Research Interest:

My primary research interest is the study of the specific cellular and molecular processes underlying the control of endocrine cell secretion. Two important cell models, prolactin secreting cells of the anterior pituitary and gonadotropic hormone releasing hormone (GnRH)-secreting neurons of the hypothalamus are used in investigations in the laboratory. Our use of these cells in conjunction with a recently developed promoter driven luciferase detection system enables us to study, in real-time, prolactin or GnRH gene expression at the level of the single cell. Our findings with this approach, when coupled with other single cell fluorescent techniques such as measurement of exocytotic release or measurement of changes in intracellular calcium have provided a great deal of insight on the interplay of nuclear and cytoplasmic processes that are critical to the control of hormone secretion. Information from our studies is not only important for understanding of multiple facets of endocrine function in individual cells, but also provides an awareness of various aspects of gene expression that are fundamental to the control of all cells, endocrine and non-endocrine alike.
