      The MDM2-p53 pathway plays a prominent role in well-differentiated liposarcoma (LPS) pathogenesis. Here, we explore the importance of MDM2 amplification and p53 mutation in LPS independently, to determine whether HDACi are ...

    • Inhibition of KIT-Glycosylation by 2-Deoxyglucose Abrogates KIT-Signaling and Combination with ABT-263 Synergistically Induces Apoptosis in Gastrointestinal Stromal Tumor
