The SLC45A3-ELK4 fusion, but not wild-type, ELK4 plays important roles in regulating cell growth in both androgen-dependent and -independent prostate cancer cells.     ///    "With the absence of corresponding DNA rearrangement, chimeric fusion SLC45A3-ELK4 transcript in prostate cancer cells is generated by cis-splicing of adjacent genes/gene read-through instead of trans-splicing. "    ///    "Here, we show that a chimeric SLC45A3-ELK4 RNA is generated in the absence of chromosomal rearrangement. "    ///    "SLC45A3-ELK4 controls prostate cancer cell proliferation, and the chimera level correlates with prostate cancer disease progression.. "
