摘      要：Promoting white adipose tissue(WAT)browning and enhancing brown adipose tissue(BAT)activity are attractive therapeutic strategies for obesity and its metabolic *** sympathetic innervation in WAT and BAT represents a promising therapeutic ***,there are few reports on extracellular microenvironment remodeling,especially changes in nerve terminal *** the key molecules mediating the neuro-adipose synaptic junctions is a key *** this study,we used bioinformatics methods to identify the differentially expressed predicted secreted genes(DEPSGs)during WAT browning and BAT *** DEPSGs largely reflect changes of cytokines,extracellular matrix remodeling,vascularization,and adipocyteneuronal *** then performed functional enrichment and cellular distribution specificity *** upregulated and downregulated DEPDGs during WAT browning displayed a distinctive biological pattern and cellular *** listed a cluster of adipocyte-enriched DEPSGs,which might participate in the cross-talk between mature adipocytes and other cells;then identified a synaptogenic adhesion molecule,Clstn3,as the top gene expressed enriched in both mature white and brown *** Q-PCR and immunohistochemistry,we found significantly increased Clstn3 expression level during WAT browning and BAT activation in mice subjected to cold exposure(4℃).We further demonstrated that treatment with isoproterenol significantly increased Clstn3 and UCP1 expression in differentiated white and beige adipocytes in *** conclusion,our study demonstrates that the secretion pattern was somewhat different between WAT browning and BAT *** reveal that Clstn3 may be a key gene mediating the neuro-adipose junction formation or remodeling in WAT browning and BAT activation process.
