Expression profiles of miRNAs in THP-1 cells from different groups. (A) Sample correlation analysis. (B) DE-miRNA distribution of MTB-1458-6 hpi (MTB-1458-6 hpi vs. uninfected-6 hpi), BCG-6 hpi (BCG-6 hpi vs. uninfected-6 hpi), MTB-1458-24 hpi (MTB-1458-24 hpi vs. uninfected-24 hpi), and BCG-24 hpi (BCG-24 hpi vs. uninfected-24 hpi). (C) Venn diagram of BCG-6-U (upregulated miRNAs from BCG-6 hpi vs. uninfected-6 hpi), BCG-24-U (upregulated miRNAs from BCG-24 hpi vs. uninfected-24 hpi), MTB-6-U (upregulated miRNAs from MTB-1458-6 hpi vs. uninfected-6 hpi), MTB-6-D (downregulated miRNAs from MTB-1458-6 hpi vs. uninfected-6 hpi), MTB-24-U (upregulated miRNAs from MTB-1458-24 hpi vs. uninfected-24 hpi), and MTB-24-D (downregulated miRNAs from MTB-1458-24 hpi vs. uninfected-24 hpi).
