Project description:Transcriptional profiling of hdac1 mutant zebrafish in comparison to their sibling embryos. Embryos resulting from a cross between heterozygous hdac1 mutant zebrafish (hi1618/+) where cultured together then mutants separated from the siblings one the basis of phenotype and RNA extracted from the two groups at 27hpf was compared in a two-colour hybridisation. Two-condition experiment, hdac1 mutants vs. sibling. Biological replicates: 2 (separate mating) Technical replicates: 4 (2 of which are dye-swap)

Project description:Fertility depends, in part, on interactions between male and female reproductive proteins inside the female reproductive tract (FRT) that mediate postmating changes in female behavior, morphology, and physiology. Coevolution between interacting proteins within species may drive reproductive incompatibilities between species, yet the mechanisms underlying postmating-prezygotic isolating barriers remain poorly resolved. Here, we used quantitative proteomics in sibling Drosophila species to investigate the molecular composition of the FRT environment and its role in mediating species-specific postmating responses. We found that (1) FRT proteomes in D. simulans and D. mauritiana virgin females express unique combinations of secreted proteins and are enriched for distinct functional categories, (2) mating induces substantial changes to the FRT proteome in D. mauritiana but not in D. simulans, and (3) the D. simulans FRT proteome exhibits limited postmating changes irrespective of whether females mate with conspecific or heterospecific males, suggesting an active female role in mediating reproductive interactions. Our study suggests that divergence in the FRT extracellular environment and postmating response contribute to previously described patterns of postmating-prezygotic isolation and the maintenance of species boundaries.

Project description:Small regulatory RNAs (sRNAs) of Shigella dysenteriae and other pathogens are vital for the regulation of virulence-associated genes and processes. Here, we characterize RyfA1, one member of a sibling pair of sRNAs produced by S. dysenteriae. Unlike its nearly identical sibling molecule RyfA2, predicted to be encoded almost exclusively by non-pathogenic species, the presence of a gene encoding RyfA1, or a RyfA1-like molecule, is strongly correlated with virulence in a variety of enteropathogens. In S. dysenteriae, the over production of RyfA1 negatively impacts the virulence-associated process of cell-to-cell spread and the expression of ompC, a gene encoding a major outer membrane protein important for the pathogenesis of Shigella. Interestingly, the production of RyfA1 is controlled by a second sRNA, here termed RyfB1; the first incidence of one regulatory small RNA controlling another in S. dysenteriae or any Shigella species.

Project description:Hepatocytes generated from human induced pluripotent stem cells (hiPSCs) are unprecedented resources for pharmaceuticals and cell therapy. However, little attention has so far been paid to variations among hiPSC lines in terms of their hepatic differentiation. We developed an improved hepatic differentiation protocol and compared multiple hiPSC lines. This comparison indicated that the hepatic differentiation propensity varies among sibling hiPSC clones derived from the same adult human dermal fibroblasts (aHDFs). In addition, hiPSC clones derived from peripheral blood cells (PB-iPSCs) consistently showed good hepatic differentiation efficiency, whereas many hiPSC clones from adult dermal fibroblasts (aHDF-iPSCs) showed poor hepatic differentiation. However, when we compared hiPSCs from blood and dermal fibroblasts from the same individuals, we found that variations in hepatic differentiation were largely attributable to donor differences, rather than to the types of the original cells. In order to understand the molecular mechanisms underlying the observed variations in hepatic differentiation, we performed microarray analyses of sibling aHDF-iPSC clones, and aHDF- and PB-iPSC clones from the same individuals. sibling aHDF-iPSC clones (201B6 and 201B7; derived from the same aHDFs) (1) undifferentiated state (n=4, biological replicate #1-#4) (2) CXCR4-positive cell populations sorted by flowcytometry after 7 days of endodermal differentiation (n=4, biological replicate #1-#4) (3) CXCR4-negative cell populations sorted by flowcytometry after 7 days of endodermal differentiation (n=4, biological replicate #1-#4)

Project description:This case shows similarities with 2 previously reported cases, including intraventricular location, histologic appearance (pushing borders, oligodendrocyte-like morphology, rich vascular network) and immunophenotype with co-expression of OLIG2, GFAP and synaptophysin. The onset in an infant, the presence of a high-grade component and the leptomeningeal dissemination, however, have not been previously reported in EWSR1-PATZ1 rearranged tumors, expanding the clinico-pathological spectrum.
