Examining Sex Differences in the Human Placental Transcriptome During the First Fetal Androgen Peak

ABSTRACT: Sex differences in human placenta exist from early pregnancy to term. However, it is unclear whether these differences are driven solely by sex chromosome complement or are subject to differential sex hormonal regulation. Here, we survey the human chorionic villus (CV) transcriptome for sex-linked signatures from 11 to 16 gestational weeks, corresponding to the first window of increasing testis-derived androgen production in male fetuses.

RNA-seq of the first-trimester decidua for understanding the maintenance of early gestation as well as pathogenesis in pregnancy-related disorders

Project description:Implant failure and insufficient placental development are important causes of female infertility, recurrent miscarriage, and other pregnancy-related problems. A better understanding of gene expression profiling based on high-throughput sequencing technology is important for the study on the development of the placenta and the causes of pregnancy-related diseases. In this study, we collected 6 first-trimester chorionic villus and decidua tissues and obtained the transcriptome database on high-throughput sequencing. We performed routine principal component analysis (PCA) on these 12 samples and identified differentially expressed genes from samples with different sex background. And identified genes highly expressed in villus and decidua, respectively.

High-throughput small RNA sequencing of the human placenta at first and third trimester with fetal sex differences analysis

Project description:Human placenta bulk small RNA-seq from healthy pregnancies without infertility, from n=113 first trimester (58 female, 55 male) and n=47 third trimester (19 female, 28 male) tissue samples. Tissue was collected at Cedars-Sinai Medical Center in Los Angeles, California, USA. First trimester placenta was collected at 70-102 days of gestation from leftover chorionic villus sampling for prenatal genetic diagnosis. Third trimester placenta was collected after delivery at 254-290 days gestation from the fetal side near the umbilical cord insertion site beneath the amnion. Mothers with pre-existing diabetes or hypertension were excluded. All pregnancies were conceived without fertility treatments, were normal karyotype, and resulted in live singleton births. The average parental age was advanced (over 35 years old) but PCA analysis did not show clustering by either maternal or paternal age. Gonzalez et al 2021 [PMID: 34030457] analyzes similarities and differences between first and third trimester miRNA expression overall. Flowers et al 2021 focuses on the effect of fetal sex on miRNA expression across gestation.

Epigenome analysis of first trimester CVS samples from normal and Trisomy 13,18,21 pregnancies, and maternal whole blood samples.

Project description:Genome wide DNA methylation profiling of normal and trisomic placentas, and maternal blood cell DNA. The aim of this study was to search for methylation differences between maternal and fetal(placenta) cell free DNA, and between normal and trisomic placentas for an optimized methylation based noninvasive prenatal diagnosis of fetal chromosomal aberations. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in DNA samples from Chorionic villus samples(CVS) and DNA samples from whole blood. Samples included 12 Maternal blood cell samples from normal pregnancies, 12 normal CVS, 12 Trisomy 21 CVS, 12 trisomy 18 CVS and 6 trisomy 13 CVS samples. Bisulphite converted DNA from the 54 samples were hybridized to the Illumina Infinium 450k Human Methylation Beadchip.

Prevalence of chromosomal alterations in first-trimester spontaneous pregnancy loss

Project description:Extensive genome analysis of pregnancy loss products by genome haplarithmisis. Pregnancy loss (PL) is the primary pregnancy complication, mostly caused by chromosomal abnormalities of the conceptus. However, the nature and prevalence of these abnormalities and the allocation of (ab)normal cells in embryonic and placental compartments during intrauterine development remains elusive. We analyzed 1,745 spontaneous PLs and found that ~50% were karyotypically normal. We applied genome haplarithmisis to 91 PL families with normal karyotypes, following whole-genome genotypes of the parents as well as of the extraembryonic mesoderm (EM) and chorionic villi (CV), representing embryonic and placental cells, of the product of conception (POC), which allowed characterizing genomic landscape of both lineages. 36.4% of these PLs have chromosomal aberrations not previously detected by karyotyping. In contrast to viable pregnancies where mosaic chromosomal abnormalities are often restricted to the CV, we find that in spontaneous abortions, the situation is reversed with a higher degree of mosaic chromosomal imbalances in EM rather than CV.

Investigating Human Placentation and Pregnancy Using First Trimester Chorionic Villi

Project description:<p>Chorionic villus sampling (CVS) is routinely used for prenatal diagnosis of cytogenetic disorders, but also possesses great potential for studying placentation. To better understand villi biology, human placentation, and how these relate to pregnancy outcomes, we examined the morphology and transcriptomes of villi obtained via CVS from 10-14 weeks of pregnancy and correlated these with pregnancy attributes and clinical outcomes.</p>
