Results from chromatin immunoprecipitation (ChIP) assays showed increased binding of p65 and cJun but not (p)STAT3 on the promoter of Il1f9 gene in the tumor tissues compared with the normal lung tissues from KrasLSL‐G12D/+Lkb1fl/fl mice that were intranasally injected with Ad‐Cre or Ad‐Vec (Figure S1E,F, Supporting Information). Here, STAT3 is linked to neoplasm.
