Project description:Four groups of C57 mice were gavaged with CMC, ethanol, DEHP and ethanol+DEHP for 28 continuous days. At the end of the experiment, livers were harvested to carry out Whole genome resequencing, we found that metabolism related genes were significantly changed in the DEHP and ethanol+DEHP groups compared with control groups, but there was no significant change between them.

Project description:Small interspersed elements (SINEs) is transcribed by RNA polymerase III (Pol III) to produce RNAs of typically 100 to 500 nucleotides in length. Although the abundance of SINE RNAs can be analyzed by Northern blotting and primer extension, the nature (sequence, exact length, and genomic origin) of these RNAs cannot be revealed by these methods. Moreover, mRNA sequencing (mRNA-seq) is not able to distinguish bona fide SINE RNAs and SINE sequences present in longer transcripts. To elucidate the abundance, source loci, and sequence nature of SINE RNAs, we have established a deep sequencing method, designated as melRNA-seq (medium length RNA-seq), which can determine whole-length sequences of RNAs. The total RNA samples were treated with 5' Pyrophosphohydrolase (RppH), which allowed ligation of an RNA adaptor to the 5’ end of intact SINE RNAs. Another adaptor was ligated to the 3’ end, followed by reverse transcription, PCR amplification, size selection, and single-end deep sequencing. Analysis of two biological replicates of RNAs from mouse spermatogonia showed high reproducibility of the SINE expression data both at family level and locus level. Therefore, this new method can be used for the quantification and detailed sequence analysis of medium length non-coding RNAs, such as rRNA, snRNA, tRNAs, and SINE RNAs. The dynamic range is much wider than Northern blotting and primer extension.

Project description:Copy Number Variations (CNVs) were identified performing Comparative Genomic Hybridization (CGH) on 225 patients after whole-genome amplification, using Agilent SurePrint G3 4x180K microarrays. CNVs were further integrated with gene expression (Affymetrix U133+2 arrays) and mutations (targeted DNA resequencing). Complete description of the methods, array quality checks and called segments are available as supplemental material in the corresponding publication.

Project description:Background: Evolutionary engineering is a powerful approach to isolate suppressor mutants and industrially relevant genotypes. Until recently, DNA microarray analysis was the only affordable genome-wide approach to identify the responsible mutations. This situation has changed due to the rapidly decreasing costs of whole genome (re)sequencing. DNA microarray-based mRNA expression analysis and whole genome resequencing were combined in a study on lactate transport in Saccharomyces cerevisiae. Jen1p is the only S. cerevisiae lactate transporter reported in literature. To identify alternative lactate transporters, a jen1Δ strain was evolved for growth on lactate. Results: Two independent evolution experiments yielded Jen1p-independent growth on lactate (μmax 0.14 and 0.18 h-1 for single-cell lines IMW004 and IMW005, respectively). Whereas mRNA expression analysis did not provide leads, whole-genome resequencing showed different single nucleotide changes (C755G/Leu219Val and C655G/Ala252Gly) in the acetate transporter gene ADY2. Analysis of mRNA levels and depth of coverage of DNA sequencing combined with karyotyping, gene deletions and diagnostic PCR showed that in IMW004 an isochromosome III (~475 kb), which contains two additional copies of ADY2C755G, was formed via crossover between YCLWΔ15 and YCRCΔ6. Introduction of the ADY2 alleles in a jen1 ady2 strain resulted in growth on lactate (μmax 0.14 h-1 for Ady2pLeu219Val and 0.12 h-1 for Ady2pAla252Gly). Conclusions: Whole-genome resequencing of yeast strains obtained from independent evolution experiments enabled rapid identification of a key gene that was not identified by mRNA expression analysis of the same strains. Reverse metabolic engineering showed that mutated alleles of ADY2 (C655G and C755G) encode efficient lactate transporters.
