Effects of miR-181a mimics and inhibitors on IL1a and IL1b mRNA levels in LPS-induced Raw264.7 (A) and PMA/LPS-induced THP-1 cells (B); effects of miR-181a mimics and inhibitors on ILa, IL1b, IL6, and TNFa in cell lysates and media of LPS-induced Raw264.7 (C and E) and PMA/LPS-induced THP-1 cells (D and F) assayed by ELISA.

<p>Data are expressed as mean ± SD (n = 3), **<i>P</i><0.01 vs. negative control (NC), ^#<i>P</i><0.05, ^##<i>P</i><0.01 vs. miRNA inhibitor negative control (NC-i). ‘NC-i’ is a single stranded nucleic acid used as negative control for miR-181a inhibitors (181a–i). ‘LPS + or −’, cells were treated with or without LPS in the case of Raw264.7 cells or PMA/LPS in the case of THP-1 cells.
