CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Cartier-Dieudonné theory for Chow groups.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1985
Let k be a perfect field of positive characteristic, X a smooth projective variety over k and \({\mathcal C}\) the category of augmented artinian local k-algebras. For \(A\in {\mathcal C}\) let \({\mathcal K}^ s_{n,X\times A/X}\) be the sub-sheaf of the sheaf of Quillen's K-groups on \(X\times_{spec k}spec A\) which is locally generated by Steinberg ...

Stable maps and Chow groups

open access: yesDocumenta Mathematica, 2013
According to the Bloch–Beilinson conjectures, an automorphism of a K3 surface X that acts as the identity on the transcendental lattice should act trivially on \operatorname{CH}^2(X)

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

open access: yesFEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

The Effects of Bitter Kola Supplemented Diet on Hepatotoxicity of Mercury in Wistar Rats

open access: yesJournal of Applied Sciences and Environmental Management, 2010
The effect of bitter kola on the hepatotoxicity following mercury poisoning (mercuric chloride solution of 10ppm) was investigated in rats for a duration of six weeks. Thirty (30) acclimatized Wistar rats were divided into five groups(n=6).Group I served

Characterization of Different Commercial Dietary Supplements in the Peri-Weaning Period on Consumption and Growth Performance in C57Bl/6J Mice

open access: yesAnimals, 2020
This experiment was conducted to investigate the effects of common commercially available dietary supplementation in the peri-weaning period on feed intake, growth, and survival in C57Bl/6J mouse pups and lactating dams. A total of 96 pups and their dams

A resveratrol derivative modulates TRH and TRH‐like peptide expression throughout the brain and peripheral tissues of male rats

open access: yesEndocrinology, Diabetes & Metabolism, 2022
Introduction Resveratrol and related polyphenols have therapeutic effects ranging from treatment of depression, Alzheimer's and Parkinson's disease, obesity, diabetes, neurodegeneration and ageing. TRH and TRH‐like peptides, with the structure pGlu‐X‐Pro‐

Chow-Witt rings of Grassmannians

open access: yes, 2020
We complement our previous computation of the Chow-Witt rings of classifying spaces of special linear groups by an analogous computation for the general linear groups. This case involves discussion of non-trivial dualities. The computation proceeds along

Inhibitory effect of the melanocortin receptor agonist melanotan-II (MTII) on feeding depends on dietary fat content and not obesity in rats on free-choice diets

open access: yesFrontiers in Behavioral Neuroscience, 2015
Introduction: Conflicting data exist on sensitivity changes of the melanocortin system during diet-induced obesity. We hypothesized that melanocortin sensitivity depends on diet composition, in particular on the fat content rather than the level of ...
