DNA replication elongation is tightly controlled by histone-modifying enzymes. Our previous studies showed that the histone methytransferase TXR1 (Tetrahymena Trithorax related protein 1) specifically catalyzes H3K27 monomethylation and affects DNA ...

Exploring the Histone Acetylation Cycle in the Protozoan Model Tetrahymena thermophila
The eukaryotic histone acetylation cycle is composed of three classes of proteins, histone acetyltransferases (HATs) that add acetyl groups to lysine amino acids, bromodomain (BRD) containing proteins that are one of the most characterized of several ...

Differential Assembly of Catalytic Interactions within the Conserved Active Sites of Two Ribozymes. [PDF]
Molecular recognition is central to biology and a critical aspect of RNA function. Yet structured RNAs typically lack the preorganization needed for strong binding and precise positioning.

Modeling telomere shortening process
Abstract Cell senescence has attracted much attention in the long history of human beings, and telomere shortening (TS) is one of the main concerns in the study of cell senescence. To reveal the microscopic mechanism of TS process, we model it based on molecular stochastic process from the perspective of nonequilibrium statistical physics. We associate

Germ Line-Specific DNA Sequences are Present on All Five Micronuclear Chromosomes in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]
The development of the macronucleus from the zygotic micronucleus in the ciliated protozoan Tetrahymena spp. involves the elimination of specific DNA sequences (M. C. Yao and M. Gorovsky, Chromosoma 48:1-18 1974).

Effectiveness of the enzyme cytosine deaminase in the free living ciliary organism Tetrahymena pyriformis (Ehrenberg, 1830) [PDF]
Cytosine deaminase (EC.3.5.4.1) activity and properties was determined in the extract of the free living ciliata Tetrahymena pyriformis grown in proteose peptone medium. The optimum conditions for the enzyme activity was also determined and it was found

A Conceptual DFT Approach Towards Developing New QSTR Models [PDF]
Quantitative-structure-toxicity-relationship (QSTR) models are developed for predicting the toxicity (pIGC50) of 252 aliphatic compounds on Tetrahymena pyriformis. The single parameter models with a simple molecular descriptor, the number of atoms in the molecule, provide unbelievable results.

Exploring the Frontiers of Cell Temperature Measurement and Thermogenesis
This review focuses on the mechanisms of local temperature generation within cells and the methods developed for accurate temperature assessment. Contact and noncontact techniques are introduced, including infrared thermography, fluorescence thermometry, and other innovative localized temperature measurement approaches.
