Project description:To elucidate the function of NANOS2 to regulate the transcriptome in embryonic male germ cells, we performed expression microarray analysis of the embyornic gonads of the Nanos2+/-, Nanos2-/- male and wild type female from E12.5 to E15.5. The Nanos2+/- and Nanos2-/- female gonads at E15.5 were analyzed as a negative control.

Project description:Single cell transcriptomic analyses are increasingly being employed to study human developmental processes in the gonad to advance our understanding of human gametogenesis. However, to date, these analyses have primarily focused on germ cells, while the somatic niche has been largely overlooked. Moreover, a comparative transcriptomic analysis of both female and male early gonad development on the single cell level is currently lacking. We performed single cell RNA-Seq on whole human fetal gonads from first and second trimester, both from male and female. We define gene expression profiles, which include novel marker genes, of major gonadal somatic cell types and validate them on the protein level. We identify the genetic signature of early human male rete cells, both in male and in female gonads. Overall, our study provides an in-depth molecular characterization of both male and female somatic cell types in early fetal gonads.

Project description:Deposition of intramuscular adipose tissue (IMAT; marbling) is one of the primary determinants for beef quality grade within the U.S. However, IMAT accumulation is often secondary to subcuta-neous (SCAT) and visceral (VIAT) adipose tissue deposition, which results in lower product yield. The mechanisms that underlie the differences in the accumulation of IMAT, SCAT, and VIAT are still not fully understood. The aim of this study was to define the depot-specific transcriptome and adipocyte function in IMAT, SCAT and VIAT in beef cattle. Functional transcriptome analysis in-dicated the activation of pathways for greater lipid accumulation and immune function in VIAT and SCAT compared with IMAT. Florescent activated cell sorting analysis identified a greater percentage of adipocyte stem and progenitor cells (ASPC) within IMAT compared to SCAT and VIAT, but lower ASPC's proliferation in vitro, suggesting potential functional defects on IMAT's adipogenic capacity. In vitro culture of adipocytes revealed greater lipid accumulation and insulin responses, and lower lipolysis of SCAT compared to IMAT adipocytes, with VIAT adipocytes having a characteristic of both SCAT, and IMAT adipocytes. Our findings revealed the de-pot-specific transcriptional profile of IMAT, SCAT and VIAT in beef cattle, which were corrobo-rated by differences on adipocyte metabolic function in vitro.

Project description:Background The Pacific oyster Crassostrea gigas (Mollusca, Lophotrochozoa) is an alternative and irregular protandrous hermaphrodite. Little is known about the genetic and phenotypic bases of sex determinism in oysters, and little more about the molecular pathways regulating reproduction. We have recently developed and validated a microarray containing 31,918 oligomers (Dheilly et al., 2011) representing the oyster transcriptome. The application of this microarray to the study of mollusks gametogenesis should provide a better understanding of the key factors involved in sex differentiation and the regulation of oyster reproduction. Results Expression of the 31,918 ESTs was studied in gonads of oysters cultured along the French Atlantic coasts over a yearly reproductive cycle. Principal component analysis and hierarchical clustering first showed a significant divergence in gene expression patterns of males and females beginning when gonial mitosis started. Early expressed male-specific genes included bindin and female-specific genes included foxL2, a pancreatic lipase related protein, cd63 and vitellogenin. ANOVA analysis of the data further revealed 2482 genes differentially expressed during the course of males and/or females gametogenesis. The expression of 434 genes could be localized in either germ cells or somatic cells of the gonad by comparing the transcriptome of gonads to the transcriptomes of striped oocytes and somatic tissues. Analysis of the annotated genes revealed conserved molecular mechanisms between mollusks and mammals. Genes involved in chromatin condensation, DNA replication and repair, mitosis and meiosis regulation, transcription, translation and apoptosis were expressed in both male and female gonads. Additional lists of genes more specifically involved in either spermatogenesis (meiotic phase, in spermatozoids and mature sperm formation and in flagella structure and movement) or oogenesis (female sex differentiation, transcriptional regulation, cell cycle regulation and oocytes maturation) were also generated. Conclusions Our study provides novel insight into spermatogenesis and oogenesis in an alternative hermaphrodite bivalve, the Pacific oyster C. gigas. We identified genes opening new perspectives for functional studies of the signaling pathways implicated in gonad differentiation and development. Individual gonad oysters were sampled in 3 sites: site 1 = Locmariaquer (Brittany, France), site 2 = Baie des Veys (Normandy, France), and site 3 = Argenton (Brittany, France). 8 undifferentiated stage 0 gonads from site 1 were processed. 4 individuals from site 1 were processed for each gonad developmental stage and sex: stage 1 male, stage 1 female, stage 2 male, stage 2 female, stage 3 male, and stage 3 female. Pools of stage 3 females were prepared with individuals from site 1 and site 2 for biological validation of the results. Striped gonads from stage 3 females were prepared for prediction of gene expression localization.
