The absence of rag1 and excessive apoptosis in rpc9-/- embryos can be rescued by knockdown of P53. (A) qRT-PCR result revealed that p53 was significantly increased in rpc9-/- embryos at 3 and 4 dpf. β-actin was used as internal control (mean±SD, *P < 0.05, **P < 0.01) . (B) WISH result demonstrated the decrease of rag1 in the thymus of rpc9-/- embryos at 5 dpf could be rescued by p53-deficiency. Arrowheads mark the thymus. Arrowheads mark the thymus.

(C) TUNEL assay demonstrated apoptosis in the CHT of rpc9+/+ and rpc9-/- embryos that injection with control or p53 MO at 4 dpf. (D) Statistical data of (C) revealed that apoptosis signals in rpc9-/- embryos could be significantly repressed by injection of p53 MO at 4 dpf (mean±SEM, ***P < 0.001). (E) pH3 assay demonstrated proliferation in the CHT of rpc9+/+ and rpc9-/- embryos that injection with control or p53 MO at 4 dpf. (E) Statistical data of (F) revealed that proliferation signals were not significantly altered between rpc9-/- embryos that injected with control or p53 MO at 4 dpf (mean±SEM, ns, no significant). (G) WISH showed no obvious alteration of expression of arterial markers dlc and dll4 in rpc9-/- embryos.
