Cancer immunotherapy is the use of the immune system to treat cancer.Our current research proposed an optional strategy of activating immune system involving in cancer immunotherapy.When being treated with 2% DMSO in culture medium,Hepa1-6 cells showed depressed proliferation with no signicant apoptosis or decreased viability.D-hep cells,Hepa1-6 cells treated with DMSO for 7 days,could restore to the higher proliferation rate in DMSO-free medium,but alteration of gene expression pro le was irreversible.Interestingly,tumors from D-hep cells,not Hepa1-6 cells,regressed in wild-type C57BL/6 mice whereas D-hep cells exhibited similar tumorigenesis as Hep1-6 cells in immunodecient mice.As expected,additional Hepal-6 cells failed to form tumors in the D-hep-C57 mice in which D-hep cells were eliminated.Further research con rmed that D-hep-C57 mice established anti-tumor immunity against Hepa1-6 cells.Our research proposed viable tumor cells with altered biological features by DMSO-treatment could induce anti-tumor immunity in vivo.
