MK-2206 Alleviates Renal Fibrosis by Suppressing the Akt/mTOR Signaling Pathway In Vivo and In Vitro.
    Cells, 2022, 11-05, Volume: 11, Issue:21

    Renal fibrosis is a common pathological feature of various kidney diseases, leading to irreversible renal failure and end-stage renal disease. However, there are still no effective treatments to reverse renal fibrosis. This study aimed to explore the potential mechanism of a targeted drug for fibrosis. Here, unilateral ureteral obstruction (UUO)-treated mice and a TGF-β1-treated human renal tubular epithelial cell line (HK-2 cells) were used as models of renal fibrosis. Based on the changes of mRNA in UUO kidneys detected by transcriptome sequencing, MK-2206, an Akt inhibitor, was predicted as a potential drug to alleviate renal fibrosis through bioinformatics. We dissolved UUO mice with MK-2206 by gastric gavage and cultured TGF-β-induced HK-2 cells with MK-2206. Histopathological examinations were performed after MK-2206 intervention, and the degree of renal fibrosis, as well as the expression of Akt/mTOR pathway-related proteins, were evaluated by immunohistochemical staining, immunofluorescence staining, and Western blot. The results showed that MK-2206 significantly improved the pathological structure of the kidney. Furthermore, MK-2206 intervention effectively inhibited UUO- and TGF-β1-induced epithelial-mesenchymal transition, fibroblast activation, and extracellular matrix deposition. Mechanistically, MK-2206 treatment attenuated the activation of the Akt/mTOR signaling pathway. Taken together, our study revealed for the first time that MK-2206 is a promising drug for the improvement of renal fibrosis.

NR4A1 is Involved in Fibrogenesis in Ovarian Endometriosis.
    Cellular physiology and biochemistry : international journal of experimental cellular physiology, biochemistry, and pharmacology, 2018, Volume: 46, Issue:3

    Excess fibrosis may lead to chronic pain, scarring, and infertility as endometriosis develops and progresses. The pathogenesis of endometriosis has been linked to transforming growth factor-β (TGF-β), the most potent promoter of fibrosis.. Levels of NR4A1 and P-NR4A1 protein in human endometrial and endometriotic tissue were assessed by western blotting and immunohistochemistry. The expression levels of fibrotic markers in stromal cells were evaluated by real-time PCR. The degree of fibrosis in mouse endometriotic lesions was detected by Masson trichrome and Sirius red staining.. The level of phosphorylated-NR4A1 was higher in ovarian endometriotic tissue than in normal endometrium, and long-term TGF-β1 stimulation phosphorylated NR4A1 in an AKT-dependent manner and then promoted the expression of fibrotic markers. Furthermore, inhibition of NR4A1 in stromal cells increased the TGF-β1-dependent elevated expression of fibrotic markers, and loss of NR4A1 stimulated fibrogenesis in mice with endometriosis. Additionally, Cytosporone B (Csn-B), an NR4A1 agonist, effectively decreased the TGF-β1-dependent elevated expression of fibrotic markers in vitro and significantly inhibited fibrogenesis in vivo.. NR4A1 can regulate fibrosis in endometriosis and may serve as a new target for the treatment of endometriosis.
