Anderson Lab

  • Research in the Anderson laboratory focuses on cellular signaling and ionic mechanisms that cause heart failure, arrhythmias and sudden cardiac death, major public health problems worldwide. Primary focus is on the multifunctional Ca2+ and calmodulin-dependent protein kinase II (CaMKII). The laboratory identified CaMKII as an important pro-arrhythmic and pro-cardiomyopathic signal, and its studies have provided proof of concept evidence motivating active efforts in biotech and the pharmaceutical industry to develop therapeutic CaMKII inhibitory drugs to treat heart failure and arrhythmias. Under physiological conditions, CaMKII is important for excitation-contraction coupling and fight or flight increases in heart rate. However, myocardial CaMKII is excessively activated during disease conditions where it contributes to loss of intracellular Ca2+ homeostasis, membrane hyperexcitability, premature cell death, and hypertrophic and inflammatory transcription. These downstream targets appear to contribute coordinately and decisively to heart failure and arrhythmias. Recently, researchers developed evidence that CaMKII also participates in asthma. Efforts at the laboratory, funded by grants from the National Institutes of Health, are highly collaborative and involve undergraduate assistants, graduate students, postdoctoral fellows and faculty. Key areas of focus are: • Ion channel biology and arrhythmias • Cardiac pacemaker physiology and disease • Molecular physiology of CaMKII • Myocardial and mitochondrial metabolism • CaMKII and reactive oxygen species in asthma Mark Anderson, MD, is the William Osler Professor of Medicine, the director of the Department of Medicine in the Johns Hopkins University School of Medicine and physician-in-chief of The Johns Hopkins Hospital.
