This study helps to fill a remaining knowledge gap surrounding the mechanisms and pathways that contribute to cardiomyopathies in SCD. A better understanding of the pathophysiological mechanisms could lead to more accurate therapeutic targets to improve quality of life as well as life expectancy. In this study I recapitulate cardiac dysfunction in vitro by exposing engineered mouse cardiac tissues to ANG II or the sickled microenvironment. Experimental results include gene expression profiles and oxidative stress generation. Gene expression profiles in the ANG II treated tissues indicated a pathological state with upregulation in biomarkers for inflammation, cell adhesion, wall stress and ECM related genes. Further research is being conducted using insights gained from this study which will lead to a broader understanding of the biological processes involved and potentially identify novel therapeutic targets that may ultimately improve patient outcomes.
