Therapeutics Award

Drs. Byers and Gibbons have discovered that lung cancer cells acquire the ability to hide from the immune system during epithelial-to-mesenchymal transition—a process through which cancer cells develop the ability to spread to other parts of the body (metastasis). The LUNGevity award will help Drs. Byers and Gibbons study the effect of a new drug that can reverse the EMT process and make lung cancer cells more visible to the immune system.

Surgery is often recommended for patients who have localized lung cancer. Dr. Bogolioubov is analyzing how fast lung cancer comes back after surgery to remove the primary tumor. He is also evaluating the role of chest CT radiography for post-operative follow-up.

Bexarotene is a synthetic form of retinoid acid (Vitamin A) that has the potential for use in lung cancer chemoprevention. Dr. Petty is conducting a clinical trial with a treatment combination of bexarotene and erlotinib (Tarceva) in EGFR-positive patients who have metastatic non-small cell lung cancer (NSCLC). He is also evaluating biomarkers that will predict response to the combination regimen.

Cancer cells develop resistance to chemotherapy drugs by 1) making proteins that neutralize the effects of chemotherapy (through a protein called Bcl-2) and 2) developing pumping systems that expel the drugs out of the cells (through a protein called MRP). Dr. Minko is studying how stopping the Bcl2 and MRP proteins will make lung cancer cells more sensitive to chemotherapy drugs.

Agents that activate the PPARgamma protein have already been used  in the treatment of diabetes and atherosclerosis. Dr. Keshamouni is researching whether and how they affect the growth of non-small cell lung cancer (NSCLC) cells.

Dr. Pao’s research may determine whether specific mutations in tyrosine kinase genes make lung tumors vulnerable to EGFR-TKIs. A comprehensive analysis of the tyrosine kinase in lung cancers could also lead to new opportunities for drug development and more personalized molecularly targeted therapies.

Angiogenesis is the process by which cancer cells recruit blood vessels to the tumor. This aids the growth of cancer cells by providing nutrition and oxygen to them. Dr. Vlahakis is studying how a protein called VEGF-A interacts with certain proteins expressed on the surface of lung cells to control the angiogenesis process.

Dr. Ma has identified mutations in the protein c-Met that may provide lung tumor cells the ability to metastasize. Dr. Ma is studying the role of c-Met and its genetic alterations in lung adenocarcinoma to better understand their functional implications.

Dr. González Santamaria is investigating how the degradation of certain tumor suppressors (genes that stop cancer development) is accelerated and how that of certain onco-proteins (proteins that cause cancer) is slowed down in lung tumors. Her research will provide a platform for predicting the outcome for lung cancer patients.

Fibroblasts are cells found in different tissues of the body, including lung tissue. Dr. Arenberg is studying differences in the types of proteins made by tumor-derived lung fibroblast cells and by normal lung fibroblast cells. With an understanding of which proteins make a tumor-derived fibroblast behave in such a way as to promote tumor growth and spread, there is potential to therapeutically target them.
