RCOR1 and breast cancer: Mechanism notwithstanding, repression of LINC00111 by TBX2-CoREST appears to be important for breast cancer proliferation and survival; analysis of the METABRIC dataset also indicates that breast cancer patients with LINC00111-over-expressing tumours have markedly better overall survival at months 120–240 of the study, compared to tumours in which LINC00111 is downregulated (Supplementary Figure S11).
