View SamplesWe screened a number of interferon inducible genes that may be involved in impeding HBV replication and found an anti-HBV activity in ISG20. ISG20 is an IFN-inducible 3- to 5-exonuclease, that degrades DNA and RNA and reduces antigen production in hepatocyte-derived cells
Interferon-stimulated gene of 20 kDa protein (ISG20) degrades RNA of hepatitis B virus to impede the replication of HBV in vitro and in vivo.

View SamplesGlioma initiating cells (GICs) are considered responsible for the therapeutic resistance and recurrence of malignant glioma. To clarify the molecular mechanism of GIC maintenance/differentiation, we established GIC clones from GBM patient tumors having the potential to differentiate into malignant gliomas in mouse intracranial xenograft, and established an in vitro glioma induction system by using serum stimulation.
Glioma initiating cells form a differentiation niche via the induction of extracellular matrices and integrin αV.

View SamplesEndothelial-to-mesenchymal transition (EndMT) in which endothelial cells lose their characteristics and acquire mesenchymal property has recently been recognized as a driver of disease progression in wide range of pathologies. However, the regulatory mechanism of EndMT has not been fully understood. Here, we found that combined knockdown of two ETS family transcription factors, ERG and FLI1, induced EndMT. Hence, we analyzed functions of ERG and FLI1 using gene expression microarray and ChIP-seq to elucidate the regulatory mechanism of EndMT.

View SamplesOral squamous cell carcinoma (OSCC) has a very poor prognosis due to its highly invasive nature, and 5-year survival rate has not changed apparently for the past 30 years. Although cylindromatosis (CYLD) is thought as a potent tumor suppressor, its biological and clinical significances in OSCC are largely unknown. The aim of this study was to clarify roles of CYLD in OSCC progression. Our immunohistochemical analyses revealed that CYLD expression was significantly reduced at invasive lesions in OSCC tissues whereas it was conserved in normal epithelium and carcinoma in situ. Accordingly, downregulation of CYLD by siRNA led to an acquisition of mesenchymal state and increased migratory and invasive activities in OSCC cells and HaCaT keratinocytes. Interestingly, CYLD knockdown promoted TGF-beta signaling by inducing TGF-beta receptor I (ALK5) stabilization in a cell autonomous fashion. In addition, the response to exogenous TGF-beta stimulation was enhanced by CYLD downregulation. The invasive phenotype induced by CYLD knockdown were completely blocked by an ALK5 inhibitor. Furthermore, lower CYLD expression was significantly associated with deep invasion, poor overall survival, and increased Smad3 phosphorylation which is an indicator of TGF-beta signaling activation in invasive OSCC. These findings suggest that downregulation of CYLD promotes invasion with mesenchymal transition via ALK5 stabilization in OSCC cells.

View SamplesFibrocytes (fibroblastic leukocytes) are recently identified as unique hematopoietic cells with features of both macrophages and fibroblasts. Fibrocytes are known to contribute to the remodeling or fibrosis of various injured tissues. However, their role in viral infection is not fully understood. Here we show that differentiated fibrocytes are phenotypically distinguishable from macrophages but can be infected with HIV-1. Importantly, fibrocytes exhibited persistently infected cell-like phenotypes, the degree of which was more apparent than macrophages. The infected fibrocytes produced replication-competent HIV-1, but expressed HIV-1 mRNA at low levels and strongly resisted HIV-1-induced cell death, which enabled them to support an extremely long-term HIV-1 production at low but steady levels. More importantly, our results suggested that fibrocytes were susceptible to HIV-1 regardless of their differentiation state, in contrast to the fact that monocytes become susceptible to HIV-1 after the differentiation into macrophages. Our findings indicate that fibrocytes are the previously unreported HIV-1 host cells, and suggest the importance of considering fibrocytes as one of long-lived persistently infected cells for curing HIV-1.
