Identifying molecular targets is essential for several reasons: 1. Improved Diagnostics: Molecular targets can be used to develop more accurate diagnostic tests. For example, the presence of specific biomarkers can help in early detection of diseases. 2. Personalized Medicine: Understanding the molecular basis of a disease allows for the development of personalized treatment plans. This is particularly important in diseases like cancer, where treatment can be tailored based on the genetic profile of the tumor. 3. Drug Development: Molecular targets provide specific sites for drug action. Drugs designed to interact with these targets can be more effective and have fewer side effects.
