Hypothesis

E-selectin activation of Death receptor-3 enhances colon cancer cell survival through the PI3K-NFκB pathway.

Conclusion

E-selectin activation of DR3 leads to increased survival of colon cancer cells by activating the PI3K/NFκB pathway.

Supporting Evidence

  • E-selectin interacts with Death receptor-3 on colon cancer cells.
  • Activation of the PI3K/Akt pathway was observed following E-selectin treatment.
  • Inhibition of PI3K increased apoptosis in colon cancer cells treated with E-selectin.
  • Metastatic colon cancer cells express a splice variant of DR3 that lacks a death domain.

Takeaway

E-selectin helps colon cancer cells stick to blood vessels and survive by turning on a special survival signal inside the cells.

Methodology

The study used cell survival assays, apoptosis assays, and PCR to investigate the effects of E-selectin on colon cancer cells.

Limitations

The study primarily focuses on specific colon cancer cell lines and may not represent all colon cancer types.
