Bad knockdown can enhance p53/caspase-8 death signaling. (A) Identification of Bad knockdown by specific morpholino (Bad-MO) at 8 hpf via Western blot analysis. (B,C) TUNEL-positive spot staining (indicated by arrows) at 8 hpf with Bad knockdown by Bad-MO. The Bad-MO group shows more signal than the Bad-M5 (Control group). TUNEL-positive spots within the embryo were counted and are shown in (C). The DNase I treatment group was used as a positive control. (D,E) Analysis of apoptotic-related genes during development and cell-death-related genes by qRT-PCR at 8 hpf with Bad knockdown. All data were analyzed using either paired or unpaired Student’s t-tests, as appropriate. TUNEL-positive cells under the fluorescence microscope are considered apoptotic.
