The overall theme of research in our laboratory is to study signal transduction within eukaryotic cells. We are particularly interested in elucidating the functions of protein kinases and nuclear receptors which are deregulated in human prostate cancer, namely Src, Etk/BMX, Pim-1 and androgen receptor. We and others demonstrated that deregulation of these signaling molecules may play an important role in development of therapeutic resistance in human prostate cancers. Studying the mechanisms by which these proteins regulate their downstream signaling effectors in cancer models will allow us to design new effective drugs against cancer in the future.
