Research of lncRNAs in PCa has revealed its role in cancer development and progression, epigenetic regulation (eg, CTBP1‐AS, HOTTIP, NEAT1)210, 211, 212, transcriptional regulation (NEAT1, SChLAP1),210, 213 as decoys and also as a sponge for microRNA (eg, PTENP1, KRAS1P, and PCAT1).214, 215, 216, 217, 218. The gene discussed is PTENP1; the disease is cancer.
