Levels of mature miR103a (A, D, G), miR141 (B, E, H), and miR200a (C, F, I) expression were determined in EPEC infected Caco-2 cells, mouse jejunum and colon as detailed in “Methods”. Data are mean ± SE of at least triplicate determinations using different passages of Caco-2 cells or tissue from multiple mice. ** P < 0.05; * P < 0.01.
