Figure Lengend Snippet: Differentially expressed miRNA in exosomes from tuberculous pleural effusion and transudative pleural effusion (as control) by miRNAs sequencing. A Heatmap of differential exosomes miRNAs expression in pleural effusion between control individuals and tuberculous pleurisy patients; n = 9. RPKM values are represented by gradient colors and shown for each sample. Red represents a higher RPKM; blue represents a lower RPKM. Results are based on nine RNA sequencing samples. B Venn diagram showing the overlap between differentially expressed miRNAs in TPE exosomes and transudate exosomes. C Volcanic map of differential exosomes miRNAs expression in pleural effusion between control individuals and tuberculous pleurisy patients. Adjusted P value < 0.05 and fold change > 1 was set as restrictive conditions to identify the differentially expressed genes. D Pathway enrichment analysis showed the significant target genes of differentially expressed miRNAs associated with various KEGG pathways. E The expression of three differentially expressed miRNAs in TPE exosomes and transudate exosomes was verified by RT-qPCR and normalized by the U6. Data are expressed as mean ± SEM. n = 6, **** P < 0.0001 (Paired student’s t-test)

Figure Lengend Snippet: miR-503-5p regulated Smurf1/Smad7 signaling pathway. A , B Venn diagram showing overlap between differentially up-regulated miRNAs in TPE exosomes and miRNAs targeting Smurf1 or Smad7 predicted by the miRTarBase. The online analysis database “miRTarBase” ( https://miRTarBase.cuhk.edu.cn/ ) was used. C Human PMCs were transfected with miR-503-5p mimics (50 nmol/ml) or negative control (NC) for 24 h, after which miR-503-5p expression levels in cells were determined by qRT-PCR and normalized by the U6. D - E Human PMCs were transfected with miR-25-3p mimics or miR-503-5p mimics or miR-92a-3p mimics (50 nmol/ml) or negative control (NC) for 24 h, after which intracellular mRNA levels of Smurf1 were measured by RT-qPCR and normalized to GAPDH ( D ). The protein expression of Smurf1 and TGF-β receptor (TGFBR) were detected by western blotting. Bar graphs revealed changes in relative ratio of Smurf1 and TGFBR to GAPDH. F Human PMCs were transfected with miR-503-5p mimics (50 nmol/ml) or negative control (NC) for 24 h, after which mRNA expression of Smurf1, TGFBR and COL1A1 were detected by qRT-PCR. G Human PMCs were incubated with miR-503-5p mimics. After 24 h, Smurf1 protein was detected by immunofluorescence staining and nuclei with DAPI staining. Bar scale: 50 μm. H - K Human PMCs were transfected with miR-503-5p mimics (50 nmol/ml) or negative control (NC) for 24 h. miR-503-5p expression levels in cells were determined by qRT-PCR and normalized by the U6 ( H ). The protein expression of S Smurf1, TGFBR and COL1A1 were detected by western blotting ( I ). Bar graphs revealed changes in the relative ratio to GAPDH ( J ). mRNA levels of S Smurf1, TGFBR and COL1A1 were measured by RT-qPCR and normalized to GAPDH ( K ). Data are mean ± SEM. n = 3. * P < 0.05 (student’s t-test)

Figure Lengend Snippet: Triple miRNAs inhibitor attenuated TPE-Exo induced pleural fibrosis. C57BL/6 mice were intra-pleural injected by using PBS (100 µl/mouse), TPE-Exo (100 µl/mouse), TPE-Exo plus control inhibitor, or TPE-Exo plus triple miRNAs inhibitor with carbon particles (0.1 mg/mouse) as descriptions in the Methods. TPE-Exo from 50 ml TPE was administered at days 1, 5, 9. In TPE-Exo plus triple miRNAs inhibitor group, TPE-Exo was co-incubated with triple miRNAs inhibitor which restrained expressions of miR-150-3p, miR-424-3p and miR-503-5p. All mice were euthanized at day 21, and tissues were taken for analysis.

doi: 10.2169/internalmedicine.6047-25

Figure Lengend Snippet: Results of a microarray analysis. Eight miRNAs were significantly downregulated in the patients with functional dyspepsia (FD) compared to those in healthy controls using method 1. However, six miRNAs were downregulated using method 2. Notably, five miRNAs were consistently downregulated between the two methods. Furthermore, five miRNAs and seven miRNAs were significantly upregulated using methods 1 and 2, respectively. Therefore, four miRNAs were consistently upregulated in patients with FD.
