Detection and Diversity evaluation of tetracycline resistance genes in grassland-based production systems in Colombia, South America [PDF]

Frontiers in Microbiology, 2011
Grassland-based production systems use approximately 26 percent of land surface on earth. However, there are no evaluations of these systems as a source of antibiotic pollution.

The chromatin remodelling protein LSH/HELLS regulates the amount and distribution of DNA hydroxymethylation in the genome

Epigenetics, 2022
Ten-Eleven Translocation (TET) proteins convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) leading to a dynamic epigenetic state of DNA that can influence transcription and chromatin organization.

Chlamydia suis displays high transformation capacity with complete cloning vector integration into the chromosomal rrn-nqrF plasticity zone

Microbiology Spectrum, 2023
Chlamydia, comprising several human and zoonotic pathogens, is a genus of the conserved bacterial phylum Chlamydiota. Their obligate intracellular niche serves as a barrier for natural genetic exchange via horizontal gene transfer (HGT), and further ...

Advances in mechanism study on novel tetracycline-inactivating enzymes tet(X) causing emerging tigecycline resistance [PDF]

Zhenduanxue lilun yu shijian, 2023
Antibiotic resistance in bacteria has become a great threat to global public health. Tigecycline is a next-generation tetracycline that is the final line of defense against severe infections by carbapenem-resistant Gram-negative bacteria.

Source Tracking and Global Distribution of the Tigecycline Non-Susceptible tet(X)

Microbiology Spectrum, 2021
The emergence of tet(X) genes has compromised the clinical use of the last-line antibiotic tigecycline. We identified 322 (1.21%) tet(X) positive samples from 12,829 human microbiome samples distributed in four continents (Asia, Europe, North America ...

TET family regulates the embryonic pluripotency of porcine preimplantation embryos by maintaining the DNA methylation level of NANOG

Epigenetics, 2020
The ten-eleven translocation (TET) family (TET1/2/3) initiates conversion of 5-methylcytosine to 5-hydroxymethylcytosine, thereby orchestrating the DNA demethylation process and changes in epigenetic marks during early embryogenesis.

Vitamin C in combination with inhibition of mutant IDH1 synergistically activates TET enzymes and epigenetically modulates gene silencing in colon cancer cells

Epigenetics, 2020
Mutations in the enzyme isocitrate dehydrogenase 1 (IDH1) lead to metabolic alterations and a sustained formation of 2-hydroxyglutarate (2-HG). 2-HG is an oncometabolite as it inhibits the activity of α-ketoglutarate-dependent dioxygenases such as ten ...
