Themes<\/h2>\n

Nuclear receptors are part of a multigenic family of hormone-activated transcription factors that regulate target gene expression. Of interest is also their inherent ability of undergoing post-translational modifications in response to cellular kinase pathways. Two classes of receptors are studied in the laboratory:<\/p>\n

The estrogen receptors ER\u03b1 and ER\u03b2 mediate hormone responsiveness of reproductive and peripheral tissues, and are involved in diverse aspects of human reproduction, embryonic development, and physiology. Our interest relates to the role of upstream cellular signals that regulate ER functions.<\/p>\n

The PPARs (\u03b1, \u03b2, and g) are nuclear receptors involved in lipid homeostasis and energy metabolism. The regulation of lipogenic\/thermogenic target gene expression, the role of other nuclear receptors, such as LXR and FXR, and the mitochondrial activity and biogenesis are among the various aspects studied in the lab.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
