Tackling of Renal Carcinogenesis in Wistar Rats by Silybum marianum Total Extract, Silymarin, and Silibinin via Modulation of Oxidative Stress, Apoptosis, Nrf2, PPARγ, NF-κB, and PI3K/Akt Signaling Pathways

Figure 11

Effect of STE, Sm, and Sb on PI3K/Akt signaling pathway in kidney tissues of rats given DEN/AAF/CCl4. Western blot assay was used to measure the expressions of p/t-PI3K (b) and p/t-Akt (c) proteins in kidney tissues of the experimental groups. Representative immunoblots for quantification of p/t-PI3K and p/t-Akt proteins were depicted in (a). Data are presented as with results from 3 independent biological repeats. , , and were significant as compared with normal control rats, and #, ##, and ### were significant as compared with the DEN/AAF/CCl4-administered group. STE+DEN/AAF/CCl4, Sm+DEN/AAF/CCl4, and Sb+DEN/AAF/CCl4: groups orally treated with STE, Sm, and Sb, respectively, from the 1st week of DEN injection; DEN/AAF/CCl4+STE, DEN/AAF/CCl4+Sm, and DEN/AAF/CCl4+Sb: groups orally treated with STE, Sm, and Sb, respectively, from the 16th week of DEN injection.
