The STAT3 Leeporter™ GFP Reporter cell line is a stably transfected HEK293 cell line, which expresses enhanced green fluorescent protein (eGFP) reporter gene under the transcriptional control of the STAT3 responsive promoter, so that the cell line is designed to measure the transcriptional activity of STAT3. As a transcription factor, Signal Transducer and Activator of Transcription 3 (STAT3) is activated through phosphorylation at tyrosine 705 in response to various cytokines including IL-6, interferons, epidermal growth factor, hepatocyte growth factor and leukemia inhibitory factor. The phosphorylated STAT3 forms homodimers or heterodimers with STAT1, and the dimers translocate to nucleus in which DNA binding/promoter induction occurs. The cell line is designed to analyze by fluorescence microscopy and flow cytometry. The STAT3 induction by IL-6 is shown in Figures 1 and 2.

Application:

Monitor the STAT3 signaling pathway activity.
Screen for activators or inhibitors of the STAT3 signaling pathway.

Culture conditions:

Cells should be grown at 37^oC with 5% CO₂ using DMEM medium (w/ L-Glutamine, 4.5g/L Glucose and Sodium Pyruvate) supplemented with 10% heat-inactivated FBS and 1% Pen/Strep, plus 3 µg/ml of Puromycin (Note: Puromycin can be omitted during the reporter cell assays).

It is recommended to quickly thaw the frozen cells upon receipt or from liquid nitrogen in a 37^oC water-bath, transfer to a tube containing 10 ml of growth medium without Puromycin, spin down cells, resuspend cells in pre-warmed growth medium without Puromycin, transfer resuspended cells to T25 flask and culture in 37^oC-CO₂ incubator.

Leave the T25 flask in the incubator for 1~3 days without disturbing or changing the medium until cells completely recover viability and become adherent. Once cells are over 90% adherent, remove growth medium and passage the cells through trypsinization and centrifugation. At first passage, switch to growth medium containing Puromycin. Cells should be split before they reach complete confluence.

To passage the cells, detach cells from culture vessel with Trypsin/EDTA, add complete growth medium and transfer to a tube, spin down cells, resuspend cells and seed appropriate aliquots of cells suspension into new culture vessels. Subcultivation ration = 1:10 to 1:20 weekly. To achieve satisfactory results, cells should not be passaged over 16 times.

Functional validation:

A. Response of STAT3 Leeporter™ GFP reporter – HEK293 cells to IL-6.

1. Harvest STAT3 Leeporter™ GFP reporter – HEK293 cells and seed cells into a tissue culture plate (e.g. 96-well plate in 100 ul of growth medium at 5 x 10^4 cells/well, 24-well plate in 500 ul of growth medium at 2.5 x 10^5 cells/well, 12-well plate in 1 ml of growth medium at 5 x 10^5 cells/well, or 6-well plate in 2 ml of growh medium at 1 x 10^6 cells/well.

2. Incubate cells at 37^oC in a CO₂ incubator for overnight.

3. The next day, stimulate cells with different concentrations of IL-6.

4. Incubate at 37^oC in a CO₂ incubator for 6-16 hours.

5.Analyze cells through fluorescence microscopy or flow cytometry.
