Quantitative characterization of the inorganic phosphate gene regulatory networks in S. cerevisiae and bottom up engineering an orthogonal gene network

Gene regulatory networks (GRNs) play a crucial role in an organism's response to changing environmental conditions. Cellular behaviors typically result from the integration of multiple gene outputs, and their regulation often demands precise control of num ...

Modulation of the nanoscale motion rate of Candida albicans by X-rays

Sandor Kasas, María Inés Villalba

IntroductionPatients undergoing cancer treatment by radiation therapy commonly develop Candida albicans infections (candidiasis). Such infections are generally treated by antifungals that unfortunately also induce numerous secondary effects in the patient. ...

Mitochondrial nanomotion measured by optical microscopy

Sandor Kasas, María Inés Villalba, Priyanka Parmar

Nanometric scale size oscillations seem to be a fundamental feature of all living organisms on Earth. Their detection usually requires complex and very sensitive devices. However, some recent studies demonstrated that very simple optical microscopes and de ...

SLC25A51 is a mammalian mitochondrial NAD(+) transporter

Kai Johnsson, Liang Wang

Mitochondria require nicotinamide adenine dinucleotide (NAD(+)) to carry out the fundamental processes that fuel respiration and mediate cellular energy transduction. Mitochondrial NAD(+) transporters have been identified in yeast and plants(1,2), but thei ...

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 ...

Atomic Force Microscopy of Biological Systems: Quantitative Imaging and Nanomotion Detection

Petar Stupar

The core of this thesis is the application of different modalities of atomic force microscopy to study living systems. After a brief introduction, quantitative imaging state of the art is presented and the applications for mammalian, plant, bacterial, and ...

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 ...

An automated microreactor for semi-continuous biosensor measurements

Philippe Renaud, Harald Van Lintel, Nina Buffi, Jan Roelof van der Meer

Living bacteria or yeast cells are frequently used as bioreporters for the detection of specific chemical analytes or conditions of sample toxicity. In particular, bacteria or yeast equipped with synthetic gene circuitry that allows the production of a rel ...

Optimization and characterization of the endogenous production of protoporphyrin IX in a yeast model

Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli, Matthieu Philippe Emmanuel Zellweger

The availability of reproducible, convenient, and inexpensive model organisms able to generate predictable levels of endogenous porphyrins, including protoporphyrin IX (PpIX), is essential in photomedicine research. Saccharomyces cerevisiae produces endoge ...
