Figure Lengend Snippet: CUR modulates AGE/RAGE signaling and its downstream targets PI3K/Akt and NFκB pathways. (A,B) The levels of plasma (A) and hepatic AGEs (B) were measured by ELISA ( n = 5). (C) The mRNA expression levels of RAGE in the liver were analysed ( n = 3). (D–F) Representative bands and quantitative expression levels of p-PI3K, PI3K, p-Akt, Akt, p-NFκB p65, and NFκB p65 proteins in the liver from Western blot were presented. β-actin was served as an internal reference ( n = 3). For quantitative analysis (D–F) , the band intensity of each target protein was normalized to its corresponding internal control. The normalized values were presented relative to the mean of the NC group, which was set to 1. * p < 0.05, ** p < 0.01 and *** p < 0.001; ns, not significant difference.

Article Snippet: The AGEs levels in the plasma and liver tissues were determined using a mouse-specific ELISA kit (CUSABIO Biotech, Wuhan, China; CAT#CSB-E09414m) according to the manufacturer’s protocol.
