Area of Science:

  • Virology
  • Molecular Biology
  • Genetic Engineering

Background:

  • Myxoma virus (MV) is a poxvirus used in viral vector development.
  • Efficient methods for generating recombinant MVs expressing foreign genes are crucial for research and potential therapeutic applications.

Purpose of the Study:

  • To construct an intergenic transfer vector for generating recombinant MVs.
  • To enable the expression of foreign genes, such as Escherichia coli lacZ, within the MV genome.
  • To investigate the impact of foreign DNA insertion on the transcription of adjacent viral genes.

Main Methods:

  • Construction of an intergenic transfer vector.
  • Transfection of MV-infected rabbit cells with the vector.
  • Isolation of recombinant MVs using selective growth conditions (E. coli gpt expression).

  • Analysis of gene transcription in recombinant MVs.

    • Main Results:

    • Successfully constructed a transfer vector for generating recombinant MVs.
    • Generated recombinant MVs expressing the Escherichia coli lacZ gene.
    • Demonstrated the feasibility of isolating recombinant MVs via selectable markers.
    • Investigated the transcriptional effects of inserting foreign DNA between viral genes.

    Conclusions:

    • The developed intergenic transfer vector is effective for creating recombinant MVs.
    • This system facilitates the study of foreign gene expression in MVs.
    • The findings contribute to the advancement of viral vector technology and genetic engineering.
