Corin levels are a topic of research primarily within the field of cardiology and cardiovascular medicine. Corin is a type II transmembrane serine protease that plays a critical role in regulating blood pressure and cardiac function. Research into corin levels focuses on understanding how alterations in corin expression or activity may contribute to conditions such as heart failure, hypertension, and other cardiovascular diseases. Studying corin levels may provide insights into potential diagnostic markers or therapeutic targets for these conditions.
