An emerging approach to the study of diseases is through an examination of molecular structures and mechanisms, identification of the molecular and genetic errors of disease, and the formulation of molecular interventions to correct these. This approach is what characterizes the field of molecular medicine. An understanding of disease pathogenesis at the molecular level and normal body functioning is crucial for the development of the field. It integrates the domains of molecular genetics and molecular biology for a comprehension of human health and disease. Some of its key focuses are cancer research, immunology, gene expression, proteins, biotechnology, etc. This book covers in detail some existing theories and innovative concepts revolving around molecular medicine. The various advancements in molecular medicine are glanced at and their applications as well as ramifications are looked at in detail. With state-of-the-art inputs by acclaimed experts of this field, this book targets students and professionals.
