Fides Zenk

from Wolfsburg, Germany
IMPRS fellow since October 2014 in Iovino lab
Research InterestsDuring fertilization two terminally differentiated cells – sperm and oocyte – fuse to give rise to a totipotent zygote. To achieve totipotency the maternal and paternal genomes have to be reprogrammed to a ground state. During the subsequent developmental stages that lead to pluripotency and multipotency, the zygotic chromatin undergoes de novo establishment of different histone modifications that are associated with loss of cell potency and preparation for the zygotic genome activation (ZGA).
Although, epigenetic reprogramming to the ground state is considered to be a requirement to establish totipotency, recent reports suggest that to some extent some histone modifications are resistant to reprogramming and are inherited through the germline by the early embryo.
My PhD project focuses on the investigation of intergenerational epigenetic inheritance and its role in regulating the early embryonic development of Drosophila.PublicationsMetzger E, Stepputtis SS, Strietz J, Preca BT, Urban S, Willmann D, Allen A, Zenk F, Iovino N, Bronsert P, Proske A, Follo M, Boerries M, Stickeler E, Xu J, Wallace MB, Stafford JA, Kanouni T, Maurer J, Schüle R (2017).
