AKT is required for stabilization of zEtv2 and zScl. (A,B) Protein levels of zEtv2 and zScl were decreased in PAA clusters of cxcr4a?/? mutants. (C,D) Expression analysis of zEtv2 and zScl in wild type (WT) and cxcr4a?/? mutants on the Tg(nkx2.5:ZsYellow) background treated with 10 ?M MK-2206 or 0.5 ?M SC79 from 18 to 38 hpf. (E-H) HEK293T cells were transfected with indicated plasmids. (E,G) 24 h later, cells were treated with CHX (20 ?g/ml) for the indicated times and harvested for immunoblotting. (F,H) Protein levels were quantified and normalized to tubulin (meanąs.d., three independent biological replicates). Scale bars: 50 ?m.
