Disrupting Y-Box-Binding Protein 1 Function Using OSU-03012 Prevents Endometriosis Progression in In Vitro and In Vivo Models

The objective of the present study was to test the ability of OSU-03012 (2-amino-N-[4-[5-phenanthren-2-yl-3-(trifluoromethyl)pyrazol-1-yl]phenyl]acetamide), a novel and potent celecoxib-derivative, to impair endometriosis progression in in vitro and in viv ...

A benthic foraminifera species respond to anoxia with a strong metabolic shift suggesting a state of dormancy

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Low-oxygenation events are more and more frequent and strong on continental shelves and in coastal areas where renewal of bottom waters is slow. Among the meiofauna living in such environments, foraminifera are among the most tolerant to the lack of oxygen ...

Biomechanical forces promote blood development through prostaglandin E2 and the cAMP-PKA signaling axis

Olaia Maria Naveiras Torres-Quiroga, Nan Li

Blood flow promotes emergence of definitive hematopoietic stem cells (HSCs) in the developing embryo, yet the signals generated by hemodynamic forces that influence hematopoietic potential remain poorly defined. Here we show that fluid shear stress endows ...

The Molecular Mechanism of the Catalase-like Activity in Horseradish Peroxidase

Ursula Röthlisberger, Pablo Campomanes Ramos

Horseradish peroxidase (HRP) is one of the most relevant peroxidase enzymes, used extensively in immunochemistry and biocatalysis applications. Unlike the closely related catalase enzymes, it exhibits a low activity to disproportionate hydrogen peroxide (H ...

Inflammatory lymphangiogenesis in postpartum breast tissue remodeling

Melody Swartz

Like many cancers, mammary carcinomas use lymphatic vessels to disseminate, and numerous clinical and experimental studies have documented a strong correlation between peritumoral lymphangiogenesis and tumor dissemination. At the same time, many other fact ...

Identification of MAGI1 as a tumor-suppressor protein induced by cyclooxygenase-2 inhibitors in colorectal cancer cells

Cyclooxyganase-2 (COX-2), a rate-limiting enzyme in the prostaglandin synthesis pathway, is overexpressed in many cancers and contributes to cancer progression through tumor cell-autonomous and paracrine effects. Regular use of non-steroidal anti-inflammat ...

β-catenin negatively regulates expression of the prostaglandin transporter PGT in the normal intestinal epithelium and colorectal tumour cells: a role in the chemopreventive efficacy of aspirin?

Paloma Ordonez Moran

BACKGROUND: Levels of the pro-tumorigenic prostaglandin PGE(2) are increased in colorectal cancer, previously attributed to increased synthesis through COX-2 upregulation and, more recently, to decreased catabolism. The functionally linked genes 15-prostag ...

Fetal cells for intervertebral disc regeneration

Aurélie Quintin

Degeneration of the intervertebral disc (IVD) is thought to be one main factor in the development of back pain. It is not a symptom by itself but can lead to painful pathological conditions. Current treatments aim at relieving pain by conservative care, me ...

Modeling the Adsorption and Coagulation of Fulvic Acids on Colloids by Brownian Dynamics Simulations

Marianne Seijo, Montserrat Filella, Serge Stoll

Humic substances (HS) play an important role in the reactivity and transport of colloids in natural environments. In particular, the presence of fulvic acids (FA) in natural waters modifies the interactions between inorg. particles and biopolymers and make ...

Inhibition of the expression and activity of cyclooxygenase-2 by chicory extract

Elodie Debefve

Chicory is a major source of fructans with reported prebiotic-bifidogenic properties. In the present study, the potential anti-inflammatory activities of chicory were investigated. Ethyl acetate chicory root extract produced a marked inhibition of prostagl ...
