As shown in Figure 1, high expression of Beclin 1 is mainly found in normal lung tissues, manifesting the large number of samples with group 3 (74 of 216, 34.3%, Figure 1D) and group 4 (93 of 216, 43.1%, Figure 1D), whereas lung tumor tissues, regardless of tumor subtypes, showed moderate Beclin 1 staining (Figure 1A, B, D). The gene discussed is BECN1; the disease is neoplasm.
