Immunostaining was performed on 3 µm sections after deparaffinization. Microwave or high pressure antigen retrieval was performed in citrate buffer pH 6.0 for 10 min prior to peroxidase quenching with 3% H2O2 in phosphate-buffered saline (PBS) for 10 min. The sections were then washed in water and preblocked with normal goat or rabbit serum for 10 min. Then, slides were incubated, respectively, with anti-Wnt5a (Abcam, USA), anti-JNK1 (Santa Cruz Biotechnology, USA), anti-NF-κB p65 (Santa Cruz Biotechnology, USA), and anti-COX-2 (Santa Cruz Biotechnology, USA) (final concentrations 1∶100, 1∶100, 1∶200, 1∶320, respectively) for over-night at 4°C. The sections were then incubated with biotinylated secondary antibodies (1∶400) for 20 min. Following a washing step with PBS, the avidin–biotin complex was applied. Finally, the sections were rinsed in PBS, developed with diaminoben-zidine tetrahydrochloride substrate for 3 min and counterstained with hematoxylin. Five fields with a final magnification of ×400 were randomly selected for each rat liver, and the Integral Optical Density(IOD) were analyzed by Image Pro Plus 6.0 software.

Proteins were extracted from the OS tissues or cultured OS cells by RIPA lysis buffer (Abcam) with protease inhibitor supplement. The concentration of protein in each sample was quantified by BCA assay with a standard assay kit (Thermo Fisher Scientific). Equal amount of protein was loaded for SDS‐PAGE. Proteins in the gels were then transferred to Nitrocellulose membranes (Millipore). Following that, 5% skimmed milk was used as blocking buffer to block the membranes for 30 min at room temperature and then primary antibodies were added for incubation at 4°C overnight. The membranes were washed with TBST three times and then incubated with specific species secondary antibodies (KPL) at room temperature for 2 hours. The membranes were washed again before visualization using an ECL kit. The primary antibodies used for the study were as follows: anti–GLUT1 (1:1000; Santa Cruz); anti–HK2 (1:500; Cell Signaling); (1:800; Cell Signaling); anti–LDHA (1:800; Cell Signaling); anti–Wnt5a (1:800; Abcam); anti–Ror2 (1:800; Abcam); and anti–β‐actin (1:2000; Abcam).

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.
