background: this research studies the effects of activation and inhibition of wnt3a signaling pathway in buffalo (bubalus bubalis) embryonic stem (es) cell-like cells. materials and methods: to carry on this experimental study, the effects of activation and inhibition of wnt3a signaling in buffalo es cell-like cells were examined using bio (0.5 mm) combined with wnt3a (200 ng/ml), as an activat...
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...
backgroud: protein-protein interaction, plays a key role in signal transduction in signaling pathways. different approaches are used for prediction of these interactions including experimental and computational approaches. in conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins interact which ca...
Hepatocellular carcinoma (HCC) is one of the most lethal malignancies in the world. Several signaling pathways, including the wingless/int-1 (Wnt) signaling pathway, have been shown to be commonly activated in HCC. The Wnt signaling pathway can be triggered via both catenin β1 (CTNNB1)-dependent (also known as "canonical") and CTNNB1-independent (often referred to as "non-canonical") pathways. ...
The Wnt pathway plays a critical role in development and differentiation of many tissues, such as the gut, hair follicles, and bone. Increasing evidence indicates that Wnts may function as key regulators in osteogenic differentiation of mesenchymal stem cells and bone formation. Conversely, aberrant Wnt signaling is associated with many osteogenic pathologies. For example, genetic alterations i...
Wnt signaling affects both bone modeling, which occurs during development, and bone remodeling, which is a lifelong process involving tissue renewal. Wnt signals are especially known to affect the differentiation of osteoblasts. In this review, we summarize recent advances in understanding the mechanisms of Wnt signaling, which is divided into two major branches: the canonical pathway and the n...
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...
Porcine circovirus-like virus P1 is an important pathogen of the current pig industry, the infection mechanism is not entirely clear. Wnt signaling pathway plays an important role in the growth of young animals and infection of some viruses. This study was designed to demonstrate the effects of P1 infection on the Wnt signaling pathway. In vivo experiments, we demonstrated the down-regulatory e...
The Wnt signaling pathways have been conserved throughout evolution and regulate cell proliferation, morphology, motility, and fate during embryonic development. These pathways also play important roles throughout adult life to maintain homeostasis of tissues including skin, blood, intestine, and brain by regulating somatic stem cells and their niches. Aberrant regulation of the Wnt pathway lea...
