Fig. 3From: Identification and functional study of GATA4 gene regulatory variants in type 2 diabetes mellitusRegulatory variants affect transcription factor binding. EMSA was performed with biotin-labeled oligonucleotide (30 bp) containing regulatory variants and nuclear extracts (HEK-293 and INS-1 cells). Transcription factor binding is indicated with an open arrow. 293, HEK-293. WT, wild type. RV, regulatory variantBack to article page
