DNA Construct for Diagnosing and Treating Cancer

The present disclosure relates to a DNA construct, and a strain into which a recombinant vector comprising the DNA construct has been introduced. The DNA construct according to the present disclosure allows the expression levels of genes, operably linked downstream of first and second promoters, in a host strain or cell, to be balanced, so that cancer diagnosis and treatment may be performed simultaneously. In addition, the DNA construct of the present disclosure completely does not allow the anticancer protein and the reporter protein to be expressed at all in the absence of doxycycline, and thus it allows the anticancer protein to be expressed at an appropriate dose for cancer treatment by controlling whether or not treatment with doxycycline is performed, and at the same time, enables the size of the cancer to be monitored in real time depending on the expression level of the reporter protein.
