The family member ELF3 was well expressed in the mRNA level in a subset of gastric cancers (n = 91), and its expression correlated with the expression of other transcription factors involved in gastric cancer pathogenesis, including HNF4A, HNF1A, CDX2, GATA4, GATA6, and EHF. The gene discussed is HNF1A; the disease is gastric cancer.
