The immunohistochemical analysis was performed using the routine method [12] . The antibodies used included the following: Wnt4 (14371-1-AP; Proteintech, IL, USA), β-catenin (17565-1-AP; Proteintech), renin (14291-1-AP; Proteintech), type 1 angiotensin II receptors (AGTR1) (25343-1-AP; Proteintech), p-nuclear factor erythroid 2-related factor 2 (p-Nrf2) (ab76026; Abcam, Cambridge, MA, USA), p-c-Fos (ab27793; Abcam), connective tissue growth factor (CTGF) (GB11078; Servicebio), and Kelch-like Ech-associated protein-1 (Keap1) (GB11847; Servicebio). The sections were observed under a microscope (Olympus, Tokyo, Japan), and the mean of density value was measured using the Image-Pro Plus analysis software 6.0.

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.
