About Edwin Posadas

Dr. Posadas’ research goal is to identify the molecular mechanisms of prostate cancer metastasis. A protein called FYN, which is a member of a cancer-causing gene family, was identified in his laboratory as a possible regulator of metastasis. The biology of metastasis is driven by molecular changes within cancer cells that enable cell motility, which contributes to the spread of cancer throughout the body. Analysis of prostate cancer tumor specimens showed that there were higher levels of FYN in cancer cells as compared to normal cells. Dr. Posadas will comprehensively define the function of FYN in prostate cancer cells. These studies may lead to the development of novel targeted therapies that block FYN function and prevent prostate cancer metastasis and cases of advanced prostate cancer in patients.
