ETS family members with the highest protein level of expression in many gastric cancer samples include ETV5, ETV4 and ETV3, while ELF2 and ELF3 had moderate to high levels of expression in all samples tested in the Human Protein Atlas but only in one of the two antibodies checked for each protein (Fig. 2B) [13]. The gene discussed is ELF2; the disease is gastric cancer.
