Effectiveness of the enzyme cytosine deaminase in the free living ciliary organism Tetrahymena pyriformis (Ehrenberg, 1830) [PDF]
مجلة التربية والعلم, 2008 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

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

An EPR study on cytosine irradiated
Journal of Physical Organic Chemistry, 2010 AbstractIn this study, paramagnetic centers over the cytosine were formed by photolysis then these centers were investigated using EPR method. EPR signals were not recorded from non‐irradiated the cytosine, but irradiated polycrystalline exhibited complex EPR spectra. For obtaining of cytosine polycrystalline, novel crystallization method was performed

Cytosine-Based TET Enzyme Inhibitors.
ACS Medicinal Chemistry Letters, 2019 DNA methylation is known as the prima donna epigenetic mark for its critical role in regulating local gene transcription. Changes in the landscape of DNA methylation across the genome occur during cellular transition, such as differentiation and altered ...

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Diversity of cytosine methylation across the fungal tree of life
Nature Ecology & Evolution, 2019 The generation of thousands of fungal genomes is leading to a better understanding of genes and genomic organization within the kingdom. However, the epigenome, which includes DNA and chromatin modifications, remains poorly investigated in fungi.
