Provided are methods, compositions, and cells for use in adoptive cell therapy for the treatment of cancer. The methods involve administering an effective amount of cells to a subject, wherein the cells are modified ex vivo to suppress endogenous Zbtb20 expression and/or activity within the modified cells. The cells may comprise a dominant negative Zbtb20 capable of suppressing endogenous Zbtb20 activity, at least one shRNA capable of suppressing endogenous Zbtb20 expression, or at least one sgRNA capable of suppressing endogenous Zbtb20 expression. The cells may further comprise an exogenous TCR and/or CAR suitable for treating cancer. The method can further involve administering one or more additional cancer therapies, such as cells which express at least one exogenous TCR and/or CAR suitable for treating cancer. The method can provide various advantages, such as a reduction and/or elimination of an amount of cancer cells in the subject.
