This could improve an older woman's chances of having a healthy baby, the team wrote. Suppressing MAPK during IVF may also help older eggs complete their development. In a press release, the scientists said t his may allow girls to maintain the high quality of young eggs until they're ready to use them. The researchers hope to one day 'gently' increase the equivalent of ogr-2 in girls via additives. 'Instantly, these "edited" worms became less fertile and their eggs more closely resembled those of an older worm.'
'We tested the gene’s role by removing it from the worm’s gene sequence,' study author Dr Yonatan Tzur said. To uncover the mechanisms behind egg ageing, the researchers looked at the roundworm species Caenorhabditis elegans.Īs well as containing the same number of genes as humans, the eggs of female worms also mature in around a day, making them easy to study.Īfter identifying ogr-2 and MAPK, the scientists removed the gene via the gene-editing tool CRISPR. This is despite more and more women choosing to delay motherhood in favour of pursuing their careers. Over time, these eggs age and lose their quality.Īgeing eggs is one of the main causes of birth defects, miscarriages and infertility, the researchers wrote in the journal Genetics. The components of CRISPR-Cas9 – the DNA sequence and the enzymes needed to implant it – are often sent into the body on the back of a harmless virus so scientists can control where they go.Ĭas9 enzymes can then cut strands of DNA, effectively turning off a gene, or remove sections of DNA to be replaced with the CRISPRs, which are new sections sent in to change the gene and have an effect they have been pre-programmed to produce.īut the process is controversial because it could be used to change babies in the womb – initially to treat diseases – but could lead to a rise in 'designer babies' as doctors offer ways to change embryos' DNA.Ī girl's eggs begin to mature after her first period, which usually occurs between 10 and 15 years old. In humans, genes act as blueprints for many processes and characteristics in the body – they dictate everything from the colour of your eyes and hair to whether or not you have cancer.
Technically called CRISPR-Cas9, the process involves sending new strands of DNA and enzymes into organisms to edit their genes. The CRISPR gene editing technique is being used an increasing amount in health research because it can change the building blocks of the body.Īt a basic level, CRISPR works as a DNA cutting-and-pasting operation.
