Hypothesis

The study investigates the expression of cadherin and NCAM in small cell lung cancer cell lines and xenografts.

Conclusion

The study found that most small cell lung cancer tumors express both cadherin and NCAM, indicating their potential role in tumor invasion and metastasis.

Supporting Evidence

  • All but one of the examined tumors expressed both cadherin and NCAM.
  • Polysialylation of NCAM was found in 14 out of 18 NCAM expressing tumors.
  • The study is the first report of cadherin expression in a large panel of SCLC tumors based on immunoblotting.

Takeaway

This study looked at how certain proteins, cadherin and NCAM, are found in lung cancer cells, which might help us understand how these cancer cells spread.

Methodology

The study used immunoblotting to analyze the expression of cadherin and NCAM in cell lines and xenografts from small cell lung cancer tumors.

Limitations

The study does not clarify the functional differences between cadherin family members and the specific roles of NCAM isoforms.

Participant Demographics

Nineteen tumors established from 15 patients with small cell lung cancer were examined.
