The Wnt/β-catenin signaling pathway plays a crucial role in neural development, axonal guidance, neuropathic pain remission and neuronal survival. In this study, we initially examined the effect of rapamycin on the Wnt/β-catenin signaling pathway after spinal cord injury, by intraperitoneally injecting spinal cord injured rats with rapamycin over 2 days. Western blot analysis and immunofluoresc...

The Wnt signaling pathway provides key information during development of vertebrates and invertebrates, and mutations in this pathway lead to various forms of cancer. Wnt binding to its receptor causes the stabilization and nuclear localization of beta-catenin. Nuclear beta-catenin then functions to activate transcription in conjunction with the transcription factor TCF. A recent report has cha...

The Wnt/beta-catenin signal transduction pathway regulates a broad range of developmental processes. Aberrant activation of the Wnt pathway leads to cancer and degenerative diseases. beta-catenin is a key signaling molecule that is frequently used as a direct monitor of Wnt pathway activation. This paper describes a multi-parametric method for quantitative analysis of cellular beta-catenin prot...

Anaberrant Wnt/β-catenin signaling pathway is frequently implicated in tumorigenesis. However, whether the Wnt/β‑catenin pathway plays a role in resistance to antitumor chemotherapy drugs remains unknown. In the present study, the process of autophagy was assessed following overexpression of the autophagy‑associated gene Beclin 1 in gemcitabine‑induced MG63 human osteosarcoma cells. Autophagy‑a...

The rising incidence and poor prognosis of colorectal cancer have aroused substantial interest in novel chemopreventive strategies. Interestingly, treatment of ulcerative colitis with mesalazine, which displays few side effects during long-term treatment, is associated with a reduced incidence of colorectal cancer, but its molecular mechanism is not known. The effect of mesalazine on the Wnt/be...

β-Catenin is a major transducer of the Wnt signaling pathway, which is aberrantly expressed in colorectal and other cancers. Previously, we showed that β-catenin is downregulated by the 90K glycoprotein via ISGylation-dependent degradation. However, the further mechanisms of β-catenin degradation by 90K-mediated ISGylation pathway were not investigated. This study aimed to identify the β-cateni...

Osteosarcoma is a high-grade bone sarcoma with strong invasive ability. However, treatment with traditional chemotherapeutic drugs is limited by low tolerability and side effects. Resveratrol has been reported previously to have selective antitumor effect on various tumor cells while little is known about its effects and underlying mechanism in osteosarcoma biology. In this study, we found that...

Glypicans are members of the heparan sulfate proteoglycans (HSPGs) and are involved in various growth factor signaling mechanisms. Although HSPGs affect the β-catenin-dependent and -independent pathways of Wnt signaling, how they regulate distinct Wnt pathways is not clear. It has been suggested that the β-catenin-dependent pathway is initiated through receptor endocytosis in lipid raft microdo...

The Wnt/β-catenin signaling pathway controls several biological processes throughout development and adult life. Dysregulation of Wnt/β-catenin signaling underlies a wide range of pathologies in animals and humans, including cancer in different tissues. In this review, we provide an update of the Wnt/β-catenin signaling pathway and the possible roles of the Wnt/β-catenin signaling in the biolog...
