Comparison between stationary phase S. cerevisiae H155 cells, exponential phase cells and stressed cells

ABSTRACT: The sensibility of the used low-density arrays was tested by applying the lab strain S. cerevisiae H155. Important abiotic parameters were tested as they were introduced as elevated osmotic, pH or ethanol stress to the cells. Results from one loop including samples from cells in five different conditions are summarized in this study. Microarrays were hybridized in a loop approach.

Bottom-fermenting Saccharomyces pastorianus strains driving brewing fermentation processes are usually reused several times. It is still unclear, whether the number of successions may have an impact on cell physiology prompting consequences for brewing quality. In this study, fermentation performance of up to twenty consecutive runs in a brewery was investigated. For each run mRNA expression levels of cellular marker molecules, which are known to correlate with metabolism, hexose transport, agin ...[more]

Comparison between all runs of a serial repitching in brewery A

Project description:The aim of this study was to identify differently expressed genes between all 6 runs of brewery A. A run describes the industrial fermentation of brewery wort. By the end of fermentation the yeast slurry is cropped. These cells are reused for inoculation of another cylindro-conical vessel (CCVs). Results from two loops of two different breweries are summarized in this study. The samples were taken from two serial repitchings of a two breweries. Microarrays were hybridized in a loop approach.

Comparison between all runs of industrial serial repitching 1

Project description:The aim of this study was to identify differently expressed genes between all runs of four serial repitchings from a German brewery. In the brewery the number of successive runs varied from 17 to 20. A run describes the industrial fermentation of brewery wort. By the end of fermentation the yeast slurry is cropped. These cells are reused for inoculation of another cylindro-conical vessel (CCVs). Results from four loops are summarized in this study. The samples were taken from four serial repitchings of a German brewery (brewery A). Microarrays were hybridized in a loop approach.

Comparison of C3 or C3156-181-peptide treated Isolated primary rat neonatal Sschwann Cells after 72 h

Project description:The aim of this study was to identify differently expressed genes between C3 or C3156-181-peptide treated Isolated primary rat neonatal Schwann Cells. To elucidate the unresolved mechanism behind the promoting effect of C3156-181 on PNR we cultured primary rat neonatal SCs and treated them for up to 72 h with C3 or C3156-181. We then performed gene expression microarray analysis Results from two loops of two different treatment times are summarized in this study. The samples were taken from two C3 or C3156-181-peptide treated Isolated primary rat neonatal Schwann Cell cultures. Microarrays were hybriszed in a loop approach. Results from two loops that map to two different sampling times (loop1: after 12 hours, loop2: after 72) are compared in this study. The data in this file represents loop2. The samples were taken from The samples were taken from untreated, C3 or C3156-181-peptide treated Isolated primary rat neonatal Schwann Cells.

Investigation of colominic acid effects on immortalized Schwann cells

Project description:The purpose of the present study is to influence of CA coating on immortalized Schwann cells in vitro in comparison to standard culture conditions as well as to laminin as a positive standard. CA is a homopolymer of polysialic acid (PSA), which has â attached to the neuronal cell adhesion molecule (NCAM) â emerged as particulate attractive candidate for promoting morphological plasticity of axonal processes during axonal path finding and activity-dependent remodelling. For this purpose self-spotted microarrays with 352 neurospecific genes were hybridized with mRNA from immortalized Schwann cells cultivated on different coating conditions: In order to enable a comprehensive comparison to the established coating material laminin as well as to standard coating conditions (cultivation on the cell culture surface) a loop-design has been chosen, which is based on the dye-swap design and facilitates a direct comparison of the different states. Results from 3 microarrays are summarized in this study. The samples originate from different coatings. Microarrays were hybridized in a loop design with one common reference using a dye swap approach.

Comparison between a first and a last run of industrial serial repitching

Project description:The aim of this study was to identify differently expressed genes between first and last runs of serial repitchings from four different German breweries. In the breweries the number of successive runs varied from 4 to 22. A run describes the industrial fermentation of brewery wort. By the end of fermentation the yeast slurry is cropped. These cells are reused for inoculation of another cylindro-conical vessel (CCVs). Results from eight microarrays are summarized in this study. The samples were taken from four German breweries. Microarrays were hybridized in a dye swap approach: Dye-swap 1: brewery A runs 1 vs. 22; Dye-swap 2: brewery B runs 1 vs. 5; Dye-swap 3: brewery C runs 1 vs. 4; Dye-swap 4: brewery D runs 1 vs. 8
