PVT1 and breast cancer: In this study, we investigated the expression profiles of a panel of plasma lncRNAs—BCO40584, AK58003, HOTAIR, CCAT1, CCAT2, MALAT1, PVT1, promoter of CDKN1A antisense DNA damage activated RNA (PANDAR), urothelial cancer associated 1 (UCA1), and sprouty RTK signaling antagonist 4-intronic transcript 1 (SPRY4-IT1) and the genes SNCG and BDNF in metastatic and non-metastatic BC cases compared with their expressions in benign breast diseases and healthy controls to identify the lncRNAs specifically associated with BC.
