Transferrin Identification in Sterlet (Acipenser ruthenus) Reproductive System [PDF]

Animals, 2019
Transferrins are a superfamily of iron-binding proteins and are recognized as multifunctional proteins. In the present study, transcriptomic and proteomic methods were used to identify transferrins in the reproductive organs and sperm of out-of-spawning ...

Efficient Gene Transfer and Gene Editing in Sterlet (Acipenser ruthenus) [PDF]

Frontiers in Genetics, 2018
The sturgeon (Acipenseriformes) is an important farmed species because of its economical value. However, neither gene transfer nor gene editing techniques have been established in sturgeon for molecular breeding and gene functional study until now.

Identification and characterization of hybrids of Acipenser ruthenus and Acipenser baerii (Actinopterygii, Acipenseriformes) from the Irtysh River [PDF]

Acta Biologica Sibirica, 2021
Two sturgeon species, Acipenser ruthenus (Linnaeus, 1758) and Acipenser baerii (Brandt, 1869), inhabit the Irtysh basin. In 2018, we received some “atypical” specimens of sturgeon, which were similar to A. ruthenus but had a number of pronounced external

Disturbances in the ploidy level in the gynogenetic sterlet Acipenser ruthenus. [PDF]

J Appl Genet, 2017
Artificial mitotic gynogenesis, a chromosome set manipulation, is applied to provide the homozygous progeny with only maternal inheritance. Here, gynogenetic development was induced in the sterlet Acipenser ruthenus L. (Acipenseridae) by activation of the eggs originating from albino females with the UV-irradiated spermatozoa from wild-coloured males ...

Fluorescent emission profiles reveal interspecific differences in three Danube River Basin sturgeon species [PDF]

Scientific Reports
Biofluorescence is widespread among marine teleosts but has not been reported in sturgeons (Acipenseridae). This exploratory study investigates interspecific differences in fluorescent emission profiles among three Danube River Basin sturgeon species ...

Immunohistochemical mapping of thymic microenvironment in sterlet (Acipenser ruthenus) [PDF]

Veterinární Medicína, 2020
In this study, we describe the immunohistochemical characterisation of the thymus, the main lymphoid organ, in sturgeon. The wide range cytokeratin, vimentin, S-100 protein, LCA (CD45) and CD3 were selected as the immunohistochemical markers to map the ...

Effects of 11-Ketotestosterone on Development of the Previtellogenic Ovary in the Sterlet, Acipenser ruthenus. [PDF]

Front Endocrinol (Lausanne), 2020
11-ketotestosterone (11-KT) is a non-aromatizable and the most potent androgen in a few teleost. It has been reported that 11-KT in serum had a high concentration and increased sharply before the period of yolk deposition in females of few fishes. The aim of this study was to analyze the role of 11-KT both in vivo and in vitro on ovarian development ...

Chemical induction of haploid gynogenesis in sterlet Acipenser ruthenus [PDF]

Czech Journal of Animal Science, 2014
Chromosomal manipulations in sturgeons, particularly gynogenesis, are interesting due to the potential to change female ratio in progeny that can be useful for caviar production.

Draft Genome and Complete Hox-Cluster Characterization of the Sterlet (Acipenser ruthenus). [PDF]

Front Genet, 2019
Background: Sturgeons (Chondrostei: Acipenseridae) are a group of "living fossil" fishes at a basal position among Actinopteri. They have raised great public interest due to their special evolutionary position, species conservation challenges, as well as their highly-prized eggs (caviar).

Standardization of egg activation and fertilization in sterlet (Acipenser ruthenus)

Aquaculture Reports, 2020
This study was conducted to determine the minimum number of spermatozoa and optimal volume of activation water for effective fertilization of sterlet Acipenser ruthenus eggs.
