1% NP-40) containing proteinase (Roche) and phosphatase (Roche)
inhibitor cocktails. Samples were resolved using 4–12% SDS-PAGE
gels (Life Technologies) and transferred to PVDF membranes (Millipore).
Membranes were probed overnight on a 4°C shaker with primary antibodies
(1:1,000 dilution unless indicated) recognizing the following proteins: p-AKT
(Ser473) (9271, Cell Signaling), AKT (4691, Cell Signaling), p-S6 (Ser240/244)
(5364, Cell Signaling, 1:20,000), p-4E-BP1 (Thr37/46) (2855, Cell Signaling),
p-AURKA (Thr288) (3079, Cell Signaling), AURKA (4718, Cell Signaling), Cleaved
PARP (Asp214) (9541, Cell Signaling), BCL2 (2870, Cell Signaling), BAX (2772,
Cell Signaling), MYC (ab32072, Abcam), and β-actin (3700, Cell
Signaling).
