Background
Poor dietary habits such as an over consumption of high fructose and high fat diet are considered as the major culprit for the induction of diabetes associated liver injury. Diabetes mellitus is a metabolic disorder that affects various vital organs of the body especially the kidney, brain, heart, and liver. The high fructose and high fat (HFHF) diet worsen the metabolic conditions by producing various pathogenic burdens such as oxidative stress, inflammation, etc. on liver. The hyperlipidemic and hyperglycemic conditions induced by HFHF diet leads to the generation of various proinflammatory mediators like TNFα, interleukin and cytokines.
Aim and methods
The systematic bibliographical literature survey was done with the help of PubMed, Google scholar and MedLine to identify all pathological and molecular concerened with HFHF induced diabetic liver injury. The consumption of HFHF diet leads to an increase in mitochondrial oxidative stress thereby decreases the liver protective antioxidants required for cell viability. HFHF diet disturbs lipid and lipoprotein clearance by elevating the level of apolipoprotein CIII and impairing the hydrolysis of triglyceride. As a result, there is an increase in free fatty acid concentration, triglycerides and diacylglycerol in the liver which further triggers the situation of insulin resistance.
Conclusion
The focus of present review is based upon the various pathological, genetic and molecular mechanism involved in the development of high-fat high fructose diet induced diabetic liver injury. However, the current review also documented few shreds of evidence related to various microRNAs (miR-31, miR-33a, miR-34a, miR-144, miR-146b, miR-150) concerned to HFHF diet which play an important role in the pathogenesis of diabetes associated liver injury Dietary life style modification may prove beneficial in the management of various metabolic disorders.
