Expression level of miR-1468 in pituitary cells of Yanbian yellow cattle. (A) The expression level of miR-1468 in pituitary cells transfected with the mimics (miR-1468-mi group) and mimics reference substance (NC group) of miR-1468. Compared with NC group, the column marked by ** showed significant difference (P<0.01); (B) The expression level of miR-1468 in pituitary cells transfected with the inhibitor (miR-1468-in group) and inhibitor reference substance (iNC group) of miR-1468. U6 was used as an internal reference.
