Cell-cycle-progression defects in the C1q-like morphant embryos. (A) The up-regulated expression changes of p21WAF1/CIP-1 (p21), p53, mdm2, bax and caspase 3 revealed by Q-RT-PCR in the C1q-like morphants. The ratio of these genes to β-actin in control embryos was set to 1, and all C1q-like MO treated embryos were normalized relative to this value. The date represent mean ± SD of three separate experiments. (B) The labeled G2/M phase cells of head regions in control (a), the C1q-like morphant (b) and co-knockdowns of C1q-like and p53 (c) embryos at 24 hpf recognized with the antibody against phosphorylated histone H3 (pH3). (C) A typical FACS analysis data of propidium-iodide-labeled cells in control (a), the C1q-like morphant (b) and co-knockdowns of C1q-like and p53 (c) embryos at 24 hpf. (D) The statistical data of three independent experiments of (C). *p < 0.05 and **p < 0.01.
