Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Tuning the Topology of a Two-Dimensional Catenated DNA Network [PDF]
arXiv, 2022 Molecular topology of polymers plays a key role in determining their physical properties. We studied herein the topological effects on the static and dynamic properties of a 2D catenated network of DNA rings called a kinetoplast. Restriction enzymes, that cleave DNA at sequence-specific sites, are used to selectively cut and remove rings from the ...

Nucleic Acids Research, 1990 DNA methylation at specific sites is most frequently studied by use of methylation-sensitive restriction endonucleases and Southern blotting. We report here that the sensitivity of this method can be increased several-hundred-fold by applying a ligation ...

FEBS Letters, EarlyView.Hermansky‐Pudlak syndrome type 1 (HPS‐1) is a rare, autosomal recessive disorder with poorly understood renal involvement. Urinary extracellular vesicle (uEV) proteomics and a novel Hps1 mouse model reveal mitochondrial abnormalities and lipid accumulation in HPS‐1 kidney proximal tubule cells. Serum ApoA1 correlates with kidney function in our patient

Single-Molecule Morphology of Topologically Digested Olympic Networks [PDF]
arXiv, 2023 The kinetoplast DNA (kDNA) is the archetype of a two-dimensional Olympic network, composed of thousands of DNA minicircles and found in the mitochondrion of certain parasites. The evolution, replication and self-assembly of this structure are fascinating open questions in biology that can also inform us how to realise synthetic Olympic networks in ...

Is the Kinetoplast DNA a Percolating Network of Linked Rings at its Critical Point? [PDF]
Phys. Biol. 12 (2015) 036001, 2014 In this work we present a computational study of the Kinetoplast genome, modelled as a large number of semiflexible unknotted loops, which are allowed to link with each other. As the DNA density increases, the systems shows a percolation transition between a gas of unlinked rings and a network of linked loops which spans the whole system.

Consecutive Cycles of Precise, Unidirectional 14-bp Deletions Using a BseRI/BsgI Trimming Plasmid
BioTechniques, 1996 A straightforward method for generating precise, consecutive, unidirectional 14-bp deletions into cloned DNA, adopted from the trimming principle developed by Szybalski and his colleagues, is presented. The method utilizes pTRIM14, a plasm id constructed

Cleavage of DNA.RNA hybrids by type II restriction enzymes
Nucleic Acids Res., 1980 The action of a number of restriction enzymes on DNA.RNA hybrids has been examined using hybrids synthesised with RNAs of cucumber mosaic virus as templates. The enzymes EcoRI, HindII, SalI, MspI, HhaI, AluI, TaqI and HaeIII cleaved the DNA strand of the

DNA Cloning without Restriction Enzyme and Ligase
BioTechniques, 1999 One common problem in using the traditional DNA cloning procedure is that suitable natural restriction sites are often unavailable for a given task. Creating new restriction sites is often time consuming. Here, I describe a simple technique of producing "customized cohesive ends" by a combination of PCR primer design and lambda exonuclease digestion ...

FEBS Letters, EarlyView.The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.
