Expression levels of microRNAs in pregnant (A) and virgin rats (B) in liver tissue according to the dietary treatment during 12 days.

<p>Data is expressed as fold change (mean ±SD) relative to SO diet group. SO diet, 1; OO diet, 2; FO diet, 3; LO diet, 4; PO diet, 5. Different letters in the same graph means statistical difference (P < 0.05) between dietary groups. Animals per group, in (A) n = 4. In (B): SO (n = 6), OO (n = 7), FO (n = 7), LO (n = 5) and PO (n = 6).
