background: the canonical wnt signal transduction (or the wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. beta-catenin is the central component of this signaling pathway. the activation of wnt/β-catenin signaling results in the cytoplasmic and nuclear accumulation of β-catenin. in the nucleus, β-catenin interacts with the tcf/lef transcription fa...

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...

Background: Hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. On the other hand, mesenchymal stem cells (MSCs) are regarded as potent cells with a property of cartilage regeneration. We aimed to optimize marrow-derived MSC chondrogenic culture using a small bioactive molecule referred to as BIO. Methods: MSCs from the ma...

On pathological stress, the heart reactivates several signaling pathways that traditionally were thought to be operational only in the developing heart. One of these pathways is the WNT signaling pathway. WNT controls heart development but is also modulated during adult heart remodeling. This review summarizes the currently available data regarding WNT signaling during left ventricular (LV) rem...

Purpose: Hepatocellular carcinoma (HCC) is a heterogeneous cancer with active Wnt signaling. Underlying biologic mechanisms remain unclear and no drug targeting this pathway has been approved todate.Weaimed to characterizeWnt-pathway aberrations inHCCpatients, and to investigate sorafenib as a potential Wnt modulator in experimental models of liver cancer. Experimental Design: The Wnt-pathway w...

The multilineage commitment of mesenchymal stem cells (MSCs) is controlled via unknown mechanisms. In this study, we investigated the regulation of the differentiation of MSCs into chondrocytes via the Wnt signaling pathway. Overexpression of WNT3A in MSCs activated both the canonical and non-canonical Wnt pathways, which were responsible for different WNT3A-induced outcomes. WNT3A promoted MSC...

Mounting evidence has indicated microRNA (miR) dysregulation and the Wnt/β-catenin signaling pathway jointly drive carcinogenesis, cancer metastasis, and drug-resistance. The current review will focus on the role of the crosstalk between miRs and the Wnt/β-catenin signaling pathway in cancer development. MiRs were found to activate or inhibit the canonical Wnt pathway at various steps. On the o...

Wnt and its intracellular effector b-catenin regulate developmental and oncogenic processes. Using expression cloning to identify novel components of the Wnt pathway, we isolated casein kinase I« (CKI«). CKI« mimicked Wnt in inducing a secondary axis in Xenopus, stabilizing b-catenin, and stimulating gene transcription in cells. Inhibition of endogenous CKI« by kinase-defective CKI« or CKI« ant...
