    The in vitro stimulation of lung <t>epithelial</t> cells, macrophages, and neutrophil-precursor cells. Depicted are flow cytometric analyses showing CD69+ ( a – c )- and TLR4+ ( d – f )-stimulated <t>A549,</t> THP1 and HL60 cells. The activation of the NF-kB pathway was detected via a Western blot in all three cell lines, showing the comparison of the NF-kB p50 band in unstimulated and stimulated cells at 50 kDa. YY1 is used as an endogenous control for nuclear protein expression ( g – i ). Further, IL-8 protein expression levels were measured by a cytometric bead array (CBA) after cytokine mix (CM4, CM6, and CM8) stimulation in A549 ( j ) and in HL60 cells ( l ), as well as after M1 differentiation in THP1 cells ( k ).

    Analysis of miRNA expression in stimulated cell lines. Volcano plots illustrate differentially expressed miRNAs measured by next generation sequencing (NGS) in CM8-stimulated A549 cells ( a ), M1 THP1 cells ( b ), and CM8-stimulated HL60 cells ( c ) compared to unstimulated or M0 THP1 cells, respectively ( n = 4). Green dots represent significantly upregulated miRNAs (log2 fold change (FC) > 1; padj < 0.001) and red dots represent significant downregulation of miRNA expression (log2 FC < −1; padj < 0.001). Vertical dotted lines in the volcano plots demonstrate the thresholds of fold changes for further analyses. Venn blot analysis (Venny 2.1) shows comparison of significantly upregulated miRNAs with padj < 0.001 and log2 FC > 1 in stimulated A549, THP1, and HL60 cells ( d ).

    Effects of miRNA transfection on IL-8 mRNA and protein expression. Stimulated A549, THP1, and HL60 cells were transfected with mimics and inhibitors of miR-146a-5p ( a – f ) and miR-146a-3p ( g – l ). IL-8 mRNA expression was measured by qPCR in CM8-stimulated A549 cells ( a , g ), in M1 THP1 cells ( b , h ), and in CM8-stimulated HL60 cells ( c , i ).

    Target analysis of miR-146a-5p and miR-146a-3p. In silico target analysis was performed using www.mirnet.ca showing 203 targets of miR-146a-5p and 116 targets of miR-146a-3p including three overlapping targets. KEGG pathway analysis demonstrates 15 targets implicated in Toll-like receptor signaling (yellow), eight genes involved in RIG-I-like receptor signaling (green), and 12 targets belonging to chemokine signaling pathway (orange) ( a ). Targets that are allocated to multiple pathways are shown as increased dots. Pathways found in the KEGG pathway analysis and their respective padj values are displayed in ( b ) with relevant pathways colored in red. Effects of target modulation by miR-146a-5p mimic and anti-miR-146a-5p transfection were measured individually and in combination in stimulated A549 cells. qPCR measurements show expression of IRAK1 ( c ), TRAF6 ( d ), DDX3X ( e ), RNF125 ( f ), and CXCR4 ( g ) in transfected cells. n = 3. * p < 0.05, ** p < 0.01, **** p < 0.0001.
