MicroRNA: From Bench to Bedside provides an in-depth, expansive overview of microRNA from fundamentals to clinical practice. It provides researchers with a detailed insight into the topic of microRNA, exploring foundational knowledge followed by methodologies and the latest technologies for research, as well as potential theragnostic and therapeutic applications for specific diseases. This book consists of eight parts, beginning with an introduction to microRNA and the current state of the field, followed by sections on biogenesis and maturation of microRNA, and methodology and bioinformatics, where chapters focus on isolation and detection techniques. The book then moves on to molecular mechanisms and gene regulation, with chapters considering topics such as transcriptional regulation and epigenetic regulation, as well as the role of microRNA as biomarkers. Additionally, microRNA and human disease and microRNA-based therapeutics are explored, focusing on a wide range of diseases such as cancer, age-related disease, cardiovascular disease, microRNA targeted therapy in hepatitis and therapeutic strategies for diabetes. The book concludes with a discussion on advances and future perspectives in microRNA investigation.
