Figure S3 from Oncogenic KRAS Confers Chemoresistance by Upregulating NRF2

Figure S3. Identification of a TRE (TGCGTCA) in the promoter of NRF2. The different human NRF2 promoter constructs were cloned upstream of a luciferase reporter gene (the sites where primer pairs bind are illustrated). These constructs were co-transfected into HEK293 cells alone with an empty vector, KRASDN, KRASG12D or KRASWT expression vector for 48h. Dual luciferase activities were measured. The experiment was repeated three times, each with triplicate samples. Data are expressed as mean {plus minus} SEM (*p < 0.05 Ctrl group vs. KRAS) (left panel).
