While JNK-mediated control of ftz-f1 transcription has not been reported previously, upregulation of ets21c in our tumor model is consistent with JNK requirement for infection-induced expression of ets21c mRNA in Drosophila S2 cells and in vivo (Boutros et al., 2002; Radyuk et al., 2010; Chambers et al., 2012). The gene discussed is MAPK8; the disease is infection.
