Myocardial infarction (MI) is one of the leading causes of death worldwide and Mesenchymal Stem Cells (MSCs) transplantation has been considered a promising therapy. Recently, it was reported that the therapeutic effectiveness of MSCs is dependent on the age of the donor, yet the underlying mechanism has not been thoroughly investigated. This study was(More)
Recent studies have demonstrated that bone marrow-derived fibroblasts contribute significantly to the pathogenesis of renal fibrosis. However, the signaling mechanisms underlying the activation of bone marrow-derived fibroblasts in the kidney are incompletely understood. As TGF-β1/Smad3 signaling has been shown to have an important role in the pathogenesis(More)
Recent studies have shown that bone marrow-derived fibroblasts contribute significantly to the pathogenesis of renal fibrosis. However, the molecular mechanisms underlying the recruitment of bone marrow-derived fibroblasts into the kidney are incompletely understood. Bone marrow-derived fibroblasts express the chemokine receptor--CCR2. In this study, we(More)
Recent evidence indicates that inflammation plays a critical role in the initiation and progression of hypertensive kidney disease. However, the signaling mechanisms underlying the induction of inflammation are poorly understood. We found that chemokine (C-X-C motif) ligand 16 (CXCL16) was induced in renal tubular epithelial cells in response to angiotensin(More)
Tubulointerstitial fibrosis (TIF) is caused by the progressive loss of renal tubular cells and the consequent replacement of the extracellular matrix. The progressive depletion of renal tubular cells results from apoptosis and necroptosis; however, the relative significance of each of these cell death mechanisms at different stages during the progression of(More)
BACKGROUND Increasing evidences indicated that adipose-derived mesenchymal stem cells (ADMSCs) can stay survive, then gradually proliferate and differentiate into myocardial cells after transplanted into damaged areas and improve function of heart. METHODS In this article, ADMSCs were isolated from adipose tissue of Wistar rats and cultured. When treated(More)
OBJECTIVE Recent studies have shown that angiotensin II (Ang II) plays a critical role in the pathogenesis and progression of hypertensive kidney disease. However, the signaling mechanisms are poorly understood. In this study, we investigated the role of CXCR6 in Ang II-induced renal injury and fibrosis. APPROACH AND RESULTS Wild-type and CXCR6-green(More)
Bone marrow-derived fibroblasts in circulation are of hematopoietic origin, and they proliferate, differentiate into myofibroblasts, and express the chemokine receptor CXCR6. As chemokines mediate the trafficking of circulating cells to sites of injury, we studied the role of CXCR6 in mouse models of renal injury. Significantly, the kidney of CXCR6 knockout(More)
Necroptosis, an alternative mode of programmed cell death, has crucial pathophysiological roles in many diseases, but its effect on chronic kidney disease (CKD) is poorly understood. Therefore, we assessed necroptosis and its pathophysiological effects in a widely used remnant-kidney rat model. We found that necroptotic cell death and the highest level of(More)
BACKGROUND MEGSIN is a gene predominantly expressed in the renal mesangium, and is upregulated in IgA nephropathy (IgAN). Our previous study has shown that the 2093C and 2180T alleles at the 3' untranslated region (3'UTR) of the gene are associated with susceptibility to IgAN, but the relationships of these genetic variants with the clinical manifestations(More)
