Figure 5: Functional categories identified by bioinformatic analysis of differentially expressed genes in the rabbit basilar artery after SAH. Each functional category was identified by IPA and divided into three groups (day 3, day 5, and day 7) by the peak of its negative log of the p-value. Then, functional categories were arranged in descending order according to the negative log of the p-value. The negative log of the p-value in each function on days 3, 5, and 7 are presented in bar charts and are colored dark blue, blue, and light blue, respectively. The orange horizontal line indicates the threshold of significance, preset at a p-value of 0.05.
