Identification of differentially expressed genes (DEGs). a, box plot of data after normalization. The horizontal axis refers to the sample name and longitudinal axis refers to expression values. The black line in box was the median of each set of data, through which we could determine the extend of standardization of data. The black line in box was almost in the same line which indicates good normalization. b, venn diagram of DEGs at different time points. c, heat map of overlapping DEGs. Red indicates up-regulation and green indicates down-regulation
