An Effective Mouse Model of Unilateral Renal Ischemia-Reperfusion Injury

Area of Science:

• Nephrology
• Surgical Pathology
• Experimental Medicine

Background:

• Ischemia-reperfusion injury (IRI) is a primary cause of acute renal failure and delayed graft function.
• Animal models are crucial for studying in vivo IRI mechanisms.
• A reliable and reproducible model is needed to understand IRI's complexities.

Purpose of the Study:

• To describe an effective mouse model for unilateral renal IRI.
• To provide a sequential overview of physiological and histopathological changes post-IRI.
• To offer practical data for experimental planning.

Main Methods:

• Induction of ischemia by occluding the right renal pedicle for 30 minutes.
• Evaluation of physiological and histopathological changes at seven reperfusion time points (4h to 7 days).
• Documentation of surgical time, anesthetic consumption, and body weight changes.

Main Results:

• The described mouse model yields highly reproducible data for renal IRI.
• Sequential data illustrate expected changes across various reperfusion durations.
• Key experimental planning metrics are provided.

Conclusions:

• This validated renal IRI mouse model facilitates reliable research.
• The study assists researchers in choosing appropriate reperfusion times for their specific goals.
• Implementation of this model can advance the understanding and treatment of IRI.
