Adenocarcinoma

Dr. Cote is examining the role of estrogen-related tumor characteristics in predicting differences in survival between men and women after a lung cancer diagnosis. The identification of molecular and genetic profiles associated with survival will help target treatment advances and customize treatment for male and female lung cancer patients.

Dr. Klinge is studying why there is a gender bias in lung adenocarcinoma that results in women being at higher risk for developing it. Her studies have revealed which proteins are expressed differently by gender in lung adenocarcinoma cells and how they could be targets of therapy in lung adenocarcinoma.

In order to identify mutated genes that cause lung cancer, Dr. Starr has developed a system that is capable of randomly mutating genes within cells, resulting in tumor formation. The genes mutated by this method can easily be identified using standard molecular biology techniques. He can then test their role in lung cancer formation. 

The Hedgehog (Hh) signaling pathway is active in both small cell and non-small cell lung cancer and provides a “don’t stop growing” signal to cancer cells. Dr. Robbins is working to identify and validate a panel of biomarkers that can be used to determine whether the lung cancer is sensitive to drugs that stop Hh signaling.

Dr. Kim’s hypothesis is that bronchioloalveolar carcinomas, a subtype of non-small cell lung cancer, are maintained by a small population of cells often referred to as cancer stem cells. Dr. Kim is identifying these stem cells and drugs that inhibit them.

The role of the hormone estrogen in the development of lung cancer has been established. Dr. Heymach is studying how estrogen affects signaling by the EGFR gene and secretion of proteins that fuel the development of new blood vessels necessary to sustain the growth of the cancer.

NNK is a powerful nicotine-derived carcinogen. Dr. Schuller is determining the exact role of estrogen in tumors caused by NNK. This understanding will provide new targets for the early diagnosis, prevention, and therapy of lung cancer in women.

Dr. Baldwin is identifying and testing new therapeutic targets for KRAS-positive lung cancer. KRAS activates the factor NF-κβ, which, when abnormally active, can contribute to the growth of lung tumors. This activation involves two kinases, and well-validated inhibitors of these pathways exist. This project is determining whether these inhibitors will block the initiation and/or progression of lung tumors.

The IDO protein stops immune cells from recognizing cancer cells and mounting an attack against the cancer. Dr. Prendergast is determining how the IDO protein works in non-small cell lung cancer cells that have mutations in the KRAS gene. He is also testing new compounds that can inhibit IDO in non-small cell lung cancer.

Genes that can suppress the development of tumors are often lost or silenced during the development of human lung tumors. Because they function as a “brake” that normally prevents the onset of lung tumors, they provide new targets for the development of replacement therapies for the effective treatment of lung cancers. Dr. Lisanti is testing the effectiveness of the replacement of a novel tumor suppressor gene, caveolin-1.
