Under physiological conditions, the body maintains glucose homeostasis through interorgan communication between metabolic organs. As is well known, this crosstalk is mediated by traditional hormones or metabolites. Recently, a new type of secreted factor called RNAkine has become increasingly prominent in regulating glucose homeostasis. They are secreted non-coding RNAs that are mainly transported from the origin cells to the target cells through extracellular vesicles (EVs), participating in interorgan communication. In this review, we summarized the various organs involved in glucose homeostasis and their inter-organ crosstalk, and emphasized the important role of RNAkines which is of great significance for both the prevention and treatment of type 2 diabetes mellitus (T2DM).
