Glaucarubinone Combined with Gemcitabine Improves Pancreatic Cancer Survival in an Immunocompetent Orthotopic Murine Model.


ABSTRACT:

Background

Pancreatic cancer continues to have a poor survival rate with an urgent need for improved treatments. Glaucarubinone, a natural product first isolated from the seeds of the tree Simarouba glauca, has recently been recognized as having anti-cancer properties that may be particularly applicable to pancreatic cancer.

Methods

The effect of glaucarubinone on the growth and migration of murine pancreatic cancer cells was assessed by 3H-thymidine incorporation assay. The survival impact of glaucarubinone alone and in combination with gemcitabine chemotherapy was assessed using an immunocompetent orthotopic murine model of pancreatic cancer.

Results

Glaucarubinone inhibited the growth of the murine pancreatic cancer cell lines LM-P and PAN02. Treatment with either glaucarubinone or gemcitabine reduced proliferation in vitro and the combination was synergistic. The combination treatment improved survival two-fold compared to gemcitabine treatment alone (p = 0.046) in PAN02 cells.

Conclusions

The synergistic inhibition by glaucarubinone and gemcitabine observed in vitro and the improved survival in vivo suggest that glaucarubinone may be a useful adjunct to current chemotherapy regimens.
