High hydrostatic pressure upregulate central carbon metabolism genes in a distillery yeast strain
Methods In this study we performed a microarray analysis in a distillery Saccharomyces cerevisiae strain (BT0510) submitted to sublethal pressure treatment of 50 MPa for 30 min at room temperature, followed by incubation for 5, 10 and 15 min at room pressure (0.1 MPa). The transcription of the genes involved in central carbon metabolism in response to HHP was investigated for bioinformatics tools.
متن کاملRegulation of cell cycle and stress responses to hydrostatic pressure in fission yeast.
We have investigated the cellular responses to hydrostatic pressure by using the fission yeast Schizosaccharomyces pombe as a model system. Exposure to sublethal levels of hydrostatic pressure resulted in G2 cell cycle delay. This delay resulted from Cdc2 tyrosine-15 (Y-15) phosphorylation, and it was abrogated by simultaneous disruption of the Cdc2 kinase regulators Cdc25 and Wee1. However, ce...
متن کاملMonitoring expression of yeast cell wall protein-encoding genes in response to high hydrostatic pressure
Background The cell wall (CW) is one of the most important structures of the yeast cell, accounting for up to 30% of its dry weight. This organelle determines cellular morphology, affords mechanical protection and provides osmotic support. The yeast CW is a dynamic structure susceptible to many modifications, adjusting its composition and thickness to environmental changes. These responses usua...
متن کاملHigh hydrostatic pressure
The use of high pressure processing (HPP) in the food industry was developed as an alternative to common thermal processes, such as pasteurization and sterilization, to produce a microbiologically safe food while avoiding and reducing undesirable changes in sensory, physiochemical and nutritional properties of foods. The use of high pressure at high temperatures as a tool for sterilization (hig...
متن کاملEffect of Hydrostatic Pressure on Pc12 Cell Line
Purpose: The present study was designed to investigate the effect of hydrostatic pressure on cell viability, apoptosis induction, morphology and cell-substrate interactions of PC12 cells. Materials and Methods: PC12 as a neuronal cell line maintained in RPMI 1640 culture medium supplemented with 10% fetal bovine serum. PC12 cells were subjected to hydrostatic pressure. Experimental pressure con...
