SLC45A3 and prostate cancer: The tissues harbour the cis-SAGe SLC45A3-ELK4 (Tables S15-S17) which contributes to cell proliferation in prostate cancer [32], Two fusion variants were identified in the bulk RNA-sequenced tissue sections: SLC45A3-ELK4 exon 4-exon 2 and SLC45A3-ELK4 exon 5-exon 2 (Fig. S1, Table S18).
