Towards an artificial cell: Development of a system which self-regenerates the protein components of the PURE system in microfluidic reactors

Barbora Lavickova

Thanks to recent advancements in synthetic biology, the dream of creating a synthetic cell has become feasible. However, due to its inherent complexity, one of the fundamental functions of all living systems, i.e., self-replication, remains to be introduce ...

A partially self-regenerating synthetic cell

Sebastian Maerkl, Barbora Lavickova, Nadanai Laohakunakorn

Self-regeneration is a fundamental function of all living systems. Here we demonstrate partial molecular self-regeneration in a synthetic cell. By implementing a minimal transcription-translation system within microfluidic reactors, the system is able to r ...

Isothermal multiple displacement amplification of DNA templates in minimally buffered conditions using phi29 polymerase

Carlotta Guiducci, Enrico Tenaglia

The isothermal amplification of DNA in minimally buffered conditions allows to perform and monitor nucleic acid amplification with minimal technological and operative requirements. We show in this work how phi29 can operate multiple displacement amplificat ...

Extraction of cell-free DNA from urine, using polylysine-coated silica particles

Paul Refinetti

DNA analysis is used for a variety of purposes, including disease diagnosis and DNA profiling; this involves extracting DNA from living organisms. In this study, we prepared polycationic silica particles to extract DNA that has the negatively charged phosp ...

Cooperative motion of a key positively charged residue and metal ions for DNA replication catalyzed by human DNA Polymerase-eta

Matteo Dal Peraro

Trans-lesion synthesis polymerases, like DNA Polymerase-eta (Pol-eta), are essential for cell survival. Pol-eta bypasses ultraviolet-induced DNA damages via a two-metal-ion mechanism that assures DNA strand elongation, with formation of the leaving group p ...

On the statistical physics of chains and rods, with application to multi-scale sequence-dependent DNA modelling

Alexandre Emmanuel Grandchamp

The complex mechanisms involved in cellular processes have been increasingly understood this past century and the central role of the DNA molecule has been recognized. The base pair sequence along a DNA fragment is observed not only to encode the genomic i ...

Upstream Binding of Idling RNA Polymerase Modulates Transcription Initiation from a Nearby Promoter

Giovanni Dietler, Aleksandre Japaridze

The bacterial gene regulatory regions often demonstrate distinctly organized arrays of RNA polymerase binding sites of illdefined function. Previously we observed a module of closely spaced polymerase binding sites upstream of the canonical promoter of the ...

CST for the grand finale of telomere replication

Joachim Lingner, Liuh-Yow Chen

Telomeric DNA at eukaryotic chromosome ends terminates with single stranded 3' G-rich overhangs. The overhang is generated by the interplay of several dynamic processes including semiconservative DNA replication, 3' end elongation by telomerase, C-strand f ...

Molecular basis of telomere syndrome caused by CTC1 mutations

Joachim Lingner, Liuh-Yow Chen, Jana Majerská

Mutations in CTC1 lead to the telomere syndromes Coats Plus and dyskeratosis congenita (DC), but the molecular mechanisms involved remain unknown. CTC1 forms with STN1 and TEN1 a trimeric complex termed CST, which binds ssDNA, promotes telomere DNA synthes ...

Cooperative kinking at distant sites in mechanically stressed DNA

Julien Dorier, Davide Demurtas, Guillaume Witz

In cells, DNA is routinely subjected to significant levels of bending and twisting. In some cases, such as under physiological levels of supercoiling, DNA can be so highly strained, that it transitions into non-canonical structural conformations that are c ...

How adeno-associated virus Rep78 relocalises Cdc25B to arrest the cell cycle : the multiple interactions of Rep78 with cellular regulatory, replication and recombination proteins

Adeno-associated virus (AAV) is a small DNA virus belonging to the family of the parvoviridae. AAV infects the human population, however no disease has been associated with this virus. On the contrary, AAV was reported to have oncosuppressive activities. T ...

Interdigitated electrode DNA biosensor for detection of food-borne pathogens by impedance spectroscopy

Daniel Berdat

The commercial application of biosensors has had a significant impact in a number of areas, particularly in the field of medical diagnostics. But in spite of the great number of publications, only a few systems are commercially available in food analysis. ...

BTA, a novel reagent for DNA attachment on glass and efficient generation of solid-phase amplified DNA colonies

Gerardo Turcatti

The tricarboxylate reagent benzene-1,3,5-triacetic acid (BTA) was used to attach 5'-aminated DNA primers and templates on an aminosilanized glass surface for subsequent generation of DNA colonies by in situ solid-phase amplification. We have characterized ...
