Preeclampsia

Common variant rs7579169 is associated with preeclampsia in Han Chinese women

L. F. Guo, Wang, Z. H., Wang, Y. F., Guo, L. F., Wang, Z. H., and Wang, Y. F., Common variant rs7579169 is associated with preeclampsia in Han Chinese women, vol. 15, p. -, 2016.

As a heterogeneous group of disorders in pregnancy, many genetic factors are involved in the development of preeclampsia. The single nucleotide polymorphism (SNP) rs7579169, located on chromosome 2q14.2, has been shown to be associated with pregnancy-induced hypertension in Europeans. In this study, we examined whether the SNP rs7579169 is associated with the susceptibility to preeclampsia through a case-control research model in Han Chinese women. Genotypes of 145 patients with preeclampsia and 150 healthy pregnant subjects were identified by direct sequencing.

Partial least squares-based gene expression analysis in preeclampsia

F. Jiang, Yang, Y., Li, J., Li, W., Luo, Y., Li, Y., Zhao, H., Wang, X., Yin, G., and Wu, G., Partial least squares-based gene expression analysis in preeclampsia, vol. 14, pp. 6598-6604, 2015.

Preeclampsia is major cause of maternal and fetal morbidity and mortality. Currently, the etiology of preeclampsia is unclear. In this study, we investigated differences in gene expression between preeclampsia patients and controls using partial least squares-based analysis, which is more suitable than routine analysis. Expression profile data were downloaded from the Gene Expression Omnibus database. A total of 503 genes were found to be differentially expressed, including 248 downregulated genes and 255 overexpressed genes.

Polymorphisms in the GSTT1 and GSTM1 genes are associated with increased risk of preeclampsia in the Mexican mestizo population

A. Sandoval-Carrillo, Aguilar-Duran, M., Vázquez-Alaniz, F., Castellanos-Juárez, F. X., Barraza-Salas, M., Sierra-Campos, E., Téllez-Valencia, A., La Llave-León, O., and Salas-Pacheco, J. M., Polymorphisms in the GSTT1 and GSTM1 genes are associated with increased risk of preeclampsia in the Mexican mestizo population, vol. 13, pp. 2160-2165, 2014.

Preeclampsia is a pregnancy-specific disorder in humans and a major cause of maternal and neonatal morbidity and mortality. Increasing evidence suggests that oxidative stress plays an important role in the pathogenesis of preeclampsia. The aim of this study was to investigate the relationship between null alleles of the glutathione S-transferases (GST) M1 and T1 genes and the risk of preeclampsia. This case-control study involved 112 preeclamptic and 233 normoevolutive pregnant women. The null polymorphisms were genotyped by multiplex polymerase chain reaction (PCR).

Variants -250G/A and -514C/T in the LIPC gene are associated with hypertensive disorders of pregnancy in Chinese women

H. Lin, Yin, Z., Yu, X. Y., Lin, N., Lin, Y., Chen, J., Chen, Y. Z., Lu, K. P., and Liu, H. K., Variants -250G/A and -514C/T in the LIPC gene are associated with hypertensive disorders of pregnancy in Chinese women, vol. 13, pp. 6126-6134, 2014.

We examined the influence of the promoter polymorphisms -250G/A (rs2070895) and -514C/T (rs1800588) in the human hepatic lipase (LIPC) gene on dyslipidemia and hypertensive disorders complicating pregnancy (HDCP) in a Chinese population. Clinically defined HDCP patients (N = 321) and healthy pregnant women (N = 331) were recruited and genotyped using polymerase chain reaction-restriction fragment length polymorphism for the two LIPC single nucleotide polymorphisms (SNPs).

Expression and significance of the imprinted gene PEG10 in placenta of patients with preeclampsia

X. Y. Liang, Chen, X., Jin, Y. Z., Chen, X. O., and Chen, Q. Z., Expression and significance of the imprinted gene PEG10 in placenta of patients with preeclampsia, vol. 13, pp. 10607-10614, 2014.

The aim of this study was to investigate the expression and significance of the imprinted gene PEG10 (paternally expressed gene 10) in preeclampsia placental tissue. Quantitative real-time reverse transcriptase polymerase chain reaction and immunohistochemistry to evaluate mRNA and protein expression and distribution of PEG10 in placental tissues obtained from 22 preeclampsia patients (8 patients with mild preeclampsia, 14 cases of severe preeclampsia). At the same time, 22 cases of normal pregnant women served as controls.

Meta analysis of angiotensin-converting enzyme I/D polymorphism as a risk factor for preeclampsia in Chinese women

W. G. Zhong, Wang, Y., Zhu, H., and Zhao, X., Meta analysis of angiotensin-converting enzyme I/D polymorphism as a risk factor for preeclampsia in Chinese women, vol. 11, pp. 2268-2276, 2012.

Preeclampsia affects 3-8% of pregnancies and is a major cause of maternal and perinatal morbidity and mortality worldwide. Inappropriate activation of the renin-angiotensin system may play a role in the development of preeclampsia. An insertion/deletion polymorphism in the angiotensin-converting enzyme gene (ACE-I/D) has been associated with differences in ACE activity. However, there are controversies in reports on the association of ACE-I/D with preeclampsia.

High leptin level and leptin receptor Lys656Asn variant are risk factors for preeclampsia

S. Wang, Qiao, F. Y., and Feng, L., High leptin level and leptin receptor Lys656Asn variant are risk factors for preeclampsia, vol. 12, pp. 2416-2422, 2013.

The aim of this study was to investigate the relationship between the leptin receptor (LEPR) polymorphism/serum leptin level and preeclampsia. The prevalence of a single nucleotide polymorphism in the LEPR gene exon 14 at -656 and the serum leptin concentrations in 97 preeclamptic pregnant mothers were compared to those of 110 healthy controls. The Lys656Asn genotype and Lys656Asn + Asn656Asn frequencies in the LEPR gene were significantly more prevalent in preeclampsia mothers than in controls (P

Serum microRNA expression in pregnancies with preeclampsia

T. Gunel, Zeybek, Y. G., Akçakaya, P., Kalelioglu, I., Benian, A., Ermis, H., and Aydinli, K., Serum microRNA expression in pregnancies with preeclampsia, vol. 10, pp. 4034-4040, 2011.

Preeclampsia continues to be a mortal disease of pregnant women throughout the world. Recently, geneticists, allied with obstetricians, have opened new frontiers. MicroRNAs (miRNAs) are members of a class of small, noncoding RNA molecules. They are critical posttranscriptional regulators of gene expression. We extracted circulating miRNA from maternal plasma and quantified mir-152 and mir-210.
