Abstract 3215: Role of pterostilbene on proliferation, invasion, and migration in ovarian and uterine cancer cells

Abstract

Abstract PURPOSE: To determine the functional effects of the resveratrol analog, pterostilbene (PTE), and its potential adjuvant role with cisplatin, in ovarian and uterine cancer cells. EXPERIMENTAL DESIGN: The human ovarian cancer cell lines (OVCAR8, SKOV3) and uterine cancer cell lines (HEC1A, ECC1) were obtained from ATCC, and grown according to standard protocols using recommended media. Standard proliferation (MTT) and migration assays were performed in routine fashion, with or without PTE +/- cisplatin treatment. For the in-vitro Cell Proliferation Assay, different concentrations of cisplatin (3 - 50 μM), pterostilbene (PTE) (30 - 500 μM), or both in combination were added for 72 hours. Cell migration was assayed using 24-mm diameter chambers with 8-μm pore filters, with or without treatment of PTE and cisplatin, and migrated cells were counted using Image-pro program. A synergistic analysis from the MTT assay results was calculated via the CompuSyn for Windows computer program based on the combination index (CI) theorem of Chou-Talalay, to determine the presence of synergy between cisplatin and PTE. RESULTS: PTE reduces proliferation in OVCAR8, SKOV3, HEC1A, and ECC1 cells, and its anti-proliferative effect approaches that of cisplatin. Addition of PTE to cisplatin potentiates the anti-proliferative effects of cisplatin in HEC1A, ECC1, SKOV3, and OVCAR8 cells. The combined effect of PTE and cisplatin is synergistic in OVCAR8 cells based on synergy calculations (CI<1). PTE reduces cell migration in HEC1A and OVCAR8 cells, and its addition to cisplatin treatment improves the anti-migratory effect. CONCLUSIONS: Pterostilbene, a resveratrol analog with improved bioavailability, reduces proliferation and migration in ovarian and uterine cancer cells, and potentiates the anti-proliferative and anti-migratory effects of cisplatin, thus presenting as an attractive non-toxic alternative for potential adjuvant chemotherapy in ovarian and uterine cancer.
