Sex-specific transcriptional differences between non-treated male and female human umbilical vein endothelial cells (HUVEC)

ABSTRACT: Significant sex differences exist in cardiovascular diseases. It is largely unknown whether sexually dimorphic gene expression plays a role, and whether cells themselves show intrinsic sex differences. We therefore performed whole genome expression analyses in human umbilical vein endothelial cells (HUVEC) from five sample pools with equal amounts of four individual RNAs from either male or female donors (altogether 20 male and 20 female donors) and compared levels of gene transcription between the sexes. Genes indicative for greater immune responsiveness were stronger expressed in female compared to male HUVEC. There was a significant enrichment of 77 immune-related genes in female HUVEC.

Sex-specific transcriptional differences between male and female human umbilical vein endothelial cells (HUVEC) after shear stress.

Project description:To assess whether there is a sex-specific response to stress, we subjected male and female HUVEC to laminar shear of 6 dyn/cm2 for 24 hours and analysed changes in gene expression. 6.7 % of all mRNAs were regulated by shear stress. Female HUVEC showed a more pronounced transcriptional response to shear than did their male counterparts. In addition to quantitative differences, a number of genes were regulated in the opposite direction between the two sexes by shear stress.

Angiotensin II Increases Oxidative Stress and Inflammation in Female, But Not Male, Endothelial Cells

Project description:To investigate sex differences in endothelial cell response to AngII, male and female human umbilical vein endothelial cells (HUVEC) were treated with AngII for 24 hours. RNA seq was run, and demonstrated that female HUVEC had elevated genes associated with oxidative stress and inflammatory responses compared to male HUVEC following AngII treatment.

Male and female embryonic chicken livers (arnol-affy-chick-445002)

Project description:The study is relevant to an understanding of the forces that lead to sex differences in the brain. Many neural and psychiatric diseases affect men and women differently, so the understanding of sex differences in brain function impacts on our understanding of why the male and female brain differ in their susceptibility to disease. Using Affymetrix chicken arrays, we will measure the gene expression in male and female embryonic chicken liver to compare with previous studies of brain. Gene expression differs in the male and female embryonic chicken liver. Z-linked genes are expressed higher in males than females, in a manner similar to Z-linked genes in the brain. The comparison of brain and liver will demonstrate which sex differences are specific to brain and which are general. 20 male and 20 female chicken embryos will serve as source of brain tissue. In late stage embryos, we will remove the liver and extract total RNA. Four birds will comprise each individual sample. Thus, we will have 5 biologically independent male samples, and an equal number of female samples. Keywords: dose response

Macrophages from sex-reversed chicken embryos [set1]

Project description:To identify markers associated with inherent cellular sex-identity, we analysed cultured macrophages from male and female chick embryos. We found that male and female macrophages respond differently to stimulation by bacterial lipopolysaccharide and that female macrophages constitutively express higher levels of interferon target genes than male macrophages. To determine whether these differences resulted from the actions of gonadal hormones, we induced gonadal sex-reversal to alter the hormonal environment of the developing chick and analysed different tissues and macrophages from male and female embryos.

Male and female embryonic chicken hearts (arnol-affy-chick-445639)

Project description:The study is relevant to an understanding of the forces that lead to sex differences in the brain and other somatic tissues. Many neural and psychiatric diseases affect men and women differently, so the understanding of sex differences in brain function impacts on our understanding of why the male and female brain differ in their susceptibility to disease. Using Affymetrix chicken arrays, we will measure the gene expression in male and female embryonic chicken heart, and compare to previous studies of brain and liver. Gene expression differs in the male and female embryonic chicken heart, liver, and brain. Higher expression of Z-chromosome genes in males is found in heart, liver and brain. Comparison of heart and brain will reveal brain-specific patterns of sex differences, and patterns that apply to multiple tissues. 20 male and 20 female chicken embryos will serve as source of heart tissue. In late stage embryos, we will remove the tissue and extract total RNA. Four birds will comprise each individual sample. Thus, we will have 5 biologically independent male samples, and an equal number of female samples. Keywords: dose response

Transcriptomics revealed sex differences in human pulmonary microvascular endothelial cells in normoxia and hypoxia

Project description:To investigate sex differences at the transcriptome level in human pulmonary microvascular endothelial cells (HPMECs) from healthy male and female donors basally (in normoxia) and in hypoxic conditions. RNA-seq was performed on male (n=3) and female (n=4) HPMECs that were cultured in conditions of physiological shear stress (PMID: 36730645) in normoxia (21% O2) or in hypoxia (1% O2) for either 24 or 48 hours.

Transcriptome analysis of HUVEC

Project description:Human umbilical vein endothelial cells (HUVEC) were isolated from umbilical cords from four different donors, as previously described (Cooke et al., 1993). Cells were maintained in Medium 199 (M199, Invitrogen) containing 20% fetal calf serum, 28g/ml gentamycin, 2.5g/ml amphotericin B, 1ng/ml epidermal growth factor and 1g/ml hydrocortisone (all from Sigma) for 48 hours prior to processing. HUVEC cultures isolated using this method were 96-98% pure, determined by positive staining by flow cytometry of CD105, CD31 and vWF and the expression of elevated levels of intracellular adhesion molecule (ICAM-1) and E-selectin following stimulation with the inflammatory cytokine interleukin-1. Total HUVEC RNA was isolated using the RNeasy mini kit with QIAshredder (Qiagen) according to the manufacturers instructions. RNA integrity number was >8.0 for all samples.

Influence of Sex on Gene Expression in Human Corneal Epithelial Cells

Project description:Objectives. Sex-associated differences have been identified in the anatomy, physiology and pathophysiology of the human cornea. We hypothesize that many of these differences are due to fundamental variations in gene expression. Our objective in this study was to determine whether such differences do exist in human corneal epithelial cells both in vivo and in vitro. Methods. Human corneal epithelial cells were isolated from the corneoscleral rims of male and female donors. Cells were processed either directly for RNA extraction, or first cultured in phenol red-free keratinocyte serum free media. The RNA samples were examined for differentially expressed mRNAs by using of CodeLink Bioarrays and Affymetrix GeneChips. Data were analyzed with GeneSifter.Net software. Results. Our results demonstrate that sex significantly influences the expression of over 400 genes in human corneal epithelial cells in vivo. These genes are involved a broad spectrum of biological processes, molecular functions and cellular components, such as metabolic processes, DNA replication, cell migration, RNA binding, oxidoreductase activity and nucleoli. We also identified significant, sex-related effects on gene expression in human corneal epithelial cells in vitro. However, with few exceptions (e.g. X- and Y-linked genes), these sex-related differences in gene expression in vitro were typically different than those in vivo. Conclusions. Our findings support our hypothesis that sex-related differences exist in the gene expression of human corneal epithelial cells. Keywords: Female vesus Male.
