Harnessing the thermogenic, energy-expending capacity of adipocytes has the potential to combat metabolic disorders. Although β-adrenergic receptor agonists are the best-known activators of thermogenesis, they carry considerable cardiovascular risks. A new study demonstrates the ability of G protein-coupled receptor 3 to intrinsically drive adipose thermogenesis independent of β-adrenergic receptor signalling.

The unique architecture of the liver consists of hepatic lobules, dividing the hepatic features of metabolism into 2 distinct zones, namely the pericentral and periportal zones, the spatial characteristics of which are broadly defined as metabolic zonation. R-spondin3 (Rspo3), a bioactive protein promoting the Wnt signaling pathway, regulates metabolic features especially around hepatic central veins. However, the functional impact of hepatic metabolic zonation, regulated by the Rspo3/Wnt signaling pathway, on whole-body metabolism homeostasis remains poorly understood.

The homeobox (HOX) family has shown potential in adipose development and function, yet the specific HOX proteins fueling adipose thermogenesis remain elusive. In this study, we uncovered the novel function of HOXC4 in stimulating adipose thermogenesis. Our bioinformatic analysis indicated an enrichment of Hoxc4 co-expressed genes in metabolic pathways and linked HOXC4 polymorphisms to metabolic parameters, suggesting its involvement in metabolic regulation.

Besides its thermogenic capacity, brown adipose tissue (BAT) performs important secretory functions that regulate metabolism. However, the BAT microenvironment and factors involved in BAT homeostasis and adaptation to cold remain poorly characterized. We therefore aimed to study brown adipocyte-derived secreted factors that may be involved in adipocyte function and/or may orchestrate intercellular communications.

Background: The prevalence of obesity and its associated diseases has sharply increased, becoming a global health issue. White adipose tissue (WAT), responsible for lipid storage via hyperplasia and hypertrophy, and brown adipose tissue (BAT), which facilitates energy dissipation, have increasingly been recognized as critical regulators of weight loss. Shouhui Tongbian Capsule (SHTB) has traditionally been used for detoxification, weight loss, and lipid reduction, and clinical evidence supports its use for relieving constipation.

Aims: Thermogenic adipocytes are able to dissipate energy as heat from lipids and carbohydrates through enhanced uncoupled respiration, due to UCP1 activity. PPAR family of transcription factors plays an important role in adipocyte biology. The purpose of this work was to characterize the role of PPARα and pemafibrate in the control of thermogenic adipocyte formation and function.
