A paper on the probable origin of the parasitic horsehair worms' genes that control host mantids' behavior, has been published
For more than 100 years, there have been horrifying observations of terrestrial insects jumping into water right before our eyes all over the world. The mechanism was a complete mystery. Mishina (Special Postdoctoral Researcher), in collaboration with groups of Prof. Sato in Center for Ecological Research, Kyoto University, studies the molecular mechanisms of nematomorph-driven water-entry behavior of mantids, revealing transcriptome changes exclusively in nematomorphs during manipulation. Many possible host-derived genes are identified in nematomorphs that are more frequently up-regulated during manipulation, inferring their roles in the manipulation.

Massive horizontal gene transfer and the evolution of nematomorph-driven behavioral manipulation of mantids.

A paper on epigenetic instability of pluripotent stem cell-derived oocytes has been published
Recent advances in the in vitro culture system enabled generation of mouse oocytes from pluripotent stem cells (ESC and iPSC), while these oocytes presented low developmental competence after fertilization. Aizawa (Scientific Researcher), in collaboration with groups of Prof. Wutz in ETH Zurich, Prof. Peters in Friedrich Miescher Institute for Biomedical Research and others, found instability of transcription regulation during the early oogenesis under the in vitro culture. This instability is presumed to cause the low competence in preimplantation development of pluripotent stem cell-derived oocytes.

Epigenetic regulation limits competence of pluripotent stem cell-derived oocytes.
