Immunity related genes in dipterans share common enrichment of AT-rich motifs in their 5' regulatory regions that are potentially involved in nucleosome formation

Table 1 Number of 5' upstream sequences analyzed according expression pattern and functional class.

Organism	Immunity up-regulated	Down-regulated	Non modified	Random genes	Artificial
*Anopheles gambiae*	18	16	19	20	20
*Drosophila melanogaster*	36	29	32	30	30

Groups of A. gambiae and D. melanogaster genes selected for in silico analysis for searching potential DNA regulatory motifs. 2500 nucleotides were analyzed.
