Mouse bone marrow stromal cells: before or after total body irradiation

ABSTRACT: Comprehensive gene expression analysis in BM-resident stromal cells was performed for an overview of BM environmental change caused by total body irradiation (TBI). Total RNA samples collected from BM-resident stromal cells with or without TBI were subjected to high sensitivity DNA microarray assays Three-condition experiment: Unirradiated, 1 day after TBI and 3 days after TBI. Bone marrow stromal cells were obtained from C57BL/6 mice (n = 6) either non-irradiated or after 9.5 Gy irradiation at indicated times.

Project description:Microarray was performed to comprehensively examine microRNA induction in murine small intestine after exposure to total body g-irradiation. Small intestines were collected from Tlr3+/+ and Tlr3-/- mice at 0 and 6 hr after exposure to 10 Gy of total body g-irradiation. Samples were pooled from 3 mice. Total RNA was extracted and subjected to microRNA microarray analysis.

miRNA expression profile of cells and exosomes

Project description:We hypothesized that miRNAs in the bone maroow mesenchymal stem cells (BM-MSC)-derived exosomes contributed to the phenotype change of breast cancer cells through exosome transfer. We analyzed the miRNA expression signature in BM-MSC-derived exosomes. We compared the miRNA expression levels in exosomes between BM-MSCs and adult fibroblasts (as a control). In this study, miRNA expression including in bone-marrow mesenchymal cell (BM-MSC)-derived exosomes was examined, and compared with that of exosomes derived from adult fibroblast cells or the BM-MSC cells. In addition, miRNA expression of BM-MSC exosomes was also compared with that of breast cancer cells with or without cancer stem cell marker.

Gene expression profiling of endothelial cells derived from Foxo1(+/+) and Foxo1(-/-) ES cells in response to VEGF

Project description:VEGF induces elongation of endothelial cells (ECs) that are derived from wild-type (Foxo1(+/+)) ES cells. VEGF-induced EC elongation is an important process of angiogenesis. ECs derived from Foxo1(-/-) ES cells fail to elongate in response to VEGF. Gene expression profiling of wild-type and Foxo1(-/-) ECs in the presence or absence of VEGF stimulation identifies responsible genes that regulate EC elongation. One wild-type (Foxo1(+/+)) ES cell clone and one Foxo1(-/-) ES cell clone were used. ES cells were cultured on OP9 stromal cell layer in the presence or absence of VEGF (10 ng/ml). After 6.5 days, VE-cadherin+ CD31+ ECs were isolated by FACS and used for total RNA extraction. Three independent experiments were performed for each condition.

Lhx2-regulated genes in hematopoietic stem cell (HSC)-like cells differentiated from mouse embryonic stem (ES) cells

Project description:We previously demonstrated that hematopoietic stem cell (HSC)-like cells are robustly expanded from mouse embryonic stem (ES) cells by enforced expression of Lhx2, a LIM-homeobox domain (LIM-HD) transcription factor. Here we established an ES cell line which conditionally expressed Lhx2 by Tet-On system. The ES cells were differentiated into HSC-like cells by Lhx2 expression. Lhx2-regulated genes were identified by comparing the HSC-like cells with those cultured in the absence of Lhx2 expression. Mouse ES with inducible Lhx2 were differentiated on OP9 stromal cells into hematopoietic lineage. On day 5 of the differentiation induction,Lhx2 expression was started by the addition of doxycycline (dox) and the cells were cultured on OP9 stromal cells in the presence of IL-6 and SCF. On day 20, HSC-like cells were harvested and re-seeded onto OP9 stromal cells in the absence of Lhx2 expression by dox-removal for 3 days. these cells were compared with the original HSC-like cells.

Circulating microRNA profiles in patients with type-1 autoimmune hepatitis

Project description:Recent studies have demonstrated that micro (mi)RNA molecules can be detected in the circulation and can serve as potential biomarkers of various diseases. This study used microarray analysis to identify aberrantly expressed circulating miRNAs in patients with type 1 autoimmune hepatitis (AIH) compared with healthy controls. Patients with well-documented and untreated AIH were selected from the National Hospital Organization (NHO)-AIH-liver-network database. They underwent blood sampling and liver biopsy with inflammation grading and fibrosis staging before receiving treatment. To further confirm the microarray data, circulating expression levels of miR-21 and miR-122 were quantified by real-time quantitative polymerase chain reaction in 46 AIH patients, 40 patients with chronic hepatitis C (CHC), and 15 healthy controls. Consistent with the microarray data, serum levels of miR-21 were significantly elevated in AIH patients compared with CHC patients and healthy controls. miR-21 and miR-122 serum levels correlated with alanine aminotransferase levels. Circulating levels of miR-21 and miR-122 were significantly reduced in AIH patients with liver cirrhosis, and were inversely correlated with increased stages of fibrosis. By contrast, levels of circulating miR-21 showed a significant correlation with the histological grades of inflammation in AIH. We postulate that aberrantly expressed serum miRNAs are potential biomarkers of AIH and could be implicated in AIH pathogenesis. Alternations of miR-21 and miR-122 serum levels could reflect their putative roles in the mediation of inflammatory processes in AIH. Case-control study, steroid treatment

The change of mRNA expression in murine immortalized podocyte after miR-26a silencing

Project description:The change of mRNA expression in murine immortalized podocyte were analyzed after miR-26a silencing. These results provide a basical information of molecular pathology in podocyte biology. Mouse podocytes immortalized by temperature sensitive SV40 were used. Podocyte cultures grown at 33 °C were trypsinized and then cultured with RPMI-1640 without antibiotics in 24-well plates at 60–70% confluence for 2 days. On day 3, an anti-miR negative control (40 pmol) or the miR-26a miRNA inhibitor (40 pmol) was transfected to podocytes. The cells were analyzed after culturing for 24 hour.

Analysis of therapeutic miRNA against KRAS mutant colorectal cancer

Project description:We compared the profile of miRNAs expressed in HEK293 and MRC5 cells that overexpressed KRASG12V to those expressed in parental cells that harbored wild-type KRAS. The results indicated that a subset of miRNAs was significantly down-regulated in KRASG12V transfected two cells. To address the functional relevance of miRNAs in KRAS mutant cancers, we transfected exogenous KRASG12V into HEK293 and MRC5 cells with wild type KRAS genes, and we comprehensively profiled the dysregulated miRNAs.
