A new study conducted by researchers at the University of Toronto has revealed key insights into how muscle cells regulate the production and release of the hormone IGF2. IGF2, which stands for Insulin-like Growth Factor 2, is an important hormone for skeletal muscle growth and development. The research team used a combination of advanced imaging techniques and molecular genetics to gain insight into the IGF2 secretory pathway in muscle cells. They found that the secretory pathway of IGF2 is cell-specific and involves the calcium-dependent release of IGF2 from the cell. This discovery could lead to future studies on how to regulate IGF2 secretion in muscle cells, which could have implications for the treatment of muscle-related diseases.
