Project description:Purpose: The goal of this study is using RNA sequencing analysis to evaluate the role of lactoferrin in the LPS-induced acute inflammation in mouse Methods: 4 hs after intraperitoneal injection with LPS(4mg/kg) or equal volume PBS , the peritoneal cells were isolated from the peritoneal lavage fluid from wild type and lactoferrin knockout mice (n=3 for each group) . Then the cell RNA was sequenced by the HiSeq 2500 high-throughput sequencing service (Oebiotech, Shanghai, China). Data were extracted and normalized according to the manufacturer’s standard protocol. Results: Log-fold changes of up- or down-regulated mRNAs between the control and experiment group were selected with a significance threshold of p<0.05. Conclusions: Our study describes the mRNA expression profile changes of peritoneal cells from wild type and lactoferrin knockout mice during LPS-induced acute inflammation
Project description:To characterize the metabolic profile of peritoneal endothelial cells (ECs) in response to peritoneal dialysis (PD), we performed RNA sequencing of peritoneal ECs isolated from mice treated with PD fluid for 6 weeks (n = 3) and from mice treated with saline for 6 weeks (n = 3). We demonstrated that peritoneal ECs had a hyperglycolytic metabolism in response to PD fluid treatment, which is associated with the development of microvascular alterations and peritoneal dysfunction.
Project description:Purpose: Characterize the gene expression profile of of peritoneal mouse macrophages in Endotoxic shock and Tolerance through RNA sequencing Methods: RNA sequencing of RNA from peritoneal macrophages in Endotoxic shock and Tolerance isolated by peritoneal lavage and FACS sorting (F4/80+ CD11b+) Results: Endotoxic shock and Tolerance peritoneal mouse macrophages display differential gene expression. Conclusions: Endotoxic shock and Tolerance peritoneal mouse macrophages display differential gene expression.
Project description:Purpose: This study was undertaken to evaluate the effect of peritoneal fluid from subjects with differing stages of endometriosis on gene expression in endometrial stromal cells. Methods: Peritoneal fluid from subjects with minimal, moderate, and severe stages of endometriosis or without endometriosis (controls) was collected, filtered and separated from peritoneal cells. Telomerase – immortalized human endometrial stromal cells (T-HESC) were treated with the peritoneal fluid samples for 48 hours. RNA was isolated from treated cells and processed for DNA microarray. Results: 162 genes were found to be differentially expressed in T-HESC cells treated with peritoneal fluid from subjects with differing stages of endometriosis. Three of the differentially expressed genes were chosen for confirmatory studies using quantitative RT-PCR; these were interleukin 8, corin and matrix metalloproteinase 3. The primary gene ontologies identified by microarray highlight functions expected to be involved in the establishment of endometriosis, such as proteases, signal transduction, defense and immune system, cell adhesion, cell cycle and cell death, cytoskeleton, transcriptional regulation and translation, extracellular matrix, and enzymes and metabolism. Conclusions: This study demonstrated that the severity of endometriosis affected the factors present in peritoneal fluid which, in turn, affected gene expression in endometrial stromal cells.
Project description:We performed small RNA sequencing on extracellular vesicles isolated from bronchoalveolar lavage fluid (BALF) collected from ozone and filtered air exposed C57BL/6J mice
Project description:Analysis of early and late changes in the mouse peritoneal cells in response to E. coli induced sepis. Result provide an insight into the molecular function and pathways expressed at these different time points. The mice were divided in two groups; the first group of mice were not treated with E. coli and was referred to as the naive group. Each mouse of the second group was injected with 2 X108 cells of a non- pathogenic isolate of E. coli suspended in a phosphate buffered saline (PBS) solution. After 1h, 2h and 18h of E. coli administration, peritoneal lavage fluid was obtained from two mice each for E. coli treated group at 1 and 2h and three mice of both groups (control and E. coli treated) at 18h. A common naive group of 2 mice harvested at 2h served as a control for both 1h and 2h.
