Site-Specific Methylation of Adenine in the Nuclear Genome of a Eucaryote, \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1986
DNA in the polyploid macronucleus of the ciliated protozoan Tetrahymena thermophila contains the modified base N6-methyladenine. We identified two GATC sites which are methylated in most or all of the 45 copies of the macronuclear genome.

Microcalorimetric study on the toxic effect of Pb2+ to Tetrahymena [PDF]

open access: yes, 2007
The toxic effect of Pb2+ has been studied in eukaryotic cells by using Tetrahymena as a target. The maximum power (P (m)) and the growth rate constant (k) were determined, which showed that values of P (m) and k were linked to the concentration (C) of ...

Unveiling the Anticancer Potential of Formylbenzyl‐N,N‐Dimethylmethanaminium‐Based Ionic Liquids via Cheminformatics Approaches

open access: yesJournal of Chemistry, Volume 2025, Issue 1, 2025.
Inhibiting tubulin polymerisation, an essential step for cell proliferation, can control cell division. Our in silico study aims to screen out the derivatives of 1,3‐benzodioxole‐tagged formylbenzyl‐N, N‐dimethylmethanaminium ionic liquid for their potential as anticancer agents.

A Novel Family of Mobile Genetic Elements Is Limited to the Germline Genome in \u3cem\u3eTetrahymena Thermophila\u3c/em\u3e [PDF]

open access: yes, 2002
In the ciliated protozoan Tetrahymena thermophila, extensive DNA elimination is associated with differentiation of the somatic macronucleus from the germline micronucleus.

Acute Toxicities of Bromophenols to Alga and Daphina: Comparative Species Sensitivity Distribution Between Standard and Dietary Supplementation Tests

open access: yesJournal of Toxicology, Volume 2025, Issue 1, 2025.
Bromophenols are synthesized chemicals that are widely used in various industrial activities and are also naturally produced by marine algae as secondary metabolites, including 2,4‐dibromophenol (2,4‐DBP), 2,6‐dibromophenol (2,6‐DBP), and 2,4,6‐tribromophenol (2,4,6‐TBP).

Toxic and genotoxic potential evaluation of soil samples by bioassays

open access: yesActa Agriculturae Slovenica, 2005
Soil samples were obtained from Slovenian industrial region Šaleška dolina and aqueous leachates were prepared. The toxicity and genotoxicity potential of these aqueous fractions have been evaluated by in vitro toxicity and genotoxicity bioassays ...

A Family of Developmentally Excised DNA Elements in \u3cem\u3eTetrahymena\u3c/em\u3e is under Selective Pressure to Maintain an Open Reading Frame Encoding an Integrase-Like Protein [PDF]

open access: yes, 2000
Tlr1 is a member of a family of ~20-30 DNA elements that undergo developmentally regulated excision during formation of the macronucleus in the ciliated protozoan Tetrahymena.

Directional instability of microtubule transport in the presence of kinesin and dynein, two opposite polarity motor proteins. [PDF]

open access: yes, 1992
Kinesin and dynein are motor proteins that move in opposite directions along microtubules. In this study, we examine the consequences of having kinesin and dynein (ciliary outer arm or cytoplasmic) bound to glass surfaces interacting with the same ...

Ecosystem Size Mediates the Effects of Resource Flows on Species Diversity and Ecosystem Function at Different Scales

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
Ecosystem size and resource flows are key factors driving biodiversity and ecosystem function. However, the question of whether and how these drivers interact has been largely overlooked. Here, we show how ecosystem size asymmetry affects biodiversity and function of two‐patch meta‐ecosystems connected through flows of nonliving resources using a ...
