摘要:
In the present invention, as a result of detailed research into the expression, over-amplification, mutation and translocation, and the like of FGFR coding genes in a variety of cancer cells, a novel fusion polypeptide obtained by fusion of FGFR3 polypeptide with another polypeptide was identified and isolated in multiple urinary bladder cancer-derived cells and lung cancer cells. By using this fusion polypeptide as a biomarker in cancer therapy with an FGFR inhibitor, it is possible to preemptively prevent the manifestation of side effects in therapy with an FGFR inhibitor and control the therapeutic mode such that the best possible therapeutic results are obtained, and individualized medical treatment is possible.
摘要:
The present inventors successfully identified novel gatekeeper mutations for FGFR. Further, they discovered that mutant FGFR having the mutations demonstrate resistance to known FGFR inhibitors such as AZD4547, and at the same time demonstrate sensitivity to specific compounds. Mutant polypeptides having the mutations may be used as biomarkers in cancer treatment by FGFR inhibitors to prevent the development of side effects in therapy by conventional FGFR inhibitors, and to control the therapeutic mode for receiving the best therapeutic effect, thus making individualized treatment possible.
