Single-cell profiling of healthy human kidney reveals features of sex-based transcriptional programs and tissue-specific immunity

ABSTRACT: We present a single-cell perspective of healthy human kidney from 19 living donors, with equal contribution from males and females, profiling the transcriptome of 27677 high-quality cells to map healthy kidney at high resolution. Our sex-balanced dataset revealed sex-based differences in gene expression within proximal tubular cells, specifically, increased anti-oxidant metallothionein genes in females and the predominance of aerobic metabolism-related genes in males. Using CD45+ enrichment in 10 samples, we profile the immune niche of the kidney, identifying kidney-specific lymphocyte populations with unique transcriptional profiles indicative of kidney-adapted functions. We observed significant heterogeneity in resident myeloid populations and identified an MRC1+ LYVE1+ FOLR2+ C1QC+ population as the predominant myeloid population in healthy kidney. This study provides a broad cellular map of healthy human kidney, revealing novel insights into the complexity of renal parenchymal cells and kidney-resident immune populations.

Sex Diversity in Proximal Tubule and Endothelial Gene Expression in Mice with Ischemic Acute Kidney Injury

Project description:Female sex protects against development of acute kidney injury (AKI). While sex hormones may be involved in protection, the role of differential gene expression is unknown. We conducted gene profiling in male and female mice with or without kidney ischemia-reperfusion injury. Mice underwent bilateral renal pedicle clamping (30 min), and tissues were collected 24 hours after reperfusion. RNA-sequencing was performed on proximal tubules and kidney endothelial cells. Female mice were resistant to ischemic injury compared to males, determined by plasma creatinine, histologic scores, neutrophil infiltration, and extent of apoptosis. Sham mice had sex-specific gene disparities in proximal tubule and endothelium, and male mice showed profound gene dysregulation with ischemia-reperfusion compared to females. After ischemia proximal tubules from females exhibited smaller increases compared to males in injury-associated genes Lcn2, Havcr1, and Krt18, and no upregulation of Sox9 or Krt20. Endothelial upregulation of adhesion molecules and cytokines/chemokines occurred in males, but not females. Upregulated genes in male ischemic proximal tubules were linked to tumor necrosis factor and Toll-like receptor pathways, while female ischemic proximal tubules showed upregulated genes in pathways related to transport. The data suggest that sex-specific gene expression profiles in male and female proximal tubule and endothelium may underlie disparities in susceptibility to AKI.

Gene expression profiling of the olfactory tissues from sex-separated and sex-combined female and male mice

Project description:We sought to investigate the scope of cellular and molecular changes within a mouse’s olfactory system as a function of its exposure to odors emitted from members of the opposite sex. To this end, we housed mice either separated from members of the opposite sex (sex-separated) or together with members of the opposite sex (sex-combined) until six months of age and then profiled transcript levels within the main olfactory epithelium (MOE), vomeronasal organ (VNO), and olfactory bulb (OB) of the mice via RNA-seq. For each tissue type, we then analyzed gene expression differences between sex-separated males and sex-separated females (SM v SF), sex-combined males and sex-combined females (CM v CF), sex-separated females and sex-combined females (SF v CF), and sex-separated males and sex-combined males (SM v CM). Within both the MOE and VNO, we observed significantly more numerous gene expression differences between males and females when mice were sex-separated as compared to sex-combined. Chemoreceptors were highly enriched among the genes differentially expressed between males and females in sex-separated conditions, and these expression differences were found to reflect differences in the abundance of the corresponding sensory neurons.

RNA-seq following knockdown of a sex determing gene in house fly

Project description:We injected double-stranded RNA (dsRNA) into house fly embryos to knock down transformer (Md-tra), creating sex-reversed males that do not carry a Y chromosome. We also injected dsRNA trageting GFP as a sham treatment. We used RNA-seq to compare gene expression in the sex-reversed males with genotypic (normal) females (injected with dsRNA targeting GFP) and two types of genotypic (normal) males (injected with dsRNA targeting Md-tra or GFP). The expression profiles of sex-reversed males were similar to normal males. In contrast, about two thousand genes are differentially expressed between sex-reversed males and normal females, a similar magnitude as between normal males and females.

Sperm Epimutation Biomarkers of Obesity and Pathologies following DDT Induced Epigenetic Transgenerational Inheritance of Disease

Project description:Gestating F0 generational female rats were transiently exposed to DDT during fetal gonadal sex determination and the incidence of adult onset pathologies was assessed in the subsequent F1, F2, and F3 generations. In addition, sperm differential DNA methylation regions (DMRs) that were associated with specific pathologies in the F3 generation males were investigated. No pathology was observed in the F1 generation DDT lineage males or females compared with F1 generation controls (vehicle exposure). There was an increase of testis disease and early onset puberty in the F2 generation DDT lineage males. The F3 generation DDT males had significant increases in testis disease, prostate disease, and late onset puberty. The F3 generation DDT females had significant increases in ovarian and kidney disease. Both the F3 generation males and females had significant increases in the frequency of obesity and multiple disease. The F3 generation sperm was collected to examine DMRs for the ancestrally exposed DDT male population. Unique sets of DMRs were associated with late onset puberty, kidney disease, and multiple disease pathologies.

Population- and sex-biased gene expression in the excretion organs of Drosophila melanogaster

Project description:We used RNA-seq to investigate gene expression variation in Malpighian tubules, which have a function analogous to that of human kidneys. In order to characterize population differentiation, we sequenced the Malpighian tubule transcriptomes of flies derived from two populations, one from sub-Saharan Africa (Zimbabwe) and one from Europe (the Netherlands). Males and females were examined separately. Overall, we found a high amount of differential expression between sexes (2,308 genes) and populations (2,474 genes). Although most of the differentially expressed genes were consistent between sexes and populations, there were 615 genes showed sex-biased expression in only one population and 557 genes showed population-biased expression in only one sex. mRNA expression profiles of Drosophila melanogaster Malpighian tubules from adult males and females from a European and an African population (2 biological replicates per sex and population)

Extensive sex differences at the initiation of meiotic recombination

Project description:Meiotic recombination differs between males and females, however, when and how these differences are established is unknown. We identify extensive sex differences at recombination initiation by mapping hotspots of meiotic DNA double strand breaks in male and female mice. Contrary to past findings in humans, few hotspots are used uniquely in either sex. Instead, grossly different recombination landscapes result from up to 15-fold differences in hotspot use between males and females. Indeed, most recombination occurs at sex-biased hotspots. Sex biased hotspots appear to be partly determined by chromosome structure, and DNA methylation, absent in females at the onset of meiosis, plays a substantial role. Sex differences are also evident later in meiosis as the repair frequency of distal meiotic breaks as crossovers diverges in males and females. Suppression of distal crossovers may help to minimize age-related aneuploidy that arises due to cohesion loss during dictyate arrest in females.

Sex-biased expression in heads of three Drosophila species

Project description:Investigation of sex-biased expression across species have relied on measurements from whole flies which sample the extensive expression differences found in the germline and gonads of females and males. We wanted to examine genes with sex-biased expression in a somatic tissue to analyze patterns of genes with sex-biased expression in the context of a tissue more phenotypically similar between females and males. We used a Nimblegen microarray designed for Drosophila melanogaster and two custom micoarrays designed for D. pseudoobscura and D. mojavensis to survey gene expression differences in heads of females and males.
