Transcriptional Regulation of Gene Expression in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

, 1990
The only well-characterized study of gene expression in Tetrahymena thermophila (1) demonstrates that the temperature dependent expression of the Ser H3 gene is regulated at the level of mRNA stability.

Metagenomic and biogenic amine changes in cassava fermentation for tucupi production using Pediococcus acidilactici starter culture

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The use of starter cultures is essential for producing fermented foods with desirable standardized characteristics and for preventing pathogens. Pediococcus acidilactici, isolated from cocoa fermentation, was used in the production of tucupi, a widely appreciated sauce made from the juice of cassava root (manipueira) in the ...

Emerging Therapeutic Strategies in Anti‐Aging Medicine: A Comprehensive Review

Medicine Bulletin, EarlyView.
ABSTRACT Aging is orchestrated by interconnected hallmarks such as genomic instability, mitochondrial dysfunction, cellular senescence, and disrupted intercellular communication, which collectively drive chronic disease progression. Recent advances have expanded therapeutic opportunities to include pharmacological agents, gene and epigenome editing ...

Prooxidant-antioxidant balance in the methylotrophic yeast Ogataea polymorpha exoposed to spermidine

Біологічні студії, 2020
Background. Many molecular compounds used by eukaryotic cells as antioxidant agents can directly interact with reactive oxygen/nitrogen species. Among them are polyamines – natural substances with pronounced antioxidant properties.

The Effect of Spermidine on the Rate of Sex-Linked Recessive Lethals Caused by X-Ray in Drosophila Melanogaster [PDF]

, 1984
31 leaves. Advisor: Michael E. MyszewskiThe problem. Spermidine is a polyamine naturally occurring in many organisms including "Drosophila melanogaster". It has been shown to decrease the heat denaturation of DNA by binding to the DNA double helix.

Design and Synthesis of Polyamine‐Proteolysis Targeting Chimera Conjugates for Histone Deacetylase (HDAC) Degradation with Enhanced Cellular Uptake

ChemistryOpen, EarlyView.
In this article, proteolysis targeting chimeras (PROTACs) bearing a polyamine linker capable of crossing cancer cell membranes via the polyamine transport system are synthesized and evaluated. The results provide valuable insights for the design of PROTACs with enhanced cellular uptake efficiency.
