Fig. 2From: Sphingosine kinase 1 expression enhances colon tumor growthSphK1 overexpression in intestinal epithelial cells significantly increase tumor development induced by AOM. a Dox treatment induces SphK1 expression in intestinal epithelial cells. b SphK1 overexpression significantly increases tumor multiplicity induced by AOM (P < 0.05). The data is presented as mean ± SEM; *P < 0.05 vs. GFP controlBack to article page
