MicroRNA; Non-invasive prenatal diagnosis; Preeclampsia

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 ... more

Leptin; Leptin receptor; Polymorphism; Preeclampsia

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 ... more

ACE; Insertion/deletion polymorphism; Preeclampsia

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 ... more

Gestational hypertension; LIPC gene; Lipid metabolism; Preeclampsia; SNP

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- ... more

GSTM1; GSTT1; Preeclampsia

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 ... more

Gene expression; Partial least squares; Preeclampsia

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 ... more

Preeclampsia; rs7579169; Single nucleotide polymorphism

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 ... more

Epigenetics; High-resolution melting; Imprinted genes; Methylation; Polymerase chain reaction

High-resolution melting (HRM) is considered an inexpensive, rapid, and attractive methodology for methylation analysis. In the application of the polymerase chain reaction (PCR) to methylation analysis, amplification efficiencies are biased towards unmethylated, rather than methylated, templates: a phenomenon known as PCR bias. To overcome PCR bias, primers that include CpG site(s) and ... more

Amur tiger; Gene expression profiling; ITL-2; PEG10; PLAC8; Placenta

The Amur tiger is a unique endangered species in the world, and thus, protection of its genetic resources is extremely important. In this study, an Amur tiger placenta cDNA library was constructed using the SMART cDNA Library Construction kit. A total of 508 colonies were sequenced, in which 205 (76%) genes were annotated and mapped to 74 KEGG pathways, including 29 metabolism, 29 genetic ... more
