New gene for hairloss

...They investigated the function of the protein that cells normally make with instructions from the hairless gene.Results suggest that it helps regulate genes that are activated by thyroid hormone. The hairless protein acts to shut those genes down when thyroid hormone is absent, researchers concluded.George...
