Type II restriction modification system in Ureaplasma parvum OMC-P162 strain. [PDF]

PLoS ONE, 2018
Ureaplasma parvum serovar 3 strain, OMC-P162, was isolated from the human placenta of a preterm delivery at 26 weeks' gestation. In this study, we sequenced the complete genome of OMC-P162 and compared it with other serovar 3 strains isolated from ...

Social context prevents heat hormetic effects against mutagens during fish development

FEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Genotyping and antimicrobial resistance patterns of Klebsiella pneumoniae clinical isolates in Suez Canal University Hospitals [PDF]

Microbes and Infectious Diseases
Background: Health crisis of multi-drug resistant Klebsiella pneumoniae (K. pneumoniae) seems overwhelming. Genotyping for such an important pathogen is a demand to control aggressive Klebsiella infections. Therefore, this study was conducted to identify

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair

FEBS Letters, EarlyView.
miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Activity on non-methylated DNA limits the use of endonuclease MspJI for epigenetic analyses

All Results Journals: Biol, 2018
Cytosine methylation of DNA in mammals has been associated with both physiological and pathological changes in gene-expression. DNA treatment with methylation sensitive and/or dependent restriction enzymes, followed by PCR amplification is a widely used ...

Spot‐14 and its paralog Spot‐14R regulate expression of metabolic and thermogenic pathway genes in murine brown and beige adipocytes

FEBS Letters, EarlyView.
Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

A cellular system to study responses to a collision between the transcription complex and a protein‐bound nick in the DNA template

FEBS Letters, EarlyView.
We present the cellular transcription‐coupled Flp‐nick system allowing the introduction of a Top1‐mimicking cleavage complex (Flpcc) at a Flp recognition target site within a controllable LacZ gene. LacZ transcription leads to the collision of RNA polymerase II (RNAPII) with Flpcc, and this causes RNAPII stalling, ubiquitination, and degradation.

Generating site saturation mutagenesis libraries and transferring them to broad host range plasmids using type IIS restriction enzymes [PDF]

arXiv, 2023
Protein engineering is an established method for tailoring enzymatic reactivity. A commonly used method is directed evolution, where the mutagenesis and natural selection process is mimicked and accelerated in the laboratory. Here, we describe a reliable method for generating saturation mutagenesis libraries by golden gate cloning in a broad host range

Ion channel function of polycystin‐2/polycystin‐1 heteromer revealed by structure‐guided mutagenesis

FEBS Letters, EarlyView.
Mutations in polycystin‐1 (PC1) or polycystin‐2 (PC2) cause autosomal‐dominant polycystic kidney disease (ADPKD). We generated a novel gain‐of‐function PC2/PC1 heteromeric ion channel by mutating pore‐blocking residues. Moreover, we demonstrated that PC2 will preferentially assemble with PC1 to form heteromeric complexes when PC1 is co‐expressed ...
