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.
