Lycopene Effects on Metabolic Syndrome and Kidney Injury in Rats Fed a High-Fat Diet: An Experimental Study

Area of Science:

• Biochemistry
• Nutrition
• Toxicology

Background:

• Global rise in overweight and obesity correlates with cardiovascular, metabolic, and diabetes mellitus disorders.
• Lycopene (Lyc), an antioxidant, shows therapeutic potential.
• Metabolic syndrome and kidney damage are significant health concerns linked to obesity.

Purpose of the Study:

• To investigate the effects of lycopene on metabolic syndrome and kidney damage in rats fed a high-fat diet (HFD).
• To evaluate lycopene's impact on oxidative stress, inflammation, and apoptosis in the kidneys.

Main Methods:

• Rats were divided into five groups: control, HFD, HFD with two doses of lycopene, and HFD with simvastatin.
• Kidney tissues were analyzed for biochemical parameters, oxidative stress markers (LPO, PC, GSH, thiol), antioxidant enzymes (SOD, CAT, GPx, GR), Nrf2 mRNA expression, inflammatory markers (TNF-α, IL-1β, NF-κB), and apoptotic markers (Bax, Bcl-2).

Main Results:

• HFD significantly increased body weight, glucose, uric acid, creatinine, lipid peroxidation, protein carbonyl, inflammatory markers, and apoptosis markers compared to controls.
• HFD led to decreased Nrf2 mRNA expression and reduced activity of key antioxidant enzymes in the kidneys.
• Lycopene treatment effectively reversed the detrimental effects of the HFD, improving biochemical parameters and reducing oxidative stress and inflammation.

Conclusions:

• Lycopene consumption effectively mitigates high-fat diet-induced metabolic syndrome and kidney damage in rats.
• Lycopene exhibits protective effects against obesity-related renal dysfunction through antioxidant and anti-inflammatory mechanisms.
• Lycopene represents a promising therapeutic agent for preventing and treating metabolic disorders and associated kidney damage.
