Anti-obesity activity of OBEX is regulated by activation of thermogenesis and decreasing adiposity gain

The incidence of obesity has been increasing dramatically worldwide over the past decades, thus requiring novel and effective therapeutic approaches. OBEX is an oral nutritional supplement composed of antioxidants with antiobesity activity. The effects of OBEX have been tested in vivo and in vitro. In vivo, OBEX reduces weight gain by decreasing adiposity gain and increasing energy expenditure in high fat diet-fed mice through the activation of thermogenesis in brown adipose tissue (BAT) independent of eating behaviors. In vitro analysis with 3T3-F442A cells revealed anti-proliferative and anti-differentiation effects of OBEX. In addition, OBEX induced a clear reduction of the lipid load in mature adipocytes obtained from 3T3-F442A cells. Overall, our findings suggest that OBEX has a protective effect against an obesogenic environment This work has been partially supported by Catalysis S.L., CIBER Fisiopatología de la Obesidad y Nutrición (CIBERobn) (Grant CB06/0003 to F.F.C.), an initiative of the Instituto de Salud Carlos III of Spain which is supported by the regional development funding program (FEDER), Xunta de Galicia (Grant GRC2014/034 to F.F.C.), Instituto de SaludCaros III (Grant PI17/01287 to F.F.C.).
