Vitisin A Inhibits MAPK and NF-κB Signaling Pathways and Improves Renal Function in LPS-Induced Acute Kidney Injury...

Area of Science:

• Pharmacology
• Nephrology
• Biochemistry

Background:

• Natural flavonoids show promise for treating acute kidney injury (AKI).
• Limited evidence exists on the renal protective effects of Vitisin A.
• Investigating Vitisin A's therapeutic potential in AKI is crucial.

Purpose of the Study:

• To investigate the protective effects of Vitisin A on renal function in lipopolysaccharide (LPS)-induced AKI.
• To elucidate the underlying molecular mechanisms of Vitisin A's action in AKI.
• To evaluate Vitisin A's impact on oxidative stress, inflammation, and apoptosis in AKI.

Main Methods:

• LPS-induced AKI animal models were used to assess renal function via serum creatinine, BUN, and UA.
• Renal tubular injury markers (KIM-1, NGAL) were analyzed using qPCR and Western blot.
• Oxidative stress, inflammation, apoptosis, and signaling pathways (NF-κB, MAPK) were evaluated through protein and cytokine analysis.

Main Results:

• Vitisin A treatment improved renal function, reduced tubular injury markers, and attenuated oxidative stress (NOX4, MDA) and inflammation (TNF-α, IL-6).
• Vitisin A decreased apoptosis and inhibited the activation of NF-κB and MAPK signaling pathways.
• LPS-induced AKI was characterized by impaired renal function, elevated injury markers, oxidative stress, inflammation, and apoptosis.

Conclusions:

• Vitisin A exhibits significant renal protective effects in LPS-induced AKI.
• Vitisin A ameliorates AKI by suppressing inflammation, oxidative stress, apoptosis, and MAPK/NF-κB signaling.
• Vitisin A is a potential therapeutic agent for AKI, warranting further clinical investigation.
