question:
 In an attempt to clarify mechanisms by which FA - C cells overexpress IFNgamma - inducible genes in the face of defective STAT1 phosphorylation , it was reasoned that decreased levels of activated STAT1 might result in reduced expression of a hematopoietic IFNgamma - responsive protein that normally modulates expression of other IFNgamma - responsive genes .
answer:

activated STAT1
