A mitochondria-specific mutational signature of aging: increased rate of A > G substitutions on the heavy strand

Jacques Fellay, Konstantin Popadin, Dmitrii Iliushchenko, Stepan Denisov

The mutational spectrum of the mitochondrial DNA (mtDNA) does not resemble any of the known mutational signatures of the nuclear genome and variation in mtDNA mutational spectra between different organisms is still incomprehensible. Since mitochondria are ...

Hyperpolarized C-13-glucose magnetic resonance highlights reduced aerobic glycolysis in vivo in infiltrative glioblastoma

Rolf Gruetter, Cristina Ramona Cudalbu, Bernard Lanz, Mor-Miri Mishkovsky, Jocelyne Bloch, Arnaud Comment

Glioblastoma (GBM) is the most aggressive brain tumor type in adults. GBM is heterogeneous, with a compact core lesion surrounded by an invasive tumor front. This front is highly relevant for tumor recurrence but is generally non-detectable using standard ...

The influence of the crowding assumptions in biofilm simulations

Vassily Hatzimanikatis, Liliana Angeles Martinez

Author summary In nature, many organisms grow in crowded biofilms that protect against stressful conditions, making their control/eradication a challenge. Modeling these microbial systems is a valuable tool for studying the interactions among cells and exp ...

Comparative RNA-Seq analyses ofDrosophilaplasmatocytes reveal gene specific signatures in response to clean injury and septic injury

Bruno Lemaitre, Jan Paul Dudzic, Elodie Julie Virginie Ramond

Drosophila melanogaster's blood cells (hemocytes) play essential roles in wound healing and are involved in clearing microbial infections. Here, we report the transcriptional changes of larval plasmatocytes after clean injury or infection with the Gram-neg ...
