CDKN1C and fetal growth restriction: Together with the above-mentioned findings, the fact that our results report decreased Kcnq1ot1 only in PN1, but not E20, IUGR rats as well as no correlation between Kcnq1ot1 and Cdkn1c expression in any of the groups, at any timepoint, suggests that changes in lncRNA Kcnq1ot1 expression alone is not sufficient to explain changes in Cdkn1c in IUGR rat kidneys.
