparing individual EFE groups against all substrates. Unstructured RNA used for subsequent analysis are indicated (EFE groups 4 to 6). B. Nucleotide content of randomized 3′ end sequence among the indicated number of substrate RNAs, ranked according to decay kinetics from slow (left) to fast (right). Fold-change in abundance for individual nucleotides is reported (bottom). Only unstructured RNA substrates (see A) were considered. C. Decay rate of the indicated number of sequences, grouped according to individual nucleotide content in the randomized 3′ end sequence. Data is represented as boxplot, outliers are not shown. P-Value reports significant differences compared to all substrates as determined by Mann-Whitney test. Grey area represents the inner quartile range and white line the median of all substrates. D. RNaseII/R enzymes act as conserved molecular 'readers' of destabilizing post-transcriptional modifications. In prokaryotes, e.g. E. coli, structured RNA is marked by a polyA-polymerase (PAPase) for subsequent degradation by RNaseR, 3′-to-5′ exoribonuclease with intrinsic preference for 3′ adenylated RNA. In eukaryotes, e.g. flies or mammals, structured RNA undergoes 3′ terminal uridylation by a terminal uridylyltransferase (TUTase) for subsequent degradation by Dis3l2, a 3′-to-5′ exoribonuclease with intrinsic preference for 3′ uridylated RNA.

Subcellular localization of NeoR and NucNeoR and T cell recognition of NeoR‐ and NucNeoR‐expressing cells.Figure 1Subcellular localization of NeoR and NucNeoR and T cell recognition of NeoR‐ and NucNeoR‐expressing cells. RCC1.24 cells were transfected with the NeoR (A) and NucNeoR (B) expression constructs. After 2 days, the subcellular localization of the proteins was analyzed by immunofluorescence using the anti c‐myc antibody 9E10. While NeoR was evenly distributed in nucleus and cytoplasm (a), NucNeoR was confined to the cell nucleus (b). Daylight photographs of the stained cells are shown in (a') and (b'). (C) NeoR‐ and NucNeoR‐transfected RCC1.24 cells were treated with 100 U/mL IFN‐γ for 48 h to induce MHC class II expression. Subsequently, the cells were washed and co‐cultured with the CD4 clone 20‐4/A4, which recognizes a peptide derived from NeoR on HLA‐DP3. GM‐CSF secretion by the T cells was measured 20 h later by ELISA. Both transfectants were recognized after IFN‐γ treatment, indicating that directing NeoR into the cell nucleus does not abrogate antigen presentation. (D) LCL1.11 cells were transfected with NeoR or NucNeoR expression plasmids and antigen presentation was assessed 48 h later with the NeoR‐specific T cell clone 20‐4/A4. Antigen‐transfected LCL1.11 cells were recognized irrespectively of NeoR localization, while untransfected cells or cells transfected with a GFP‐expressing control plasmid were not recognized.
