SCIENTISTS HAVE DISCOVERED THE GENE THAT CAUSES GREY HAIR सफ़ेद बाल
If you’ve been looking for a way to fight the grey hair and bath in the fountain of youth then a solution may be on its way.
Genetics aside, scientists have tracked down the specific gene which leaves people with grey hair as they age. A report via CBS News and Nature Communications discovered that the IRF4 gene which was known in the past to cause light hair in people of European descent is also the very gene that is linked to causing grey hair.
The salt and pepper research involved analysing the DNA of 6,000 individuals across Brazil, Colombia, Chile, Mexico and Peru to determine the genes which defined hair colour, density and texture. It was this diverse gene pool that helped the scientist isolate the IRF4 gene.
The study’s author, Kaustubh Adhikari, from the University College London said that, “we already know several genes involved in balding and hair colour, but this is the first time a gene for greying has been identified in humans, as well as other genes influencing hair shape and density.”
The gene’s purpose in the human body is to regulate and produce melanin, the property which gives human’s their hair, eye and skin colour. When the production of melanin begins to slow, grey hairs will occur. The exact amount of melanin the body produces is dependent on genetics.
Adhikari explained that as hair greys, something happens that causes this gene to produce even lower levels of melanin.
“Now we can ask more specific functional questions,” he added.
Scientists are optimistic that this latest study and identification of the grey gene will help in slowing down the process whilst understanding ageing. Given that humans have already modified animal genes to their advantage, this is definitely not far from reality. These exciting new findings will also aid in the fields of forensic science and anthropology.
