Scientists have finally identified a gene linked to diabetes and cholesterol that might act as a 'master switch' that controls other genes found in fat in the human body which could help treat obesity which affects more than half a billion people worldwide, or one in ten adults. The gene is known as KLF14 and it was already known to be linked with diabetes and cholesterol, but it's role was not known until now. Scientists say KLF14 controls the levels of many other genes found primarily in fat tissue.  The gene is also linked to body mass index and obesity. If they can understand the processes of the gene, they hope to be able to improve treatments for conditions like diabetes and obesity. Click here to read the entire huffingtonpost.com article.
