In conclusion, we found an increase in the Murf1 protein levels in gastrocnemius tissue of the direct model of obesity; as well, we observed an increase of the Murf1 in gastrocnemius and of the MAFbx in soleus muscles in the group of rats obese by programming and fed postnatally with a high-fat diet (doble stimulus). The gene discussed is FBXO32; the disease is Obesity.
