Phenotypes of adcy9 zebrafish morphants. (a-f) Gross morphology at 3-dpf. Compared with control MO, knock down adcy9 present pericardial oedema (b, d, f, red arrow) (Heart beat is visible in the control fish, but is abnormal in adcy9-e3i3-MO injected fish (Supplementary Movie 1, Supplementary Movie 2). The bar graph in Panel G shows the percentage of embryos with development defects. h A time-course plot of percent survival in control vs. adcy9 morphants for 5 days

Effects of adcy9 knock down on macrophage migration. a-f Representative bright field and fluorescent images of TG (zlyz: EGFP) larvae at 6 days postfertilization (dpf). Control MO injected fish show the normal distribution of labeled cells (b and c). Compared with control fish, embryos injected with adcy9-e3i3-MO present potent macrophage migration in heart (e and f, red circle area). g-k Quantification of the macrophage number at heart shows a 13.3-fold increased in adcy9 morphants. Columns, mean; bars, SEM (n = 10; Student’s t test; ***P < 0.0001;). dpf, days post fertilization. l Endogenous efnb2a, COX2, mmp9, ptp-rb and pik3r2 in control and adcy9 morphants assessed by qRT-PCR (n = 6–10 individual embryos). ns, not significant

Morpholino knock down of adcy9 induces potent apoptosis in heart. Control-MO injected embryos and embryos injected with adcy9-e3i3-MO were stained with acridine orange (AO) at 3-dpf. Heart apoptotic cells are visible as bright green spots or red spots (f-h), and less bright homogenous green staining is unspecific background staining. a-d Control-MO injected zebrafish exhibited few or no apoptotic cells in heart. In contrast, significantly increased staining was observed throughout the heart in zebrafish injected with 4 ng adcy9-e3i3-MO (F-H). The red boxed regions are shown at higher magnification in the right panels. i Quantification of apoptosis particle number at heart shows a 66.1-fold increased in adcy9 morphants. Error bars, s.e.m.; ***P < 0.0001(n = 10; Student’s t test;); a-h: lateral view, anterior, left. Dpf, days post fertilization. j Endogenous tnfsf10l3, hdr, tnfrsfa, caspase-8, tp53, pmaip1, bbc3, badb, baxa, baxb, caspase-3a and caspase-a in control and adcy9 morphants assessed by qRT-PCR (n = 6–10 individual embryos). ns, not significant
