Evaluation. Immunohistochemical evaluation was performed as previously described [25]. Briefly, paraffin-embedded renal tissue sections have been dewaxed with xylene, NUAK1 Inhibitor Purity & Documentation dehydrated having a gradient series of alcohol, incubated with H2O2, and sealed with goat serum. Subsequently, sections had been incubated with key and secondary antibodies and labeled with horseradish enzyme. DAB was used for color improvement. Finally, all sections have been observed and photographed under a DP73 microscope (Olympus, Tokyo, Japan). two.8. TUNEL Assay. Paraffin-embedded renal tissue sections had been pretreated as outlined by the TUNEL apoptosis detection kit (Roche, Basel, Switzerland) manufacturer’s guidelines and then wetted for 60 min with 50 L of TdT enzyme reaction resolution at 37 . Following 30 min reaction with antifluorescent antibody inside the dark, sections were incubated with DAB (5000 L) working solution for 50 min at room temperature. All sections had been captured applying a fluorescence inverted microscope (TE2000, Nikon). Apoptosis rates were calculated in six noncontinuous fields of every section by ImageJ application. two.9. Determination of Protein Expression. Protein expression levels of Bax, Bcl-2, and cleaved caspase 3 (Wanlei Biotechnology, Shenyang, China) in renal tissues were determined by western blot evaluation. Briefly, frozen kidney tissues were lysed with radioimmunoprecipitation assay lysis buffer mixed with phenylmethylsulfonyl fluoride (Beyotime Biotechnology, Shanghai, China). Right after detection of total protein concentrations having a bicinchoninic acid assay kit (Beyotime Biotechnology), samples with equal volumes of protein were separated by sodium dodecyl sulfatepolyacrylamide gel electrophoresis and transferred to polyvinylidene fluoride membranes, which have been incubated with key antibodies of Bax (1 : 1000), Bcl-2 (1 : 500), andTable 1: The catalog numbers of all kits.

Immediately after washing, membranes have been incubated with goat anti-rabbit secondary antibody (ZSGB-BIO, Beijing, China) at 37 for 2 h. All protein bands have been captured with Amersham Imager 600 computer software (GE, Boston, MA, USA) and quantified with ImageJ. 2.ten. Determination of Gene Level. Gene expression levels of cytochrome P450 (CYP) 4A1, CYP4A2, CYP4A3, CYP4A8, cyclooxygenase 1 (COX1), cyclooxygenase two (COX2), leukotriene B4 receptor 1 (BLT1), calcium-independent phospholipase A2 (iPLA2), secreted phospholipase A2 (sPLA2), and cytosolic phospholipase A2 (cPLA2) in renal tissues have been determined with real-time PCR analysis, as previously described [26]. All primers (Table two) had been synthesized by Shanghai Bioengineering Co. (Shanghai, China). GAPDH mRNA expression levels were made use of as a reference to quantify relative expression levels of genes. Gene levels have been quantified according to the 2-Ct process. two.11. Statistical Analysis. All data represent the imply SEM and have been analyzed employing IBM SPSS Statistics 23 computer software (Armonk, NY, USA). Statistical analysis was performed through one-way ANOVA, followed by Tukey’s post hoc test. Mea.
