Endothelial Pim3 kinase protects the vascular barrier during lung metastasis

Nature Communications
Endothelial cells (ECs) form a tissue-specific barrier for disseminating cancer cells in distant organs. However, the molecular regulation of the ECs in the metastatic niche remains unclear.

Nicotinamide and Pyridoxine Supplementation Enhances Muscle Stem Cell Activity and Muscle Regeneration in Humans: A Randomized Placebo‐Controlled Clinical Trial of High Force Eccentric Contraction Recovery in Healthy Young Men

Advanced Science, EarlyView.
In a randomized clinical trial, we test the potential of combined nicotinamide (NAM) and pyridoxine (PN) to improve muscle recovery through muscle stem cell (MuSC) activity. Daily oral NAM and PN supplementation after high intensity muscle contractions enhances MuSC activation and differentiation, and accelerates muscle regeneration, providing new ...

Targeted H2S Delivery System Attenuates Blood‐Spinal Cord Barrier Disruption after Spinal Cord Injury by Reshaping the Ferritinophagy Pathway

Advanced Science, EarlyView.
The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...

Beta-catenin expression in psoriasis

Indian Dermatology Online Journal, 2015
Background: Psoriasis is a common inflammatory skin disease characterized by abnormal keratinocyte proliferation and differentiation. Beta-catenin participates in intercellular adhesion.

Activation of ERBB4 Pathway Inhibits Pathological Transdifferentiation of Lung Epithelial Progenitors into CD66c+ Basal Cells in Severe Lung Injury

Advanced Science, EarlyView.
In fibrotic distal lung regions, CD66c+ basal cells emerge as a pathological state. Using human distal lung organoids, this study identifies CD66c+ basal cells as a pro‐fibrotic state arising through transdifferentiation from secretory, AT2, and basal cells.

Actin Cytoskeleton Remodeling Accompanied by Redistribution of Adhesion Proteins Drives Migration of Cells in Different EMT States

Cells
Epithelial–mesenchymal transition (EMT) is a process during which epithelial cells lose epithelial characteristics and gain mesenchymal features. Here, we used several cell models to study migratory activity and redistribution of cell–cell adhesion ...

β- catenin Expression and Its Relation to Bryne’s Invasive Grading System in Oral Squamous Cell Carcinoma

Journal of Baghdad College of Dentistry, 2016
Background: Invasion in oral cancer involves alterations in cell-cell and cell-matrix interactions that accompanied by loss of cell adhesion. Catenins stabilize cellular adherence junctions by binding to E-cadherin, which further mediates cell-cell ...

Phosphorylation of β-catenin results in lack of β-catenin signaling in melanoma

International Journal of Oncology, 2011
The Wnt/β-catenin pathway is involved in differentiation events during embryonic development and is further described as a pathway often participating in tumor formation when aberrantly activated. Molecular studies concentrating on colorectal cancer revealed mutations of apc, ctnnbi, btrc and tcf-4 genes which mimic Wnt stimulation.

Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

Advanced Science, EarlyView.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...
