Novel Fmoc-Polyamino Acids for Solid-Phase Synthesis of Defined Polyamidoamines [PDF]

open access: yes, 2011
A versatile solid-phase approach to sequence-defined polyamidoamines was developed. Four different Fmoc-polyamino acid building blocks were synthesized by selective protection of symmetrical oligoethylenimine precursors followed by introduction of a ...

Polyamines Upregulate Cephalosporin C Production and Expression of β-Lactam Biosynthetic Genes in High-Yielding Acremonium chrysogenum Strain

open access: yesMolecules, 2021
The high-yielding production of pharmaceutically significant secondary metabolites in filamentous fungi is obtained by random mutagenesis; such changes may be associated with shifts in the metabolism of polyamines.

Ornithine decarboxylase activity, a clinical biomarker for evaluating cancer chemopreventive efficacy of phytomolecules [PDF]

open access: yes, 2011
Biomarkers of cancer have made a strong traipse in predicting the disease pattern and contributed significantly to the understanding of tumour state, progression, characteristics and response to therapies.

Urinary Excretion of Free and Acetylated Polyamines in Hepatocellular Carcinoma

open access: yesThe International Journal of Biological Markers, 1998
Polyamines (putrescine, spermidine and spermine) are essential for the proliferation of normal and neoplastic cells, and have been repeatedly recommended as tumor markers, with contrasting and elusive results.

Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]

open access: yes, 2013
Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Optimization of ClpXP activity and protein synthesis in an E. coli extract-based cell-free expression system. [PDF]

open access: yes, 2018
Protein degradation is a fundamental process in all living cells and is essential to remove both damaged proteins and intact proteins that are no longer needed by the cell.

Polyamines control of cation transport across plant membranes: implications for ion homeostasis and abiotic stress signaling

open access: yesFrontiers in Plant Science, 2014
Polyamines are unique polycationic metabolites, controlling a variety of vital functions in plants, including growth and stress responses. Over the last two decades a bulk of data was accumulated providing explicit evidence that polyamines play an ...

Metabolomic analysis of cricket paralysis virus infection in Drosophila S2 cells reveals divergent effects on central carbon metabolism as compared with silkworm Bm5 cells [PDF]

open access: yes, 2020
High-throughput approaches have opened new opportunities for understanding biological processes such as persistent virus infections, which are widespread.

Intestinal gene expression in pigs: effects of reduced feed intake during weaning and potential impact of dietary components [PDF]

open access: yes, 2011
The weaning transition is characterised by morphological, histological and microbial changes, often leading to weaning-associated disorders. These intestinal changes can partly be ascribed to the lack of luminal nutrition arising from the reduced feed ...
