RÉSUMÉ

To examine expression profile of magnesium responsive genes (MRGs) in placentas of normoevolutive and preeclamptic women. The expression profiles of MRGs were determined in placentas of normoevolutive (N=26) and preeclamptic (N=25) women by RT-qPCR. Among all tested MRGs (9) only SLC41A1 (encoding for Na(+)/Mg(2+) exchanger) was significantly overexpressed in ~54.2% of preeclamptic (n=24) and in ~9.5% of normoevolutive (n=21) specimens. On average, SLC41A1 was overexpressed sixfold in the preeclamptic group. Presence of SLC41A1 in placentas was confirmed by Western blot analysis. CONCLUSION. SLC41A1 is significantly overexpressed in nearly 55% of preeclamptic placentas. This may indicate a direct contribution of changed Mg homeostasis in the development of preeclampsia.
