ABSTRACT
In the present study, we examined the insulin-like growth factor receptor 1(IGF-1R) transcription using real-time PCR at different stages of oocytes of Russian sturgeon (Acipenser gueldenstaedtii) at age 8-9 years and weight 25 kg that were grown under aquaculture conditions. Compare to the pre-vitellogenesis stage, the transcription of IGF-1R increased at the vitellogenesis stages (yellow, gray and black). The mRNA of IGF-1R of oocytes in the black stage is significantly higher than in the gray or yellow stages. However, there are no significant differences between the gray or yellow stages of the mRNA level. Based on previous studies and the result of the mRNA of IGF-1R of oocytes during oogenesis, we proposed a model for the effect of GH, IGF-1 and IGF-1R on the oogenesis of Russian sturgeon, which is a very important process for creating caviar.
