AKT1 and myxoid liposarcoma: Moreover, myxoid liposarcomas were associated with FUS:DDIT3‐driven induction of insulin‐like growth factor 2 (IGF2) expression and activation of insulin‐like growth factor 1 receptor (IGF‐IR)/phosphoinositide 3‐kinase (PI3K)/AKT serine/threonine kinase 1 (AKT) signaling (Trautmann et al, 2017), overexpression of fibroblast growth factor receptor 2 (FGFR2) (Künstlinger et al, 2015), and activation of casein 2 kinase/atypical nuclear‐factor kappaB signaling (Willems et al, 2010).
