Tissue‐Specific Effects of Dietary Protein on Cellular Senescence Are Mediated by Branched‐Chain Amino Acids

Aging Cell, EarlyView.
Restriction of dietary BCAAs protects male mice from the metabolic consequences of both normal‐ and high‐protein diets. BCAA restriction also protects from hepatic cellular senescence in vivo and in vitro, especially in the context of mitochondrial stress. ABSTRACT Dietary protein is a key regulator of healthy aging in both mice and humans.

Disentangling strictly self-serving mutations from win-win mutations in a mutualistic microbial community

eLife, 2019
Mutualisms can be promoted by pleiotropic win-win mutations which directly benefit self (self-serving) and partner (partner-serving). Intuitively, partner-serving phenotype could be quantified as an individual’s benefit supply rate to partners.

Herpes simplex virus‐1 infection alters microtubule‐associated protein Tau splicing and promotes Tau pathology in neural models of Alzheimer's disease

Brain Pathology, EarlyView.
HSV‐1 infection alters MAPT splicing and promotes Tau pathology in neural models of Alzheimer's disease. HSV‐1 infection in brain organoids and neuronal models increase 4R‐MAPT splicing and Tau hyperphosphorylation. HSV‐1 ICP27 is both necessary and sufficient for inducing these changes highlighting the potential role of HSV‐1 in Alzheimer's disease ...

Klebsiella pneumoniae contributes to altered cytotoxicity of thiopurines in vitro: Possible implications of biotransformation and bacterial metabolism

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose Thiopurines are used in paediatric inflammatory bowel disease (IBD), but some patients do not respond. Because the gut microbiota influences drug efficacy and IBD‐patient microbiota presents increased bacterial abundance, we investigated the impact of candidate Enterobacteriaceae on drug cytotoxicity, metabolism and ...

Application of Liquid Chromatography Coupled to Mass Spectrometry for Direct Estimation of the Total Levels of Adenosine and Its Catabolites in Human Blood

Pharmaceuticals
Adenosine is a multifunctional nucleoside with several roles across various levels in organisms. Beyond its intracellular involvement in cellular metabolism, extracellular adenosine potently influences both physiological and pathological processes.

Metabolism of hypoxanthine in wheat shoots

Acta Societatis Botanicorum Poloniae, 2015
The incorporation of [¹⁴C] glycine and [8-^l4C] hypoxanthine to some purine derivatives in overground parts of wheat seedlings was studied. It was found that adenylic acid could be synthesized from glycine and also from free hypoxanthine and in both processes inosinic acid is an intermediate metabolite.

Rapid, Diagnostic Test for Cardiac Ischemia [PDF]

, 2017
Current methods to detect cardiac ischemia rely on biomarkers such as troponin. Elevated levels of troponin are observed hours after the cardiac event.

Cardioprotective effects of the extracellular chaperone clusterin in acute myocardial infarction

European Journal of Clinical Investigation, EarlyView.
In vivo, CLU−/− mice were more susceptible to acute myocardial infarction than CLU+/+ mice. Moreover, inflammation and histone levels were significantly increased in CLU−/− mice compared to CLU+/+ mice following ischemia/reperfusion. In vitro, CLU protects cardiomyocytes from histone‐ and/or hypoxia‐induced cell death.
