XBP1 and preeclampsia: Combining the two methods we identified, it is well known preeclampsia related genes like: FLT1, LEP, INHA, ENG, PROCR, MMP1, XBP1 and FSTL3. However, other genes as FLNB, INHBA, BCL6, TPBG, NDRG1, LYN and QSOX1 were also significant in our analysis, but this has been little explored or is unknown in the current state of the art of preeclampsia pathophysiology.
