Abstract
Wnt signalni put igra važnu ulogu u razvoju placente i diferencijaciji ljudskog trofoblasta, a Dishevelled proteini su njegovi centralni medijatori koji omogućuju finu regulaciju aktivnosti ovog signalnog puta. Prema dosadašnjim spoznajama neuspješna invazija trofoblasta zapažena je u posteljicama fetusa sa zastojem u rastu (IUGR) i u hipertenzivnim poremećajima. Budući da Dishevelled proteini djeluju kao pozitivni regulatori Wnt signalnog puta, cilj ovog rada bio je ispitati ekspresiju DVL1, DVL2, DVL3 proteina u terminskim posteljicama sa zastojem u rastu (IUGR). Analizirane su ukupno 24 terminske posteljice od kojih je 15 bilo iz trudnoća sa zastojem u rastu, a 9 iz urednih trudnoća koje su služile kao kontrola. Napravljena je imunohistokemijska analiza sva tri antigena, a rezultati su kvantificirani stereološkom varijablom volumenske gustoće (Vv, mm0). Statistički značajno manja ekspresija proteina DVL1, DVL2 I DVL3 detektirana je u terminskim posteljicama sa zastojem u rastu ploda u odnosu na zdrave terminske posteljice (p<0,05; Mann Whitney) . Dobiveni rezultati ukazuju na važnost porodice Dishevelled proteina u razvoju IUGR-a te podržavaju hipotezu plitke invazije u nastanku ove patologije trudnoće.
Abstract (english)
Wnt signaling pathway plays an important role in the development of the placenta and the differentiaton of trophoblast. Dishevelled proteins are the central mediators in this pathway which enable its fine regulation. According to previous knowledge, unsuccessfull trophoblast invasion has been noticed in placentas of fetuses with intrauterine growth restriction (IUGR) and hypertensive disorders. Since Dishevelled proteins act as positive regulators of the Wnt signaling pathway, the aim of this study was to examine the expression of DVL1, DVL2 and DVL3 proteins in term placentas with IUGR. 24 term placentas have been analysed of which 15 were those from pregnancies with IUGR and 9 from normal pregnancies which served as a controle. Immunohistochemical analysis was done on all three antigens and the results stereologically quantified using a variable for volume density (Vv, mm0). Statistically significant lower expression of proteins DVL1, DVL2 and DVL3 was detected in term placentas with IUGR in comparison to healthy term placentas (p<0,05; Mann Whitney). The results show the importance of Dishevelled proteins in the formation of IUGR and support the hypothesis of shallow invasion being a factor in the pathogenesis of this condition
