By the T vector, the problem that the product of transcription or translation of exogenous genes by a strong promoter during blue-white selection of a vector might be toxic to host and cloning will fail can be overcome, blue-white selection of a vector might be toxic to host as a strong promoter starts transcription or translation; the defect that delection of 1-2 bp at enzyme digestion site leads to lacZalpha gene frameshift mutation and false positive clones are generated can be avoided; and the false negative phenomenon that a plate is full of blue stains because exogenous DNA fragment is small and insertion of exogenous DNA does not change a reading frame of lacZalpha gene can beeliminated.

The transcription factor NF-κB is activated in response to various stimuli including ionizing radiation. Disruption of NFκB activation by mutant forms of the NF-κB inhibitor IκB-α or by proteasome inhibitors enhances both sensitivity to radiation and radiation-induced apoptasis. The present invention shows that expression of a dominant negative fragment of human p65 (p65DN) leads to down-regulation of both endogenous p65 protein and its mRNA. The dominant negative protein also inhibits radiation-induced NF-κB activation by preventing the proteolysis of IκB-α, resulting in enhancement of cellular radiosensitivity and radiation-induced apoptosis. The region of p65 in the dominant negative fragment is thus a molecular target for disruption of NF-κB activation and sensitization of tumors to radiotherapy.
