Nitrogen metabolism in sheep [PDF]

open access: yesBritish Journal of Nutrition, 1971
1.15NH4Cl was continuously infused for periods of 120–216 h into the rumens of sheep which were allowed to feed 2 out of every 10min. These treatments achieved steady metabolic states and allowed the assessment of nitrogen conversions by means of tracer methodology. The sheep were given either a barley diet or one of three hay diets. In two trials, the

Characterising the role of GABA and its metabolism in the wheat pathogen Stagonospora nodorum [PDF]

open access: yes, 2015
A reverse genetics approach was used to investigate the role of γ-aminobutyric acid metabolism in the wheat pathogenic fungus Stagonospora nodorum. The creation of mutants lacking Sdh1, the gene encoding succinic semialdehyde dehydrogenase, resulted in ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Biochanin A improves nitrogen utilization efficiency by regulating ruminal microbial community in dairy goats

open access: yesMicrobiome
Background Rumen microbial nitrogen metabolism is crucial for animal health, productivity, and environmental sustainability in ruminants. Natural products like biochanin A are garnering interest as potential feed additives due to their beneficial effects

Unravelling collembolan life belowground: Stoichiometry, metabolism and release of carbon and nitrogen [PDF]

open access: yes, 2007
This thesis investigated carbon and nitrogen dynamics of soil dwelling Collembola by using direct measurements and stable isotope additions. In an isotope change experiment, collembolans exchanged between 6 and 10% of carbon and nitrogen in their body ...

Regulation of Arabidopsis 14-3-3 gene expression by GABA. [PDF]

open access: yes, 2006
The function in plants of the non-protein amino acid, gamma-aminobutyric acid (GABA) is poorly understood. In this study, we show that GABA down-regulates the expression of a large sub-set of 14-3-3 gene family members in Arabidopsis thaliana seedlings ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Influence of cultivation practices on the metabolism of cytokinin and its correlation in rice production

open access: yesFood and Energy Security, 2023
Cytokinin (CTK) has an important regulatory effect on plant morphology, physiology, and yield, and is one of the main factors regulating nitrogen absorption, transport, and metabolism.

Nitro-fatty acid formation and metabolism [PDF]

open access: yes, 2018
Nitro-fatty acids (NO 2 -FA) are pleiotropic modulators of redox signaling pathways. Their effects on inflammatory signaling have been studied in great detail in cell, animal and clinical models primarily using exogenously administered nitro-oleic acid ...

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

open access: yesFEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐
