The specific disease focus of my current research includes: (i) Improvement in breast cancer adjuvant therapy (ii) Early detection of breast and ovarian cancer (iii) New approaches to treating proliferative disorders of the prostate (iv) Molecular approaches to targeted drug delivery in acute myelogenous leukemia.
In recent years, we have discovered non-classical mechanisms of transcriptional regulation of genes by the nuclear receptor superfamily, including various steroid receptors and the retinoic acid receptor. The new findings have found broad implications in global gene regulation mechanisms and in the mechanism-based treatment of different cancers including breast cancer, ovarian cancer, prostate cancer and myelogenous leukemias. Our recent studies have shed new light on mechanisms underlying the progression of breast and prostate cancers and have identified possible ways of improving upon current therapies. In the foreseeable future, my laboratory's broad research interests will continue to expand into the molecular endocrinology of nuclear receptors while continuing to pursue our previous advanced studies of folate receptor-targeted therapeutics (see below).
In previous years, my laboratory pioneered the discovery and characterization of the folate receptor gene family and helped to establish the potential utility of FR isoforms in the targeted therapy of various types of cancer as well as inflammatory diseases. Those studies involved detailed investigations of structure-function and gene regulation of FRs. Our contributions to the field have supported more recent advances in the clinical arena where an explosion of various types of folate drug conjugates, immunotherapies, novel antifolates and nanoparticles are showing great promise as therapeutics for cancer and inflammatory diseases. We are now at a stage in which our additional ideas on the potential utility of FRs as serum markers for the early detection of ovarian, endometrial and breast cancers must be investigated in clinical studies.
