title: Hodgkin's lymphoma cells are efficiently engrafted and tumor marker CD30 is expressed with constitutive nuclear factor-kappaB activity in unconditioned NOD/SCID/gammac(null) mice.
abstract: As there are very few reproducible animal models without conditioning available for the study of human B-cell-type Hodgkin's lymphoma (HL), we investigated the ability of HL cells to induce tumors using novel NOD/SCID/gammac(null) (NOG) mice. Four human Epstein-Barr virus-negative cell lines (KM-H2 and L428 originated from B cells, L540 and HDLM2 originated from T cells) were inoculated either subcutaneously in the postauricular region or intravenously in the tail of unmanipulated NOG mice. All cell lines successfully engrafted and produced tumors with infiltration of cells in various organs of all mice. Tumor cells had classical histomorphology as well as expression patterns of the tumor marker CD30, which is a cell surface antigen expressed on HL. Tumor progression in mice inoculated with B-cell-type, but not T-cell-type, HL cells correlated with an elevation in serum human interleukin-6 levels. Tumor cells from the mice also retained strong nuclear factor (NF)-kappaB DNA binding activity, and the induced NF-kappaB components were indistinguishable from those cultured in vitro. The reproducible growth behavior and preservation of characteristic features of both B-cell-type and T-cell-type HL in the mice suggest that this new xenotransplant model can provide a unique opportunity to understand and investigate the mechanism of pathogenesis and malignant cell growth, and to develop novel anticancer therapies.
