INS and acute lymphoblastic leukemia: Though falling short of our shared > 2 log2 fold change threshold, insulin-like peptide gene, daf-28, was the single most differentially regulated ins gene, exhibiting a polarised expression pattern that correlates inversely with both enhanced chemotaxis toward G. mellonella (S. carpocapsae Breton), and reduced nictation behaviour (S. carpocapsae UK1) (down-regulated 1.1 and 2.8 log2 fold, P < 0.0001**** in Breton relative to ALL and UK1, respectively; up-regulated 1.7 and 2.8 log2 fold, P < 0.0001**** in UK1 relative to ALL and Breton, respectively) (Fig. 2c-d; Additional file 2).
