Deletion ofMTAPHighly Sensitizes Osteosarcoma Cells to Methionine Restriction With Recombinant Methioninase

Abstract excerpt

BACKGROUND/AIM: Methionine addiction is a fundamental and general hallmark of cancer cells, which require exogenous methionine, despite large amounts of methionine synthesized endogenously. 5-Methylthioadenosine phosphorylase (MTAP) plays a principal role as an enzyme in the methionine-salvage pathway, which produces methionine and adenine from methylthioadenosine and is deleted in 27.5% to 37.5% of osteosarcoma...
