Histone Chaperone Nrp1 Mutation Affects the Acetylation of H3K56 in Tetrahymena thermophila

open access: yesCells, 2022
Histone modification and nucleosome assembly are mainly regulated by various histone-modifying enzymes and chaperones. The roles of histone-modification enzymes have been well analyzed, but the molecular mechanism of histone chaperones in histone ...

Nucleus-specific linker histones Hho1 and Mlh1 form distinct protein interactions during growth, starvation and development in Tetrahymena thermophila [PDF]

open access: yes, 2019
Chromatin organization influences most aspects of gene expression regulation. The linker histone H1, along with the core histones, is a key component of eukaryotic chromatin.

Comparative pathology boards facilitate the translation of knowledge between canine and human cancer patients

open access: yesBrain Pathology, Volume 35, Issue 5, September 2025.
Comparative pathology boards bring together anatomic pathologists with expertise in canine and human histology to identify shared features, including immune or TME components, tumor subtypes, or prognostic tissue biomarkers. This article summarizes feedback to improve future initiatives and enhance the translational relevance of comparative oncology ...

Monitoring Euplotes species dynamics in mixed experiments using genetic markers for quantitative polymerase chain reaction

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 7, Page 442-450, July 2025.
Abstract Ciliates are widespread and play a major role in ecosystems as they form an important link between primary producers and higher trophic levels. They have been used as a classic model to study predator–prey interactions of co‐evolutionary processes.

Quantitative analysis of nucleolar chromatin distribution in the complex convoluted nucleoli of Didinium nasutum (Ciliophora)

open access: yesBiological Research, 2013
We have earlier shown that the typical Didinium nasutum nucleolus is a complex convoluted branched domain, comprising a dense fibrillar component located at the periphery of the nucleolus and a granular component located in the central part.

How Single Cells Form Shells: Maturation and Secretion of Lorica‐Forming Material in the Tintinnid Schmidingerella (Alveolata, Ciliophora)

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 4, July/August 2025.
ABSTRACT Tintinnid ciliates are distinguished by their loricae (shells), the key synapomorphy of these mainly marine planktonic protists. They can divide daily, with a considerable portion of biomass stored in the loricae. During each division, lorica‐forming material (LFM) is produced and afterwards used by the proter (anterior division product) to ...

An investigation of the nuclei of hülle cells of Aspergillus nidulans

open access: yesGenetics and Molecular Biology, 2002
Certain species of fungi of the genus Aspergillus produce a type of cells around the cleistothecium that are called hülle cells. To facilitate the analysis of the formation of these cells, an Aspergillus nidulans strain with high hülle cell production ...

Morphometric study of a Brazilian strain of Carchesium polypinum (Ciliophora: Peritrichia) attached to Pomacea figulina (Mollusca: Gastropoda), with notes on a high infestation

open access: yesZoologia (Curitiba), 2010
During an ecological study of the epibiotic relationship between ciliate protists and Pomacea figulina (Spix, 1827) (Gastropoda, Ampullariidae), originating from an urban stream in southeast Brazil, a high infestation by the peritrich ciliate Carchesium ...

DNA Synthesis, Methylation and Degradation During Conjugation in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1985
We have investigated the timing of DNA synthesis, methylation and degradation during macronuclear development in the ciliate, Tetrahymena thermophila. DNA synthesis was first detected in the anlagen early in macronuclear development, but the majority of ...
