ELL-associated factors 1 and 2 (EAF1/2), a class of tumor suppressor genes interacting strongly with eleven-nineteen lysine-rich leukemia (ELL), can inhibit a variety of cancers in organisms, including leukemia and prostate cancer (Heydaran et al. 2021; Kenner 2014; Polak et al. 2003; Simone et al. 2003). The gene discussed is EAF1; the disease is prostate cancer.
