Some of them are under investigation such as circulating tumor cells (CTCs), PTEN, androgen receptor variants, long non-coding RNAs such as HOX transcript antisense intergenic RNA [102, 103], SChLAP1 and MaLAT-1, and several miRNAs such as miRNA-141 and miRNA-301a. Here, SCHLAP1 is linked to neoplasm.
