Project description:Obesity is associated with various diseases such as metabolic disorders, joint problems, and inflammations. Over 50% of pets, including dogs and cats, are obese, making a comparative study necessary at gene level. Since circulating peripheral blood mononuclear cells (PBMCs) reflect the organs related to obesity, we compared the mRNA expression in normal and obese PBMCs of dogs. Our findings show that there are 425 differentially expressed genes (DEGs) (p < 0.05, |log2 fold| ≥ 1) that exhibit distinct gene expression between normal and obese PBMCs. In Kyoto encyclopedia of genes and genomes (KEGG) and Ingenuity Pathway Analysis (IPA) indicate that obesity affect the PBMC cell cycle through FoxM1. These results suggest that obesity causes functional change of PBMCs through cell cycle regulation. In conclusion, obesity suppresses the PBMCs-mediated immune response through FoxM1.
Project description:The integrity of the epithelium is maintained by a complex but regulated interplay of processes that allow seamless orchestration of a proliferative state into a stably differentiated state. In this study, using stem cell derived Retinal Pigment Epithelium (RPE) cells as a model; we have investigated the molecular mechanisms that affect attainment of the epithelial phenotype. We identify a novel role for the proto-oncogene FOXM1 in determining epithelial fate of RPE by directly regulating cell proliferation and by indirectly regulating expression of signalling factors BMP7 and Wnt5B; both of which are intimately required for eventual acquisition of the epithelial phenotype. This study uncovers the role of FOXM1 in a non-oncogenic, native-like setting and shows that human ES derived RPE can serve as a useful model system to address biological questions not restricted to visual function.
Project description:Primary human peripheral blood mononuclear cells were isolated from full blood by standard ficoll centrifugation. Cells were washed and processed immediately.
Project description:Ankylosing spondylitis (AS) is an inflammatory arthritis of the axial skeleton that predominantly affects young men. HLA-B27 has remained the major genetic risk factor in AS. Recently, more non-MHC genes has been discoverd to be involved in AS pathogenesis, especially IL-23 signalling pathway related genes. We performed a proteomic study of the peripheral blood mononuclear cells from AS patients and healthy donors.
Project description:Transcriptome profiling was conducted on 2 replicate samples of total peripheral blood mononuclear cells (PBMC) and isolated PBMC subsets.
Project description:Study goal is to disclose features of gene expression profile of peripheral blood mononuclear cells obtained from type C cirrhotic patients with or without hepatocellular carcinomas. Keywords: gene expression profile, peripheral blood mononuclear cells, type C liver cirrhosis
