Barcode sequencing and a high-throughput assay for chronological lifespan uncover ageing-associated genes in fission yeast

Catalina A. Romila1,#, StJohn Townsend1,2,#, Michal Malecki1,3, Stephan Kamrad1,2,4, María Rodríguez-López1, Olivia Hillson1, Cristina Cotobal1, Markus Ralser2,5 and Jürg Bähler1

This work presents two approaches to study chronological lifespan (CLS) for medium- to high-throughput applications, a method for Bar-seq to identify mutants showing altered CLS and a novel medium-throughput colony-forming units assay that can be largely automated by robotics.

Proanthocyanidin-enriched cranberry extract induces resilient bacterial community dynamics in a gnotobiotic mouse model

Catherine C. Neto1,2,#, Benedikt M. Mortzfeld3,#, John R. Turbitt1,2, Shakti K. Bhattarai3, Vladimir Yeliseyev4, Nicholas DiBenedetto4, Lynn Bry4 and Vanni Bucci2,3

This study investigates the effect of a water-soluble, proanthocyanidin-rich cranberry juice extract on the short-term dynamics of a human-derived bacterial community in a gnotobiotic mouse model.

Dry biocleaning of artwork: an innovative methodology for Cultural Heritage recovery?

Giancarlo Ranalli1, Pilar Bosch-Roig2, Simone Crudele1, Laura Rampazzi3,4, Cristina Corti3 and Elisabetta Zanardini5

This work proposes an innovative methodology based on applied biotechnology for the recovery of altered stonework: the "dry biocleaning", which envisages the use of dehydrated microbial cells without the use of free water or gel-based matrices.

Aeration mitigates endoplasmic reticulum stress in Saccharomyces cerevisiae even without mitochondrial respiration

Huong Thi Phuong1, Yuki Ishiwata-Kimata1, Yuki Nishi1, Norie Oguchi1, Hiroshi Takagi1 and Yukio Kimata1

This work demonstrates a scenario, in which aeration acts beneficially on Saccharmyces cerevisiae cells even under fermentative conditions.

A novel BR-SMAD is required for larval development in barber’s pole worm Haemonchus contortus

Fangfang Li1, Peixi Qin1, Lisha Ye1, Nishith Gupta1,2,3 and Min Hu1

The herein presented results show a BMP-like receptor-regulated SMAD in Haemonchus contortus that is required for larval differentiation and underscore an adaptive functional repurposing of BMP-signaling in parasitic worms.

Nutrient sensing and cAMP signaling in yeast: G-protein coupled receptor versus transceptor activation of PKA

October 12, 2020

The herein presented work supports a model, in which nutrient transceptors are evolutionary ancestors of GPCRs, employing a more primitive direct signaling mechanism compared to the indirect cAMP second-messenger signaling mechanism used by GPCRs for activation of PKA.

Novobiocin inhibits membrane synthesis and vacuole formation of Enterococcus faecalis protoplasts

August 10, 2020

In this study Tsuchikado et al. show that DNA replication is crucial for plasma membrane biosynthesis and vacuole formation in Enterococcus faecalis protoplasts. Novobiocin inhibits DNA replication, blocking cell enlargement and vacuole formation. Extended treatment prevents re-enlargement after removal.

Variants of the human RAD52 gene confer defects in ionizing radiation resistance and homologous recombination repair in budding yeast

July 20, 2020

RAD52 is a key protein in DNA repair and suppresses DNA damage in yeast; however, certain variants affecting BRCA2 mutations fail to correct HRR defects. This suggests that HsRAD52 aids multiple DNA repair mechanisms and could be targeted for use in treating BRCA2-deficient cancers.

Histone H3E73Q and H4E53A mutations cause recombinogenic DNA damage

April 24, 2020

This study reveals that conserved residues H3E73 and H4E53 in histones H3 and H4 play a crucial role in maintaining genome stability. Mutations at these sites increase recombinogenic DNA damage, likely due to replication-associated issues rather than transcriptional activity, highlighting their importance in DNA damage prevention and repair.
