In addition, we report several novel effects of deactivators and infection on the expression of known genes: (1) IL-4 caused pronounced upregulation of ABCG2, coding for an ATP-binding cassette transporter highly expressed in the placenta, which mediates multidrug resistance of cancer cells, but is otherwise of unknown function; (2) both DEX and IL-4 downregulated osteopontin, an important factor of host resistance against intracellular infections; (3) inhibition of the CC-chemokine I-309 mRNA expression by all three deactivators in the presence of Listeria infection, and (4) upregulation by Listeria infection of the interferon-stimulated gene ISG20 of unknown function, whose product localizes with nuclear dots/PML bodies.
