rS100A8/A9 may promote the transfer of miR-21-5p from platelets to the circulation via MRP4 in DAMI cells Stimulation of DAMI cells with rS100A8/A9 significantly decreased intracellular miR-21-5p levels at 1 hour ( P = .020) and 3 hours ( P = .009), compared with baseline (0 hour; Figure 6 A), with a nonsignificant trend for an increase of miR-21-5p levels in the supernatant at 12 hours ( P = .098; Figure 6 D).
