Fig. 1. Statistical chart of significantly differentially expressed genes. Statistical chart of significantly differentially expressed genes. A represents the control group, while B represents the experimental group. RPKM indicates the gene expression in samples. FDR (false discovery rate) is a method to determine the threshold of P-values in multiple tests: assume that we have picked R differentially expressed genes, in which S genes really show differential expression and the other V genes are false positive. We use ‘FDR ≤0.001 and the absolute value of log2Ratio ≥1’ as the threshold to determine the significance of differences in gene expression. Red represents the upregulated genes in the figure; green represents downregulated genes; blue represents genes without significant differences. J. H. Tian et al. Biology Open 2016;5:764-769 © 2016.
