High fat diet administration leads to the mitochondrial dysfunction and selectively alters the expression of class 1 GLUT protein in mice

Metabolic syndrome is an agglomeration of disorders including obesity, diabetes and cardiovascular diseases and characterized as chronic mild inflammation which elevates the circulatory inflammatory markers. This could be due to mitochondrial dysfunction, oxidative stress and hypoxia as a consequence of high fat diet (HFD) intake. The present study focuses on the effects of HFD on lactate and mitochondrial metabolism as well as tissue dependent changes in glucose transporter (GLUT) expression in liver, skeletal muscles and adipose tissue of mouse. Lactate dehydrogenase (LDH) and mitochondrial dysfunction established the link between the occurrences of metabolic stress due to HFD. In this work, it was observed that chronic HFD administration aggravated the metabolic alterations by causing reduced ATP production, imbalanced oxidative stress and altered class 1 GLUTs expression. Chronic HFD significantly reduced (p
