STAT3 is constitutively activated in several cancers, including prostate cancer, and is therefore, a potential target for cancer therapy. DU-145 prostate cancer cells were stably co-transfected with STAT3 reporter and puromycin resistant plasmids to create a stable STAT3 reporter cell line that can be used for high throughput screening of STAT3 modulators. The applicability of this cell line was tested with two known activators and inhibitors of STAT3. As expected, EGF and IL-6 increased STAT3 reporter activity and enhanced the nuclear localization of phosphorylated STAT3 (pSTAT3); whereas Cucurbitacin I and AG490 decreased STAT3 reporter activity dose and time-dependently and reduced the localization of pSTAT3 in the nuclei of prostate cancer cells. Given the importance of STAT3 in cancer initiation and progression, the development of a stable STAT3 reporter cell line in prostate cancer cells provides a rapid, sensitive, and cost effective method for the screening of potential STAT3 modulators.
