FIGURE 2.

Alterations of miR-29a and miR-29b expression levels in cells from the murine hepatoma IAR20 cells (A and B) and primarily cultured normal mouse hepatocytes (C and D) stimulated with E₂ or TGF-β1. A and C, enhancement of miR-29a and miR-29b expression levels in IAR20 cells (A) and primarily cultured normal murine hepatocytes (C) by E₂. B and D, reduction of miR-29a and miR-29b expression levels in IAR20 cells (B) and murine hepatocytes (D) by TGF-β1. The data are presented as mean ± S.E. for three independent experiments. *, p < 0.05; **, p < 0.01.
