A permutation test showed that BCL6 overexpression in ischemia mimicked overall expression changes of module M1 and M2 genes in preterm preeclampsia, while ARNT2 overexpression in ischemia (and also in hypoxia) mimicked the up-regulation of module M2 genes in term and preterm preeclampsia (Data S11 in Supplementary Material). The gene discussed is ARNT2; the disease is preeclampsia.
