Sphingosine kinase inhibitor slows castration-resistant prostate cancer cell growth

Sphingosine kinase inhibitor slows castration-resistant prostate cancer cell growth: A first-in-class sphingosine kinase 2 inhibitor slowed the growth of castration-resistant prostate cancer cells, in part by inhibiting the enzyme dihydroceramide desaturase (DEGS), but did not kill them, according to the results of preclinical in vitro and in vivo studies published in the December 2015 issue of Molecular Cancer Therapeutics by researchers at the Medical University of South Carolina and others.
