Synopsis

In the chapter titled "Hepatokines and Their Role in Metabolic Regulation," authored by Assistant Professor Gönül Şeyda Seydel in the book "Current Biochemistry Studies II," the fundamental functions of the liver in systemic metabolism and energy homeostasis are comprehensively examined. Emphasizing that the liver is an endocrine organ that secretes specialized proteins called "hepatokines" capable of cellular communication with distant tissues; its modulating roles in glucose and lipid metabolism regulation, energy homeostasis, inflammation, obesity, insulin resistance, type 2 diabetes, and non-alcoholic fatty liver disease (NAFLD) development are explained in detail. The study addresses the action mechanisms of key hepatokines—including Activin E, Angiopoietin-Like Protein 4 (ANGPTL4), Fetuin-A, Fetuin-B, Fibroblast Growth Factor 21 (FGF21), Follistatin, Hepassocin, Leukocyte Cell-Derived Chemotaxin 2 (LECT2), Selenoprotein P, and Tsukushi (TSK)—along with their cellular responses to physiological conditions such as feeding, fasting, and exercise. Furthermore, it is highlighted that altered hepatokine expression levels serve as potential biomarkers for the early detection of metabolic dysfunctions, and that unraveling inter-organ communication pathways plays a critical role in developing novel therapeutic strategies. This chapter offers a scientifically profound review suitable for featuring on book promotion platforms, catering to researchers and readers aiming to understand the molecular foundations of metabolic diseases.
