The book "Peroxisome Proliferator-Activated Receptors (PPARs)" provides a comprehensive examination of the three subtypes of peroxisome proliferator-activated receptors (PPARs), which play a crucial role in various physiological and pathophysiological processes. The authors, renowned experts in the field, present detailed protocols for studying these receptors. The chapters cover a wide range of methods, from cloning the receptors to their knockdown and the investigation of post-translational modifications. Additionally, the subcellular localization of the receptors and their impact on behavioral functions are discussed, representing an emerging area of research. The book is written in the established format of the "Methods in Molecular Biology" series and offers a structured approach to the topic, including introductions, material lists, step-by-step protocols, and troubleshooting tips.
