A great leap in the treatment of hereditary pathologies of vision: gene therapy

Of all the advances that scientific and technological development has brought in the field of hereditary pathologies that affect vision, the most relevant and transcendent for the patient is the possibility of applying treatments for diseases that, until now, were considered incurable. . 30 years ago a new type of therapy was successfully started: gene […]

TwinPE: An improved genome-editing tool that allows inserting entire genes for gene therapy

Researchers at the Broad Institute of Harvard University have just reported in the scientific journal Nature Biotechnology an improved version of prime editing, the highly accurate genome editing method developed in 2019 by the same team. This new version, called twin prime editing (twinPE), allows insertion of DNA fragments of the size of a gene into specific sites of […]

Novel high-precision gene therapy to correct an eye disease in mice

Researchers from the Seoul National University (Korea) have applied for the first an improved genome-editing methodology, named prime editing to correct the genetic defects of two animal models of human disease: a liver disease (hereditary tyrosinemia) and an eye disease (Leber congenital amaurosis). This high-precision genome-editing tool, developed only two years ago by the team […]

Researchers devise a novel, high-precision, gene-editing tool to fix genetic diseases

In recent years, a powerful gene-editing technology called CRISPR-Cas9 has revolutionized biology turning the process of genome modification into an easy and inexpensive process. This revolutionary technique makes use of molecular tools that allow precise identification of DNA fragments –for example a gene– and either introduce modifications, delete a genomic fragment, or even insert a […]
