Transcription of Insulin-like Growth Factor Receptor in Russian Sturgeon (Acipenser gueldenstaedtii) Ovary during Oogenesis
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, gra...
متن کاملAnatomical, hormonal and histological descriptions of captive Russian sturgeon (Acipenser gueldenstaedtii) with intersex gonads.
Sturgeons are known throughout the world as the source of black caviar. Their declining populations in their native habitats, mainly the Caspian Sea, due to over-fishing for meat and caviar production, destruction of their spawning grounds and water pollution, have led to their introduction into aquaculture in areas with suitable conditions, including Israel. Recently, we noticed an unusual phe...

Acipensins – Novel Antimicrobial Peptides from Leukocytes of the Russian Sturgeon Acipenser gueldenstaedtii
Antimicrobial peptides (AMPs) play an important role in the innate defense mechanisms in humans and animals. We have isolated and studied a set of antimicrobial peptides from leukocytes of the Russian sturgeon Acipenser gueldenstaedtii belonging to a subclass of chondrosteans, an ancient group of bony fish. Structural analysis of the isolated peptides, designated as acipensins (Ac), revealed in...
متن کاملFormation and structure of egg envelopes in Russian sturgeon Acipenser gueldenstaedtii (Acipenseriformes: Acipenseridae).
The covering of the eggs in Russian sturgeon Acipenser gueldenstaedtii consists of three envelopes (the vitelline envelope, chorion and extrachorion) and is equipped with multiple micropyles. The most proximal to the oocyte is the vitelline envelope that consists of four layers of filamentous and trabecular material. The structural components of this envelope are synthesized by the oocyte (prim...
