XIST and ovarian cancer: In addition, we found that X-linked DEGs associated with XIST loss were correlated with the density of transposable elements, LINEs but not SINES, in human ESCs; however, in human ovarian cancer and mammary cells, X-linked DEGs showed a higher correlation with SINEs than LINEs (Figure 5A; Supplementary Figure S2; Supplementary Table S4).
