Abstract:Polyamines are essential growth factors for normal and malignant cells. Cells obtain polyamines via biosynthesis or transport from the extracellular environment and polyamine depletion therapy is an attractive option to inhibit the growth of cancer cells. Previous reports have indicated that depletion therapy (e.g. androgen depletion in prostate cancer) can lead to epigenetic changes resulting in resistance to the therapy and aggressive metastatic cancer. We were interested to know if polyamine depletion drive… Show more
