Oil palm phenolics (OPP) inhibit pancreatic cancer cell proliferation via suppression of NF-κB pathway

Anticancer Res. 2015 Jan;35(1):97-106.

Abstract

Background: Oil palm phenolics (OPP) or Palm Juice (PJ), a water soluble extract from the palm fruit (Elaies guineensis) has been documented to have anti-carcinogenic activities in various cancer types.

Materials and methods: To investigate OPP effects in pancreatic cancer (PaCa) cells, two PaCa cell lines (PANC-1 and BxPC-3) were treated with different OPP doses. The anti-proliferative, apoptotic and anti-invasive properties of OPP were evaluated using MTS, cytoplasmic histone-DNA fragmentation and matrigel invasive assays, respectively.

Results: OPP suppressed PaCa proliferation in a dose-dependent manner. Its anti-invasive effects were validated by decreased expressions of MMP-9 and VEGF. Cell-cycle analysis demonstrated that cells were arrested in the S phase. OPP-induced apoptosis was associated with decrease in survivin and Bcl-XL expressions and increased expression of cleaved caspase-3, caspase-9 and PARP.

Conclusion: Overall, our results demonstrate the anti-tumor effects of OPP on PaCa cells, providing initial evidence towards its potential therapeutic use.
