Cryo-EM structure of human Wntless in complex with Wnt3a

open access: yesNature Communications, 2021
The transmembrane protein Wntless (WLS) is essential for the secretion of Wnt proteins, which are signaling molecules of the Wnt signaling pathways. Here, the authors present the 2.2 Å cryo-EM structure of human WLS in complex with Wnt3a and discuss ...

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

open access: yesMolecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

Ubiquitin ligase RNF146 regulates tankyrase and Axin to promote Wnt signaling.

open access: yesPLoS ONE, 2011
Canonical Wnt signaling is controlled intracellularly by the level of β-catenin protein, which is dependent on Axin scaffolding of a complex that phosphorylates β-catenin to target it for ubiquitylation and proteasomal degradation.

Genetic dissection of differential signaling threshold requirements for the Wnt/β-catenin pathway in vivo [PDF]

open access: yes, 2010
Contributions of null and hypomorphic alleles of Apc in mice produce both developmental and pathophysiological phenotypes. To ascribe the resulting genotype-to-phenotype relationship unambiguously to the Wnt/beta-catenin pathway, we challenged the allele

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

open access: yesFEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Probing Wnt pathway and functional signal in equine melanocytic neoplasms through quantitative proteomics and immunohistochemistry

open access: yesBMC Veterinary Research
Background Equine melanocytic neoplasm (EMN) is a skin tumor commonly observed in grey horses. Limited research has yet to investigate proteomic profiles of EMN, particularly in the early stages and their expression patterns. This study, therefore, aimed

Spreading around a Wnt protein [PDF]

open access: yesJournal of Cell Biology, 2013
![Figure][1] In a fly lacking Trol, arrows and arrowheads mark the extra boutons in a neuromuscular junction stained for pre- (purple) and postsynaptic (green) markers. Aproteoglycan helps disperse Wnt proteins during development of the neuromuscular junction, [Kamimura et al.][2 ...

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

WNT Signaling in Tumors: The Way to Evade Drugs and Immunity

open access: yesFrontiers in Immunology, 2019
WNT/β-catenin signaling is involved in many physiological processes. Its implication in embryonic development, cell migration, and polarization has been shown.
