Ability to Suppress TGF- β-Activated Myofibroblast Differentiation Distinguishes the Anti-pulmonary Fibrosis Efficacy of Two Danshen-Containing Chinese Herbal Medicine Prescriptions
Conclusion: This study suggests that a clinically efficacious cardiovascular Chinese herbal medicine (DLP) can be successfully repurposed to treat a lung disease in pulmonary fibrosis guided by TCM theory. Our comparative study between DLP and DHP demonstrated a critical requirement of suppressing both pro-inflammatory and pro-fibrotic pathways for the treatment of pulmonary fibrosis, supporting that a multi-component prescription capable of “removing both phlegm and blood stasis” will better achieve co-protection of heart and lung in PHD. Introduction Idiopathic pulmonary fibrosis (IPF) is a chronic ...

Increasing Upstream Chromatin Long –Range Interactions May Favor Induction of Circular RNAs in LysoPC-Activated Human Aortic Endothelial Cells
We examined the sponging potential of all significantly changed circRNAs using the CircInteractome database (Montefiori et al., 2018), recording two miRNAs with four or more predicted binding sites in a single circRNA transcript, a threshold above which meaningful sponging activity is likely to occur Memczak et al. (2013). Another four significantly changed circRNAs are experimentally shown to sponge miRNAs (Dudekula et al., 2016; Chen et al., 2017; Yan et al., 2017; Wang et al., 2018), for six total circRNAs with miRNA sponging activity including miR125, miR143, miR1272, miR153, miR515-5p, and miR196a-5p (Table 4). In Fig...

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...

Immune-Modulation by the Human Respiratory Syncytial Virus: Focus on Dendritic Cells
This study is complemented by another report that found that hRSV infection induces significant expression of three miRNAs, namely hsa-miR-4448, hsa-miR-30a-5p, and hsa-miR-4634 in human DCs (104). Interestingly, this latter study also performed comparative analyses of miRNA profiles between DCs infected with hRSV and a related virus, namely the human metapneumovirus, and found that both viruses induced the expression of elevated levels of hsa-miR-4634. Elucidating the contribution of these miRNAs in DCs in response to hRSV remains to be determined. Dendritic Cell Phenotype and Migration Upon hRSV Infection in vivo Altho...

LIM kinase 1 acts as a profibrotic mediator in permanent atrial fibrillation patients with valvular heart disease.
Abstract Atrial fibrillation (AF) is the most frequently diagnosed cardiac arrhythmia worldwide. Patients with permanent atrial fibrillation are at an increased risk of developing valvular heart disease. Atrial fibrosis occurs in this pathophysiological setting. LIM kinase 1 (LIMK1) is a serine/threonine kinase that regulates microtubule stability and actin polymerization in fibroblasts. LIMK1 has been implicated in the pathogenesis of atrial fibrillation. Clinical data and biopsies of the right atrial appendage were collected from 50 patients with valvular heart disease who underwent heart valve replacement surge...

Mechanisms of Niemann Pick type C1 Like 1 Protein Degradation in Intestinal Epithelial Cells.
In conclusion, our results showed that basal level of intestinal cholesterol transporter NPC1L1 protein is modulated by both ubiquitin-proteasome and lysosome-dependent degradation as well as by ERK1/2-dependent pathway. The modulation of these pathways may provide novel clues for therapeutic intervention to inhibit cholesterol absorption and lower plasma cholesterol.

Irisin attenuates angiotensin II-induced cardiac fibrosis via Nrf2 mediated inhibition of ROS/ TGFβ1/Smad2/3 signaling axis
In this study, we found that angiotensin II-induced cardiac dysfunction and fibrotic responses were dampened by irisin treatment in mice. Mechanistically, angiotensin II induced robust ROS generation, which in turn triggered activation of pro-fibrotic TGFβ1-Smad2/3 signaling and subsequent collagen synthesis and fibroblast-myofibroblast transformation in cardiac fibroblasts. In contrast, Irisin treatment suppressed angiotensin II-induced ROS generation, TGFβ1 activation, collagen synthesis and fibroblast-myofibroblast transformation, the effects of which was accompanied by Nrf2 activation and also abolished by a Nrf2 tar...

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 ...
