Project description:In the present study, we investigated the effect of Lactobacillus lactis on healthspan using Caenorhabditis elegans as a model animal. The healthspan of the adult C. elegans fed the mixture of E. coli OP50 and Lactobacillus lactis NBRC 100913 or NBRC 12007 strains was significantly longer than that of animals fed sole OP50 (control). Transcriptional profiling comparing Lactobacillus lactis- and control-fed animals suggested that genes related to “locomotion” were upregulated by Lactobacillus lactis.
Project description:Varicella-zoster virus (VZV), an alphaherpesvirus, causes chickenpox (varicella) in young children with an annual minimum of 140 million new cases and herpes zoster in senior, a painful and debilitating disease with 3-5‰ incidence. A complex structural transcriptome of VZV, which numerous novel transcripts, transcript isoforms, and unknown splice events are found during cell infection. Circular RNA (circRNA), a newly important component of the transcriptome, is increasing discoveries of circRNA function in mammalian cells. However, VZV encoded circRNA remains unexplored. The code used in this study and extended data are available from the GitHub repository (https://github.com/ShaominYang/VZV_circRNA)
Project description:The presence of tagatose in Lactobacillus rhamnosus strain GG caused induction of a large number of genes associated with carbohydrate metabolism including the phosphotransferase system. In addition, these results indicate the tagatose enhanced the growth of Lactobacillus casei 01 and Lactobacillus rhamnosus strain GG and their probiotic activities by activating tagatose-associated PTS networks. Two-condition experiment, Lactobacillus rhamnosus GG with glucose vs. Lactobacillus rhamnosus GG with tagatose. For preparing the total RNA, Lactobacillus rhamnosus GG cells were grown at 37M-BM-0C in prebiotic minimum medium supplemented with 2% glucose or tagatose for 24 h.

Project description:DNA methylation is an important epigenetic modification. DNA methylation phenomenon exists widely in bacteria, plants and animals and is involved in a variety of biological processes.The wild Lactobacillus casei Zhang and its mutant Lactobacillus casei Zhang Δpglx were used as the research subjects.Proteomics was used to explore the effects of DNA methylation on various aspects of Lactobacillus casei.
Project description:Age-related hearing loss is a multifactorial and progressive process, which negatively impacts quality of life in many senior adults as the number one chronic neurodegenerative condition. This study was done to examine gene expression changes occurring in mouse auditory nerve and cochlear lateral wall tissues that may contribute to age-related hearing loss. In addition to conducting general differential expression analysis, a focused analysis of genes linked to neural cells was done.
Project description:We transplanted Klebsiella and Lactobacillus to germ free C57/B6J mice. All of the recipients mice were male. Here we report the intestine mRNA profiles of recipients mice with Klebsiella and Lactobacillus.
