Genetic and pharmacological inhibition of AAR, but not UPR, suppresses the tars-deficiency-induced angiogenesis.

a, b Quantification and statistical analysis of the ectopic branch points per ISV of the tars^?/^? and sibling embryos that were treated with gcn2 MO or perk MO. c Knockout of gcn2, but not perk, suppressed the tars-deficiency-induced angiogenesis. The embryos were produced by self-cross of gcn2^?/^?tars^+/^? or perk^?/^?tars^+/? lines, and the tars^?/^? ones were compared with their siblings in the same litter. d Pharmacological inhibition of Gcn2 by GCN2-IN-1 and GCN2iB significantly suppressed the angiogenic phenotypes of the tars^?/^? embryos. e Inhibition of Perk by Perk-specific inhibitor GSK2656157 showed no significant rescue effect on the angiogenetic phenotypes. f Attenuation of UPR by 4-phenylbutyrate (4-PBA) could not rescue the angiogenetic phenotypes. In panels d?f, the solvents DMSO and H₂O were applied as negative controls, respectively. In the statistical analyses, data are presented as means � SD; two-tailed t-test; ***P < 0.001; n.s., not significant.
