TGFB1 and preeclampsia: Finally, during functional enrichment analysis, on the one hand, we confirmed two signalling pathways that emerged during the search for specific targets: MAPK and Insulin signalling pathway [59,60,61,62,63]; on the other hand, we have shed light on two other extremely interesting signalling pathways for preeclampsia: TGF-β and VEGF [67,68].
