FGF21 as Modulator of Metabolism in Health and Disease
In conclusion, FGF21 belongs to a promising class of cytokines that are induced in response to stress and that can be used as a drug, drug target, or through a biomarker, depending on the physio-pathological context. All these findings will become clear when FGF21 will be used as a therapeutic molecule, exploiting the beneficial effects of FGF21 for treating metabolic disease or when it will be blocked to ameliorate disease progression and the onset of disease. Author Contributions CT and MS wrote the manuscript. VR contributed to the discussion. Funding This work was supported from the AFM-Telethon (19524), Italian Mi...

Mineralocorticoid receptor deficiency improves the therapeutic effects of mesenchymal stem cells for myocardial infarction via enhanced cell survival.
Abstract The poor survival of stem cells seriously limits their therapeutic efficacy for myocardial infarction (MI). Mineralocorticoid receptor (MR) activation plays an important role in the pathogenesis of multiple cardiovascular diseases. Here, we examined whether MR silencing in bone marrow derived mesenchymal stem cells (MSCs) could improve MSCs' survival and enhance their cardioprotective effects in MI. MSCs from male Sprague-Dawley rats were transfected with adenoviral small interfering RNA to silence MR (siRNA-MR). MR silencing decreased hypoxia-induced MSCs' apoptosis, as demonstrated by Annexin V/7-AAD st...

Sphingosine 1-phosphate promotes mesenchymal stem cell-mediated cardioprotection against myocardial infarction via ERK1/2-MMP-9 and Akt signaling axis
Publication date: Available online 24 October 2018Source: Life SciencesAuthor(s): Ruirui Chen, Xiqiang Cai, Jing Liu, Baobao Bai, Xue LiAbstractAimsThe sphingolipid metabolite sphingosine 1‑phosphate (S1P) has emerged as a potential cardioprotective molecule against ischemic heart disease. Moreover, S1P triggers mobilization and homing of bone marrow-derived stem/progenitor cells into the damaged heart. However, it remains elusive whether S1P promotes mesenchymal stem cells (MSCs)-mediated cardioprotection against ischemic heart diseases.Main methodsAdipose tissue-derived MSCs (AT-MSCs) were obtained from GFP transgenic ...

The roles of nanocarriers on pigment epithelium-derived factor in the differentiation of human cardiac stem cells
In this study, we utilized organically modified silica (ORMOSIL) nanoparticles to deliver small interfering RNA (siRNA) against pigment epithelium-derived factor (PEDF) and induce the differentiation of human cardiac stem cells (CSCs). We found that the down-regulation of PEDF can inhibit the proliferation of human CSCs and induce cell differentiation. To further study the mechanism, we have tested the Notch signalling pathway genes, Hes1 and Hes5, and found that their expressions were inhibited by the PEDF down-regulation. Furthermore, with the restoration of PEDF, both the proliferation of human CSCs and expressions of H...

Sry-type HMG box 18 contributes to the differentiation of bone marrow-derived mesenchymal stem cells to endothelial cells.
CONCLUSION: Here we demonstrate that VEGF-165 mediates MSC differentiation into ECs via VEGFR-2-dependent induction of Sox18, which ultimately coordinates the transcriptional upregulation of specific markers of the EC phenotype. PMID: 25913202 [PubMed - as supplied by publisher]
