Cells were seeded into 6-well plates at a density of either 1 × 106 cells per well for analysis on the following day or 0.2 × 106 cells per well if they were to be first subjected to siRNA transfection (for 48 hr). Cells were γ-irradiated, allowed to recover for indicated time periods and then collected and fixed overnight in ice-cold 70% ethanol. Fixed cells were permeabilized with 0.25% Triton-X100 in 1X phosphate-buffered saline (PBS) on ice for 15 min, stained for 2 hr with rabbit anti-phospho-histone H3 (Ser10) Ab (#9701, Cell Signaling) in PBS containing 1% bovine serum albumin (BSA), followed by staining with Fluorescein (FITC)-conjugated AffiniPure goat anti-rabbit IgG (Jackson ImmunoResearch Laboratories) in PBS/1% BSA for 30 min. Phospho-H3 positive cells were quantified by fluorescence-activated cell sorting (FACS) on a Cytomics FC-500 flow cytometer (Beckman-Coulter) with laser excitation at 488 nm. Prior to FACS analysis, propidium iodide (PI) (Sigma, P4170) was added to a final concentration of 10 μg/mL to stain DNA. For each sample, 1.5 × 104 events were scored.

Western Blot Analysis of SOD2 Protein

Check if the same lab product or an alternative is used in the 5 most similar protocols
Single retinas were homogenized and sonicated in lysis buffer and centrifuged. Sample buffer was added to the supernatant just prior to use. Known amounts of protein (10 to 20 μg) or protein ladder were loaded into each well of an SDS-polyacrylamide gel. The Bio-Rad mini-trans blot cell system and mini protean pre-cast gels at 4–20% were used (Hercules, CA). Loading control was GAPDH (rabbit; 1:1000; ab9485, Abcam, Cambridge, MA). The protein was transferred onto nitrocellulose using the Bio-Rad trans blot turbo transfer system (Hercules, CA), probed with anti-SOD2 (rabbit; 1:1000; ab13533; Abcam), probed with secondary antibody (alkaline phosphatase-conjugated AffiniPure Goat Anti-Rabbit IgG; 1:1000; cat #133466; Jackson ImmunoResearch Laboratories) and alkaline phosphatase was used for band detection. Band density was quantified by scanning the blot using an EPSON scanner and Adobe Photoshop to convert to grayscale and invert the image. Each band was selected with the same frame and set measurements were used to obtain the grey mean value for each. (Bernardo-Colon et al., 2018 )

Mouse anti-DRD2 antibody (1:100; Santa Cruz) was used for the identification of the DRD2-containing neurons. FITC-conjugated AffiniPure goat anti-rabbit IgG (1:200, Jackson ImmunoResearch Laboratories, West Grove, USA) and rhodamin-conjugated AffiniPure goat anti-mouse IgG (1:200, Jackson) were used to recognize rabbit anti-LC3B antibody (1:50; Sigma) and mouse anti- beclin-1(BECN1) antibody (1:50; BD), respectively. DAPI (Sigma) was used for nuclear labeling. Terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) solution containing FITC-dUTP (Roche, Basel Schweiz, Switzerland) was used for the detection of DNA fragmentation. Autophagic cell death was identified by the presence of TUNEL (+) BECN1 immunoreactive cells with intact nuclei [23 (link)]. The fields selected for quantification are around the lesion site resided in striatum as shown in panel (C) of S2 Fig, because the cells in the injection site are scarce as shown in the panel (B) of S2 Fig. Five fields per section and night sections per animal were selected for quantification.

For Western Blotting (WB), 6–10 weeks old wild type and ACE2 KO animals were used. Mouse brains were dissected and stored at −80°C. Whole brain lysates were prepared in RIPA buffer supplemented with cOmplete protease inhibitor (Roche Cat # 04693116001). Protein estimation was performed using Pierce BCA protein assay kit (Thermofisher Cat # 23225). Fifteen μg of the sample was loaded in each well of 12% acrylamide gel and SDS–polyacrylamide gel electrophoresis (PAGE) was performed. The proteins were then transferred to Immobilon-P PVDF membranes (Millipore Cat # IPVH00010). Blocking was performed with 5% milk/Tris-buffered saline–Tween 20 for 1 h at room temperature. The membranes were probed with primary anti-ACE2 antibody (Abcam Cat # 15348) and anti-GAPDH (Sigma Cat # G9545) at 1:1000 and 1:5000 dilutions, respectively at 4° C for 16 h. The secondary antibody used was peroxidase-conjugated AffiniPure Goat anti-rabbit IgG (Jackson ImmunoResearch Cat # 111–035-003) at 1:5000 dilution for 1 h at room temperature. Bound antibody was detected using Clarity ECL Western Blotting Substrate (BioRad Cat # 1705061) with the image digitally captured using an ImageQuant LAS 4000 imager.

Prostatic inflammatory infiltrates were graded based on a histopathological classification system (Supplementary Table 1) using H and E staining.11 (link) After being baked, deparaffinized, and rehydrated, prostate tissue sections were stained in hematoxylin (Proteintech Group Inc., Wuhan, China) and eosin-phloxine solution (Servicebio Co., Ltd., Wuhan, China). Then, sections were dehydrated and mounted with neutral glue (Solarbio Co., Ltd., Beijing, China).
The protein expression intensities were identified using IHC staining. After being deparaffinized, rehydrated, antigen retrieved, and blocked, prostate tissue sections were stained with primary antibodies: TLR2 (1:400; NB100-56720, Novus Biologicals Inc., Littleton, CO, USA), TLR10 (1:500; PA5-20054, Thermo Fisher Scientific Co., Ltd., Waltham, MA, USA), high mobility group box 1 (HMGB1; 1:2000; ab18256, Abcam Inc., Cambridge, MA, USA), and biotinylated secondary antibody: AffiniPure Goat anti-Rabbit IgG (Jackson ImmunoResearch Inc., West Grove, PA, USA). Then, sections were dehydrated and mounted with neutral glue. The mean depth of the brown color (three levels) under the microscope (Olympus, Tokyo, Japan) in four random quadrants was regarded as the intensity of relevant protein expression.

After incubation with secondary peroxidase‐conjugated AffiniPure Goat Anti‐rabbit IgG (1:8,000 dilution, Jackson ImmunoResearch), the membranes were exposed to light film (BioMax MR; Kodak, Rochester, NY). The grey value of each protein band was measured, and the TDG protein expression was normalized to GAPDH levels.

Skin samples were lysed with RIPA buffer (BOSTER) and PMSF (BOSTER) to extract protein. The concentration of protein was determined with a BCA protein assay kit (BOSTER). An equivalent amount of protein was loaded onto 10% SDS-PAGE gels (BOSTER), electrophoretically treated and then transferred to PVDF membranes (Millipore). The membranes were incubated with 5% nonfat milk in TBS-T for 2 h at room temperature, and then incubated with primary antibodies at 4 °C overnight. The membranes were incubated with secondary antibodies for 2 h at room temperature, and the protein bands were visualized using ECL reagents. Finally, the bands were photographed using gel image analysis system (Tanon Science & Technology Co., Shanghai, China) and the intensity of the bands was quantified in Gel-Pro analyzer software (Media Cybernetics). The details of the primary and secondary antibodies are as follows: anti-iNOS (1:1000, Thermo Fisher Scientific), anti-Arg-1 (1:500, BOSTER), and horseradish peroxidase-conjugated AffiniPure goat anti-rabbit IgG (1:2000, Jackson ImmunoResearch).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
