Engineering the Regenerative Microenvironment with Biomaterials

Jeffrey Alan Hubbell, Mikaël Martino, Priscilla Suhasna Maithili Briquez, Federico Tortelli, Jeffrey James Rice

Modern synthetic biomaterials are being designed to integrate bioactive ligands within hydrogel scaffolds for cells to respond and assimilate within the matrix. These advanced biomaterials are only beginning to be used to simulate the complex spatio-tempor ...

Insights into Intrastrand Cross-Link Lesions of DNA from QM/MM Molecular Dynamics Simulations

Ursula Röthlisberger, Chandan Patel

DNA damages induced by oxidative intrastrand cross-links have been the subject of intense research during the past decade. Yet, the currently available experimental protocols used to isolate such lesions only allow to get structural information about linke ...

Infection-induced host translational blockage inhibits immune responses and epithelial renewal in the Drosophila gut

Bruno Lemaitre, Sveta Chakrabarti

Typically, immune responses control the pathogen, while repair and stress pathways limit damage caused by pathogenesis. The relative contribution of damage to the outcome of pathogenesis and the mechanistic links between the immune and repair pathways are ...

Directed evolution of the suicide protein O⁶-alkylguanine-DNA alkyltransferase for increased reactivity results in an alkylated protein with exceptional stability

Ursula Röthlisberger, Kai Johnsson, Florence Pojer, Elizabeth Claire Brunk, Birgit Mollwitz, Simone Schmitt

Here we present a biophysical, structural, and computational analysis of the directed evolution of the human DNA repair protein O-6-alkylguanine-DNA alkyltransferase (hAGT) into SNAP-tag, a self-labeling protein tag. Evolution of hAGT led not only to incre ...

Telomeric Repeat Containing RNAs and the Response to Telomere Deprotection in Saccharomyces Cerevisiae

Andrea Bernardo Panza

Telomeres are the DNA/RNA/protein structures at the end of linear eukaryotic chromosomes, which protect them against the DNA damage repair machinery, preventing chromosome end-to-end fusions and aberrant recombination. Moreover, telomeres compensate for th ...

Cytotoxic gold compounds: synthesis, biological characterization and investigation of their inhibition properties of the zinc finger protein PARP-1

Michael Graetzel, Shaik Mohammed Zakeeruddin, Rosario Scopelliti, Angela Casini, Fabio Edafe, Maria Serratrice

The new gold(III) complexes: [Au{2-(2'-pyridyl) imidazolate}Cl-2] and [Au{2,6-bis(2'-benzimidazolate) pyridine}(OCOCH3)] and the mono-and binuclear gold(I) complexes: Au{2-(2'-pyridyl) imidazole} (PPh3), [Au(2-phenylimidazolate)(DAPTA)] (DAPTA = 3,7 ...

The ATM substrate KAP1 controls DNA repair in heterochromatin: Regulation by HP1 proteins and Serine 473/824 phosphorylation

Didier Trono, Andrea Corsinotti

The repair of DNA damage in highly compact, transcriptionally silent heterochromatin requires that repair and chromatin packaging machineries be tightly coupled and regulated. KAP1 is a heterochromatin protein and co-repressor which binds to HP1 during gen ...

A Point Mutation in cycA Partially Contributes to the D-cycloserine Resistance Trait of Mycobacterium bovis BCG Vaccine Strains

Stewart Cole, Swapna Uplekar, Jeffrey Chen

In mycobacteria, CycA a D-serine, L-and D-alanine, and glycine transporter also functions in the uptake of D-cycloserine, an important second-line anti-tubercular drug. A single nucleotide polymorphism identified in the cycA gene of BCG was hypothesized to ...

Interference between PARPs and SIRT1: a novel approach to healthy ageing?

Johan Auwerx, Carlos Canto Alvarez

Poly(ADP-ribosyl) polymerases (PARPs) have traditionally been linked to chromosome maintenance and DNA repair. Recent findings identify PARPs as key modulators of metabolism through their influence on SIRT1 activity, hinting to a possible role of PARPs as ...

Rad51 paralogues Rad55-Rad57 balance the antirecombinase Srs2 in Rad51 filament formation

Henning Paul-Julius Stahlberg, Jie Liu

Homologous recombination is a high-fidelity DNA repair pathway. Besides a critical role in accurate chromosome segregation during meiosis, recombination functions in DNA repair and in the recovery of stalled or broken replication forks to ensure genomic st ...
