Area of Science:

  • Molecular Biology
  • Virology
  • Gene Therapy

Context:

  • Lentiviral vectors, including pseudotyped HIV, are crucial tools for gene delivery.
  • Efficient gene transfer into target cells is essential for therapeutic efficacy.
  • Developing high-titer, efficient viral vectors is a key goal in gene therapy research.

Purpose:

  • To evaluate the efficiency of pseudotyped HIV as a gene transfer vector.
  • To assess the gene delivery and therapeutic potential of pseudotyped HIV carrying the HSV-tk gene.
  • To investigate the cytotoxicity of the HSV-tk/GCV system in cancer and normal cells.

Summary:

  • Pseudotyped HIV gene transfer vectors were constructed and validated using GFP and HSV-tk genes.
  • Efficient transduction and transcription of the HSV-tk gene were confirmed in SKOV3 (ovarian cancer) and GF (fibroblast) cells.
