Potential biological function of aberrantly expressed lncRNAs in breast cancer. a & b Gene ontology enrichment analysis (left) and KEGG analysis (right) for 30 upregulated lncRNAs from cohort I and cohort II. c & d Gene ontology enrichment analysis (left) and KEGG analysis (right) for 25 downregulated lncRNAs from cohort I and cohort II. e & f Gene ontology enrichment analysis for 1712 upregulated coding genes (left) and 1269 downregulated coding genes (right) from cohort I and cohort II. g & h KEGG analysis for 1712 upregulated coding genes (left) and 1269 downregulated coding genes (right) from cohort I and cohort II. P-values <0.05 were defined as statistically significant. The vertical axis represents the biological procession or pathway category, and the horizontal axis represents the –log10 (P value) of these significant biological processions or pathways
