BCA Protein Assay Reagent kit (Pierce, Rockford, IL, USA). Intracellular lipid contents, which were determined by the two methods just described, were normalized against the protein. Lipolysis assay 3T3-L1 cells were differentiated and treated with

carnitine palmitoyltransferase 1 (CPT1) activity and the subsequent activation of fatty acid oxidation ( Kahn et al . 2005 , Lopez et al . 2007 ). The decreased AMPK activity in visceral fat could enhance lipolysis as well as lipogenesis, although the

-induced activation of the SNS, which innervates the WAT, thereby reducing fat mass through stimulation of SNS-dependent lipolysis ( Haifei et al . 2009 ). Importantly, there is evidence that the activity of the melanocortin system is directly regulated by leptin and

.g. treatment of adipocytes causes an increase of UCP1 concentrations as well as an induction of lipolysis and subsequently a rise of free fatty acid (FFA) levels ( Collins et al . 2010 ). FFA themselves can further increase UCP1 activity, but they may also
