There was a significant rise in the level of properdin and significant decline in the level of FH at both mRNA and protein levels in the placentae and umbilical cord of PE compared to N; in GDM placentae, both properdin and FH were significantly elevated compared to N. In the case of RPL placentae, similar to PE, properdin expression was high while FH expression level was low. The gene discussed is CFP; the disease is gestational diabetes.
