Differential expression of lncRNAs after T. gondii infection. a The hierarchical clustering of significantly differentially expressed lncRNAs (fold change ≥ 5, P < 0.05) between the uninfected HFF cells (uninfected), the inactived T. gondii-infected HFF cells (inactivated) and the T. gondii-infected HFF cells (T. gondii). In the heat map, red indicates the high relative expression, and green indicates the low relative expression. b Venn diagrams indicate the number of total and overlapping lncRNAs with the significant differential expression in the T. gondii group, compared with the uninfected and inactivated groups, respectively. c and d Real time quantitative PCR (RT-qPCR) validation of the upregulated and downregulated lncRNAs (fold change ≥ 5, P < 0.05) from the microarray data
