Wnt/beta-catenin signaling controls development of the blood–brain barrier

open access: yes, 2008
The blood–brain barrier (BBB) is confined to the endothelium of brain capillaries and is indispensable for fluid homeostasis and neuronal function. In this study, we show that endothelial Wnt/beta-catenin (beta-cat) signaling regulates induction and ...

Гетерозиготна делеція гена β-катеніну у ранньому кардіогенезі спричиняє затримку росту серця і порушує кінетику канонічного Wnt сигналінгу

open access: yesФактори експериментальної еволюції організмів, 2017
Aim. In our present work, we have analyzed newborn and embryonic heart under the β-catenin haploinsufficiency. Methods. Beta-catenin conditional knockout mice were bred with α-MHC-Cre transgenic mice.

An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

open access: yesAdvanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Heterogeneous beta-catenin activation is sufficient to cause hepatocellular carcinoma in zebrafish

open access: yesBiology Open, 2019
Up to 41% of hepatocellular carcinomas (HCCs) result from activating mutations in the CTNNB1 gene encoding β-catenin. HCC-associated CTNNB1 mutations stabilize the β-catenin protein, leading to nuclear and/or cytoplasmic localization of β-catenin and ...

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

open access: yesAdvanced Science, EarlyView.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

β-catenin expression in perilesional area of different grades of oral squamous cell carcinoma [PDF]

open access: yes, 2016
Objectives: Background: Multistep carcinogenesis discusses a stepwise accumulation of alterations, both genotypic and phenotypic. Arresting one or several of the steps may disturb or delay the development of cancer.

Epithelial TRIM27 Inhibits Intestinal Inflammation in Ulcerative Colitis by the USP7/TRIM27‐IKK Double Negative‐Feedback

open access: yesAdvanced Science, EarlyView.
ABSTRACT The E3 ubiquitin ligase tripartite motif 27 (TRIM27) is a negative regulator of NF‐κB activation and the innate immune response, and TRIM27 deficiency significantly impairs dextran sulfate sodium (DSS)‐induced colitis. The function of TRIM27 in intestinal epithelial cells (IECs), the mechanism by which TRIM27 inhibits the NF‐κB pathway and its

The role of the transcription factor Sox9 for thymic epithelial cell differentation and function [PDF]

open access: yes, 2011
The thymus provides throughout life the specialized stromal microenvironment required for the lifelong generation of naïve T cells. This vital function is dependent on the regular composition and organization of its microenvironment, where specialized ...

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,
