Gene-editing in IVF made a big breakthrough this month and the CRISPR technology is now a reality. Here we catch up with Paula Amato and the team from Oregon Heath Sciences behind latest breakthrough.

2025年1月22日 · CRISPR Gene Editing for Embryo Health. Still in its infancy, CRISPR technology is being explored to prevent genetic disorders in embryos. What’s new: Researchers are focusing on precision editing techniques to eliminate inherited diseases. Ethical considerations: Strict guidelines are being enforced to ensure ethical use. 3.

CRISPR/Cas9 makes use of a naturally occurring defence mechanism that bacteria use to avoid harmful infections caused by pathogenic organisms (e.g. viruses). The RNA tool (CRISPR) functions as a guide for the Cas proteins to target specific parts of the genome, which are subsequently cut by the Cas proteins.

2017年8月2日 · Molecular scissors known as CRISPR/Cas9 corrected a gene defect that can lead to heart failure. The gene editor fixed the mutation in about 72 percent of tested embryos, researchers report August...

2023年8月31日 · This was evidenced by the near universal dismay, disapproval, and disbelief that met the 2018 announcement of twin girls born in China after the treatment of in vitro fertilization (IVF) embryos using the genome editing technology known as CRISPR.

2019年6月19日 · By conceiving through in vitro fertilization (IVF) and screening the embryos, Carroll and his wife could all but eliminate the chance of passing on the mutation. They decided to give it a shot,...

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a “gene editing” technique. These repeats can be cut by an enzyme called Cas9 when the appropriate nucleotide match pairs with it.

Despite the concern of the scientific community and societies on prohibition of gene editing in human embryos, a Chinese scientist, He Jiankui, used CRISPR/Cas9 system through in vitro fertilization (IVF) process to delete the gene copies responsible for the HIV receptor in …

HIV transmission can generally be prevented by sperm washing before in vitro fertilization. This ties in with the second theme: that of risks to future children and parental freedoms. Today, recourse to in vitro fertilization in the situation of infertility or serious genetic conditions is a recognized medical treatment.

A group led by Dr Shoukhrat Mitalipov of the Oregon Health and Science University in Portland published a study in Nature last year describing how they used CRISPR/Cas9 genome editing to repair a genetic variant in human embryos responsible for a heart condition.
