Special Issue Information

Dear Colleagues,

This Special Issue is the continuation of our previous Special Issue entitled “Yeast: Molecular and Cell Biology".

The yeast known as Saccharomyces cerevisiae is a popular model organism that is widely used in genetic and biochemical studies. An advantage of heterothallic yeast is the ability to stably exist both in haploid and diploid states. This makes it possible to not only carry out traditional genetic analysis, but also to study such specific aspects of eukaryotic cells, as well as cell cycle regulation and meiosis. Yeast turned out to be a very convenient object for genetic engineering, allowing the both introduction of exogenous DNA on plasmids and the integration of genomes. A feature of yeast is the predominance of homologous recombination during such integration.

The genome of Saccharomyces cerevisiae was the first eukaryotic genome to be sequenced. Numerous yeast databases make it easy to find up-to-date information; one such popular database is https://www.yeastgenome.org/.

Yeasts are widely used to analyze the genes of other eukaryotic organisms, as well as to study genes associated with human diseases. It was in this yeast that a two-hybrid system was developed to characterize and search for various protein–protein interactions. Yeast is one of the popular organisms used for the production of heterologous proteins in biotechnology. Many plasmids and yeast strains are commercially available, including sets of different deletion strains.

This Special Issue primarily aims to highlight the advantages of yeast as a model organism. This can be in the form of a review, a mini-review, an original research article, or a short communication.

Brettanomyces yeasts play a relevant role in the fermentation industry, showing controversial behavior. There is growing interest in these yeasts in the fermentation industry as beer and bioethanol production, while in winemaking, they are considered spoilage microorganisms mainly used to produce ethyl phenols. These compounds may alter wine’s organoleptic characteristics, leading to significant economic loss. In this work, 45 Brettanomyces strains from seven different environments were genotyped and assayed for some oenological characters to investigate the possible relationship among sources of isolation, genotype characterization, and oenological characters. The results of biotyping showed four main clusters which were also distinguished according to the oenological characters. The oenological characters also distinguished the strains based on the isolation source, suggesting an overall relation between origin and biotypes. The negative correlation between fermentation rate and ethyl phenols production in the Brettanomyces population may indicate the adaptation to hostile environments differently from crop strains that showed the opposite behavior. The overall results contribute to clarifying some features of Brettanomyces yeasts, even if further investigations into the ability of these yeasts to colonize winemaking environments are needed.

In yeast Saccharomyces cerevisiae, there are two translation termination factors, eRF1 (Sup45) and eRF3 (Sup35), which are essential for viability. Previous studies have revealed that presence of nonsense mutations in these genes leads to amplification of mutant alleles (sup35-n and sup45-n), which appears to be necessary for the viability of such cells. However, the mechanism of this phenomenon remained unclear. In this study, we used RNA-Seq and proteome analysis to reveal the complete set of gene expression changes that occur during cellular adaptation to the introduction of the sup35-218 nonsense allele. Our analysis demonstrated significant changes in the transcription of genes that control the cell cycle: decreases in the expression of genes of the anaphase promoting complex APC/C (APC9, CDC23) and their activator CDC20, and increases in the expression of the transcription factor FKH1, the main cell cycle kinase CDC28, and cyclins that induce DNA biosynthesis. We propose a model according to which yeast adaptation to nonsense mutations in the translation termination factor genes occurs as a result of a delayed cell cycle progression beyond the G2-M stage, which leads to an extension of the S and G2 phases and an increase in the number of copies of the mutant sup35-n allele.

Proteasome inhibitors are used in the therapy of several cancers, and clinical trials are underway for their use in the treatment of glioblastoma (GBM). However, GBM becomes resistant to chemotherapy relatively rapidly. Recently, the overexpression of ribonucleotide reductase (RNR) genes was found to mediate therapy resistance in GBM. The use of combinations of chemotherapeutic agents is considered a promising direction in cancer therapy. The present work aimed to evaluate the efficacy of the combination of proteasome and RNR inhibitors in yeast and GBM cell models. We have shown that impaired proteasome function results in increased levels of RNR subunits and increased enzyme activity in yeast. Co-administration of the proteasome inhibitor bortezomib and the RNR inhibitor hydroxyurea was found to significantly reduce the growth rate of S. cerevisiae yeast. Accordingly, the combination of bortezomib and another RNR inhibitor gemcitabine reduced the survival of DBTRG-05MG compared to the HEK293 cell line. Thus, yeast can be used as a simple model to evaluate the efficacy of combinations of proteasome and RNR inhibitors. Full article

In a eukaryotic cell, the ratio of mitochondrial DNA (mtDNA) to nuclear DNA (nDNA) is usually maintained within a specific range. This suggests the presence of a negative feedback loop mechanism preventing extensive mtDNA replication and depletion. However, the experimental data on this hypothetical mechanism are limited. In this study, we suggested that deletions in mtDNA, known to increase mtDNA abundance, can disrupt this mechanism, and thus, increase cell-to-cell variance in the mtDNA copy numbers. To test this, we generated Saccharomyces cerevisiae rho− strains with large deletions in the mtDNA and rho0 strains depleted of mtDNA. Given that mtDNA contributes to the total DNA content of exponentially growing yeast cells, we showed that it can be quantified in individual cells by flow cytometry using the DNA-intercalating fluorescent dye SYTOX green. We found that the rho− mutations increased both the levels and cell-to-cell heterogeneity in the total DNA content of G1 and G2/M yeast cells, with no association with the cell size. Furthermore, the depletion of mtDNA in both the rho+ and rho− strains significantly decreased the SYTOX green signal variance. The high cell-to-cell heterogeneity of the mtDNA amount in the rho− strains suggests that mtDNA copy number regulation relies on full-length mtDNA, whereas the rho− mtDNAs partially escape this regulation.
