In the Correll Lab, our major research interests are the molecular processes that underlie the pathogenesis and progression of cardiac disease, with a focus on understanding a) how unfolded protein response (UPR) signaling and b) dysregulation of calcium handling control remodeling of the heart after acute injury or chronic stress. Our recent work identified that UPR signaling through the ATF6 transcription factor is essential for compensatory remodeling in response to hemodynamic stress, such as chronic hypertension. Ongoing studies in the Correll Lab seek to understand the cell-type specific ATF6 signaling that occurs during disease, as well as elucidate mechanisms that control ATF6 activation in the heart.
