Lung cancer-derived EGFR mutants exhibit intrinsic differences in inhibitor sensitivity
03-12-2007 · EurekAlert!A new study sheds light on how some small-molecule tyrosine kinase inhibitors, including two that are currently being used clinically to treat cancer, interact with wild-type and mutated forms of the epidermal growth factor receptor (EGFR).

- Gene analysis might explain ethnic differences in sensitivity to chemotherapy in lung cancer
04-23-2007 · UT Southwestern Medical Center
Analysis of three genetic mechanisms that cause non-small cell lung cancer might explain why East Asians respond better than other ethnic groups to a certain type of chemotherapy, a team led by UT Southwestern Medical Center researchers has found.

- New antibody for EGFR causes lung cancer regression
01-25-2007 · EurekAlert!
Mutant forms of the protein EGFR are involved in lung cancer development in many individuals, but not all individuals express the same mutant EGFR. A new study shows that both a mouse EGFR-specific antibody (mAb806) and its humanized form (ch806) cause lung tumor regression in two mouse models of lung cancer, leading to the suggestion that ch806 might provide a new approach to treat patients with lung cancer driven by mutant forms of EGFR.

- Gene variations point to why lung cancer drugs work better in Japanese vs. US patients
06-02-2007 · EurekAlert!
Recent clinical trials revealed that Japanese lung cancer patients survived longer and had a higher rate of side effects than US patients taking the same two drugs, paclitaxel and carboplatin. Now a new study by the Southwest Oncology Group uncovers genetic differences that may explain why. The results, embargoed for release 8:30 a.m. ET Saturday, June 2, are being highlighted at the American Society of Clinical Oncology annual meeting.

- New protein inhibitor impedes growth of cancerous cells
02-08-2007 · EurekAlert!
Researchers have developed a small-molecule inhibitor of a protein that plays key roles in the control of cell division, and they show that the inhibitor can halt the growth of tumors in mice and cancer-derived cells growing in culture.

- DMP1 deletion cooperates with oncogenic K-ras in lung cancer
10-15-2007 · EurekAlert!
Scientists have identified the transcription factor DMP1 as a pivotal tumor suppressor for both human and mouse lung cancers, especially in carcinomas that exhibit intact Arf-p53 pathways. The research, published by Cell Press in the October 2007 issue of Cancer Cell, may lead to development of new drug therapies for lung cancer.

- Novel EGFR antibody outperforms cetuximab in mouse model of lung cancer
01-26-2007 · EurekAlert!
A study conducted at the Dana-Farber Cancer Institute and the Ludwig Center at Dana-Farber/Harvard Medical School now suggests that antibodies binding a particular protein conformation, caused by hyperactivation, might have distinct therapeutic advantages over antibodies, like cetuximab, that bind to wild-type (normal) target proteins.
