Sex-specific changes in gene expression in response to estrogen pollution around the onset of sex differentiation in grayling (Salmonidae)

The synthetic 17 alpha-ethinylestradiol (EE2) is a common estrogenic pollutant that has been suspected to affect the demography of river-dwelling salmonids. One possibility is that exposure to EE2 tips the balance during initial steps of sex differentiatio ...

Drosophila melanogaster cloak their eggs with pheromones, which prevents cannibalism

Yury Tsybin, Laure Menin, Konstantin Nagornov

Oviparous animals across many taxa have evolved diverse strategies that deter egg predation, providing valuable tests of how natural selection mitigates direct fitness loss. Communal egg laying in nonsocial species minimizes egg predation. However, in cann ...

Role of Cnot6l in maternal mRNA turnover

Radek Jankele

Removal of poly(A) tail is an important mechanism controlling eukaryotic mRNA turnover. The major eukaryotic deadenylase complex CCR4-NOT contains two deadenylase components, CCR4 and CAF1, for which mammalian CCR4 is encoded by Cnot6 or Cnot6l paralogs. W ...

Maternal allocation of carotenoids increases tolerance to bacterial infection in brown trout

Laure Menin, Matay Hobil

Life-history theory predicts that iteroparous females allocate their resources differently among different breeding seasons depending on their residual reproductive value. In iteroparous salmonids there is typically much variation in egg size, egg number, ...

Effects of ploidy and sex-locus genotype on gene expression patterns in the fire ant Solenopsis invicta

Chitsanu Khurewathanakul, Oksana Riba Grognuz, Laurent Keller

Males in many animal species differ greatly from females in morphology, physiology and behaviour. Ants, bees and wasps have a haplodiploid mechanism of sex determination whereby unfertilized eggs become males while fertilized eggs become females. However, ...

Vertical transmission of a Drosophila endosymbiont via cooption of the yolk transport and internalization machinery

Bruno Lemaitre, Fanny Schüpfer, Juan Camilo Paredes Escobar, Jeremy Keith Herren

Spiroplasma is a diverse bacterial clade that includes many vertically transmitted insect endosymbionts, including Spiroplasma poulsonii, a natural endosymbiont of Drosophila melanogaster. These bacteria persist in the hemolymph of their adult host and exh ...

Expansion of a VE-Cadherin+CD45+ population in the yolk sac upon Etv2 overexpression in the mouse embryo - Effects of BMP and Wnt signaling inhibition on the differentiation of a Flk1+ extraembryonic mesoderm in vitro model

Matteo Pluchinotta

The difficulty to find compatible donors for bone marrow transplantation makes the need for an alternative source of HSCs urgent. HSC derived from patient-specific iPS cells are ideal candidates for this purpose. Nevertheless, although HSCs are the best ch ...

Essential role of endothelial Notch1 in angiogenesis

Freddy Radtke

BACKGROUND: Notch signaling influences binary cell fate decisions in a variety of tissues. The Notch1 receptor is widely expressed during embryogenesis and is essential for embryonic development. Loss of global Notch1 function results in early embryonic le ...
