Project description:To collect human tissue, blood, and fecal samples from patients suffering from Inflammatory Bowel Disease and Colorectal Cancer. The samples will be used to establish biomimetic human organ-on-a-chip technology, as well as study the role of the microbiome in the pathogenesis in human gastrointestinal diseases.
Project description:Serial analysis of gene expression (SAGE) was used to get a global view of the gene profile in human hippocampus. A library were generated from control hippocampus, obtained by rapid autopsy. Keywords: hippocampus human inventory genes
Project description:Left-right asymmetry is a basic character of aging brain; however, the molecular foundation of the left-right asymmetry remains unclear. The morphology, physiology and behavior of rhesus aging are obviously similar to human aging, but the aging-rate of rhesus is roughly three times as fast as human, in which the underlying mechanism needs further investigation. By using of 6-plex tandem mass tag (TMT) labeling, we presented a high throughput quantitative proteomics analysis to 6 group hippocampal samples including left and right hippocampus from 3 years, 6 years and 20 years old rhesus. Our data identified 3391 high-confidence proteins. After screening, we found 340 aging-related proteins of left hippocampus and 334 aging-related proteins of right hippocampus, in which there were 114 overlap proteins. Furthermore, the aging-related proteome of left rhesus hippocampus aging was compared with human aging-related proteome of left hippocampus that was reported by our lab previously. As the results show, we discovered 446 aging-related proteins in rhesus and 830 aging-related proteins in human with an overlap of 106 proteins.
Project description:Human hippocampus enabled further processing of higher brain functions. However, very little is known about human hippocampus development, which is largely accomplished during fetal stage. Our current study elucidates the transcriptomic profiling of the developing human fetal hippocampus using single-cell RNA-seq (scRNA-seq) and bulk atac-seq, allowing us to reconstruct the order of neurogenesis and their lineage relationships.
