Polyamine Metabolism in Potassium-Deficient Bacteria [PDF]

Journal of Bacteriology, 1972
The metabolism of polyamines was studied in K + -dependent strains of Escherichia coli . When these stringent organisms were in a medium containing Na + instead of K + , protein synthesis was arrested, but synthesis of ribonucleic acid continued

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

iMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Spermine synthesis inhibitor blocks 25-hydroxycholesterol-induced- apoptosis via SREBP2 upregulation in DLD-1 cell spheroids

Biochemistry and Biophysics Reports, 2020
The oxysterol 25-hydroxycholesterol (25-HC) has diverse physiological activities, including the ability to inhibit anchorage-independent growth of colorectal cancer cells. Here, we found that a polyamine synthesis inhibitor, DFMO, prevented 25-HC-induced
