Proteomic response to heat shock in males and females of a Baikal endemic amphipod Eulimnogammarus cyaneus (Dyb. 1874) (Crustacea: Amphipoda)

Project description:In this project we aimed to establish a proteome-based pipeline for a non-model Baikal endemic amphipod species Eulimnogammarus cyaneus (Dybowsky, 1874). We used next-generation transcriptome sequencing to create a database for protein identification and investigated the proteome of E. cyaneus with LC-MS with particular emphasis on sexual dimorphism and response to acute thermal stress. We were able to characterize ca. 1000 protein groups and found male- and female-specific proteins, as well as proteins specific for thermal stress conditions.

Sexual dimorphism in early osteoclasts demonstrates enhanced inflammatory pathway activation in female cells

Project description:Sexual dimorphism of the skeleton is well documented. At maturity, the male skeleton is typically larger and has a higher bone density than the female skeleton. However, the underlying mechanisms for these differences are not completely understood. In this study, we examined sexual dimorphism in the formation of osteoclasts between cells from female and male mice. We found that the number of osteoclasts in bones was greater in females. Similarly, in vitro osteoclast differentiation was accelerated in female osteoclast precursor (OCP) cells. To further characterize sex differences between female and male osteoclasts, we performed gene expression profiling of cultured, highly purified, murine bone marrow OCPs that had been treated for 3 days with M-CSF and RANKL. We found that 125 genes were differentially regulated in a sex-dependent manner. In addition to genes that are contained on sex chromosomes, transcriptional sexual dimorphism was found to be mediated by genes involved in innate immune and inflammatory response pathways. Furthermore, the NFκB-NFATc1 axis was activated earlier in female early osteoclasts, which partially explains the differences in transcriptomic sexual-dimorphism in these cells. Collectively, these findings identify a sex-dependent intrinsic difference in early osteoclasts, which results from an altered response to osteoclastogenic stimulation. In humans these differences could contribute to the lower peak bone mass and increased risk of osteoporosis that females demonstrate relative to males.

A partially sex-reversed giant kelp sheds light into the mechanisms of sexual differentiation in UV sexual system

Project description:In UV sexual systems, sex is determined during the haploid phase of the life cycle and males have a V chromosome whereas females have a U chromosome. Previous work in the model Ectocarpus revealed that the V chromosome has a dominant role in male sex determination and the female developmental program being a ‘default’ program, triggered in the absence of the male master sex determination gene(s). Here, we describe the identification of a genetically male giant kelp strain presenting phenotypic features typical of a female, despite lacking the U-specific region. The conversion to the female developmental program is however incomplete, because gametes of this feminised male are unable to produce the sperm-attracting pheromone lamoxiren. We identify the transcriptomic pathways underlying the male and female specific developmental programs and show that the phenotypic feminisation of the variant strain is associated with both feminisation and de-masculinisation of gene expression patterns. Importantly, the feminisation phenotype was associated with the dramatic downregulation of two V-specific genes including a candidate sex-determining gene on the V-specific region. Our results reveal the transcriptional changes associated with sexual differentiation in a UV system with extensive sexual dimorphism, disentangling the role of sex-linked genes and autosomal gene expression in the initiation of the male and female developmental programs. Overall, the data presented here imply that the U-specific region in the giant kelp is not required to initiate the female developmental program, but is critical to produce fully functional eggs, arguing against the idea that female is the ‘default’ sex in this species.

Sexually dimorphic gene expression in bovine conceptuses at the initiation of implantation is not reflected in the changes in the endometrial transcriptome.

Project description:In cattle, maternal recognition of pregnancy occurs on Day 16 via secretion of interferon tau (IFNT) by the conceptus. The endometrium can distinguish between embryos with different developmental competencies. In eutherian mammals, X-chromosome inactivation (XCI) is required to ensure an equal transcriptional level of most X-linked genes for both male and female embryos in adult tissues, but this process is markedly different in cattle than mice. We examined how sexual dimorphism affected conceptus gene expression and amino acid composition as well as the endometrial transcriptome during the peri-implantation period of pregnancy. Of the 5132 genes were differently expressed on Day 19 in male compared to female conceptuses, 2.7% were located on the X-chromosome. Concentrations of specific amino acids were higher in the uterine luminal fluid with male compared to female conceptuses, while female conceptuses had higher expression of specific amino acid transporters (SLC6A19 and SLC1A35). Of note, the endometrial transcriptome was not different in cattle gestating a male or a female conceptus. These data support the hypothesis that, far from being a blastocyst specific phenomenon, XCI is incomplete before and during implantation in cattle. Despite differences in gene expression and amino acid utilization in male versus female conceptuses, the sex of the conceptus itself does not elicit a different response in the endometrium.

LC-MS of PBMC in SLE and healthy control

Project description:Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disease that displays a significant gender difference in terms of incidence and severity. However, the underlying mechanisms accounting for sexual dimorphism remain unclear. To reveal the heterogeneity in the pathogenesis of SLE between male and female patients. PBMC were collected from 15 patients with SLE (7 males, 8 females) and 15 age-matched healthy controls (7 males, 8 females) for proteomic analysis. Enrichment analysis of proteomic data revealed that type I interferon signaling and neutrophil activation networks mapped to both male and female SLE, while male SLE has a higher level of neutrophil activation compared with female SLE. Our findings define gender heterogeneity in the pathogenesis of SLE and may facilitate the development of gender-specific treatments.

Single-nucleus RNA-seq of adult female and male mouse livers for sex-biased gene expression analyses

Project description:To obtain new insight into the sexual dimorphism of mammalian livers, single-nucleus RNA-seq was performed on the liver samples from two female and two male adult mice. The single-nucleus libraries were generated on the 10X Chromium Next GEM Single Cell 3ʹ platform and sequenced on Illumina NextSeq 550. We used the data to understand the heterogeneity and sex-biased gene expression of liver cell types. The data revealed significant sex differences primarily focused on hepatocytes. Specifically, from the sex-biased genes detected at the bulk tissue level, we observed that male-biased genes are more highly expressed in male hepatocytes, and female-biased genes are more highly expressed in female hepatocytes.

Sequencing of murine corticotrophs from male and female POMC-GFP mice.

Project description:Stress-related illness represents a major burden on health and society. Understanding the molecular mechanisms underlying stress responses is an important step to understand these diseases, and design treatments. Sexual dimorphism in stress responses have been extensively reported, with depression and most anxiety disorders being more prevalent in women. Corticotrophs of the anterior pituitary play a central role in the generation of hormonal stress responses, by secreting the stress hormone ACTH in response to stressful stimuli. However, their role in contributing to sexually dimorphic responses of the HPA axis is very poorly understood. We performed bulk RNA-sequencing of FACS-sorted corticotrophs from male and female POMC-GFP mice to determine the molecular determinants of sexual dimorphic traits in the activity of these cells, revealing extensive differential gene expression at the transcriptional level. This includes more than 71 mRNAs encoding ion channel subunits, which could be involved in the generation of the sexual dimorphism in their electrical activity.
