Project description:Bacterial cell envelope is the first and the major line of defense against threats from the environment. Because of its crucial roles in bacterial cell life, cell envelope is a prime target for numerous antibiotics. In this study, by treating Gram-positive model strain Bacillus subtilis with numbers of cell wall targeted antibiotics, we aimed to obtain a global comprehensive transcriptional profile of cell envelope stress response in B. subtilis via transcriptomic study using high-throughput RNA sequencing approach. This knowledge will then be subject to a series of comparative genomics analyses to get detailed information of the distribution and conservation of cell envelope stress-sensing regulatory systems in B. subtilis.
Project description:Leveraging the conserved cancer genomes across mammals has the potential to transform driver gene discovery in orphan cancers. Here, we combine cross-species genomics with validation across human-dog-mouse systems to uncover a new osteosarcoma driver genes. This widely applicable cross-species approach serves as a platform to expedite search of cancer drivers in rare human malignancies offering new targets for cancer therapy.
Project description:We discovered Daxx can negatively regulated H3K27me3 level via facilitating long non-coding RNA HOTAIR degradation. To further explore the biological consequence and search for affected genes, we used high throughput sequencing technology to demonstrate the enrichment of H3K27me3 on the human genome and target genes repression after depletion of Daxx. This study revealed a novel role of Daxx in regulating histone modifications via modulates long non-coding RNA stability.
Project description:CS Baby Biome randomized control trial aims to investigate if the timing of intrapartum antibiotics given to mother influences the infant gut microbiome composition. The study was performed in women delivering via elective CS, who received antibiotics prior to skin incision, or after umbilical cord clamping.
Project description:A systems biology approach in which qualitative modeling based on combining boolean networks and in silico perturbation experiments were employed to identify 15 pluripotency regulating cytokines or cytokine related genes. IL-11 was validated as a novel factor capable of maintaing the undifferentiated state of human embryonic stem cells in the absence of exogenously added bFGF to the culture acting via a different mechanims than bFGF.
