Cellular and molecular endocrinology examines the cell science and atomic structure of hormones and their endocrine glands. Cellular and molecular endocrinology research focuses on bone metabolism, thyroid issues, calcium's role in atherogenesis, and muscle metabolism. This talk will go through DNA technology and its applications in a variety of sectors. The main purpose of this session is to share the most recent techniques and discoveries in cellular and molecular endocrinology and apply them to endocrine issues.
