Fig. 4 Apoptosis is synergistically increased when Appa and Prp1 levels are reduced. A–D.
Zebrafish injected with a control morpholino (MO), low dose (sub-effective) prp1 MO, low dose (sub-effective) appa MO, or a combination of sub-effective appa and prp1 MOs (A–D, respectively) showed increased abundance of activated-caspase 3-positive cells (A′–D′, respectively). Higher doses of MOs used in this same assay showed individual MOs can also produce this effect (Fig. S7). E. Activated caspase 3-positive cells were slightly increased when low doses of prp1 or appa MOs were injected alone and synergistically increased when they were combined in one injection solution. N = 5. ** = P<0.01, * = P<0.05.
