Several studies have revealed that the incidence of preeclampsia is high in mothers who carried a fetus with Rubinstein-Taybi Syndrome due to the mutation in CREBBP. We aimed to compare the expression level of the CERBBP gene between preeclamptic and healthy placenta in our study. The expression level of CREBBP gene was evaluated in a total of one hundred placental biopsies from PE patients and healthy pregnant women after delivery using quantitative real-time polymerase chain reaction (qRT-PCR). Moreover, the differential expression of CREBBP was assessed between the maternal and fetal sides of the placenta. Expression of the CREBBP gene was higher in preeclampsia patients compared with the controls (Fold change = 2.158; P = 0.018). Moreover, the gene expression was slightly higher in the fetal side of the placenta, although it was not significantly different (Fold change = 1.713, P = 0.254). Our findings show a role for CREBBP in the pathogenesis of PE. Due to the important role of CREBBP in angiogenesis and hypoxia, the gene may serve as a promising target in future studies.

Method: The study subjects included 250 preeclamptic women and 250 healthy women. The genotyping for rs920778 and rs874945 polymorphisms were performed using the TP-ARMS-PCR method. Results: HOTAIR rs920778 increased the risk of preeclampsia under the dominant and recessive inheritance patterns (OR = 4.84, 95% CI: 3.30-7.10, P < 0.0001; OR = 6.86, 95% CI: 3.51-13.42, P < 0.0001; respectively). Conclusion: This study confirmed the association of HOTAIR rs920778 polymorphism with preeclampsia in Iranian women. Further studies should be performed to confirm our findings.
