Project description:The main goal of the project is the study the associations between the gut metagenome and human health. The dataset contains data for n=7211 FINRISK 2002 participants who underwent fecal sampling. Demultiplexed shallow shotgun metagenomic sequences were quality filtered and adapter trimmed using Atropos (Didion et al., 2017), and human filtered using Bowtie2 (Langmead and Salzberg, 2012).

Project description:Human DNA present in fecal samples can result in a small number of human reads in gut shotgun metagenomic sequencing data. However, it is currently unclear how much personal information can be reconstructed from such reads and this has not been quantitatively evaluated. Such a quantitative evaluation is necessary to clarify the ethical concerns related to data sharing and to enable the efficient use of human genetic information in stool samples, such as for research and forensics. Here, we used genomic approaches to reconstruct personal information from fecal metagenomes of 343 Japanese individuals with associated human genotype data. Our approach can be used to quantify the personal information contained within gut metagenome data.
Project description:The aim of this study was to investigate the effect of early calf-hood nutrition on the transcriptomic profile of the arcuate nucleus of the hypothalamus, the anterior pituitary and the testes in Holstein-Friesian bulls and possible downstream effects on reproduction. Holstein Friesian bull calves with a mean (±S.D.) age and bodyweight of 19 (±8.2) days and 47.5 (±5.3) kg, respectively, were assigned to either a high (n=10) or low (n=10) plane of nutrition. Calves were fed in order to achieve an overall growth rate of 1.2 and 0.5 kg/day for the high and low plane of nutrition treatments, respectively. At 126 days of age, the bulls were euthanized using an intravenous overdose of sodium pentobarbitone and arcuate nucleus of the hypothalamus, anterior pituitary and the parenchyma of the testes tissue samples were harvested and RNAseq analysis was performed. At the end of the trial period,
