Porcupine is a membrane-bound O-acetyltransferase required for proper Wnt ligand secretion, and blocking Wnt ligand secretion by inhibiting porcupine activity may suppress full activation of the Wnt signaling pathway140. The small molecule Wnt-C59 is a strong and specific porcupine inhibitor and has ...

FMRP regulates a large group of neuronal mRNAs also involved in cancer progression [37]. Furthermore, FXS is the most common form of autism (ASD) and recent genome-wide exome sequencing studies of de novo variants in genes implicated in intellectual disabilities and cancer have begun to uncover...
Tumours from ApcMin/+ mice have high levels of Wnt signalling which is not permissive for proximal SI tumour formation; hence tumours form in the distal SI. Conversely, Apc1322T/+ tumours retain two β-catenin binding domains and consequently have sub-maximal Wnt signalling, permitting tumour ...
Full size image Biological function of Wnt/β-catenin signaling pathway The Wnt/β-catenin pathway plays a pivotal role in determining cell fate, promoting cell proliferation and survival, and facilitating cellular differentiation. Furthermore, this pathway critically regulates embryonic development, stem ...
Table 1 Cancer suppressor or promoter activity of Wnt pathway components and microRNAs involved in urological cancers Full size table Non-canonical Wnt signaling pathways The Wnt/Ca2+and Wnt/polarity, also known as Planar Cell Polarity (PCP) pathways are known as the "non-canonical pathways". Oth...
The potential biological of combining Wnt signaling and RA inducing sinus node-like cells Full size image The indispensable role of the Wnt signaling pathway in SAN development was shown previously. Using tracer technology, researchers found that the Wnt signaling pathway is continuously expressed in ...
27 This may be attributable to the fact that the receptor will form a homodimer, either through disulfide bonding or CRD interaction.52 It is possible that a dimerized state is used in beta-Catenin signaling, while a monomeric state is conducive to PCP pathway activation.51 Frizzled-4 Human ...
the Wnt/β-catenin signaling pathway is activated. Axin subsequently moves to the tail of LRP5/6, while dishevelled (DVL) is recruited by FZD to form a complex with APC, CK-1, and GSK-3β, leading to the accumulation of β-catenin in the cytoplasm [23,24]. The accumulated β-cateni...
Full size image The mammalian heart is developed from the lateral plate mesoderm, which fuses together to form the heart tube and subsequently organizes the ventricle and atria [18]. Wnt signaling pathways exert bi-directional regulatory effects at different stages of cardiomyogenesis. The Wnt signal...
