Heart disease is the leading cause of death in this country. At the moment, the only way to effectively replace lost heart muscle cells—called cardiomyocytes—is to transplant the entire heart. We think using a drug to create new heart muscle from stem cells would be far more appealing than heart transplantation.
Dr. Mercola's research is directed at discovering new therapeutics for heart failure and cancer.

Mark Mercola's Research Focus
Heart Disease, Cancer
Our lab seeks to enable new treatments for heart disease and cancer, both of which remain major causes of mortality and morbidity despite intense research efforts. For heart disease, our emphases are on maintaining contractility and stimulating regeneration during heart failure. Some of our recent advances include the discovery of microRNAs that impair cardiac function during failure, and the demonstration that inhibiting one particular microRNA using a therapeutic RNA molecule can halt the progression of heart failure symptoms in a mouse model. Another example is a small molecule that directs cardiac progenitor cells to form new heart muscle cells. For cancer, our focus has been on developing small molecules that target the control of cell division. One example is a highly potent small molecule that targets a single protein to simultaneously stabilize p53 and inhibit Wnt/β-catenin signaling, and has promising effects against colon cancer in an animal model.
Our strategy is to model complex disease processes in vitro, and then to apply use high throughput functional genomics and chemical biology approaches to identify potential drug targets. A major emphasis of the lab has been to work with the Conrad Prebys Center for Chemical Genomics and Vala Sciences (San Diego) to develop and apply new optical screening technologies for image-based analysis of disease processes. This collaboration has led to instrumentation, software and stem cell-based assays for high throughput study of physiology such as muscle contraction and neuronal impulse propagation. Through such technological advances we hope to gain insights into basic disease mechanisms that will enable the development of novel therapeutics.
