Wnt pathways are involved in the control of gene expression, cell behavior, cell adhesion, and cell polarity. In addition, they often operate in combination with other signaling pathways. The Wnt/beta-catenin pathway is the best studied of the Wnt pathways and is highly conserved through evolution. In this pathway, Wnt signaling inhibits the degradation of beta-catenin, which can regulate trans...

Breast cancer (BC) is one of the most widespread types affecting females, and therefore, early diagnosis critical. BC a complex heterogeneous disease affected by several key pathways. Among these, WNT proteins their frizzled receptors (FZD) have been demonstrated to be crucial in regulating number cellular molecular events tumorigenesis. The role receptor, FZD8, has received minimal attention; ...

BACKGROUND Intramyocellular lipid accumulation is strongly related to insulin resistance in humans, and we have shown that high glucose concentration induced de novo lipogenesis and insulin resistance in murin muscle cells. Alterations in Wnt signaling impact the balance between myogenic and adipogenic programs in myoblasts, partly due to the decrease of Wnt10b protein. As recent studies point ...

Osteoporosis is a frequently occurring bone remodeling disorder worldwide with one characteristic being decreasing mineral density and predisposition to fracture, which diminishes patients’ quality of life. Several studies showed that imbalance between the osteogenesis adipogenesis marrow mesenchymal stem cells (BMSCs) took part in development osteoporosis. In previous study, we found MIR22HG r...

The canonical Wnt signaling pathway is pathogenic in a variety of cancers. We previously identified aberrant expression of the Wnt pathway transcription factor and target gene lymphoid enhancer binding factor-1 (LEF1) in chronic lymphocytic leukemia (CLL). This suggested that the Wnt signaling pathway has a role in the biology of CLL. In this study, we performed a Wnt pathway analysis using gen...

Successful implantation relies on precisely orchestrated and reciprocal signaling between the implanting blastocyst and the receptive uterus. We have examined the role of the Wnt -catenin signaling pathway during the process of implantation and demonstrate that this pathway is activated during two distinct stages. Wnt -catenin signaling is first transiently activated in circular smooth muscle f...

Lately Revealed by Genome-wide association studies (GWAS) the association of TCF7L2 and Type 2 Diabetes (T2D) which implicates underlying mechanism of this Wingless (WNT) pathway effector gene in pancreatic ß-cell development. Also, further research linking TCF7L2 to T2D and impaired ß-cell mass accomplished by insulin secretory malfunction, shed light on the regulatory function of this particu...

Background—The molecular pathways that control the wound healing after myocardial infarction (MI) are not completely elucidated. One of these pathways is the Wnt/Frizzled pathway. In this study, we evaluated Frizzled as a novel therapeutic target for MI. These Frizzled proteins act as receptors for Wnt proteins and were previously shown to be expressed in the healing infarct. Methods and Result...

BACKGROUND Fine tuning of the Wnt/β-catenin signaling pathway is essential for the proper development and function of the liver. Aberrant activation of this pathway is observed in 20%-40% of hepatocellular carcinomas (HCC). Notum encodes a secreted Wnt deacylase that inhibits Wnt activity and thereby restricts the zone of activation of Wnt/β-catenin signaling. An important role of NOTUM has bee...
