Abstract Background Cervical cancer (CC) is one of the most common gynaecological malignancies all around world. The mechanisms cervical carcinoma formation remain under close scrutiny. long non-coding RNAs (lncRNA) and microRNAs (miRNAs) play important roles in controlling gene expression promoting development progression by acting as competitive endogenous RNA (ceRNA). However, lncRNA associa...

R-spondins (RSPOs) and their receptor leucine-rich repeat-containing G-protein coupled receptor 4 (LGR4) play pleiotropic roles in normal and cancer development as well as the survival of adult stem cells through potentiation of Wnt signaling. Current evidence indicates that RSPO-LGR4 functions to elevate levels of Wnt receptors through direct inhibition of two membrane-bound E3 ligases (RNF43 ...

Although extracellular control of canonical Wnt signaling is crucial for tissue homeostasis, the role of the extracellular microenvironment in modulating this signaling pathway is largely unknown. In the present study, we show that a member of the small leucine-rich proteoglycan family, biglycan, enhances canonical Wnt signaling by mediating Wnt function via its core protein. Immunoprecipitatio...

Background: In the absence of Wnt stimulation, the transcriptional cofactor b-catenin is destabilized via phosphorylation by protein kinase GSK3b in complex with Axin family members. In the ‘‘canonical’’ Wnt signaling pathway, Disheveled (Dvl) is required to functionally inhibit the activity of the GSK3b/Axin complex and thereby stabilize b-catenin. Yet, the mechanisms that underlie Wnt regulat...

Protein tyrosine kinase 7 (PTK7) is a transmembrane protein expressed in the developing Xenopus neural plate. PTK7 regulates vertebrate planar cell polarity (PCP), controlling mesodermal and neural convergent-extension (CE) cell movements, neural crest migration and neural tube closure in vertebrate embryos. Besides CE phenotypes, we now show that PTK7 protein knockdown also inhibits Wnt/β-cate...

The role of oxidized high-density lipoprotein (oxHDL) and the protective effects of adiponectin in terms of vascular calcification is not well established. This study was conducted to investigate the effects of oxHDL with regards to inflammation and vascular calcification and to determine the protective role of adiponectin in attenuating the detrimental effects of oxHDL. Cell viability, mineral...

Objective(s): To investigate and test the hypotheses that TGF-β1 enhanced myocardial differentiation through Wnt/β-catenin pathway with rat bone marrow mesenchymal stem cells (BMSCs).Materials and Methods: Lentiviral vectors carrying the TGF-β1 gene were transduced into rat BMSCs firstly. Then several kinds of experimental methods were u...

The Wnt-1 gene plays an essential role in fetal brain development and encodes a secreted protein whose signaling mechanism is presently unknown. In this report we have investigated intracellular mechanisms by which the Wnt-1 gene induces morphological changes in PC12 pheochromocytoma cells. PC12 cells expressing Wnt-1 show increased steady-state levels of the adhesive junction protein plakoglob...

Wnt-5a protein expression in primary tumors from unselected breast cancer patients has revealed a tumor suppressive function of the protein. However, in vitro experiments on human breast cancer cells have reported contradictory results, indicating both a tumor suppressive and promoting functions of Wnt-5a. This could be due to various functions of Wnt-5a in different subgroups of patients. The ...

background: dysregulation of wnt signaling has been reported in many malignancies. objective: this study was conducted to investigate the expression pattern of 14 members of the wnt gene family in different immunophenotypic subtypes of all. methods: semi-quantitative rt-pcr was performed on samples from 71 all patients and 36 age-matched healthy individuals. the all patients were categorized in...
