Hypothesis

Can new rat monoclonal antibodies against the human EGF receptor be effective for cancer therapy?

Conclusion

The study found that the new antibodies can inhibit the growth of human tumors that overexpress the EGF receptor.

Supporting Evidence

  • The antibodies inhibited the growth of several human tumor cell lines that overexpress the EGF receptor.
  • Three of the antibodies were of the IgG2b isotype, which is effective in activating human immune responses.
  • The antibodies did not cross-react with the c-erbB-2 proto-oncogene product.

Takeaway

Scientists created new antibodies that can stop cancer cells from growing by blocking a special receptor they need.

Methodology

The study involved producing rat monoclonal antibodies against the EGF receptor and testing their effects on various human tumor cell lines.

Limitations

The antibodies were less effective on certain tumor cell lines that secrete truncated forms of the receptor.
