Abstract

Nuphar lutea L. SM., leaf and rhizome extracts (NUP), contain nupharidines as active components. Nupharidines belong to the sesquiterpene lactones class of a naturally occurring plant terpenoids. This family of compounds has gained considerable interest for treating infection, inflammation and cancer.

NF-κB is a central, downstream regulator of inflammation, cell proliferation and apoptosis. In our previous work we demonstrated strong inhibition of NF-κB activity and induction of apoptosis by NUP. In addition, NUP exhibited anti-inflammatory properties and partial protection from LPS-induced septic shock by modulating ERK pathway and cytokine secretion in macrophages.

In the present study, we examined the effect of NUP in a B16 melanoma experimental murine lung metastasis model and its ability to affect the ERK and NF-κB pathways in variety of cell lines.

We showed that NUP and cisplatin combined treatment was synergistic and reduced the lung metastatic load. In addition NUP treatment inhibited TNFα-induced IκBα degradation and NF- κB nuclear translocation. We also observed that NUP induced ERK activation. Furthermore, ERK inhibition prevented NF-κB inactivation by NUP.

Overall, our work implies that co-administration of NF-κB inhibitors such as NUP, with standard anti-cancer drugs, may act as “sensitizers” for more effective chemotherapy.

Keywords: Nuphar lutea plant extract, nupharidines, melanoma, ERK, NF-κB.
