Scp160 deletion suppresses TDP-43 aggregation and toxicity in Saccharomyces cerevisiae
October 8, 2026
Deletion of SCP160 or BFR1 reduces TDP-43 toxicity without lowering TDP-43 protein abundance and suppresses prominent TDP-43, Htt103Q, and VHL aggregation, while SCP160 deletion also shifts residual TDP-43 foci toward the ER.
Sorbic acid triggers rapid formation of proteasome storage granules in Saccharomyces cerevisiae
August 12, 2026
This study demonstrates that sorbic acid, a common food preservative, induces the fastest reported proteasome storage granule (PSG) formation in yeast within 30 min, highlighting differences from other PSG-inducing conditions like acetic acid stress.
Fungistatic effect of sorbic acid on yeast cells via translational repression involving eIF2α phosphorylation and formation of Ded1- and eIF2B-granules
June 17, 2026
The findings of this study provide new insights into the physiological effects of sorbic acid on yeast cells, specifically regarding the regulation of translation-related factors.
Sir2 regulates selective autophagy in stationary-phase yeast cells
January 21, 2026
This study establishes Sir2 as a previously unrecognized regulator of selective autophagy during the stationary phase and highlight how cells dynamically control organelle degradation.
Microwave-assisted preparation of yeast cells for ultrastructural analysis by electron microscopy
November 18, 2024
Budding yeast Saccharomyces cerevisiae is widely used as a model organism to study the biogenesis and architecture of organellar membranes, which can be visualized by transmission electron microscopy (TEM).
The cAMP-PKA signalling crosstalks with CWI and HOG-MAPK pathways in yeast cell response to osmotic and thermal stress
March 15, 2024
During industrial fermentation yeast strains are exposed to fluctuations in oxygen concentration, osmotic pressure, pH, ethanol concentration, nutrient availability and temperature. The scope of this review is to outline the advancement of knowledge about the cAMP-PKA signalling and the crosstalk of this pathway with the CWI and HOG-MAPK cascades in response to the environmental challenges heat and hyperosmotic stress.
Replicative aging in yeast involves dynamic intron retention patterns associated with mRNA processing/export and protein ubiquitination
February 27, 2024
Saccharomyces cerevisiae has yielded relevant insights into some of the basic mechanisms of organismal aging. Among these are genomic instability, oxidative stress, caloric restriction and mitochondrial dysfunction. Our work uncovers a previously unexplored layer of the transcriptional program of yeast aging and, more generally, expands the knowledge on the occurrence of alternative splicing in baker´s yeast.
