Figure Lengend Snippet: ( A ) Flow cytometric histogram and MFI analysis of DiI fluorescence from LNPs after coculture with LGG for 6 hours. ( B ) Flow cytometric histogram of FAM fluorescence from miRNA and MFI of FAM fluorescence from miRNA after coculture with LGG for 6 hours. ( C ) Confocal laser scan microscope image of uptake by LGG after coculture for 6 hours. Fluorescence intensity traces (orange line) from the left images were plotted at the right using ImageJ software. ( D ) Flow cytometric histogram and MFI analysis of DiI fluorescence from LNPs after coculture with E. coli (EcN) for 6 hours. ( E ) Flow cytometric histogram of FAM fluorescence from miRNA and MFI analysis of FAM fluorescence from miRNA after coculture with EcN for 6 hours. ( F ) Confocal laser scan microscope image of uptake by EcN after coculture for 6 hours. Fluorescence intensity traces (orange line) from the left images were plotted at the right using ImageJ software. ( G ) The putative binding sites of mdo-miR7267-3p in the monooxygenase ycnE mRNA. ( H ) Quantitative polymerase chain reaction (qPCR) analysis of ycnE expression in LGG treated with mdo-miR7267-3p formulations. ( I ) The pathway of miRNA regulation of indole-3-carboxaldehyde (I3A) production. ( J ) I3A level after cocultured with various mdo-miR7267-3p formulations. Data in (A), (B), (D), (E), (H), and (J) are expressed as means ± SD ( n = 3 biologically independent samples) and representative of two independent experiments. Statistical significance was assessed using one-way ANOVA with Tukey’s multiple comparisons post hoc test, giving P values: * P < 0.05 and *** P < 0.001. PE, phycoerythrin; 5′UTR, 5′ untranslated region; a.u., arbitrary units.
