Peroxisome proliferator-activated receptor coactivator-1 alpha (PGC-1α) is a transcriptional coactivator that regulates energy metabolism and mitochondrial biogenesis. Recently, mitochondrial dysfunction has been indicated as an established risk factor for the development of renal fibrosis. However, whether PGC-1α is involved in the pathogenesis of renal fibrosis is unknown. In this study, we treated NRK-49F (normal rat kidney fibroblast) cells with transforming growth factor-beta 1 (TGF-β1) for 24h to establish an in vitro fibrosis model...

Chaperonin containing tailless complex polypeptide 1 (CCT) is a molecular chaperone consisting of eight distinct protein subunits, that when oligomeric is essential for the folding of newly synthesized tubulin and actin. In addition to folding, CCT activity includes functions of individual subunits in their monomeric form. For example, when CCTδ monomer levels are increased in cultured mammalian cells, numerous cell surface protrusions are formed from retraction fibres, indicating that an underlying function for the CCTδ monomer exists...

Tau pathology in Alzheimer's disease (AD) includes hyperphosphorylation and truncation of tau. Phosphorylation at S422 is found to suppress truncation of tau at D421 that leading to the generation of ΔTau. However, the interrelation between hyperphosphorylation and generation of ΔTau in AD remains elusive. In current study, staurosporine (Stau) induced ΔTau generation by caspases in SH-SY5Y cells with tau overexpression was found to be accompanied by a dramatic dephosphorylation at S422 and the epitope of the diagnostic antibody AT8 (S199+S202+T205), but a moderate dephosphorylation of PHF1 (S396+S404) epitope...

One of the major challenges in Glioblastoma (GBM) therapy relates with the existence of glioma stem-like cells (GSCs), known to be chemo- and radio-resistant. GSCs and non-stem GBM cells have the ability to interchange, emphasizing the importance of identifying common molecular targets among those cell sub-populations. Nucleolin overexpression has been recently associated with breast cancer sub-populations with different stem-like phenotype. The goal of this work was to evaluate the potential of cell surface nucleolin as a target in GBM cells...

Metabolic dysfunction is a hallmark of cardiac hypertrophy and heart failure. During cardiac failure, the metabolism of cardiomyocyte switches from fatty acid oxidation to glycolysis. However, the roles of key metabolic enzymes in cardiac hypertrophy are not understood fully. Here in the present work, we identified Aldolase A (AldoA) as a core regulator of cardiac hypertrophy. The mRNA and protein levels of AldoA were significantly up-regulated in transverse aortic constriction (TAC)- and isoproterenol (ISO)-induced hypertrophic mouse hearts...

Lung fibroblasts play critical roles in fibrotic procedures and contribute to lung fibrosis. Several studies indicated that thrombin, a disintegrin and metalloproteinase 17 (ADAM17), and connective tissue growth factor (CTGF) participate in the formation of pulmonary fibrosis. In this study, we examined the involvement of the ADAM17/epidermal growth factor receptor (EGFR)/extracellular signal-regulated kinase (ERK) pathway in thrombin-stimulated CTGF manifestation in human lung fibroblasts (WI-38). We found that cells treated with thrombin significantly increased ADAM17 expression, ADAM17 and c-Jun phosphorylation in time-dependent manners...

Endothelial progenitor cell (EPC) has potential to attenuate pulmonary inflammation and injury. As a pivotal paracrine entity of stem cells, whether EPC-derived exosomes (EPC-Exos) contribute to acute lung injury (ALI) remains unknown. Exosomes were purified from conditional medium of EPCs, and then characterized by electron micrograph and immunoblotting. A model of ALI was induced by lipopolysaccharide (LPS) and then rats were transplanted with EPC-Exos. The underlying mechanisms of action of EPC-Exos were examined in vitro endothelial functional assays including the TEER, proliferation (CKK-8), angiogenesis and migration...

Myocardial hypoxia-induced endothelial cell apoptosis contributes to cardiac dysfunction, such as myocardial infarction (MI), myocardial ischemia, and heart failure. Thus, it is important to investigate the molecular mechanisms of vascular endothelial cells (VECs) during exposure to hypoxia. SP-1 is an important regulator of cytokines associated with cell functions. We found that SP-1 expression increased in human umbilical vein endothelial cells (HUVECs) exposed to hypoxia by western blot. Then the SP-1 siRNA was transfected into HUVECs under hypoxic condition...

Understanding mechanisms in lineage differentiation is critical for organ development, pathophysiology and oncogenesis. To determine whether microRNAs (miRNA) may serve as drivers or adjuncts in hepatic differentiation, we studied human embryonic stem cell-derived hepatocytes and primary hepatocytes representing fetal or adult stages. Model systems were used for hepatic lineage advancement or regression under culture conditions with molecular assays. Profiles of miRNA in primary fetal and adult hepatocytes shared similarities and distinctions from pluripotent stem cells or stem cell-derived early fetal-like hepatocytes...

The continuously decreasing willingness for liver donation aggravates treatment of end-stage liver diseases requiring organ transplantation as the only curative strategy. Cell therapy approaches using human hepatocytes or stem cell-derived hepatocyte-like cells may be a therapeutic option out of this dilemma. ABCB5-positive mesenchymal stromal cells from human skin featured promising potential to treat immune-mediated diseases. Since most of chronic liver diseases involve exaggerating immune mechanisms, it was the aim to demonstrate in this study, whether ABCB5+ stem cells may serve as a resource to generate hepatocytic cells for application in liver cell transplantation...
