Genetic deletion of SphK1 reduced CLDN2 in HER2/neu-induced mice breast tumors. (A) Whole genome expression profile evaluated by microarray analysis assessed the expression of 39000 gene transcripts. Gene expression microarray heatmap (n = 2 per group) of dysregulated genes. (B) Twenty molecules with the most significant expression changes (10 up-regulation and 20 down-regulation) between SphK1+/+ and SphK1−/− tumors are shown. (C) CLDN2 mRNA expression in tumors from SphK1+/+ and SphK1−/− mice was confirmed by qRT-PCR analysis and analyzed by unpaired t-test. ****P ≤ 0.0001 vs. SphK1+/+. (D) Representative paraffin-tumor sections immunostained for CLDN2 in tumors from SphK1+/+ and SphK1−/− mice (P = 0.1339).
