Associate Professor Amanda Sainsbury - Salis expressed surprise at the impact of the Y6 gene deletion on mice, commenting «I find it amazing that one gene, which is expressed in the small part of the brain that controls the body clock, has such a profound impact on how much fat is stored on the body, and how much lean tissue is maintained.»
He and a colleague took samples of both visceral and subcutaneous fat from the mice and, using gene chips, identified the genes in the fat cells as well as in precursor fat cells.
