Deciphering the nature of cell state transitions in single cells using quantitative modeling of temporal dynamics

Alex Russell Lederer

Cells are the smallest operational units of living systems. Through synthesis of various biomolecules and exchange of signals with the environment, cells tightly regulate their composition to realize a specific functional state. The transformation of a cel ...

Genomics of Preaxostyla Flagellates Illuminates the Path Towards the Loss of Mitochondria

Marek Elias, Shweta Vinodrai Pipaliya

The notion that mitochondria cannot be lost was shattered with the report of an oxymonad Monocercomonoides exilis, the first eukaryote arguably without any mitochondrion. Yet, questions remain about whether this extends beyond the single species and how th ...

Transcriptomic data meta-analysis reveals common and injury model specific gene expression changes in the regenerating zebrafish heart

Marius Alexandru Botos Rogozsan

Zebrafish have the capacity to fully regenerate the heart after an injury, which lies in sharp contrast to the irreversible loss of cardiomyocytes after a myocardial infarction in humans. Transcriptomics analysis has contributed to dissect underlying signa ...

An integrative multi-omics approach reveals new central nervous system pathway alterations in Alzheimer's disease

Christopher Clark

Background Multiple pathophysiological processes have been described in Alzheimer's disease (AD). Their inter-individual variations, complex interrelations, and relevance for clinical manifestation and disease progression remain poorly understood. We hypot ...

Dual proteomics of Drosophila melanogaster hemolymph infected with the heritable endosymbiont Spiroplasma poulsonii

Bruno Lemaitre, Florent François Masson, Samuel Rommelaere, Alice Marra, Fanny Schüpfer

Insects are frequently infected with heritable bacterial endosymbionts. Endosymbionts have a dramatic impact on their host physiology and evolution. Their tissue distribution is variable with some species being housed intracellularly, some extracellularly ...

Cell type prioritization in single-cell data

Grégoire Courtine, Gioele La Manno, Quentin Barraud, Jordan Squair, Claudia Kathe, Matthieu Pierre Gautier, Mark Andrew Anderson, Thomas Haynes Hutson, Michael Alexander Skinnider, Marco Milano

The cell types affected by biological perturbations in complex tissues are uncovered by single-cell analysis. ...

Integrated proteogenomic deep sequencing and analytics accurately identify non-canonical peptides in tumor immunopeptidomes

Didier Trono, George Coukos, Marion Leleu, Evaristo Jose Planet Letschert, Alexandre Harari, Delphine Yvette L Grun, Markus Müller, Florian Huber, Laia Simo Riudalbas

Efforts to precisely identify tumor human leukocyte antigen (HLA) bound peptides capable of mediating T cell-based tumor rejection still face important challenges. Recent studies suggest that non-canonical tumor-specific HLA peptides derived from annotated ...

Optimization methods and objective functions for analysis of metabolic network models

Zhaleh Hosseini

Computational studies of metabolism aim to systematically analyze the metabolic behaviour of biological systems in different conditions. Genome-scale metabolic network models (GEMs) capture the connection between elements of the network by applying stoichi ...

Systems-Genetics-Based Inference of a Core Regulatory Network Underlying White Fat Browning

Bart Deplancke, Julie Marie Russeil, Petra Catalina Schwalie

Recruitment of brite/beige cells, known as browning of white adipose tissue (WAT), is an efficient way to turn an energy-storing organ into an energy-dissipating one and may therefore be of therapeutic value in combating obesity. However, a comprehensive u ...

A Tale of Two Tumors: Unraveling the Complexities of Epigenetic Dysregulation in Cancer

Maria Christine Donaldson

Epigenetics plays an important role in cancer development and progression. Cancer cells hijack the epigenome by modifying the histone protein units responsible for packaging DNA, or by modifying the DNA itself, resulting in changes to chromatin topology an ...

Integrative approach to analyze the proximal region of the Trichonympha agilis centriole

Veronika Nemcíková Villímová

The centrosome, the major microtubule organizing center in animal cells, is composed of two orthogonally arranged centrioles and surrounding pericentriolar material. Centrioles are evolutionary conserved organelles characterized by a nine-fold symmetry of ...

Mitochondrial stress signalling and its impacts on physiology

Adrienne Joëlle Laurence Mottis

Mitochondria are responsible for respiration and energy harvesting across the eukaryotic kingdom. They also take part in other cellular processes like intermediary metabolism. As a result, mitochondrial function directly impacts organismal features such as ...

Evolutionary dynamics of coding and non-coding transcriptomes

Anamaria Necsulea

Gene expression changes may underlie much of phenotypic evolution. The development of high-throughput RNA sequencing protocols has opened the door to unprecedented large-scale and cross-species transcriptome comparisons by allowing accurate and sensitive a ...

The response of Desulfotomaculum reducens MI-1 to U(VI) exposure: a transcriptomic study

Rizlan Bernier-Latmani, Elena Cristina Dalla Vecchia

Desulfotomaculum reducens is the first Gram-positive sulfate- and metal-reducing bacterium for which the transcriptomic response to uranium exposure has been evaluated. The genes upregulated during fermentative growth in the presence of U(VI) as compared t ...

Proteogenomic studies in epithelial ovarian cancer: established knowledge and future needs

Darlene Goldstein

There has been a concerted effort over the last decade to improve our understanding of the complex biology of ovarian cancer. A linear growth in published proteogenomic studies has addressed a variety of questions regarding its molecular pathogenesis. A nu ...
