Animals were anesthetized with sodium pentobarbital (60 mg/kg body weight) and
perfused with phosphate-buffered saline (PBS) followed by fresh 4%
paraformaldehyde. L3-5 SDHs were collected from rats, fixed in 4%
paraformaldehyde overnight and cryopreserved in 30% sucrose at 4°C overnight.
Tissues were mounted and sectioned on a cryostat at a thickness of 12 µm. Tissue
sections were permeabilized with 0.3% Triton X-100 (Amresco, Solon, USA) in PBS
for 15 min, followed by antigen retrieval with Quick Antigen Retrieval Solution
for Frozen Sections (Beyotime, Jiangsu, China). Then, the sections were
incubated with 3% BSA for 1 h at room temperature and then with primary
antibodies overnight at 4°C. The following primary antibodies were used:
anti-glial fibrillary acidic protein (GFAP; Abcam, Cambridge, UK), anti-ionized
calcium binding adaptor molecule 1 (IBA1; Abcam, Cambridge, UK), anti-NeuN
(Abcam, Cambridge, UK), anti-p-NF-κB (Abcam, Cambridge, UK) and anti-RAGE
(Abcam, Cambridge, UK). The tissue sections were washed three times and
incubated with the appropriate secondary antibodies for 1 h at room temperature.
After the slides were washed in PBS, coverslips were applied with mounting
medium with DAPI (ZSGB-BIO, Beijing, China). The sections were examined on an

Extraction of the total protein was performed from the frozen tissues with the aid of lysis buffer (Solarbio, China). BCA assay was used to measure the protein concentration (Sangon, China) according to the manufacturers’ protocol. Separation of total protein samples was executed using 10% SDS polyacrylamide gel electrophoresis, and then transferred onto the PVDF (Millipore, USA). Later, the transmembrane was subjected to blocking using a blocking buffer made of ‘5% nonfat milk, 0.1% Tween 20’. Later, the membranes were probed with anti-HMGB1 (1:1000 dilution, Abcam, USA), anti-RAGE (1:2000 dilution, Abcam, USA) primary antibodies and incubated overnight at 4 °C, respectively. Next, the membranes were washed 3 times using PBS. Then, the membranes were subjected to incubation for two hours at room temperature with secondary antibodies (1:2000 dilution, Odyssey CIX, USA). The blots were observed using Infrared Laser Scanning Imaging System (Odyssey CIX, USA).

Primary human arterial endothelial cells and PASMC were lysed in RIPA buffer (Sigma-Aldrich) and 10 μg of protein were run on a 10% SDS polyacrylamide gel, followed by electrotransfer to an Amersham Hybond P 0.45 PVDF Blotting Membrane (GE Healthcare, Wien, Austria). After blocking with 5% non-fat dry milk in TBS-T buffer (Tris-buffered saline with 0.1% Tween-20), the membrane was incubated overnight at 4°C with one of the following antibodies: anti-p38, anti–phospho-p38 (T180/Y182), anti-c-Jun; anti-phospho c-Jun (S73), anti-phospho Erk1/2 (T202/Y204), anti-Erk1/2, anti-phospho c-Fos (S32) all from Cell Signaling and anti-c-Fos (Novus Biologicals, Cambridge, UK) were used at dilution of 1:1000; and anti-TLR4 (Abcam), anti-RAGE (1:500; Abcam) and rabbit anti–alpha-tubulin (1:5000; Cell Signaling, Boston, MA, USA). After washing, the membranes were incubated with horseradish-peroxidase–labelled secondary antibodies (1:5000, anti-rabbit-HRP, Pierce, Thermo Fisher Scientific, Waltham, MA, USA) and proteins detected with Amersham ECL Prime Western Blotting Detection System (GE Healthcare). Antibodies were removed by incubating the membrane for 15 min. with stripping buffer (RestoreTM PLUS Western Blot Stripping Buffer; Thermo Scientific). Densitometric analysis was performed with ImageJ (National Institutes of Health, USA).

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.
