A disease that transcends all races is breast cancer, the second leading cause of death among women with cancer. One factor, which participates in breast tumor progression, is the extracellular matrix (ECM), an acellular, protein-rich entity, which drives several cell, processes shown to promote tumorigenesis. Specifically, abnormal expression patterns and cross-linking of matrix fibers induces a more dense tissue structure, which has been reported to drive breast cancer progression. Alterations in ECM expression and cross-linking are in part due to carcinoma-associated fibroblasts (CAFs), activated fibroblasts which deposit copious ECM in the breast tumor environment. The goal of this study is …

Acute myocardial infarction (MI) remains a leading cause of morbidity and mortality worldwide. Accompanying MI is myocardial ischemia/reperfusion (MI/R) injury, which results in cardiac contractile dysfunction and additional myocardial cell death. MI/R injury is initiated in part by mitochondrial-derived reactive oxygen species due to mitochondrial membrane potential collapse and uncoupling of the electron transport chain, which may be due to mitochondrial fission in MI/R. Mitochondrial fission is in turn associated with shortening/fragmentation of mitochondria, decreased ATP production, and is thought to promote cardiac contractile dysfunction and post-reperfused cardiomyocyte loss, leading to increased infarct size. Therefore, inhibiting mitochondrial fission may be …
