Preliminary experiments revealed vastly different levels of LEPR expression in a group of Grade 3 ovarian tumors (Supplementary Figure 1A) that was confirmed in a panel of 52 cell lines representing a range of different ovarian cell sub-types (Supplementary Figure 1B) and in 484 ovarian cancer samples (Supplementary Figure 2). The gene discussed is LEPR; the disease is ovarian carcinoma.
