Immunocompetent mice bearing 67NR syngeneic mammary carcinoma on bilateral flanks were treated with ionizing radiation at a single dose (2 or 6 Gy) to only one tumor, with or without concurrent use of Flt3-Ligand (Flt3-L) to enhance dendritic cell activation [25]. The gene discussed is FLT3LG; the disease is neoplasm.
