  1. BulletProject: Role of Progesterone Receptor Membrane Component-1 in oogenesis and mammalian fertility (PRO-OVUM)


Infertility is a major problem that affects domestic mammals and declining fertility represents an obstacle in maintaining profitability of dairy farms in Europe and worldwide. Since declining fertility of cattle is mainly due to the poor quality of the oocytes, defining the factors and mechanisms that affect oocyte quality, is essential for improving female fertility. In particular, basic knowledge of which proteins within the oocyte regulate meiosis, oocyte fertilizability and early embryonic development would be advantageous. Based on our preliminary data, we propose that Progesterone Receptor Membrane Component 1 (PGRMC1) is one of the key factors that regulate mammalian oocyte quality. This hypothesis will be rigorously tested by determining 1) whether PGRMC1 plays an essential role in maintaining the ability of bovine oocytes to complete meiosis, undergo fertilization and develop to an healthy embryo in vitro, by genetically manipulating the levels of PGRMC1 within the oocyte, and 2) the PGRMC1 mechanism of action by identifying its interacting proteins within the oocyte.
