We have shown previously that vascular endothelial growth factor (VEGF) synthesized by the cellular constituents of small vessels per se, viz. endothelial cells and pericytes, participates in the hypoxia-driven proliferation of both cell types (Nomura, M., Yamagishi, S., Harada, S., Hayashi, Y., Yamashima, T., Yamashita, J., Yamamoto, H. (1995) J. Biol.(More)
Induction of pluripotent stem cells from human fibroblasts has been achieved by the ectopic expression of two different sets of four genes. However, the mechanism of the pluripotent stem cell induction has not been elucidated. Here we identified a marked heterogeneity in colonies generated by the four-gene (Oct3/4, Sox2, c-Myc, and Klf4) transduction method(More)
Rev-erbalpha and retinoic acid receptor-related orphan receptor-alpha (RORalpha) are orphan nuclear receptors but their effects on transcription are opposed. Here, we show that Rev-erbalpha was expressed predominantly in vascular smooth muscle cells (VSMCs) rather than endothelial cells. Overexpression of Rev-erbalpha upregulated the expression of(More)
Centromere protein B (CENP-B) is one of the centromere DNA binding proteins constituting centromere heterochromatin throughout the cell cycles. Some components of mammalian centromeres including CENP-B are target antigens for autoimmune disease patients, often those with scleroderma. Recent isolations of CENP-B genes from human and mouse suggested that(More)
This study concerns whether advanced glycation endproducts (AGE) are related to microvascular derangement in diabetes, exemplified by pericyte loss and angiogenesis in retinopathy and by mesangial expansion in nephropathy. AGE caused a decrease in viable pericytes cultivated from bovine retina. On the other hand, AGE stimulated the growth and tube formation(More)
OBJECTIVE 15-deoxy-Delta12,14-prostaglandin J2 (15d-PGJ2), a natural ligand of the peroxisome proliferator-activated receptor-gamma (PPARgamma), has been shown to inhibit proinflammatory gene expression, but the signaling mechanisms involved remain unclear. Because retinoic acid receptor-related orphan receptor-alpha (RORalpha) has been reported to suppress(More)
Adenosine, a modulator of neuronal function in the mammalian central nervous system, exerts a neuroprotective effect via the adenosine A(1) receptor; however, its effect on neural stem cells (NSCs) remains unclear. Because adenosine is released in response to pathological conditions and NSCs play a key role in neuroregeneration, we tested the hypothesis(More)
Retinoic acid receptor-related orphan receptor-alpha (RORalpha) is a nuclear orphan receptor. Adenovirus-mediated overexpression of RORalpha1 and RORalpha4 suppressed tumor necrosis factor-alpha (TNF-alpha)-induced expression of vascular cell adhesion molecule-1 (VCAM-1) and intracellular adhesion molecule-1 (ICAM-1) in human umbilical vein endothelial(More)
Presented here is an antisense-oriented method for functional gene screening, which we propose naming 'antisense display'. In principle, it consists of four steps: (i) preparation of phosphorothioate antisense repertoires that would correspond to the Kozak's consensus sequence, (ii) subgroup screening to identify active antisense molecules that could cause(More)
