Transactivation assays of the promoters of GBSSI/SSIIIa and SSIIIa/SBEIIb by NF-YA1 and GATA9, respectively. a Diagram of the effector, reporter, and internal constructs; b Regulatory interaction between NF-YA1 and the promoter of GBSSI; c Regulatory interactions between NF-YA1/GATA9 and the promoter of SSIIIa; d Regulatory interaction between GATA9 and the promoter of SBEIIb. All data are means ± SD (n = 3). ** significant at p ≤ 0.01 by the Student’s t test
