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...

Homologous Recombination

50.0K
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

CRISPR and crRNAs

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

Conservative Site-specific Recombination and Phase Variation

5.9K
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...

Area of Science:

  • Bioethics
  • Genetics
  • Public Policy

Background:

  • International summits since 2015 have addressed the complex ethical landscape of human heritable genome editing.
  • Discussions have centered on safety, efficacy, moratoriums, and the necessity of broad societal consensus.

Purpose of the Study:

  • To trace the evolution of ethical discussions surrounding human heritable genome editing across three major international summits (2015, 2018, 2023).
  • To analyze the shifting perspectives on key ethical considerations, including safety, efficacy, moratoriums, and societal consensus.
  • To differentiate between the fundamental ethical question of whether human heritable genome editing is permissible and the question of whether it can be performed ethically.

Main Methods:

  • A review and analysis of publications and discussions from the 2015 Washington, DC; 2018 Hong Kong; and 2023 London international summits on human heritable genome editing.
  • Tracing the thematic development of ethical considerations over time.

Main Results:

  • The ethical discourse has progressed, with increasing emphasis on the nuances of safety, efficacy, and the interpretation of moratoriums.
  • The concept of broad societal consensus has remained a critical, albeit evolving, element in the ethical debate.
  • A distinction has emerged between the inherent ethical permissibility of human heritable genome editing and the ethical considerations for its practical application.

Conclusions:

  • The ethical considerations for human heritable genome editing are multifaceted and have evolved significantly over recent years.
  • Future ethical frameworks must address both the fundamental permissibility and the practical, ethical implementation of this technology.
  • Continued dialogue and broad societal engagement are crucial for navigating the ethical challenges of human heritable genome editing.
