    a Glutathione S-transferase (GST) or GST-FLAG-PR100 (GF-PR)-bound glutathione beads were mixed with ( + ) or without (−) NSC-34 cell lysates. After the rotation at 4 °C for 5 h, the glutathione beads were washed and were subjected to 5–20% gradient gel SDS–PAGE followed by immunoblotting (IB) using indicated antibodies. In western blotting using anti-GST antibody, the large smear within the molecular weights ranging 25–46 kDa in the GF-PR lane is thought to consist of C-terminal truncated GST-FLAG-PR100 proteins. A band located around 50 kDa in the GST lane is thought to represent dimerized and/or aggregated GST-derived proteins. b NSC-34 cells overexpressing EGFP-FLAG-PR100 (EGFP-F-PR100) (green) together with HA-tagged hnRNPF, hnRNPH1, or hnRNPM were fixed and were immunostained with HA (red). Nuclei were stained with 4′,6-diamidino-2-phenylindole (DAPI, blue). Scale bar = 10 μm. The rightmost panel shows the profile image of fluorescence intensities on the lines of EGFP-FLAG-PR100 and hnRNPs-merged image. Arrows and arrowheads indicate the localization of nucleoplasm-localizing EGFP-FLAG-PR100 and the border of nucleolus-localizing EGFP-FLAG-PR100, respectively. c Lysates of NSC-34 cells overexpressing HA-tagged hnRNPF, hnRNPH1, or hnRNPM and GST or GST-FLAG-PR100 (GF-PR)-bound glutathione beads were incubated with ( + ) or without (−) 20 μg/mL RNase A. After the incubation, cell lysates were mixed with GST or GST-FLAG-PR100-bound glutathione beads. The glutathione beads were washed and were subjected to immunoblotting (IB) using indicated antibodies. d , e NSC-34 cells were transfected with the empty vector or the FLAG-PR100-encoding vector. At 48 h after the transfection, the cell lysates were immunoprecipitated (IP) with normal mouse IgG1 (Cont.) or the FLAG antibody. Precipitates were then used for RNA immunoprecipitation (RIP) assay ( d ) and dot blotting analysis with the FLAG antibody ( e ). Reverse transcription (RT) (−) was used as negative control to monitor the PCR amplification from genomic DNA. f NSC-34 cells overexpressing EGFP or EGFP-FLAG-PR100 (green) were fixed and stained with the 500 nM Quasar 570-labeled <t>NEAT1</t> Stellaris probe (red). Nuclei were stained with DAPI (blue). Scale bar = 10 μm. Arrowheads and arrow correspond to paraspeckles. The rightmost panel shows the profile image of fluorescence intensities on the lines of EGFP-FLAG-PR100 and NEAT1-merged image in magnified image. Arrowhead and arrow indicate the co-localization of NEAT1 with nucleoplasm-localizing EGFP-FLAG-PR100 and the nucleolus-localizing EGFP-FLAG-PR100, respectively

The glutathione beads were washed and were subjected to immunoblotting (IB) using indicated antibodies. c NSC-34 cells overexpressing EGFP-FLAG-PR100 (EGFP-F-PR100) (green) were fixed and were immunostained with TDP-43 antibody (red). Nuclei were stained with DAPI (blue). Scale bar = 10 μm. The rightmost panel shows the profile image of fluorescence intensities on the line of EGFP-FLAG-PR100 and TDP-43-merged image. Arrows and arrowheads indicate the localization of nucleoplasm-localizing EGFP-FLAG-PR100 and the border of nucleolus-localizing EGFP-FLAG-PR100, respectively. d , e NSC-34 cells were infected with adenovirus encoding LacZ or TDP-43 at an MOI of 800. At 48 h after the infection, the quantitative real-time PCR analysis of NEAT1 was performed ( d ). The cell lysates were subjected to immunoblotting (IB) using indicated antibodies ( e ). The data are presented as means ± SD ( N = 3). Statistical analysis was performed by the unpaired t-test. f NSC-34 cells were transfected with the NEAT1 -promoter (+) or NEAT1 -promoterless (−) luciferase vector together with the pEF1-Myc/His-vec (−) or the pEF1-TDP-43 (+). At 48 h after the transfection, the luciferase activity was measured. The data are presented as means ± SD ( N = 3). Statistical analysis was performed by one-way ANOVA followed by the Tukey’s multi comparisons test. g – i NSC-34 cells were infected with adenovirus encoding LacZ or TDP-43 derivatives at an MOI of 800. At 48 h after the infection, the cell viability was detected by WST-8 assay ( g ). The cell lysates were subjected to immunoblotting (IB) using indicated antibodies ( h ). CTF35, C-terminal fragment 35 kDa. The quantitative real-time PCR analysis of NEAT1 was performed ( i ). The data are presented as means ± SD ( N = 3). Statistical analysis for ( g ) was performed by one-way ANOVA followed by the Tukey’s multi comparisons test. Statistical analysis for ( i ) was conducted by one-way ANOVA followed by the Dunnett’s multi comparisons test

    a, b NSC-34 cells were transfected with the 5 nM control siRNA (−) or the TDP-43 siRNA (+). At 18 h after the transfection, cells were infected with adenovirus encoding LacZ (−) or FLAG-PR100 (+) at an MOI of 400. At 48 h after the infection, the quantitative real-time PCR analysis of NEAT1 was performed ( a ). The cell lysates were subjected to immunoblotting (IB) and dot blotting analysis using indicated antibodies ( b ). The data are presented as means ± SD ( N = 3). Statistical analysis was performed by one-way ANOVA followed by the Tukey’s multi comparisons test. c , d NSC-34 cells were infected with adenovirus encoding LacZ (−) or TDP-43 (+) at an MOI of 400. Cells were also co-infected with adenovirus encoding LacZ (−) or FLAG-PR100 (+) at an MOI of 200. At 48 h after the infection, the quantitative real-time PCR analysis of NEAT1 was performed ( c ). The cell lysates were subjected to immunoblotting (IB) and dot blotting analysis using indicated antibodies ( d ). The data are presented as means ± SD ( N = 3). Statistical analysis was performed by one-way ANOVA followed by the Tukey’s multi comparisons test
