Inhibition of elevated FPR2 is protective against kidney injury. The left renal pedicle of the rat was clamped for 45 min to induce IRI. The right kidney was removed before releasing the clamps. WRW4 (10 mg/kg; single dose) was administered intravenously 30 min before surgery. Serum or kidney tissues were collected 24 h after surgery. Kidney tissues were sectioned for histological examination and TUNEL staining. Scale bar, 100 μm. TUNEL staining results showed a decrease in the number of apoptotic renal tubular cells in the WRW4 pretreatment group compared with the surgical group.

Positive expression of p65 in liver tissue was observed by immunofluorescence staining under a laser scanning confocal microscope. The p65 cells were marked in red, and the nucleus was stained with 4′,6-diamidino-2-phenylindole (DAPI) in blue. Scale bars = 50 μm. The results showed that the expression level of p65 within the hepatocytes' nuclei was elevated in the CRS group rats; in the CRS + CGA group, the p65 expression level was reduced; furthermore, this effect of CGA was reversed by WRW4 (0.1 mg/kg; i.p.).

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Calcium Spark Assay
Calcium sparks are localized, transient increases in intracellular calcium concentration ([Ca2+]i) that occur in cardiac myocytes and represent elementary events underlying excitation-contraction coupling. These events are generated by the coordinated opening of clusters of ryanodine receptors (RyRs) on the sarcoplasmic reticulum membrane, leading to a brief release of Ca2+ into the cytosol. The detection and analysis of calcium sparks provide insights into the mechanisms of calcium handling and signaling in cardiac cells. Imaging techniques using fluorescent calcium indicators such as Fluo-3 are employed to visualize these subcellular calcium transients with high spatial and temporal resolution. The protocol is based on established methodologies described in primary literature for both experimental measurement and automated analysis of calcium sparks.

Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.

Amyloid: Congo Red Amyloid Staining
Congo red amyloid staining is a histochemical method used to detect extracellular amyloid deposits in tissue sections based on the affinity of Congo red dye for β-pleated sheet-rich protein aggregates. When bound to amyloid, Congo red produces characteristic apple-green birefringence under polarized light microscopy, which is widely regarded as a diagnostic feature of amyloid deposition in histopathology. The diagnostic principle relies on the combination of dye binding (congophilia) and optical anisotropy under polarized illumination, which distinguishes amyloid from most non-amyloid eosinophilic extracellular deposits in routine histological evaluation. Amyloid identification by Congo red staining remains a cornerstone in diagnostic pathology despite the availability of adjunct methods such as immunohistochemistry and mass spectrometry, particularly because of its ability to localize deposits directly within tissue architecture. The specificity of Congo red-positive deposits is incre
