For example, ApoA1 exerts an essential role in ovarian physiology and ovarian steroidogenesis (Bogan and Hennebold, 2010) and indeed the levels of this apolipoprotein are remarkably decreased in both serum and ovarian tissue of patients suffering from ovarian cancer (Stavnes et al., 2014; Wegdam et al., 2014). The gene discussed is APOA1; the disease is ovarian cancer.
