| Research Abstract |
In teleost fishes, high amounts of lipids and proteins are accumulated in oocytes during their growth phase ; they are later utilized as energy and nutrient resources by developing embryos and larvae. However, little is known about the origin of such lipids and the mechanisms underlying their accumulation into oocytes. In the present study, we aimed to clarify the mechanisms at the molecular levels. As the results, we identified various factors involved in the lipid uptake into fish oocytes, and proposed a new model for the oocyte lipidation.
