Project description:In this study, we designed a space simulation study, named “4 Subjects 180-Day Controlled Ecological Life Support System (CELSS) Integration Experiment”, which took place in Shenzhen, China, from June to December 2016. In this experiment, four subjects (3 males and 1 female) lived for 180 days in an enclosed simulated cabin, and multiple-sampling-point DNA methylation data was collected to conduct the epigenic analysis. Peripheral whole blood cells were extracted from all 4 subjects on the 12 sampling points (Pre45, Pre15, R2, R30, R60, R75, R90, R105, R120, R150, R175 and Post30 mission day during the experiment).
Project description:MAGE-seq amplicon data from the paper RNA structural determinants of optimal codons revealed by MAGE-seq in Cell Systems 2016 by Kelsic, Chung, Cohen, Park, Wang & Kishony. Data contains read counts for PCR amplicons of the Escherichia coli gene infA: 1) Single codon mutants tiling along the entire gene, with timepoints from growth doublings in rich and minimal medias. 2) Codon pair mutants for positions at the beginning of the gene with timepoints for growth doublings in rich media. 3) Mutations in a hairpin of the 5' UTR for growth in rich media.
Project description:Contaminated aquifer (Dusseldorf-Flinger, Germany) templates extracted from 5 sediment depths ranging between 6.4 and 8.4 m below ground and over 3 years of sampling were amplified for amplicon pyrosequencing using the primers Ba27f (5’-aga gtt tga tcm tgg ctc ag-3’) and Ba519r (5’- tat tac cgc ggc kgc tg-3’), extended as amplicon fusion primers with respective primer A or B adapters, key sequence and multiplex identifiers (MID) as recommended by 454/Roche. Amplicons were purified and pooled as specified by the manufacturer. Emulsion PCR (emPCR), purification of DNA-enriched beads and sequencing run were performed following protocols and using a 2nd generation pyrosequencer (454 GS FLX Titanium, Roche) as recommended by the developer. Quality filtering of the pyrosequencing reads was performed using the automatic amplicon pipeline of the GS Run Processor (Roche), with a slight modification concerning the valley filter (vfScanAllFlows false instead of TiOnly) to extract the sequences. Demultiplexed raw reads were furhter trimmed for quality and lenght (>250 bp).

Project description:The synthesis of starch-like glucans can be reconstituted in S. cerevisiae using the genes from Arabidopsis thaliana: heterologous expression of SS1 to SS4, BE2, BE3, ISA1, and ISA2, together with a bacterial ADPglucose pyrophosphorylase gene for substrate provision in yeast strain 29, yielded insoluble granules with a semi-crystalline structure similar to that of plant amylopectin (Pfister et al., 2016). Here we conducted a label-free proteomics experiment to compare yeast strains with and without glucan production. This experiment was performed on strains 29, 48A, 362.1, 363.1 and WT (n = 4 replicates each, arising from independent replicate cultures). Strains including genotypes are described in the associated publication.
