Objectives: Fibromatosis of the breast is an uncommon neoplasm with potential for local recurrence. Treatment has traditionally been surgical excision with current trends toward conservative management. Given the option of observation after diagnosis by core needle biopsy (CNB), we sought to evaluate the accuracy of CNB for diagnosing fibromatosis. Methods: We identified a total of 31 cases in which fibromatosis had been diagnosed or included in the differential diagnosis on a CNB, an excision, or both...

Skin is a highly plastic tissue that undergoes tissue turnover throughout life, but also in response to injury. YAP and Hedgehog signalling play a central role in the control of epidermal stem/progenitor cells in the skin during embryonic development, in postnatal tissue homeostasis and in skin carcinogenesis. However, the genetic contexts in which they act to control tissue homeostasis remain mostly unresolved. We provide compelling evidence that epidermal YAP and Hedgehog/GLI2 signalling undergo positive regulatory interactions in the control of normal epidermal homeostasis and in basal cell carcinoma (BCC) development, which in the large majority of cases is caused by aberrant Hedgehog signalling activity...

CD24 (cluster of differentiation 24) is a small heavy glycosylated protein, which is overexpressed in many cancer and some cancer stem cells and is associated with the development, invasion, and metastasis of cancer cells. The exact role of CD24 in these processes is not fully understood, however, in this article, it has been tried to present collection of cancer-related mechanisms attributed to CD24. Based on the literature, CD24 dis-regulates different signaling pathways in various cancer cells, including; Src kinases, STAT3, EGFR, Wnt/β-catenin and MAPK...

Purpose: Tientsin Albino 2 (TA2) mice have a high incidence of spontaneous breast cancer. Tumor initiation is related to mouse mammary tumor virus (MMTV) infection. MMTV is hormonally regulated and may promote tumor formation via Wnt/β-catenin signaling pathway. This study attempts to clarify the relationship between β-catenin expression and the initiation and metastasis of spontaneous breast cancer in TA2 mice. Materials and Methods: Pathological samples illustrating the development of spontaneous breast cancer in TA2 mice were collected and the presence of virus particles was verified in the cancer tissue by electron microscope...

We examined the prognostic significance of Epidermal Growth Factor-like repeats and Discoidin I-Like Domains 3 (EDIL3) expression and its correlations with mesenchymal phenotype and microvessel density in non-small cell lung carcinoma (NSCLC). A total of 268 NSCLC specimens were evaluated retrospectively by immunohistochemical staining for EDIL3, EMT markers (e-cadherin, β-catenin, and vimentin), and CD31 to measure microvessel density. EDIL3, e-cadherin, β-catenin, and vimentin were expressed in 16%, 22...

Lipopolysaccharide (LPS) is known to mediate angiogenic effects in endothelial cells. The underlying mechanisms, however, remain largely unknown. In this study, we showed that LPS induced high motility group box protein 1 (HMGB1) secretion in human pulmonary microvascular endothelial cells (HPMECs). Knockdown and overexpression of HMGB1 by adenoviral vectors effectively inhibited and promoted LPS-induced HPMEC migration and capillary-like tube formation, respectively. On the other hand, HMGB1 exerted an inhibitory effect on LPS-suppressed expression of platelet-endothelial cell adhesion molecule (CD31) and p120 catenin (p120); HMGB1 knockdown reversed this effect...

BACKGROUND: The epithelial-mesenchymal transition (EMT) is a crucial event in the development of renal interstitial fibrosis (RIF). A growing body of evidence indicates that β-catenin plays an important role in various types of fibrosis. Although members of the microRNA (miRNA)-200 family have been suggested to suppress EMT in cancer and fibrosis, the function of miRNA-200a in regulating the progression of RIF is unknown. We speculate that miRNA-200a may hinder this progression through the suppression of β-catenin...

Wnt signaling is hyper-activated in most of human cancers including colorectal carcinoma (CRC). Therefore, the introduction of new regulators for Wnt pathway possesses promising diagnostic and therapeutic applications in cancer medicine. Bioinformatics analysis introduced hsa-miR-103a, hsa-miR-1827, and hsa-miR-137 as potential regulators of Wnt signaling pathway. Here, we intended to examine the effect of these human miRNAs on Wnt signaling pathway components, on the cell cycle progression in CRC originated cell lines and their expression in CRC tissues...

Metastasis is the major cause of the poor prognosis of hepatocellular carcinoma (HCC), and increasing evidence supports the contribution of miRNAs to cancer progression. However, the exact relationship between the level of miR-1301 expression and HCC cell migration, invasion, and angiogenesis remains largely unknown. Quantitative PCR was used to evaluate the level of miR-1301 expression in HCC tissues and cell lines. Transwell and tube-formation assays were used to measure the effects of miR-1301 on HCC cell migration and invasion, and angiogenesis, respectively...

Aberrant activation of Wnt/β-catenin signaling leads to increased cell proliferation and survival and promotes the development of various human tumors, including glioma, one of the most common primary brain tumors. The treatment efficacy of many anticancer drugs remains limited or unsatisfactory and it is urgently necessary to develop effective and low-toxicity anticancer drugs or strategies, especially for glioma. Here, we report that diallyl trisulfide suppresses survival, migration, invasion and angiogenesis in glioma cells...

Osteoblast differentiation is regulated through the successive activation of signaling molecules by a complex interplay of extracellular signals such as bone morphogenetic protein (BMP) and Wnt ligands. Numerous studies have identified natural as well as synthetic compounds with osteogenic activity through the regulation of either BMP/SMADs or the Wnt/β-catenin pathway. Here, we attempted to isolate small molecules that concurrently activated both SMADs and β-catenin, which led to the discovery of a novel potent osteogenic compound, DMP-PYT...

Stem cells reside in niches where spatially restricted signals maintain a delicate balance between stem cell self-renewal and differentiation. Wnt family proteins are particularly suited for this role as they are modified by lipids, which constrain and spatially regulate their signalling range. In recent years, Wnt/β-catenin signalling has been shown to be essential for the self-renewal of a variety of mammalian stem cells. In this review, we discuss Wnt-responsive stem cells in their niche, and mechanisms by which Wnt ligands are presented to responsive cells...

We analyzed chromatin dynamics and transcriptional activity of human embryonic stem cell (hESC)-derived cardiac progenitor cells (CPCs) and KDR(+)/CD34(+) endothelial cells generated from different mesodermal origins. Using an unbiased algorithm to hierarchically rank genes modulated at the level of chromatin and transcription, we identified candidate regulators of mesodermal lineage determination. HOPX, a non-DNA-binding homeodomain protein, was identified as a candidate regulator of blood-forming endothelial cells...

Although accumulating evidence indicates that both β-catenin and osterix (Osx) are essential for bone and tooth development, few studies have investigated the interaction of these two key proteins in the context of cementogenesis. In this study, we used transgenic mice with constitutively active β-catenin and inactive Osx in the dental mesenchyme to address this question. We found that cementoblasts with constitutively active β-catenin require Osx to produce excessive cellular cementum, and that ablation of Osx prevents this abnormal accumulation...

Lichens are symbiotic organisms that produce various secondary metabolites. Here, different lichen extracts were examined to identify secondary metabolites with anti-migratory activity against human lung cancer cells. Everniastrum vexans had the most potent inhibitory activity, and atranorin was identified as an active subcomponent of this extract. Atranorin suppressed β-catenin-mediated TOPFLASH activity by inhibiting the nuclear import of β-catenin and downregulating β-catenin/LEF and c-jun/AP-1 downstream target genes such as CD44, cyclin-D1 and c-myc...

Activation of Wnt/β-catenin signaling plays a central role in the development and progression of colorectal cancer (CRC). The Wnt-transcription factor, TCF7L2, is overexpressed in primary rectal cancers that are resistant to chemoradiotherapy (CRT) and TCF7L2 mediates resistance to CRT. However, it is unclear whether the resistance is mediated by a TCF7L2 inherent mechanism or Wnt/β-catenin signaling in general. Here, inhibition of β-catenin by siRNAs or a small molecule inhibitor (XAV-939) resulted in sensitization of CRC cells to CRT...

During vertebrate embryogenesis, vascular endothelial cells (ECs) and primitive erythrocytes become specified within close proximity in the posterior lateral plate mesoderm (LPM) from a common progenitor. However, the signaling cascades regulating the specification into either lineage remain largely elusive. Here, we analyze the contribution of β-catenin dependent Wnt signaling to EC and erythrocyte specification during zebrafish embryogenesis. We generated novel β-catenin dependent Wnt signaling reporters which, by using destabilized fluorophores (Venus-Pest, dGFP), specifically allow us to detect Wnt signaling responses in narrow time windows as well as in spatially restricted domains, defined by Cre recombinase expression (Tg(axin2BAC:Venus-Pest)(mu288); Tg(14TCF:loxP-STOP-loxP-dGFP)(mu202))...
