Meet your genetic master of fat

One gene linked to type 2 diabetes and cholesterol may act as a "master regulator" gene that controls how fat works in the body, according to a study published in Nature Genetics.

Scientists had known that the KLF14 gene is linked to type 2 diabetes and cholesterol but didn’t know what role it played in controlling other genes.  KLF14 gene is inherited from the mother.

The researchers from King’s College London and University of Oxford say that the study indicates that one master gene can cause a “cascade of other metabolic effects in other genes” linked to obesity, HDL cholesterol, insulin and glucose levels.  They believe KLF14, thereby “acts as a master switch.” They examined 20,000 genes in 800 female twins to determine that association.

The findings mean that the  KLF14 gene could become the possible target for treatment efforts to fight against diseases related to metabolism and obesity.

In a press release, a co-author of the study, Mark McCarthy from the University of Oxford, said: "KLF14 seems to act as a master switch controlling processes that connect changes in the behavior of subcutaneous fat to disturbances in muscle and liver that contribute to diabetes and other conditions. We are working hard right now to understand these processes and how we can use this information to improve treatment of these conditions."

    I am from united states. I am 36 years old, work as staff in Walmart, i and my Husband has been married for 5 years but recently he started cheating on me which i caught him, this led to our breakup, he left the house to be with the other lady, i tried as much as possible to bring him back because i still loved him but he never came back, after a while i found he told me he had Herpes and asked me to check myself too which i did and i found that i have too, i was frustrated, i start taking various treatment, i read a lot too about this virus then i came across this https://robinbuckler. com which said he can treat herpes with herbal medicine, i contacted him and purchased and he told all to be done and told me how to use his herbs which i did for 2 weeks and i was amazed by the outcome, i was cured. he also did a love spell for me to bring my lover back which took place just in 24 hours, my lover came back and since then he has been so loving and caring, no more lies, no cheating, he also got cured from herpes too, this is awesome, unbelievable.......this is his email address___________________ robinson.buckler @t [yahoo] com.....

    Thank you for the sensible critique. Me & my neighbor were just preparing to do a little research about this. We got a grab a book from our area library but I think I learned more clear from this post. I'm very glad to see such great information being shared freely out there.
