IGF1 plays key role in T-cell acute lymphoblastic leukemia

There are numerous specialized growth factors that are responsible for cells of different tissues of our body to divide and differentiate when needed. These hormone-like factors bind to matching receptors on the surface of their target cells and thus give order for the cell to divide. However, a single genetic alteration can be sufficient for the whole system to get out of control.
