Hypertrophy is a research area that focuses on the study of an increase in the size of cells or tissue as a result of increased workload or stimulation. This can occur in various tissues and organs of the body, such as muscle hypertrophy in response to exercise, cardiac hypertrophy in response to increased blood pressure, or liver hypertrophy in response to toxins. Researchers in this area study the cellular and molecular mechanisms underlying hypertrophy, as well as its implications for health and disease. By understanding hypertrophy, researchers aim to develop new treatments and interventions to target and manipulate cellular growth and function.
