The idea that both STAT2 and IRF - 9 were basic components necessary for RIG - G expression was also supported by the fact that ATRA could not only induce the total amounts of STAT2 and IRF - 9 proteins but also increase
the tyrosine phosphorylation level of STAT2 in NB4 cells (Fig. 1A).

At a molecular
level, loss of insulin signaling in astrocytes impaired
tyrosine phosphorylation of Munc18c.
The results revealed that the supernatant of 72 - hour ATRA - treated NB4 cells was sufficient to induce the
tyrosine phosphorylation of STAT2 and the endogenous RIG - G
level in U3A cells, in comparison with the relative consistent
level of total STAT2 (Fig. 3B).
Similarly, increased
level of STAT2
tyrosine phosphorylation was detected as well in IRF - 1 — transfected HT1080 cells (Fig. 4B).
