Constitutive activation of canonical WNT-TCF signaling is implicated in multiple diseases, including intestine and lung cancers, but there are no WNT-TCF antagonists in clinical use. We have performed a repositioning screen for WNT-TCF response blockers aiming to recapitulate the genetic blockade afforded by dominant-negative TCF. We report that Ivermectin inhibits the expression of WNT-TCF tar...

Specific recognition of DNA by transcription factors is essential for precise gene regulation. In Wingless (Wg) signaling in Drosophila, target gene regulation is controlled by T cell factor (TCF), which binds to specific DNA sequences through a high mobility group (HMG) domain. However, there is considerable variability in TCF binding sites, raising the possibility that they are not sufficient...

TCF transcription factors are mediators of the WNT signaling pathway and are antagonized by the transforming growth factor beta signaling pathway. Here human TCF-3 has been cloned and characterized. Differential expression analyses of TCF genes in gastric cancer revealed that TCF-1 was expressed in most cases of primary gastric cancer at almost the same level as in normal gastric mucosa and tha...

-Catenin and T cell factor (Tcf) are distal components of the highly conserved Wnt pathway that govern cell fate and proliferation in lower organisms. Thus, we hypothesized that the regulation of -catenin and Tcf played a critical role in vascular remodeling. The first objective was to define -catenin expression in vascular smooth muscle cells (VSMCs) after balloon injury. Indeed, -catenin mRNA...

When human alveolar macrophages (AM) lavaged from healthy donors were incubated in medium with or without lipopolysaccharide (LPS) or muramyl dipeptide, they released a factor(s) responsible for tumor cell killing. The activity of the tumor cytolytic factor(s), called TCF, was determined by radioactive release assay. Human AM released variable amounts of TCF into the culture medium without any ...

Previous examination of the effect of TCF-4 on transcription of the human immunodeficiency virus type 1 (HIV-1) promoter in human astrocytic cells found that TCF-4 affects the HIV-1 promoter through the GC-rich domain (nt -80 to nt -68). Here, the physical interaction and a functional consequence of TCF4-Sp1 contact were characterized. It was shown that expression of TCF-4 in U-87 MG (human ast...

The relationships between the intensification rate (IR) and size configuration of tropical cyclones (TCs) are investigated. Theoretically, intensity, configuration, relative vorticity TCs intrinsically linked. TC fullness (TCF) is used to quantify can be expressed as product critical (TCF0) ratio (Rf). TCF0 represents fundamental constraint on shared by at a given intensity lower limit fullness...

In a product market with price-sensitive demand, we examine supply chain consisting of one manufacturer and capital-constrained retailer. The retailer may purchase by borrowing securing confirmed warehouse financing (CWF) from competitive bank or the manufacturer's trade credit (TCF), provided that it is also to latter's benefit extend TCF. We obtain optimal pricing decision in two modes under ...

Cdx2 is an intestine-specific transcription factor known to regulate proliferation and differentiation. We have reported previously that Cdx2 limits the proliferation of human colon cancer cells by inhibiting the transcriptional activity of the beta-catenin-T-cell factor (TCF) bipartite complex. Herein we further elucidate this mechanism. Studies with a classic Cdx2 target gene and a canonical ...
