Fig. 2From: Systematic analysis of lncRNA–miRNA–mRNA competing endogenous RNA network identifies four-lncRNA signature as a prognostic biomarker for breast cancerLncRNA-miRNA-mRNA competing endogenous RNA (ceRNA) network of under-expressed (a) and over-expressed (b) lncRNAs–mRNAs. In network a blue circles = down-regulated mRNAs, green rectangle = down-regulated lncRNAs, red diamonds = up-regulated miRNAs. In network b red circles = up-regulated mRNAs, pink rectangle = up-regulated lncRNAs, and blue diamonds = down-regulated miRNAsBack to article page
