Live fast, die fast principle in a single cell of fission yeast

Hidenori Nakaoka1

This article comments on a recent study (Nakaoka and Wakamoto, PLoS Biol, 2017), which developed a microfluidics-based platform to track multiple single cell lineages until death.

Out with the old: Hsp90 finds amino acid residue more useful than co-chaperone protein

Abbey D. Zuehlke1 and Leonard Neckers1

This article comments on work published by Zuehlke et al (Nat Commun, 2017), which demonstrates that the function of one co-chaperone in yeast is replaced by posttranslational modification (PTM) of a single amino acid within Hsp90 in higher eukaryotes.

Having your cake and eating it – Staphylococcus aureus small colony variants can evolve faster growth rate without losing their antibiotic resistance

Gerrit Brandis1, Sha Cao1, Douglas L. Huseby1 and Diarmaid Hughes1

This article comments on work published by Cao et al. (mBio, 2027), which shows that Staphylococcus aureus can produce small colony variants (SCVs) that are challenging to detect and lead to persistent infections due to mutations affecting respiration and ATP production, with recent findings indicating various evolutionary paths for SCVs to increase growth rate while maintaining antibiotic resistance, suggesting greater adaptability and clinical challenge.

Integrative metabolomics as emerging tool to study autophagy regulation

Sarah Stryeck1, Ruth Birner-Gruenberger2, Tobias Madl1,*

This review summarizes the advancements in metabolomics, particularly using NMR spectroscopy and mass spectrometry, and its increasing role in biological research, offering insights into autophagy regulation with a focus on key metabolites, recent studies, and future prospects in elucidating complex regulatory mechanisms of autophagy and related diseases.

The interplay between transcription and mRNA degradation in Saccharomyces cerevisiae

Subhadeep Das1, Debasish Sarkar2 and Biswadip Das1

This review summarizes how the integration of mRNA synthesis and degradation, mediated by specialized promoters and "coordinators," shapes the cellular transcriptome and plays a significant role in regulating gene expression profiles in various biological processes and potentially enhances evolutionary rates.

Inhibitors of glycosomal protein import provide new leads against trypanosomiasis

Vishal C. Kalel1, Leonidas Emmanouilidis2,3, Maciej Dawidowski2,3,4, Wolfgang Schliebs1, Michael Sattler2,3, Grzegorz M. Popowicz2,3, Ralf Erdmann1

This article comments on work published by Dawidowski et al. (Science, 2017), which provides the grounds for further development of the glycosome inhibitors into clinical candidates and validates the parasite protein-protein interactions as drug targets.

Impact of the host on Toxoplasma stage differentiation

Carsten G.K. Lüder1 and Taibur Rahman1

This review summarizes how Toxoplasma gondii transitions from an acute to a chronic infection in warm-blooded animals and humans through a developmental switch influenced by host cell physiology, which determines parasite persistence mainly in neural and muscular tissues.

Chlamydia and mitochondria – an unfragmented relationship

Suvagata Roy Chowdhury1 and Thomas Rudel1

This article comments on work published by Chowdhury et al (J Cell Biol, 2017), which demonstrated that Chlamydia infection induces and requires an upregulation of the host miRNA, miR-30c-5p (miR-30c) to ameliorate infection induced stress on the host mitochondrial architecture and hinders induction of apoptosis.

Protein aggregation triggers a declining libido in elder yeasts that still have a lust for life

Fabrice Caudron

This article comments on work published by Schlissel et al (Science 2017), showing that aging in yeast does not lead to the expected loss of heterochromatin silencing due to Sir2 inactivity, but rather to reduced mating pheromone sensitivity caused by the aggregation of the RNA-binding protein Whi3, which can be reversed by eliminating Whi3's polyglutamine domain.

Genome-wide studies of telomere biology in budding yeast

March 1, 2014

In the last decade, technical advances have allowed carrying out systematic genome-wide screens for mutants affecting various aspects of telomere biology. In this review we summarize these efforts, and the insights that this Systems Biology approach has produced so far.
