Growth hormone contributes to polycystic kidney disease
The Missing Link:
The Fragiadaki team has discovered that STAT5, a protein expressed by our kidneys, is activated and responsible for the abnormal growth of cysts in the kidney. Specifically, they have found that mice with polycystic kidney disease not only do they have elevated STAT5 activity but also have unusually high levels of a hormone, known as growth hormone, which may contribute to the progression of disease. Growth hormone is a natural hormone produced by the pituitary (master) gland of the brain.
Identifying that abnormal STAT5 activity contributes to polycystic kidney disease in mice was an exciting discovery. Our next goal is to understand how this pathway is activated in order to provide new targets for therapy.
