PCOLCE and breast cancer: Four lncRNAs (AC117383.1, AC144450.1, RP11-15H20.6, and ATXN1-AS1) highly expressed in MCF-7/TamR cells were negatively related with the survival probability of breast cancer patients and other four lncRNAs (ELOVL2-AS1, PCOLCE-AS1, ITGA9-AS1, and FLNB-AS1) lowly expressed in MCF-7/TamR cells were positively related (Figures 6(a)–6(h)).
