The FOXC2‐LAMA4 Axis Orchestrates Vasculogenic Mimicry and Immunosuppressive Niche Formation to Drive Metastatic Cascade in Renal Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
Advanced clear cell renal cell carcinoma metastasis is driven by a FOXC2+ tumor subpopulation. These cells execute vasculogenic mimicry for dissemination and secrete LAMA4. LAMA4 engages macrophage ITGA6, activating the STAT6/GATA3 axis to polarize macrophages into a pro‐metastatic, immunosuppressive phenotype.

ETV4 Promotes Colorectal Cancer Progression by Reprogramming Asparagine Metabolism to Remodel the Stromal Microenvironment

open access: yesAdvanced Science, EarlyView.
ETV4 coordinates a dual transcriptional program by upregulating MET and asparagine synthetase (ASNS). The resulting asparagine (Asn) secretion acts as a metabolic signal, reprogramming hepatic stellate cells (HSCs) and primary cancer‐associated fibroblasts (CAFs) toward an inflammatory phenotype. These activated stromal cells release HGF to sustain the

No difference in paratuberculosis seroprevalence between organic and conventional dairy herds in the Netherlands [PDF]

open access: yes, 2005
Purpose. Paratuberculosis or Johne’s disease in cattle is considered to play a role in the pathogenesis of Crohn’s disease in humans. Whether organic production may influence the prevalence of paratuberculosis in dairy herds was not known until now and ...

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

open access: yesAdvanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

The transfer of 137Cs through the soil-plant-sheep food chain in different pasture ecosystems

open access: yesAgricultural and Food Science, 2008
A grazing experiment with sheep was carried out in 1990-1993 on natural, semi-natural and cultivated pasture on clay soil. The pastures were located in Southern Finland and were moderately contaminated with 137 Cs by Chernobyl fallout.

Mapping Genetic Regulation of Transcription to Identify Functional Variants and Genes Associated with Pancreatic Cancer Risk

open access: yesAdvanced Science, EarlyView.
Integration of a pancreatic eQTL map with a GWAS meta‐analysis identifies 82 putative functional variants and 15 genes. The association between rs11102484 and pancreatic cancer risk is observed in a total of 5699 cases and 8467 controls. The G allele of rs11102484 weakens ZNF263 binding and the silencer‐promoter interaction, thereby increasing ST7L ...

Dairy farming in Uganda. Production Efficiency and Soil Nutrients under Different Farming Systems [PDF]

open access: yes, 2007
Prior to the 1980s, milk production in Uganda occurred largely in two contrasting production systems. In the wetter parts of the country, especially in the southwest, there were a few large, mostly government-owned commercial dairy farms on which exotic ...

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths

open access: yesAdvanced Science, EarlyView.
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...
