Investigation of a Quality Check for Plasma Samples

ABSTRACT: Plasma samples from healthy volunteers were used for the microarray analysis. The fresh sample and intentionally hemolyzed one due to negative pressure were examined. Microarray analyses were performed using the 3D-Gene microRNA microarray platform, and RNA extraction was conducted according to the manufacturerâs instructions. Only a very small amount of total RNA was present in the plasma samples; therefore 2 out of the 4 Âµl of total RNA extracted from 300- Âµl of plasma samples were used in microarray experiments. The purpose of this study is to identify hemolysis related microRNA. Plasma samples from healthy volunteers were used for the microarray analysis. The fresh sample and intentionally hemolyzed one due to negative pressure were examined.

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

Study of microRNA associated with the anti-tumor effect of gemcitabine

Project description:The miRNAs expression was markedly altered with the treatment of gemcitabine on human CCC cells in vitro. And various miRNAs induced by gemcitabine may contribute to tumor regression in vitro. Using a custom microarray platform, we analyzed the expression levels of 2555 human miRNA probes in the cell lines in vitro that were treated with and without gemcitabine.

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.

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

Project description: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.

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.
