Duchenne muscular dystrophy (DMD) is a lethal X-linked disorder associated with dystrophin deficiency that results in chronic inflammation and severe skeletal muscle degeneration. In DMD mouse models and patients, we find that IkappaB kinase/NF-kappaB (IKK/NF-kappaB) signaling is persistently elevated in immune cells and regenerative muscle fibers. Ablation(More)
Activating transcription factor 3 (ATF3) is a member of the CREB/ATF family of transcription factors. Previously, we demonstrated that the expression of the ATF3 gene is induced by many stress signals. In this report, we demonstrate that expression of ATF3 is induced by cardiac ischemia coupled with reperfusion (ischemia-reperfusion) in both cultured cells(More)
Cell-cell and cell-matrix interactions play important regulatory roles in lymphocyte homeostasis. Thrombospondin-1 (TSP1) is a matricellular protein that differentially promotes the adhesion of resting and activated T cells. In this work, we show that adhesion of Jurkat T cells on substrates coated with TSP1 or TSP1-derived peptides is mediated by beta 1(More)
Rescue of dystrophic skeletal muscle in mdx and utrophin/dystrophin-deficient (dko) mouse models by reintroduction of dystrophin has validated gene therapy as a potential therapeutic approach for Duchenne muscular dystrophy. However, the size of the dystrophin gene exceeds the capacity of adeno-associated viral (AAV) vectors. Dystrophin provides a(More)
Membrane-associated guanylate kinases (MAGUKs) are cytoplasmic multi-domain proteins that serve as scaffold proteins at cell junctions and synapses. Calmodulin-associated serine/threonine kinase (CASK) stabilizes the integrity of synapses in the brain. Additionally, CASK is capable of acting as a transcriptional co-activator and localizes to neuronal nuclei(More)
