qRT-PCR analysis also showed that the angiogenesis-related genes, Angpt1 (Ezaki et al., 2024), Id1 (Guo et al., 2023), and Lyve1 (Lu et al., 2023), were significantly upregulated at 10 weeks post-infection, and Pecam1 (Zhang et al., 2024) was significantly upregulated at 10–12 weeks post-infection. The gene discussed is PECAM1; the disease is infection.
