Transcription profiling of Pichia pastoris wild type vs recombinant Fab expressing strain with different osmolarities

ABSTRACT: Pichia pastoris was grown in carbon limited chemostat cultures on mineral medium with glucose as carbon source. 3 different osmolarities were selected (140, 850, 1400mOsmol kg-1). Samples were taken at steady-state, thus the effect of osmolarity in adapted cells was monitored.

Transcription profiling by array of condition dependent regulation of lipid metabolism in Saccharomyces cerevisiae

Project description:Investigation of lipid metabolism as a function of three experimental factors: 1) aerobicity (aerobic vs anaerobic, or 'A' vs 'O'), 2) nutrient limitation (carbon vs nitrogen limitation, or 'C' vs 'N'), 3) temperature (30C vs 15C, or 'T' vs 't') using a full factorial design.

Transcription profiling of Aspergillus niger grown in media containg different pectic substrates to study the pectinolytic system

Project description:To study the induction of the genes encoding known and putative enzymes from the pectinolytic system of A. niger, the transcriptional profiles of 58 selected known or putative pectinolytic genes were monitored by microarray experiments. For this purpose, A. niger was cultivated on the complex substrates, sugar beet pectin and polygalacturonic acid as primary carbon sources. Galacturonic acid, rhamnose and xylose were used to assess the effects on gene expression caused by simple well-defined carbon sources, representing the most abundant sugar residues present in the backbone of pectin. Fructose, as a strong repressor of the expression of genes that are under carbon catabolite regulation, and sorbitol, as a non-inducing sugar-like alcohol, which does not affect the carbon catabolite regulation mechanisms were selected as control substrates. Mycelia of A. niger were pregrown for 18 h on 2% fructose, transferred to medium containing the different pectic and control substrates, and sampled at four time points during 24 h of incubation.

Comparison of gene expression profile among Pichia pastoris strain with a different gene dosage

Project description:Pichia pastoris is a widely used yeast platform for heterologous protein production. Although increasing gene dosage is a powerful strategy to improve recombinant protein production, an excess in the number of gene copies often leads to decreased product yields and increased metabolic burden. In order to find the bottlenecks of this strategy, here we present a transcriptome profile comparison of a series of Pichia pastoris strains carrying a different gene dosage of the Rhizopus oryzae lipase (Rol) as a model protein. Cells were grown on a mixture of glycerol:methanol in chemostat cultures. 2 color experiment in reference design.

Transcription profiing of a yeast strain containing 2 extra copies of Abf2p compared to its wild type counterpart

Project description:We compared the RNA expression profile from a Saccharomyces cerevisiae yeast strain (3xABF2) containing two (2) extra copies of Abf2p, a mtDNA maintenance factor, to the signal from its wild type counterpart (14ww). The two strains used have been described in Genetics 148: 1763-1776.

The CRE1 carbon catabolite repressor of the fungus Trichoderma reesei: a master regulator of carbon assimilation

Project description:The identification and characterization of the transcriptional regulatory networks governing the physiological behaviour and adaptation of microbial cells is a key step in understanding their behaviour. One such wide-domain regulatory circuit, essential to all cells, is carbon catabolite repression (CCR): it allows the cell to prefer some carbon sources, whose assimilation is of high nutritional value, over less profitable ones. This system has been investigated in bacteria, yeast and filamentous fungi. In the latter, the C2H2 zinc finger protein has been shown to act as the central transcriptional repressor in this process. Here, we deciphered the CRE1 regulon by profiling transcription in a wild-type and delta-cre1 mutant strains on glucose in the model cellulose and hemicellulose-degrading fungus Trichoderma reesei (anamorph of Hypocrea jecorina) at constant growth rates known to per se repress and derepress CCR-affected genes. Two biological pool by condition in dye switch. For the two biological replicates on each four experiments we apply on the pretreated results the linear modeling approach implemented by lmFit and the empirical Bayes statistics implemented by eBayes from the limma R package (Smyth 2004). We select the list of statistically regulated genes using a 5% significance threshold.
