Area of Science:

  • Aquatic Biotechnology
  • Vertebrate Developmental Biology
  • Molecular Biology

Background:

  • Genetic manipulation of fish is crucial for advancing aquatic biotechnology and understanding vertebrate development.
  • Fish eggs are ideal for genetic engineering due to their numerous, large, and transparent nature, facilitating the production of transgenic animals.
  • Effective genetic engineering relies on the development of suitable expression vectors.

Purpose of the Study:

  • To develop novel, efficient "all-fish" expression vectors for genetic engineering in fish.
  • To create expression vectors incorporating regulatory elements from carp beta-actin and salmon growth hormone genes.
  • To test the functionality of these vectors in various biological systems.

Main Methods:

  • Development of two fish expression vectors, FV-1 and FV-2, utilizing carp beta-actin promoter/enhancer and salmon growth hormone polyadenylation signal.

    • Main Results:

    • Successful development of two functional "all-fish" expression vectors, FV-1 and FV-2.
    • Demonstrated utility of the vectors in microinjected fish eggs and cultured cells.
    • Vectors have been successfully applied in the creation of transgenic fish with growth-enhancing genes.

    Conclusions:

    • The developed FV-1 and FV-2 expression vectors are effective tools for fish genetic engineering.
    • These vectors provide a valuable resource for advancing research in aquatic biotechnology and developmental biology.
    • The successful use in transgenic fish highlights their potential for future applications in aquaculture and research.
