Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...
Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
DNA-only Transposons02:57

DNA-only Transposons

DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...
In-vitro Mutagenesis01:16

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
CRISPR01:59

CRISPR

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...

Area of Science:

  • Molecular Biology
  • Genetics
  • Biotechnology

Background:

  • Viral and transposon vectors are used in gene therapy and functional genomics.
  • Gene therapy aims to avoid altering endogenous gene expression, while functional genomics seeks to modify it.
  • Vector integration preferences influence the outcomes of these applications.

Purpose of the Study:

  • To compare DNA vectors with viral vectors for gene delivery.
  • To review methods for overcoming DNA vector delivery barriers.
  • To analyze vector integration tendencies concerning oncogenic risks and gene expression modification.

Main Methods:

  • Discussion of relative strengths of DNA versus viral vectors.
  • Review of methods to enhance DNA vector delivery.
  • Analysis of retroviral and transposon vector integration preferences.

Main Results:

  • Vector integration preferences vary significantly between different vector types.
  • Understanding these preferences is key to predicting and controlling gene expression changes.
  • Specific vector classes show distinct targeting patterns for DNA sequences, genes, and regulatory elements.

Conclusions:

  • Knowledge of vector integration variables enables informed vector selection for specific research or therapeutic goals.
  • Elucidating integration factors aids in assessing gene therapy risks (oncogene activation, tumor suppressor inactivation).
  • This understanding facilitates the design of improved, targeted vectors for transgenesis in both gene therapy and functional genomics.
