This study aims to explore the protective impact of azilsartan (AZIL), an antihypertensive drug, in addition to adipose tissue-derived mesenchymal stem cells (AD-MSCs) on CISP-induced hepatotoxicity. After characterization and labeling of AD-MSCs by PKH26 dye, 54 Wistar male albino rats were randomly divided into nine groups: I (CONT), II (AZIL.H), III (CISP), IV (CISP + AZIL.L), V (CISP + AZIL.H), VI (CISP + AD-MSCs), VII (CISP + AZIL.L + AD-MSCs), VIII (CISP + AZIL.H + AD-MSCs), and IX (CISP + VITA C). Serum alanine aminotransferase (ALT), alanine aminotransferase (AST), and albumin levels were determined. Assessment of reactive oxygen species, malondialdehyde, and glutathione contents, and superoxide dismutase activity and histopathological evaluations were done on hepatic tissue. Quantitative real-time PCR was utilized to estimate the expression of <i>TNF-α</i> and <i>IL-6</i> genes. Cell homing of labeled AD-MSCs to the liver tissues was investigated. Hepatic expression of JNK1/2, ERK1/2, p38, Bax, Bcl-2, and cleaved caspase-3 proteins was investigated by western blot analysis. CISP elevated serum ALT and AST activities, reduced albumin level, and remarkably changed the hepatic architecture. It increased the expression <i>TNF-α</i> and <i>IL-6</i> genes, raised the expression of JNK1/2, ERK1/2, p38, Bax, and cleaved caspase-3 proteins, and diminished the Bcl-2 protein. By contrast, treatment of animals with either AZIL or AD-MSCs dramatically reduced the effects of CISP injection. Moreover, treatment with combination therapy (AZIL.L or H + AD-MSCs) considerably mitigated all previously mentioned alterations superior to AZIL or AD-MSCs alone, which might be attributed to the AZIL-enhanced homing ability of AD-MSCs into the injured liver tissue. In conclusion, the present findings demonstrated that AZIL improves the hepatoprotective potential of AD-MSCs against CISP-induced hepatotoxicity by modulating oxidative stress, mitogen-activated protein kinase, and apoptotic pathways.</p>","PeriodicalId":21962,"journal":{"name":"Stem Cells International","volume":"2023 ","pages":"6767735"},"PeriodicalIF":4.3,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10615573/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71427000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TG2 is highly expressed in mesenchymal stem cells (MSCs) compared with differentiated cells, suggesting a role of TG2 specific for MSC characteristics. In this study, we report a new function of TG2 in the regulation of MSC redox homeostasis. During <i>in vitro</i> MSC expansion, TG2 is required for cell proliferation and self-renewal by preventing premature senescence but has no effect on the expression of surface antigens and oxidative stress-induced cell death. Moreover, induction of differentiation upregulates TG2 that promotes osteoblastic differentiation. Molecular analyses revealed that TG2 mediates tert-butylhydroquinone, but not sulforaphane, -induced nuclear factor erythroid 2-related factor 2 (NRF2) activation in a transamidase activity-independent manner. Differences in the mechanism of action between two NRF2 activators suggest that PDI activity of TG2 may be implicated in the stabilization of NRF2. The role of TG2 in the regulation of antioxidant response was further supported by transcriptomic analysis of MSC.

However, hormone and immunosuppressive therapy can cause serious side effects, such as Cushing syndrome and bone marrow suppression. Previous studies reported on the applicability and safety of mesenchymal stem cells (MSCs) to ameliorate liver inflammation and fibrosis. However, the characteristics of MSCs sources directly contribute to the different conclusions on the mechanisms underlying MSC-mediated immunoregulation. Bone marrow-derived MSCs can exert an immunosuppression effect to ameliorate the S100-induced AIH model by inhibiting several proinflammatory cytokines and upregulating of PD-L1 in liver tissue. It is not clear whether human umbilical cord-derived MSCs (hUC-MSCs) could directly inhibit liver inflammation and ultimately alleviate the dysfunction of hepatocytes in the AIH model. First, hUC-MSCs were extracted from umbilical cord tissue, and the basic biological properties and multilineage differentiation potential were examined. Second, 1 × 10⁶ hUC-MSCs were administered intravenously to AIH mice. At the peak of the disease, serum levels of alanine aminotransferase and aspartate aminotransferase and pathologic damage to liver tissue were measured to evaluate liver function and degree of inflammation. We also observed that the infiltration of CD4⁺ T cells in the liver was significantly reduced. Furthermore, the frequency of the splenic IFN<i>γ</i>- and IL-17A- producing CD4⁺ T cells were also significantly decreased, while we only observed an increasing trend in Treg cells in liver tissue. Third, an RNA sequencing analysis of liver tissue was performed, which showed that in the UC-MSC-treated group, the transcriptional profiles of inflammation-related signaling pathways were significantly negatively regulated compared to those of phosphate-buffered saline-treated mice.

In this work, we discovered that VCAM-1 was significantly downregulated in the bone marrow mesenchymal stem cells (BMSCs) derived from patients with TI-ONFH.

Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that upregulated DEGs were engaged in the Apelin signaling pathway.

Treatment with Apelin-13 activated the Apelin signaling pathway and suppressed the expression of cellular communication network factor 2 in BMSCs. Furthermore, Apelin-13 also inhibits the migration and angiogenesis of VCAM-1-BMSCs.
