Research Interests/Sub-Specialty

My current work focuses on the role of the MEK/ERK signaling pathway in the regulation of T-cell DNA methylation in lupus. DNA methylating enzymes, especially dnmt1, are in part regulated by MEK/ERK signaling. We are therefore developing a transgenic mouse line that overexpresses a dominant negative MEK in T cells. These mice show reduced dnmt1 expression and overexpression of the methylation-sensitive genes in T cells. In addition, female mice expressing dominant negative MEK develop anti-dsDNA antibodies that are lupus specific.
