Autorepression of yeast Hsp70 cochaperones by intramolecular interactions involving their J-domains

Paolo De Los Rios, Bruno Claude Daniel Fauvet, Adélaïde Alice Mohr, Mathieu Rebeaud, Satyam Tiwari

The 70 kDa heat shock protein (Hsp70) chaperones control protein homeostasis in all ATP-containing cellular compartments. J-domain proteins (JDPs) coevolved with Hsp70s to trigger ATP hydrolysis and catalytically upload various substrate polypeptides in ne ...

Perfect adaptation achieved by transport limitations governs the inorganic phosphate response in S. cerevisiae

Sebastian Maerkl, Shiyu Cheng, Hon Ming Andrew Yip, Michael Andrew Crone, Evan James Olson

Cells cope with and adapt to ever-changing environmental conditions. Sophisticated regulatory networks allow cells to adjust to these fluctuating environments. One such archetypal system is the Saccharomyces cerevisiae Pho regulon. When external inorganic ...

Modeling, analysis, and design of complex biological networks

Mohammadomid Oftadeh

Automating experimental procedures has resulted in an unprecedented increase in the volume of generated data, which, in turn, has caused an accumulation of unprocessed data. As a result, the need to develop tools to analyze data systematically has been ris ...

High-throughput Microfluidic Platforms for S. cerevisiae Single Cell Studies

Hon Ming Andrew Yip

Cells consume extra-cellular nutrients and resources to maintain cellular fitness. Extra-cellular conditions vary over time. Cellular programs encoded in genes adjust to adapt to the environments. Gene regulatory networks (GRNs) have evolved to be responsi ...

Principles of checkpoint override

Ahmad Sadeghi

Why biological quality-control systems fail is often mysterious. Specifically, checkpoints such as the DNA damage checkpoint or the spindle assembly checkpoint are overriden after prolonged arrests allowing cells to continue dividing despite the continued ...

Metabolic regulation of cytokinesis in Schizosaccharomyces pombe

Özge Uysal Özdemir

All cells need to be able to sense their environment, and adapt their metabolism, growth and cell division appropriately. In this study, I examined the response of Schizosaccharomyces pombe to a change in the carbon source and how that affects cytokinesis. ...

Variations of intracellular density during the cell cycle arise from tip-growth regulation in fission yeast

Emrah Bostan, Pascal Damian Odermatt

Intracellular density impacts the physical nature of the cytoplasm and can globally affect cellular processes, yet density regulation remains poorly understood. Here, using a new quantitative phase imaging method, we determined that dry-mass density in fis ...

Centromeres are dismantled by foundational meiotic proteins Spo11 and Rec8

Eftychia Kyriacou

Meiotic processes are potentially dangerous to genome stability and could be disastrous if activated in proliferative cells. Here we show that two key meiosis-defining proteins, the topoisomerase Spo11 (which forms double-strand breaks) and the meiotic coh ...

The N-Terminal Region of Yeast Protein Phosphatase Ppz1 Is a Determinant for Its Toxicity

Maria Lopez Malo

The Ppz enzymes are Ser/Thr protein phosphatases present only in fungi that are characterized by a highly conserved C-terminal catalytic region, related to PP1c phosphatases, and a more divergent N-terminal extension. In Saccharomyces cerevisiae, Ppz phosp ...

Yeast Nanometric Scale Oscillations Highlights Fibronectin Induced Changes in C. albicans

Giovanni Dietler, Sandor Kasas, Leonardo Venturelli, Anne-Céline Verenna Kohler

Yeast resistance to antifungal drugs is a major public health issue. Fungal adhesion onto the host mucosal surface is still a partially unknown phenomenon that is modulated by several actors among which fibronectin plays an important role. Targeting the ye ...

Single yeast cell nanomotions correlate with cellular activity

Giovanni Dietler, Sandor Kasas, María Inés Villalba, Anton Malovichko

Living single yeast cells show a specific cellular motion at the nanometer scale with a magnitude that is proportional to the cellular activity of the cell. We characterized this cellular nanomotion pattern of nonattached single yeast cells using classical ...

Time-lapse high-resolution microscopy to study the morphogenesis of microorganisms

Mélanie Thérèse Marie Hannebelle

Mycobacterium tuberculosis, the etiological agent for the tuberculosis disease, is a bacterial pathogen thought to infect about a quarter of the global human population. It is the first cause of death among infectious diseases, and is most prevalent in low ...

A biphasic growth model for cell pole elongation in mycobacteria

Georg Fantner, John McKinney, Mélanie Thérèse Marie Hannebelle, Haig Alexander Eskandarian, Chiara Toniolo, Joëlle Xiao Yuan Ven, Gaëlle Madeleine Vuaridel

Mycobacteria grow by inserting new cell wall material in discrete zones at the cell poles. This pattern implies that polar growth zones must be assembled de novo at each division, but the mechanisms that control the initiation of new pole growth are unknow ...

redLips: a comprehensive mechanistic model of the lipid metabolic network of yeast

Vassily Hatzimanikatis, Sofia Tsouka

Over the last decades, yeast has become a key model organism for the study of lipid biochemistry. Because the regulation of lipids has been closely linked to various physiopathologies, the study of these biomolecules could lead to new diagnostics and treat ...

Adaptive damage retention mechanism enables healthier yeast population

Riccardo Dainese

During cytokinesis in budding yeast (Saccharomyces cerevisiae) damaged proteins are distributed asymmetrically between the daughter and the mother cell. Retention of damaged proteins is a crucial mechanism ensuring a healthy daughter cell with full replica ...

Labor division in engineered cross-kingdom consortia: Consolidated bioprocessing of lignocellulosic biomass to carboxylic acids

Robert Lawrence Shahab

Lignocellulose is a renewable source of fixed carbon and a promising substrate for the production of chemicals and fuels in second generation biorefineries. In this thesis, we engineered artificial microbial consortia for consolidated bioprocessing (CBP) o ...

Casein kinase 2 mediated phosphorylation of Spt6 modulates histone dynamics and regulates spurious transcription

Eric Paquet

CK2 is an essential protein kinase implicated in various cellular processes. In this study, we address a potential role of this kinase in chromatin modulations associated with transcription. We found that CK2 depletion from yeast cells leads to replication ...

Modulation of the endogenous production of protoporphyrin IX in a yeast - based model organism

Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli

The main aim of this study was to assess conditions at which simple yeast-based model organism produces maximal levels of protoporphyrin IX (PpIX) after an exogenous administration of its precursor, 5-aminolevulinic acid (ALA), and the ferrous-ion chelator ...
