colorectal cancer is one of the most common malignancy in the world and the second cancer-related death, many molecular and genetic aspects of this disease have been cleared as chromosomal instability and the role of some key proteins as wnt/? catenin, trypsin and others. also recently the role of folate turnover and some neurotransmitters as serotonin were also considered. the scope of this re...

It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...

materials and methods an oligogearray® (an oligonucleotide-based gene expression array platform) containing 126 wnt signaling pathway-related genes was used to compare gene expressions between primary hcc and adjacent non-tumorous liver tissues from 10 patients with hcc. selected differential genes were identified with real-time rt-pcr and immunohistochemistry (ihc). in particular, the protein ...

Animals’ Wnt signaling pathways are highly preserved signal transduction pathways, which play a crucial role in embryogenesis and adult tissue homeostasis. This chapter reviews the three major focusing on some critical proteins Wnt/β-catenin path terms of their evolution act as gateway between extracellular, cytoplasmic, nuclear components to transmit pathways. The Frizzled (FZD) family G-prote...

Objective(s): To analyze the potential influences of propofol on the oxidative stress of H2O2-induced human esophageal squamous cell carcinoma (ESCC) Eca109 cell through mediating the Wnt/β-catenin signaling pathway.Materials and Methods: Eca109 cells were classified into 5 groups: Control group, H2O2 group, Propofol + H2O2 group, Dkk1 (Dickkopf-1, Wnt/β-catenin pathway antagonist) + H2O2 group...

Wnt-5a is a non-transforming Wnt protein. Since Wnt-5a mRNA and protein levels differ within and between tumours, the potential of Wnt-5a as a prognostic factor has been debated. We have previously shown that the lack of Wnt-5a protein is a predictor of shorter disease-free survival in human breast cancer. Recently, however, we also showed that the breast tumours lacking Wnt-5a protein had a hi...

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...

Micro-vascular complications such as diabetic nephropathy (DN) develop in patients with uncontrolled T1DM. Low density lipoprotein receptor-related protein 5 (LRP5) is the co-receptor ligand of Wnt signaling pathway. Many single nucleotide variants have been identified human LRP5 gene and were reported to be associated metabolic disorders. The Wnt/β-catenin pathway has proposed play an importan...

Abstract Wntless (WLS), an evolutionarily conserved multi-pass transmembrane protein, is essential for secretion of Wnt proteins. Wnt-triggered signaling pathways control many crucial life events, whereas aberrant tightly associated with human diseases including cancers. Here, we report the cryo-EM structure WLS in complex Wnt3a, most widely studied Wnt, at 2.2 Å resolution. The domain bears a ...
