Increased serum iron levels in pregnant women with preeclampsia: a meta-analysis of observational studies.

Our study aimed to investigate whether the serum iron levels in patients with preeclampsia were higher than in healthy pregnant women and to evaluate potential heterogeneities. We searched Pubmed, Embase, Web of Science and Medline databases for studies before September 2016. The standardised mean difference (SMD) and 95% confidence interval (CI) were used to combine results across the studies, in addition to the random-effect model.

Tetra-primer ARMS-PCR identified four pivotal genetic variations in bovine PNPLA3 gene and its expression patterns.

Patatin-like phospholipase domain-containing protein 3 (PNPLA3), a member of the patatin like phospholipase domain-containing (PNPLA) family, plays an important role in energy balance, fat metabolism regulation, glucose metabolism and fatty liver disease. Tetra-primer amplification refractory mutation system PCR (T-ARMS-PCR) is a new method offering fast detection and extreme simplicity at a negligible cost for SNP genotyping. In this paper, we investigated the genetic variations at different ages of 660 Chinese indigenous cattle belonging to three breeds (QC, NY, JX) and applied T-ARMS-PCR and PCR-RFLP methods to genotype four SNPs, SNP1: g.

Haplotypes in the promoter region of the CIDEC gene associated with growth traits in Nanyang cattle.

Cell death-inducing DFFA-like effector c (CIDEC, also known as Fsp27) has emerged as an important regulator of metabolism associated with lipodystrophy, diabetes, and hepatic steatosis. It is required for unilocular lipid droplet formation and optimal energy storage. The mechanism between this gene and livestock growth traits, however, has yet to be reported.

Tetra-primer ARMS-PCR identifies the novel genetic variations of bovine HNF-4α gene associating with growth traits.

Hepatocyte nuclear factor-4α (HNF-4α), a member of the hepatocyte nuclear factor family, plays an important role in regulating the expression of genes involved in the development, differentiation and normal function of liver and pancreatic β cells, as well as the maintenance of glucose homeostasis. Tetra-primer amplification refractory mutation system PCR (T-ARMS-PCR) is a new method offering fast detection and extreme simplicity at a negligible cost for SNP genotyping. In this paper, we characterize the polymorphisms of the bovine HNF-4α gene in three Chinese indigenous cattle breeds (n=660).

Transcription factor ZBED6 mediates IGF2 gene expression by regulating promoter activity and DNA methylation in myoblasts.

Zinc finger, BED-type containing 6 (ZBED6) is an important transcription factor in placental mammals, affecting development, cell proliferation and growth. In this study, we found that the expression of the ZBED6 and IGF2 were upregulated during C2C12 differentiation. The IGF2 expression levels were negatively associated with the methylation status in beef cattle (P < 0.

Expression, SNP identification, linkage disequilibrium, and haplotype association analysis of the growth suppressor gene ZBED6 in Qinchuan beef cattle.

Zinc finger, BED-type containing 6 (ZBED6) is a novel transcription factor that was identified and shown to act as a repressor of IGF2 transcription in skeletal muscle myogenesis and development. The aims of this study were to determine ZBED6 expression level and examine the association of the ZBED6 polymorphism with growth traits in Qinchuan beef cattle. The bovine ZBED6 mRNA was detected in eight tissues by quantitative real-time PCR (qPCR), being highly expressed in skeletal muscle.

A 5'-regulatory region and two coding region polymorphisms modulate promoter activity and gene expression of the growth suppressor gene ZBED6 in cattle.

Zinc finger, BED-type containing 6 (ZBED6) is an important transcription factor in placental mammals, affecting development, cell proliferation and growth. Polymorphisms in its promoter and coding regions are likely to impact ZBED6 transcription and growth traits. In this study, rapid amplification of 5' cDNA ends (5'-RACE) analysis revealed two transcription start sites (TSS) for the bovine ZBED6 starting within exon 1 of the ZC3H11A gene (TSS-1) and upstream of the translation start codon of the ZBED6 gene (TSS-2).

Intragenic DNA methylation status down-regulates bovine IGF2 gene expression in different developmental stages.

DNA methylation is a key epigenetic modification in mammals and has an essential and important role in muscle development. Insulin-like growth factor 2 (IGF2) is a fetal growth and differentiation factor that plays an important role in muscle growth and in myoblast proliferation and differentiation. The aim of this study was to evaluate the expression of IGF2 and the methylation pattern on the differentially methylated region (DMR) of the last exon of IGF2 in six tissues with two different developmental stages.

Comparative analysis of the IGF2 and ZBED6 gene variants and haplotypes reveals significant effect of growth traits in cattle.

Muscle growth is a complex phenomenon regulated by many factors, whereby net growth results from the combined action of synthesis and turnover. Insulin-like growth factor 2 (IGF2) is a fetal growth and differentiation factor that plays an important role in muscle growth and in myoblast proliferation and differentiation; Zinc finger, BED-type containing 6 (ZBED6) is a novel transcription factor that was identified and shown to act as a repressor of IGF2 transcription in skeletal muscle. In this study, a total of seven single nucleotide polymorphisms (SNPs) were identified, four SNPs in intron 8 of IGF2 and one promoter SNP and two missense mutations in the coding region of ZBED6, two of which were in complete linkage disequilibrium (LD) in the bovine IGF2.

A novel c.-274C>G polymorphism in bovine SIRT1 gene contributes to diminished promoter activity and is associated with increased body size.

SIRT1, a mammalian homologue for yeast silent information regulator 2 (SIR2), is a NAD(+) -dependent deacetylase that belongs to the class III histone deacetylases. It plays an important role in diverse cellular processes, including stress resistance, mitochondrial function, suppression of inflammation and DNA repair. In this study, we screened and identified a novel polymorphism (c.

Relationship of polymorphisms within ZBED6 gene and growth traits in beef cattle.

ZBED6 is a novel transcription factor that was identified and shown to act as a repressor of IGF2 transcription in skeletal muscle. The aim of this study was to examine the association of the ZBED6 polymorphism with growth traits in beef cattle breed. Three single nucleotide polymorphisms (SNPs) were identified in the bovine ZBED6 by sequencing pooled DNA samples (Pool-Seq) and forced polymerase chain reaction-restriction fragment length polymorphism (Forced PCR-RFLP) methods.
