Abstract: Disclosed herein are systems and methods for evaluating a protein of interest on growth inhibition of a tumor while following the tumor in vivo or in vitro through a co-expressed visible marker. The present disclosure provides an expression composition for stably transforming cells, preferably tumor cells. The expression composition includes two vectors respectively include polynucleotides encoding a protein of interest and a visible marker, wherein each polynucleotide is operably linked to a tet-on system such that the protein of interest and the visible marker are co-expressed upon activation of the tet-on system. The present disclosure also provides stably transfected cell lines, which may be used to access real-time biological processes, including tumor cell proliferation.
