Hormesis: a fundamental concept in biology
Edward J. Calabrese
This article addresses the concept of hormetic dose response, which describes the limits to which integrative endpoints can be modulated (i.e., enhanced or diminished) by pharmaceutical, chemical and physical means.
Live longer on MARS: a yeast paradigm of mitochondrial adaptive ROS signaling in aging
Gerald S. Shadel
In this article, the potential relevance of Mitochondrial Adaptive ROS Signaling (MARS) to the human disease Ataxia-Telangiectasia and as a potential anti-aging target is discussed.
Prokaryotic Argonautes – variations on the RNA interference theme
John van der Oost1, Daan C. Swarts1, Matthijs M. Jore1,2
This article comments on work published by Swarts et al. (Nature, 2014), which demonstrates that Argonaute family protein of the bacterium Thermus thermophilus acts as a barrier for the uptake and propagation of foreign DNA.
Longevity pathways and maintenance of the proteome: the role of autophagy and mitophagy during yeast ageing
Belém Sampaio-Marques1,2, William C. Burhans3, Paula Ludovico1,2
This review describes recent findings that shed light on how longevity pathways and metabolic status impact maintenance of the proteome in both yeast ageing paradigms. These findings demonstrate that yeast remain a powerful model system for elucidating these relationships and their influence on ageing regulation.
Secondary structures involving the poly(A) tail and other 3’ sequences are major determinants of mRNA isoform stability in yeast
Zarmik Moqtaderi#, Joseph V. Geisberg# and Kevin Struhl
This article comments on work published by Geisberg et al. (Cell (2014), which points to an important role for mRNA structure at 3’ termini in governing transcript stability, likely by reducing the interaction of the mRNA with the degradation apparatus.
De novo peroxisome biogenesis revisited
Marten Veenhuis and Ida J. van der Klei
This article comments on work published by Knoops et al. (JCB, 2014), which describes an alternative peroxisome formation pathway in yeast pex3 and pex19 cells, which relies on the existence of small peroxisomal remnants that are present in these cells.
Transcriptional and genomic mayhem due to aging-induced nucleosome loss in budding yeast
Zheng Hu1, Kaifu Chen2, Wei Li2 and Jessica K. Tyler2
This article comments on work published by Zheng et al. (Genes and Development, 2014), which investigated a loss of histones during replicative aging in budding yeast, which was also accompanied by a significantly-increased frequency of genomic instability including DNA breaks, chromosomal translocations, retrotransposition, and transfer of mitochondrial DNA into the nuclear genome.
The Parkinson’s disease-associated protein α-synuclein disrupts stress signaling – a possible implication for methamphetamine use?
Shaoxiao Wang1 and Stephan N. Witt1,2
This article comments on work published by Wang et al. (PNAS, 2012), which reported that human α-syn, at high expression levels, disrupts stress-activated signal transduction pathways in both yeast and human neuroblastoma cells. Disruption of these signaling pathways ultimately leads to vulnerability to stress and to cell death.
Massive gene swamping among cheese-making Penicillium fungi
Jeanne Ropars1,2, Gabriela Aguileta1,2,3, Damien M. de Vienne4,5 and Tatiana Giraud1,2
This article comments on work published by Cheeseman et al. (Nat Comm, 2014), which indicates that horizontal gene transfer is a crucial mechanism of rapid adaptation, even among eukaryotes.
Prohibitins: emerging host targets of bacteria and viruses at the plasma membrane, mitochondria, and cytoplasm
June 3, 2026
Prohibitins are emerging as central host hubs exploited by bacteria and viruses to rewire signaling and mitochondrial dynamics. The current review discusses Prohibitins in host-pathogen interplay and their potential as novel anti-infective targets.
Outer membrane vesicles in Vibrio species: Roles in biofilm formation and pathogenesis
June 2, 2026
This review explores current knowledge on outer membrane vesicles (OMVs) in Vibrio species, highlighting their roles in pathogenesis, host interaction, and marine ecology; and identifies major knowledge gaps, outlining key methodological challenges and future prospects for OMV-based applications.
The mechanism of Tat-dependent protein translocation
May 15, 2026
This review integrates mechanistically relevant biochemical, molecular, and structural studies on Tat-dependent translocation of folded proteins into an in its molecular detail new comprehensive explanation of how the Tat system mediates protein transport.
Protein arginine methyltransferases in protozoan parasites: a new path for antiparasitic chemotherapy?
February 12, 2026
This review discusses the activity and the relevance of arginine methyltransferases for the survival of pathogenic kinetoplastids, apicomplexans and amoebas, and how these enzymes could be exploited as drug targets.
Gut microbiota and ankylosing spondylitis: current insights and future challenges
August 25, 2025
This review explores the growing role of gut microbiota in AS and its potential to reshape targeted treatment strategies and facilitate development of adjunct therapies to address disease onset and progression.
Advancements in vaginal microbiota, Trichomonas vaginalis, and vaginal cell interactions: Insights from co-culture assays
May 15, 2025
This review updates co-culture and co-incubation techniques for studying interactions of Lactobacillus spp., representing a pre-dominant member of the healthy vaginal microbiota; Candida spp., the most abundant yeast in the vagina, and T. vaginalis, responsible for the most widespread nonviral STI worldwide.
Influence of cervicovaginal microbiota on Chlamydia trachomatis infection dynamics
April 15, 2025
This review examines the complex interplay between the cervicovaginal microbiome, C. trachomatis infection, and host immune responses, highlighting the role of metabolites such as short-chain and long-chain fatty acids, indole, and iron in modulating pathogen survival and host defenses.
Unveiling the molecular architecture of the mitochondrial respiratory chain of Acanthamoeba castellanii
March 31, 2025
This review provides a comprehensive overview of the mitochondrial res-piratory chain in A. castellanii, focusing on the key alternative components involved in oxidative phosphorylation and their roles in energy metabolism, stress response, and adaptation to various conditions.
