| Research Abstract |
In teleost fishes, high amount 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 confirmed that, for the first time, plasma very low density lipoprotein is the major carrier of neutral lipid to oocyte lipid droplets, and updated the model for the oocyte lipidation.
