In-depth characterization of the Wnt-signaling/β-catenin pathway in an in vitro model of Barrett’s sequence

BMC Gastroenterology, 2019
Background An altered Wnt-signaling activation has been reported during Barrett’s esophagus progression, but with rarely detected mutations in APC and β-catenin (CTNNB1) genes.

Pathway selectivity in Frizzleds is achieved by conserved micro-switches defining pathway-determining, active conformations

Nature Communications, 2023
The class Frizzled of G protein-coupled receptors (GPCRs), consisting of ten Frizzled (FZD1-10) paralogs and Smoothened, remains one of the most enigmatic GPCR families.

Accurate Delivery of Mesenchymal Stem Cell Spheroids With Platelet‐Rich Fibrin Shield: Enhancing Survival and Repair Functions of Sp‐MSCs in Diabetic Wound Healing

Advanced Science, EarlyView.
Autologous plasma‐derived platelet‐rich fibrin (PRF) is prepared as a protective shield for mesenchymal stem cell spheroids (Sp‐MSCs). PRF forms a fibrin shield to protect Sp‐MSCs from the oxidative stress environment. The nutrients in PRF, particularly the α‐granules, can enhance the repair function of Sp‐MSCs.

Novel Para‐Phenylenediamine‐Based Derivatives as Receptor Tyrosine Kinase‐like Orphan Receptor 1 (ROR1) Inhibitors: An In Vitro Preliminary Characterization

ChemMedChem, EarlyView.
ROR1 represents a promising target for the development of novel antiproliferative compounds, giving its high expression in different cancer cell lines. The present study describes the workflow leading to the design, synthesis, and characterization of a series of para‐phenylenediamine‐based compounds able to interact with the target kinase, inhibiting ...

β‐Catenin localization in the ctenophore Mnemiopsis leidyi suggests an ancestral role in cell adhesion and nuclear function

Developmental Dynamics, EarlyView.
Abstract Background The emergence of multicellularity in animals marks a pivotal evolutionary event, which was likely enabled by molecular innovations in the way cells adhere and communicate with one another. β‐Catenin is significant to this transition due to its dual role as both a structural component in the cadherin–catenin complex and as a ...

Differential sensitivity of midline development to mitosis during and after primitive streak extension

Developmental Dynamics, EarlyView.
Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).

Structures of Wnt-antagonist ZNRF3 and its complex with R-spondin 1 and implications for signaling.

PLoS ONE, 2013
Zinc RING finger 3 (ZNRF3) and its homolog RING finger 43 (RNF43) antagonize Wnt signaling in adult stem cells by ubiquitinating Frizzled receptors (FZD), which leads to endocytosis of the Wnt receptor.

The role of dexamethasone in mediating the contradictory effects of Wnt antagonists SFRP2 and SFRP3 on human hair follicle growth

Scientific Reports, 2023
Stress can be one of the leading causes of hair loss. Stress related hormones, glucocorticoids (GCs), secretion by hair follicle have been mentioned in literature and proven to exert an inhibitory effect on hair follicle cells growth by modulating the ...

Analysis of Wnt8 for neural posteriorizing factor by identifying Frizzled 8c and Frizzled 9 as functional receptors for Wnt8

Mechanisms of Development, 2003
The dorsal ectoderm of vertebrate gastrula is first specified into anterior fate by an activation signal and posteriorized by a graded transforming signal, leading to the formation of forebrain, midbrain, hindbrain and spinal cord along the anteroposterior (A-P) axis.
