Protein Expression Analysis by Western Blot

Cells were lysed by radioimmunoprecipitation assay (RIPA) buffer (Pierce) on ice to obtain total protein. Samples were centrifuged at 14,000g for 15 min at 4 °C and then heated at 95 °C for 5 min in 1× SDS loading buffer. We separated the protein by using 8% or 10% SDS–polyacrylamide gels and transferred it to PVDF membranes by a wet transfer apparatus (Bio-Rad). The membranes were blotted with 5% milk or bovine serum albumin (BSA) for 1 h and then incubated with primary antibodies at 4 °C overnight (70 (link)). The following antibodies were used: rabbit anti-ALKBH1 (1:2000, ab128895, Abcam), rabbit anti-HIF-1α (1:1000, ER1802-41, Huabio, Boston), rabbit anti-GYS1 (1:1000, ET1611-59, Huabio), rabbit anti-VEGF (1:2000, ET1604-28, Huabio), rabbit anti-GLUT1 (1:2000, ET1601-10, Huabio), rabbit anti-LDHA (1:2000, ET1608-57, Huabio), rabbit anti-CEBPA (1:2000, ET1612-46, Huabio), rabbit anti-FABP4 (1:2000, ET1703-98, Huabio), mouse anti-α-tubulin (1:2,000, sc-32293; Santa Cruz Biotechnology). The complexes were incubated in horseradish peroxidase conjugated anti-rabbit or anti-mouse IgG secondary antibodies (Cell signaling Technology) and visualized with Immobilon reagents (Millipore).

Histological Analysis of Kidney Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Commercial kits (Sigma-Aldrich, United States) were used for Masson or HE staining of kidney tissue according to the manufacturer’s protocol. Masson staining and immunostaining intensity were scored by photograph, randomly selected under 200 magnified visual field with a light microscope. According to the degrees of tubule degeneration and necrosis, tubule atrophy, inflammatory cell infiltration, and fibrosis, 0, 1, 2, and 3 were scored. The collagen-blue area representing the lesion area after Masson staining was calculated. The staining area was measured by the average optical density of the immunostaining intensity score. The ratios of FABP4-positive area to total area in kidney in glomeruli at a magnification of ×400 and in the cortical tubulointerstitium except glomeruli and vascular lumen at a magnification of ×200 were calculated as FABP4 positive in glomerular and FABP4 positive in interstitial, respectively.
Immunohistochemical staining was performed on 4-μm kidney sections as previously described. After antigen retrieval, sections were incubated with the primary antibody against α-SMA (ab5694; Abcam, United States), Col-1 (BA0325; Bosterbio, United States), FN (BA1772; Bosterbio), FABP4 (ET1703-98, HuaBio, China), F4/80 (RT1212; HuaBio), or CD68 (ab955; Abcam), respectively, and then detected by the En Vision/HRP Kit (Dako, Carpinteria, CA, United States).

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.
