Analysis. Immunohistochemical analysis was performed as previously described [25]. Briefly, paraffin-embedded renal tissue sections have been dewaxed with xylene, dehydrated using a gradient series of alcohol, incubated with H2O2, and sealed with goat serum. Subsequently, sections were incubated with key and secondary antibodies and labeled with horseradish enzyme. DAB was applied for colour development. Ultimately, all sections have been observed and photographed below a DP73 microscope (Olympus, Tokyo, Japan). two.8. TUNEL Assay. Paraffin-embedded renal tissue sections were pretreated in accordance with the TUNEL apoptosis detection kit (Roche, Basel, Switzerland) manufacturer’s instructions and after that wetted for 60 min with 50 L of TdT enzyme reaction solution at 37 . Soon after 30 min reaction with antifluorescent antibody inside the dark, sections were incubated with DAB (5000 L) functioning option for 50 min at area temperature. All sections were captured applying a fluorescence inverted microscope (TE2000, Nikon). Apoptosis rates were calculated in six noncontinuous fields of every section by ImageJ software program. 2.9. Determination of Protein Expression. Protein expression levels of Bax, Bcl-2, and cleaved caspase three (Wanlei Biotechnology, Shenyang, China) in renal tissues have been determined by western blot evaluation. Briefly, frozen kidney tissues had been 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 PIM2 Inhibitor Accession volumes of protein were separated by sodium dodecyl sulfatepolyacrylamide gel electrophoresis and transferred to polyvinylidene fluoride membranes, which had been incubated with main antibodies of Bax (1 : 1000), Bcl-2 (1 : 500), andTable 1: The catalog numbers of all kits.

Immediately after washing, membranes had been incubated with goat anti-rabbit secondary antibody (ZSGB-BIO, Beijing, China) at 37 for 2 h. All protein bands were captured with Amersham Imager 600 software (GE, Boston, MA, USA) and quantified with ImageJ. 2.10. 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), mGluR5 Modulator Accession calcium-independent phospholipase A2 (iPLA2), secreted phospholipase A2 (sPLA2), and cytosolic phospholipase A2 (cPLA2) in renal tissues have been determined with real-time PCR evaluation, as previously described [26]. All primers (Table 2) have been synthesized by Shanghai Bioengineering Co. (Shanghai, China). GAPDH mRNA expression levels have been used as a reference to quantify relative expression levels of genes. Gene levels were quantified according to the 2-Ct process. 2.11. Statistical Analysis. All information represent the mean SEM and were analyzed applying IBM SPSS Statistics 23 software program (Armonk, NY, USA). Statistical analysis was conducted by way of one-way ANOVA, followed by Tukey’s post hoc test. Mea.
