The miR-130a and C/EBP-ε expression in ATRA-induced MPRO cells. (A) Expression of miR-130a in differentiated MPRO cells. (B) The expression pattern for Cebpe, Ltf, Camp, and Lcn2 mRNAs in differentiated MPRO cells. The highest value of expression of each mRNA during the 5 days of differentiation was assigned the value 1, and the relative expressions between the other populations were recalculated accordingly. Asterisks indicate significant differences between the peak expression and the other days of differentiation (*P < .05). (C) Immunoblot showing expression of C/EBP-ε protein and β-actin expression in differentiated MPRO cells. Error bars represent standard deviation (SD) of triplicate measurements.
