Project description:Gene expression in RAW 264.7 cells on treatment with Lactobacillus acidophilus, Bacillus clausii and Bifidobacterium bifidum at MOI of 1 for 6 hours.
Project description:We explored the transcriptional response of Faecalibacterium prausnitzii A2-165 when exposed to cell-free supernatants from different Lactobacillus, Streptococcus and Lactococcus strains. For that, we sequenced its RNA and looked for significant differences in the expression levels among the supernatants groups.
Project description:We established three new rhesus embryonic stem cells lines and conducted their microRNA profilings by Solexa sequencing. Sequencing of small RNA libraries yielded 12.66 million, 13.12 million and 11.57 million raw reads from IVF1.2, IVF3.2 and IVF3.3, respectively. After filtering, we obtained 10.89 million (IVF1.2), 10.60 million (IVF3.2) and 9.26 million (IVF3.3) clean reads (18-30nt).
Project description:Goal: To identify small RNA associated with the decision of undifferentiated spermatogonia to commit to a pathway of differentiation. Methods: testis small RNA profiles of 6 juvenile wild-type rhesus monkeys (3 vehicle-treated; 3 gonadotropin treated) were generated by deep sequencing, in triplicate, using Ion Torrent. The sequence reads that passed filters were analyzed with miRDeep2, HTSeq counts and edgeR. qRT–PCR validation was performed using SYBR Green assays Results: We mapped about 3 million sequence reads per sample to the rhesus monkey genome (rheMac 2 and rheMac 8.0.1) and identified 932 small RNAs in the testes of wild type monkeys with Bowtie and miRDeep2 workflow. Approximately a combined 7% of unique transcripts showed differential expression between vehicle and gonadotropin treatment for 48 and 96h, with a fold change ≥1.5 and p value <0.05. Altered expression of 12 genes was confirmed with qRT–PCR, substantiating the RNA-seq findings. Conclusions: The testis transcriptome of the juvenile monkey contained 932 non coding smallRNA. Gonadotropin stimulation for 48 h resulted in the commitment of spermatogonia to differentiate and this was associated with the emergence of 51 differentially expressed genes.

Project description:Gene expression in THP-1 cells on treatment with Lactobacillus acidophilus, Bacillus clausii and Bifidobacterium bifidum at MOI of 1 for 6 hours.
Project description:Purpose: To understand the metabolic mechanism of Lactobacillus salivarius Ren in raffinose Methods: Samples of Lactobacillus salivarius Ren grown in glucose and raffinose were sequenced on the Illumina Hiseq platform. Three independent biological replicates were generated, including a total of six samples. Results: Raw data were firstly processed through in-house perl scripts to generate clean data, and then clean date were mapped to the reference genome, getting about 8-10 million total mapped reads per sample.
Project description:To characterize how symbiotic bacteria affect the lolecular and cellular mechanisms of epithelial homeostasis, human colonic Caco-2 cells were co-culture with Lactobacillus casei and Bifidobacterium breve.
