Grants:

1. R01 CA177681  (Chen, Brantley-Sieders)   07/01/14-0/30/19   Ephrin-A1 in lipogenesis and breast cancer metastatic progression.

Our goal of this project is to determine how ephrin-A1 inhibits breast cancer metastasis and to test new drugs targeting EphA2 in subtypes of breast cancer that are refractory to existing therapies.

2. R01 CA95004   (Chen)    02/01/15-01/31/20
Endothelial mTOR signaling in tumor-blood vessel interaction

The aim of this project is to dissect the role of mTORC2 versus mTORC1 in tumor blood vessel, with the goal of developing mTORC2 as an alternative therapeutic target in cancer.

3. VA Merit Award  (Chen)   04/01/10-3/30/18   
Targeting EphA2 in lung cancer subtypes that are refractory to current therapy.

This study aims at dissecting the role of EphA2 receptors in KRAS and EGFR mutant lung cancer.
