Ser/Thr protein phosphatases in fungi: structure, regulation and function
April 24, 2019
In this work we present the members of this family in S. cerevisiae and other fungal species, and review the most recent findings concerning their regulation and the roles they play in the most diverse aspects of cell biology.
Forty-five-year evolution of probiotic therapy
April 2, 2019
The field of probiotics has greatly expanded over the past 45 years, driven by the need for safer alternatives to drugs, interest in natural microbial products, and clinical proof of effectiveness, with scientific formulations increasingly defining the market and promising applications for various health areas expected in the future.
Mitochondria-Associated Membranes (MAMs) are involved in Bax mitochondrial localization and cytochrome c release
March 15, 2019
This study investigated the role of Mitochondria-Associated Membranes (MAMs) in the regulation of apoptosis by analyzing the localization and function of the pro-apoptotic protein Bax in yeast, finding that disruption of MAMs by deletion of the MDM34 gene affects Bax's mitochondrial localization and the release of cytochrome c.
Chlamydia pneumoniae is present in the dental plaque of periodontitis patients and stimulates an inflammatory response in gingival epithelial cells
March 11, 2019
This study found that Chlamydia pneumoniae is present more frequently in the dental plaque of individuals with periodontal disease, can invade human gingival epithelial cells causing inflammatory responses, and may therefore be a contributing factor to periodontal disease and a potential indicator of risk.
Role of pheromone recognition systems in creating new species of fission yeast
March 11, 2019
This article comments on work published by Seike at al. (PloS Biol., 2019), which demonstrated an “asymmetric” pheromone recognition system in the fission yeast Schizosaccharomyces pombe.
Adaptive bacterial response to low level chlorhexidine exposure and its implications for hand hygiene
March 7, 2019
This article shows that bacteria can adapt to low levels of Chlorhexidine digluconate (CHG), resulting in increased tolerance and cross-resistance to other antimicrobials, suggesting caution in the widespread use of CHG to minimize avoidable selection pressure for resistance.
Microevolution of the pathogenic yeasts Candida albicans and Candida glabrata during antifungal therapy and host infection
February 8, 2019
This review explores how Candida albicans and Candida glabrata, common fungal pathogens resistant to antifungal therapy, adapt and evolve within different environments, aiming to identify stable adaptive mechanisms as potential drug targets.
Simultaneous profiling of sexually transmitted bacterial pathogens, microbiome, and concordant host response in cervical samples using whole transcriptome sequencing analysis
January 24, 2019
This study used total RNA sequencing to analyze cervical samples from women at high risk for STIs, revealing that host transcriptional profiles can be linked to microbiome composition and STI infections, with implications for advancing our understanding of PID and identifying potential biomarkers.
Genome-wide analysis of yeast expression data based on a priori generated co-regulation cliques
January 22, 2019
The study demonstrates the use of predefined genome-wide expression cliques, derived from extensive microarray data, to effectively analyze and visualize the complete gene expression response across various cellular conditions in yeast.
In the beginning was the word: How terminology drives our understanding of endosymbiotic organelles
January 21, 2019
This In the Pit article argues that the naming conventions for biological entities influence research perspectives and methodologies, advocating for mitochondria and plastids to be classified and named as bacteria due to their endosymbiotic origins, with potential implications for our understanding of bacterial prevalence, definitions of the microbiome and multicellularity, and the concept of endosymbiotic domestication.
