Caspase 3 exhibits a yeast metacaspase proteostasis function that protects mitochondria from toxic TDP43 aggregates

July 10, 2023

Caspase 3 activation is a hallmark of cell death and there is a strong correlation between elevated protease activity and evolving pathology in neurodegenerative disease, such as amyotrophic lateral sclerosis (ALS). These results suggest that caspase 3 is not inherently pathogenic, but may act as a compensatory proteostasis factor, to limit TDP-43 protein inclusions and protect organelle function in aggregation related degenerative disease.

Metallothionein Cup1 attenuates nitrosative stress in the yeast Saccharomyces cerevisiae

July 10, 2023

Our findings suggest that the yeast metallothionein Cup1 contributes to nitrosative stress tolerance, possibly as a constitutive rather than an inducible defense mechanism.

GFP fusions of Sec-routed extracellular proteins in Staphylococcus aureus reveal surface-associated coagulase in biofilms

June 28, 2023

We show that msfGFP can be used to generate extracellular fluorescent fusion proteins in S. aureus, applicable for proteins that are secreted through the Sec pathway. When fused to coagulase, msfGFP did not hinder the biological function, and the fusion protein localised to the fibrin pseudocapsule surrounding clusters of S. aureus cells.

Ribose 5-phosphate: the key metabolite bridging the metabolisms of nucleotides and amino acids during stringent response in Escherichia coli?

June 1, 2023

Here we propose the metabolite ribose 5’-phosphate as the key link between nucleotide and amino acid metabolisms and a working model integrating both the transcriptional and metabolic effects of (p)ppGpp on E. coli physiological adaptation during the stringent response.

Atg1, a key regulator of autophagy, functions to promote MAPK activation and cell death upon calcium overload in fission yeast

May 10, 2023

Here, we provide evidence that the fission yeast Atg1 regulates cell death responses upon intracellular calcium load in addition to its role in promoting Pmk1 MAPK.

Infinity war: Trichomonas vaginalis and interactions with host immune response

March 31, 2023

Trichomonas vaginalis is the pathological agent of human trichomoniasis with an incidence of 156 million cases worldwide. This review highlights parasite strategies to activate and stimulate or evade variated and complex immunological mechanisms related to the symptoms and clinical complications observed here.

Acetate modulates the inhibitory effect of Lactobacillus gasseri against the pathogenic yeasts Candida albicans and Candida glabrata

March 21, 2023

The results herein described advance the design of new anti-Candida therapies based on probiotics, in particular, those based on vaginal lactobacilli species, helping to reduce the significant burden that infections caused by Candida have today in human health.

D-Serine reduces the expression of the cytopathic genotoxin colibactin

March 8, 2023

Sensing and responding to environmental cues and signalling molecules is crucial for bacterial survival. In this study we have identified a D-amino acid that has a strong regulatory effect on the pks genomic island which encodes for biosynthesis genes for the genotoxic compound colibactin.

A modular cloning (MoClo) toolkit for reliable intracellular protein targeting in the yeast Saccharomyces cerevisiae

February 28, 2023

In this study, we describe an advanced Molecular cloning toolkit that is designed for the baker’s yeast Saccharomyces cerevisiae and optimized for the targeting of proteins of interest to specific cellular compartments.
