Article Title: Synergistic Effects of Targeted PI3K Signaling Inhibition and Chemotherapy in Liposarcoma

doi: 10.1371/journal.pone.0093996

Figure Lengend Snippet: SW872 and SW982 cells were treated with different concentrations of PI-103 for 24 hours. The effects of PI-103 on PI3K/mTOR pathway protein expression levels were determined by West blot analysis. Note the significant decrease in pAKT and p4EBP1 expression in both of liposarcoma cell lines post PI-103 treatment.

Article Snippet: The human AKT, phosphorylated AKT (pAKT) (threonine [Thr]308), PI3K p110α, phosphorylated 4E binding protein 1 (p4EBP1) (Thr37/46), BcL-XL, Cytochrome c, caspase 3, mTOR, phosphorylated mTOR (pmTOR) antibodies were purchased from Cell Signaling Technologies (Dedham, MA).
