To evaluate the possible significance of high nuclear levels of CtBP and LSD1 in breast cancer survival, we utilized a unique resource of patient samples in which nuclear, CtBP1, CtBP2, and LSD1 have been quantitatively determined and compared to paired gene expression data based on RNA-seq analysis (Material and methods, also see Supplementary Fig. 3). Here, KDM1A is linked to breast carcinoma.
