タイトル Expression of a chemokine BRAK/CXCL14 in oral floor carcinoma cells reduces the settlement rate of the cells and suppresses their proliferation in vivo.
ジャーナル Biomed Res
Abstract We reported previously that the forced expression of the chemokine BRAK/CXCL14 in head and neck squamous cell carcinoma cells decreased the rate of tumor formation and size of tumor xenografts in athymic nude mice and SCID mice. In order to clarify the expression of BRAK/CXCL14 affected either the settlement of carcinoma cells in host tissues in vivo or proliferation of the colonized carcinoma cells or both, we prepared oral floor carcinoma-derived HSC-2 cells in which BRAK/CXCL14 expression was induced upon doxycycline treatment. Then 30 nude mice were separated into 3 groups composed of 10 mice per group: Group I, the control, in which the engineered cells were directly xenografted onto the back of the mice; Group II, the cells were xenografted and then the mice were treated with doxycycline; and Group III, the cells were pretreated with doxycycline during culture, and the host mice were also treated with the drug before and after xenografting. The effects of BRAK/CXCL14 expression were examined by measuring the tumor size. The order of the size of tumor xenografts was Group I > II > III, even though the growth rate of the engineered cells was the same whether or not the cells were cultured in the presence of the drug. In addition, the size of tumors was significantly down-regulated after xenografting the doxycycline-pretreated cells in Group III. These data indicate that BRAK/CXCL14 expression in oral floor carcinoma cells reduced both the rate of settlement and the proliferation of the cells in vivo after settlement of the cells.
