The TEAD Reporter - MCF7 cell line contains the firefly luciferase gene under the control of TEAD responsive elements stably integrated into the human breast cancer cell line, MCF7. Inside the cells, basal unphosphorylated YAP/TAZ remains in the nucleus and induces the constitutive expression of luciferase reporter. The cell line is validated for the inhibition of the expression of luciferase reporter by the activators of the Hippo pathway.
Mycoplasma testing: The cell line has been screened using the PCR-based VenorGeM Mycoplasma Detection kit (Sigma-Aldrich) to confirm the absence of Mycoplasma species.
Host Species: human
Supplied as Each vial contains ~1.5 X 10^6 cells in 1 ml of 10% DMSO.
Background
The Hippo pathway regulates cell proliferation and cell death. It is activated by high cell density and cell stress to stop cell proliferation and induce apoptosis. The mammalian Hippo pathway comprises MST kinases and LATS kinases. When the Hippo pathway is activated, MST kinases phosphorylate LATS kinases, which phosphorylate transcriptional co-activators YAP and TAZ. Unphosphorylated YAP and TAZ remain in nucleus and interact with TEAD/TEF transcriptional factors to turn on cell cycle-promoting gene transcription. However, when phosphorylated, YAP and TAZ are recruited from the nucleus to the cytosol, so that the YAP and TAZ-dependent gene transcription is turned off. Dysfunction of the Hippo pathway is frequently detected in human cancer and its down-regulation correlates with the aggressive properties of cancer cells and poor prognosis.
Application
Monitor Hippo pathway activity. Screen for activators or inhibitors of the Hippo pathway.
