Hypothesis

Can substituted trans-stilbenes inhibit or enhance the TPA-induced activation of activator protein-1 (AP-1)?

Conclusion

Trans-stilbenes can inhibit or enhance the effects of TPA without relying on their anti-oxidant properties.

Supporting Evidence

  • Several trans-stilbenes were identified that inhibit TPA-induced activation of AP-1, with IC50 values as low as 0.5 μM.
  • Some trans-stilbenes enhanced the effects of TPA 2 to 3-fold.
  • Many identified trans-stilbenes are devoid of anti-oxidant properties.

Takeaway

Some plant compounds can either help or hurt a specific protein's activity in cells, and this doesn't depend on whether they are antioxidants.

Methodology

A library of substituted trans-stilbenes was screened using the Panomics AP-1 Reporter 293 Stable Cell Line to assess their effects on TPA-induced AP-1 activation.

Limitations

The study did not identify the specific targets of the trans-stilbenes affecting AP-1 activity.
