Hypothesis

Can trefoil factor 3 (TFF3) serve as a novel serum marker for high-grade endometrial carcinomas?

Conclusion

TFF3 is highly expressed in high-grade endometrial carcinomas and may be a useful serum marker for early detection and monitoring.

Supporting Evidence

  • TFF3 was the top differentially expressed gene among 363 upregulated genes in G3-EEC compared to normal endometrium.
  • TFF3 serum levels were significantly higher in G3-EEC patients compared to healthy controls and patients with endometrial hyperplasia.
  • Immunohistochemistry showed TFF3 protein was significantly more expressed in G3-EEC compared to normal endometrium.

Takeaway

This study found that a protein called TFF3 is much higher in the blood of women with a certain type of cancer, which could help doctors find and track the disease better.

Methodology

Gene expression profiling was performed using microarrays, followed by validation with qRT-PCR and immunohistochemistry, and serum TFF3 levels were measured using ELISA.

Limitations

Further investigations on a wider set of samples are warranted to validate TFF3 as a serum marker.

Participant Demographics

Patients included 25 with G3 endometrial cancer, 42 healthy controls, and 13 with endometrial hyperplasia.
