A faithful cell division is essential for proper cellular proliferation of all eukaryotic cells; indeed the correct segregation of the genetic material allows daughter cells to proceed into the cell cycle safely. Conversely, errors during chromosome partition generate aneuploid cells that have been associated to several human pathological conditions, including cancer. Given the importance of this issue, all the steps that lead to cell separation are finely regulated. The budding yeast is a unicellular eukaryotic organism that divides asymmetrically and it is a suitable model system to study the regulation of cell division. Humans and budding yeast are distant 1 billion years of evolution, nonetheless several essential pathways, proteins, and cellular structures are conserved. Among these, the mitotic spindle is a key player in chromosome segregation and its correct morphogenesis and functioning is essential for genomic stability. In this review we will focus on molecular pathways and proteins involved in the control mitotic spindle morphogenesis and function that are conserved from yeast to humans and whose impairment is connected with the development of human diseases.

Background: Continuous fermentation offers advantages in improving production efficiency and reducing costs, making it highly competitive for industrial ethanol production. A key requirement for Saccharomyces cerevisiae strains used in this process is their tolerance to high ethanol concentrations, which enables them to adapt to continuous fermentation conditions. To explore how yeast cells respond to varying levels of ethanol stress during fermentation, a two-month continuous fermentation was conducted.

This paper describes the design, development, synthesis, in silico, and in vitro evaluation of fourteen novel heterocycle hybrids as inhibitors of the α-glucosidase enzyme. The primary aim of this study was to explore the potential of novel pyrazole-phthalazine hybrids as selective inhibitors of α-glucosidase, an enzyme involved in carbohydrate metabolism, which plays a key role in the management of type 2 diabetes. The rationale for this study stems from the need for new, more effective inhibitors of α-glucosidase with improved efficacy and safety profiles compared to currently available therapies like Acarbose.
